Abstract
Description
Technical Field
[0001] The utility model relates to an auxiliary catheter for inserting a gastrointestinal nutrient tube, belonging to the technical field of digestive science. Background Art
[0002] The section from the mouth to the esophagus is the difficult part in the placement of the gastrointestinal nutrition tube. Since the gastrointestinal nutrition tube is relatively soft and the patient is under general anesthesia, it is difficult to enter the esophagus in the predetermined direction. The operation is difficult and requires multiple operations for successful insertion.
[0003] In order to facilitate the insertion of the gastrointestinal nutrition tube, a hard catheter is first inserted, and then the gastrointestinal nutrition tube is inserted into the designated position through the catheter. Although the gastrointestinal nutrition tube can be inserted quickly, the tail of the gastrointestinal nutrition tube is a large tube head, which will get stuck in the tube head, making it impossible to directly remove the tube. The existing operation is to cut the tube a little bit and then remove it. The whole process is demanding and the operation process is cumbersome. Utility Model Content
[0004] The technical problem to be solved by the utility model is to provide an auxiliary catheter for inserting a gastrointestinal nutrition tube. The auxiliary catheter adopts an easily tearable connection part. After the gastrointestinal nutrition tube is inserted, the connection part can be quickly opened to remove the tube, which greatly reduces the difficulty of removing the tube.
[0005] The utility model is realized by the following scheme: an auxiliary catheter for inserting a gastrointestinal nutrition tube comprises a catheter body and a connecting part, wherein the catheter body is a tubular structure, a connecting groove is opened on the tube wall of the catheter body, and the connecting part is connected to the connecting groove.
[0006] The connecting portion comprises a tear strip and a pull strip, the right side of the tear strip is connected to the pull strip, the upper and lower ends of the tear strip are both connected with connecting teeth, and the connecting teeth are connected to the connecting groove.
[0007] The tear strip has the same length as the catheter body.
[0008] The right side of the pull strip is connected to a pull ring.
[0009] The connecting portion is a zipper mechanism.
[0010] A protective film is provided on the upper side of the zipper mechanism, and the protective film is connected to the upper portion of the inner wall of the connecting groove.
[0011] The catheter body is made of PVC material.
[0012] The beneficial effects of the utility model are:
[0013] The utility model discloses an auxiliary catheter for inserting a gastrointestinal nutrition tube, which adopts an easily tearable connection part, wherein the connection part is a tear strip or a zipper mechanism connected in a toothed shape, so that the connection part can be quickly opened after the gastrointestinal nutrition tube is inserted, and then the tube can be taken out, which greatly reduces the difficulty of taking out the tube.

DETAILED DESCRIPTION
[0021] Combine the following Figure 1-6 The utility model is further described, but the protection scope of the utility model is not limited to the described contents.
[0022] Example 1
[0023] Reference Figure 1 An auxiliary catheter for inserting a gastrointestinal nutrition tube includes a catheter body 100 and a connecting part 200. The catheter body 100 is a tubular structure with a diameter of 6.00 mm and a length of 30 cm. A connecting groove 101 is opened on the tube wall of the catheter body 100, and the connecting part 200 is connected to the connecting groove 101.
[0024] Reference Figure 2, the connecting part 200 includes a tearing strip 201 and a pulling strip 202. The right side of the tearing strip 201 is connected to the pulling strip 202. Connecting teeth 203 are connected to both the upper and lower ends of the tearing strip 201, and the connecting teeth 203 are connected to the connecting groove 101.
[0025] The connecting teeth 203 are of a one-way barbed structure, arranged at intervals along the length direction of the tearing strip 201, with a tooth height of 0.3 - 0.5 mm and a tooth pitch of 2 - 3 mm; the connecting teeth 203 and the connecting groove 101 form a detachable clamping fit. When the tearing strip 201 is subjected to an axial pulling force, the connecting teeth 203 can be successively disengaged from the connecting groove 101.
[0026] The length of the tearing strip 201 is the same as the length of the catheter main body 100, and the thickness of the tearing strip 201 is less than the thickness of the catheter main body 100.
[0027] The catheter main body 100 is made of PVC material and has a certain hardness.
[0028] Refer to Figure 3 , during the insertion operation of the enteral nutrition tube 300, first insert the auxiliary catheter into the patient's body, then insert the enteral nutrition tube 300 into the catheter main body 100 and further into the patient's body. When the enteral nutrition tube 300 is inserted into the required position, the nurse holds the pulling strip 202 and applies force to tear the tearing strip 201. Since the tearing strip 201 is connected in the connecting groove 101 through the connecting teeth 203, the tearing strip 201 can be quickly and conveniently torn off, and then the catheter main body 100 is withdrawn from the patient's body, thus completing the operation of inserting the enteral nutrition tube 300.
[0029] During operation, hold the holding part and apply force along the axial direction of the catheter. The connecting teeth 203 are successively disengaged from the connecting groove 101, so that the tearing strip 201 is completely peeled off along the pre-cutting line 202; the pre-cutting line 202 is an easy-to-tear structure with a 30% reduction in thickness to ensure no residue is generated during the peeling process.
[0030] Example 2
[0031] Refer to Figure 4 , on the basis of Example 1, a pull ring 204 is connected to the right side of the pulling strip 202 to enable the nurse to pull the pulling strip 202 more conveniently.
[0032] Example 3
[0033] Refer to Figure 5 , an auxiliary catheter for inserting an enteral nutrition tube, which includes a catheter main body 100 and a connecting part 200. The catheter main body 100 is of a tubular structure, and a connecting groove 101 is formed on the wall of the catheter main body 100. The connecting part 200 is connected into the connecting groove 101, and the connecting part 200 is a zipper mechanism 205.
[0034] Example 4
[0035] Reference Figure 6 Figure 6 , on the basis of Embodiment 3, there is a protective film 206 on the upper side of the zipper mechanism 205. The protective film 206 is connected to the upper part of the inner wall of the connecting groove 101, so as to prevent the hard teeth on the zipper mechanism 205 from contacting the patient's airway and play a role in protecting the patient.
[0036] Although the technical solutions of the present invention have been described and listed in detail, it should be understood that for those skilled in the art, making modifications to the above embodiments or adopting equivalent alternative solutions are obvious to those skilled in the art. These modifications or improvements made without departing from the spirit of the present invention all fall within the scope of protection required by the present invention.
