    [1" class="description-paragraph] CTASTRIC TUBE RETAINERThe present invention relates to tracheal and gastric tube assemblies, to retainers for gastric tubes and to methods of retaining gastric tubes.A gastric tube, commonly called a Salem tube, is a hollow plastic tube usually made of polyvinylchloride (PVC), that is inserted through the nose or mouth, down the back of the throat, through the esophagus and into the stomach. Gastric tubes are commonly used in the treatment of patients in order to provide nutrition and/or for stomach emptying. Generally, gastric tubes inserted into the stomach are made stiff to resist collapsing when suction is applied. Gastric emptying is effected to prevent vomiting or to monitor how well a patient is tolerating being fed into the stomach. If the patient is not tolerating being fed into the stomach, the patient may tolerate being fed into the duodenum (past the stomach) via a longer duodenal tube. This duodenal feeding tube is made smaller, thinner and softer than a gastric tube because it is used just for feeding and not for stomach emptying. The duodenal feeding tube is weighted on its end and has a guide wire to aid the clinician in inserting this tube into the duodenum.Gastric tubes are available in 6 common sizes: 8, 10, 12, 14, 16, and 18 French (roughly 0.08 to 0.24 inches in outer diameter). The choice in size to use for a patient may relate to the size of the patient or the primary purpose of the gastric tube. Generally, for unconscious patients, bigger tubes are easier to insert, as they are more rigid and therefore resists curling in the oropharynx. Larger tubes also have less resistance and promote better flow and have less chance of obstructing.The securing of gastric tubes to critically ill patients has been a problem for many years. Past and current devices used to secure gastric tubes usually comprise an adhesive material. Tape is widely used because it is ine~:pensive and readily available. Different types of tape can be
    [2" class="description-paragraph] 2 used and it is usually wrapped ~~round the gastric tube and then stuck to the patient's nose or face.However, tape may come loose; or may cause pressure sores by holding the gastric tube too tightly to the nostril and the patient can pull his/her gastric tube out fairly easily if it is only taped in place. Tape provides an inconsistent hold, depending on the type of tape used and the technique for applying it. Also, the presence of moisture and/or oil from the patient's skin can cause tape to loosen with tune. As a backup, some hospitals tape the gastric tube directly to the tracheal tube, if the patient is intubated, or use a safety pin with tape to secure the gastric tube to the patient's gown, providing additional security.When using gloves, tape is difEcult to handle, requiring the clinician to expose his or her hands to potentially infectious body fluids. Overall, tape is difficult to work with, takes longer to apply, and gives the patient an alarming appearance. Also, allergic reactions, skin irritations and nasal tissue necrosis have been reported form the use of tape. Replacing gastric tubes, and especially duodenal feeding tubes, is time consuming and costly making it important to use a secure and. reliable device.If gastric tubes are taped to thf; tracheal tube, however, this obscures the reference marks along the tracheal tube and makes for difficult repositioning. Some tracheal tubes are accidentally cut too short prior to insertion, so that the hub of the tracheal tube is almost level with the patient's face. In this case, the gastric tube is usually just taped to the face of the patient.According to the present invention, there is provided a gastric tube retainer, comprising a lamina of plastic material and a tracheal tube opening in said lamina for receiving a tracheal tube, said lamina including a gastric tube engagement portion releasibly engageable with a gastric tube.
    [3" class="description-paragraph] 3 In use, the retainer is firstly attached to a tracheal tube, with the tracheal tube extending through the tracheal tube opening, and the gastric tube engagement portion is then engaged with a gastric tube, so that the latter becomes secured to the tracheal tube.In a preferred embodiment of the present invention, the gastric tube engagement portion has a gastric tube opening for receiving the gastric tube and a slit extending from the gastric tube opening to an edge of the gastric tube engagement portion, the gastxic tube engagement portion being resiliently flexible to open the slit to permit insertion of the gastric tube through the slit with the gastric; tube opening.The invention will be more readily understood from the following description thereof, when taken in conjunction with the accompanying drawings, in which:Fig. 1 is a perspective view of a gastric tube retainer embodying the present invention;Fig. 2 is an exploded perspective view illustrating a step in the assembly of the retainer of Fig. 1 with a tracheal tube;Fig. 3 shows a view in perspective of a completed assembly of the retainer and the tracheal tube of Fig. 2;Fig. 4 shows a view similar to that of Fig. 3 but with the retainer being flexed to allow a gastric tube to be engaged with the retainer;Fig. 5 shows a view similar to that of Fig. 4 but with the gastric tube engaged and held by the retainer;Fig. 6 shows a modification of tike retainer of Fig. 1 for use with gastric tubes of two different sizes;
    [4" class="description-paragraph] 4 Fig. 7 shows a plan view of a further modification of the retainer of Fig. 1; and Fig. 8 shows a view in side elevation of the retainer of Fig. 7.Figures 1 and 2 show a gastric tube retainer, indicated generally by reference numeral 10, which comprises a flat sheet or strip-shaped plastic material piece or lamina. One end 11 of the retainer 10 is rounded at the periphery of the retainer 10, for safety, and has a tracheal tube opening 14. An opposite: end forms a gastric tube engagement portion indicated generally by reference numeral 16, which includes a gastric tube opening 18, and a pair of flaps 20 separated by a slit 22 extending from the gastric tube opening 20 to the periphery of the retainer 10.To assemble the retainer 10 on a tracheal tube indicated generally by reference numeral 24, the latter is disconnected into two parts at an swivel or elbow adapter, as shown in Figure 2.A hub 26 forming one of these .disconnected parts is then inserted through the tracheal tube opening 14 in frictional engagement with the retainer 10, which is stopped by a flange 30 of the tracheal tube 24. An elbow or swivel adapter 32 forming the other disconnected part of the tracheal tube 24 is then reconnected to the hub 26, as shown in Figure 3.Then, as shown in Figure 4, the engagement portion 16, which is resiliently flexible, is flexed to separate the flaps 20 and open the slit 22 and thereby to permit a gastric tube 34 to be inserted through the slit 22 into the gastric tube opening 18. The flaps 20, when released, return resiliently to their original positions, so that the gastric tube engagement portion 16 is thereby releasibly engaged around the gastric tube 34.The retainer 10 is thin enough so as not to impede the fit between the elbow connector/swivel adapter 32 and the hub 26 of the: tracheal tube 24. The gastric tube 34 is secure in the retainer 10 since the gastric tube opening 18 has a diameter smaller than the outer diameter of the gastric tube 34. Figure 6 shows a modification of the retainer 10, indicated generally by reference numeral 110, which has a gastric tube opening 118 and a slit 122 corresponding to the opening 18 and the slit 22 of Figure I and a further gastric tube opening 124, which has a larger diameter than the opening 118 so as to fi.t a correspondingly larger gastric tube outer diameter, and a
    [5" class="description-paragraph] 5 further slit 126 extending from the opening 124. The slits 122 and 124 in Figure 6 are spaced far enough apart so as not to impede the resilient memory of the retainer 110. The slits 122 and 124 differ in length so thal: the openings 118 and 124 can be spaced apart sufficiently without having to make the retainer 110 wider.The modified retainer of Figure's 7 and 8, which is indicated generally by reference numeral 210, comprises a flat and circular disc-shaped retainer formed with six gastric tube openings 21 8a-f of different sizes, for receiving six correspondingly differently sized gastric tubes (not shown). Each of the openings 218a- f has a respective slit 222a- f extending from it to the periphery of the retainer 210, the openings 21 8a-f and the slits 222a-f being distributed around a central tracheal tube opening 214 so that, in this embodiment of the present invention, the gastric tube engagement portion is an annular portion of the retainer 210 extending around the opening 214.In use, one of the above-described retainers is pushed onto the tracheal tube hub after a patient has been intubated. The swivel or elbow adapter of the ventilating circuit is then connected to the hub so the patient can be ventilated. The gastric tube is then inserted into the patient via the mouth or nose. 'the gastric tube is then engaged in the retainer as described above.The tracheal tube acts as an anchor once the gastric tube is engaged into the retainer and by situating the retainer on the tracheal tube, some complications associated with tape can be avoided. There is no added discomfort or significant weight to the tracheal tube from the retainer and the retainer is metal and latex-free, making it safe for X-rays and MRI. The retainer allows quick positiona:l adjustments of the gastric tube, thus saving valuable time.
    [6" class="description-paragraph] 6 Moreover, the retainer will he'.lp prevent the costs and discomfort associated with the re-insertion of gastric tubes in intubated patients. The present invention avoids the use of unreliable adhesive materials for attachment, and can provide a consistent securement for an extended period of time. Unlike: most other holding means, the present retainer does not have to touch the patient, thus avoiding possible discomfort to the patient.The present retainer is particularly suitable for holding a gastric tube inserted through the mouth since, in that case, the gastric tube cannot be taped to the patient's nose. When the retainer is in use and the gastric tube is pulled, the retainer is designed to flex and hold instead of letting the gastric tuba slide through. The present retainers will secure gastric tubes fast, provide quick repositioning and will last longer than tape.
