Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, in particular to a flowering button gastric fistula component, which is a flowering button type indwelling gastric fistula catheter used in gastrostomy surgery. Background Art

[0002] Percutaneous endoscopic gastrostomy (PEG) is a device for enteral nutrition by inserting a gastrostomy tube through an endoscope. It is safe, easy, fast and inexpensive. Compared with nasogastric feeding tubes, it has the advantages of continuous nutritional support, less pain for patients, and is less likely to cause gastroesophageal reflux and aspiration. In addition, the gastrostomy tube is not exposed to the outside, maintaining the patient's appearance and dignity, effectively reducing the patient's psychological burden, and can be left in place for a long time.

[0003] The gastrostomy catheters currently sold on the market are often fixed to the patient's body surface using a fixing plate or medical tape after being placed in the patient's stomach. The front end is fixed by a traditional balloon, which has the risk of balloon bursting. Generally, gastrostomy catheters need to be replaced after 30 days of indwelling, which brings more pain to patients, affects their quality of life, and increases the burden on medical staff. Utility Model Content

[0004] The utility model provides a blooming button gastric fistula assembly, which eliminates the problem of fixing the gastrostomy catheter on the patient's body surface, so that the catheter connection port exposed on the body surface does not need to be specially fixed. The front end blooming design replaces the traditional balloon, has no risk of balloon burst, and can be used for ultra-long-term retention.

[0005] The technical solution adopted is:

[0006] The flower-shaped button gastric fistula assembly comprises a gastric fistula catheter and an indwelling auxiliary tool.

[0007] The gastric fistula catheter comprises a petal portion, a catheter body, a body surface portion and a check valve.

[0008] The lower part of the gastric fistula catheter is a petal part, which includes a plurality of curved pieces, the lower ends of the curved pieces are fixedly connected together, and the upper ends of the curved pieces are fixedly connected together to the lower opening of the catheter body.

[0009] The upper opening of the catheter body is fixedly connected to the body surface.

[0010] A hole is opened on the body surface and a check valve is provided.

[0011] The retention auxiliary tool comprises a main body rod, a connecting rod and a tip end.

[0012] A connecting rod is fixed to the lower end of the main body rod, and a rod-shaped tip end is fixed to the lower end of the connecting rod.

[0013] The indwelling auxiliary tool can be used with catheter bodies of different lengths.

[0014] The main body rod is provided with digital scale.

[0015] A movable ring is arranged on the main body rod.

[0016] The movable ring is in a circular ring shape, and has two movable ring notches opened along the axial direction at the bottom, and a movable ring clamping block is fixed on the inner surface of the movable ring part in the movable ring notch.

[0017] A plurality of slots are arranged on the main body rod along the axial direction.

[0018] There is also a handle slot on the handle portion corresponding to the movable ring, and a front end bayonet portion corresponding to the lower end of the body surface.

[0019] The handle portion and the front end bayonet portion are respectively fixed to the upper end and the lower end of the main body portion of the handle.

[0020] Its advantages are:

[0021] This design adopts an ultra-short design of the catheter body and a tight combination of fixed connection ports, which can fit closely to the patient's body surface without special fixation. The blooming design at the front end replaces the traditional balloon fixation method, which not only avoids the risk of balloon bursting, but also increases the retention time of the catheter. Compared with the 30-day retention of general gastrostomy catheters, this product can be retained for 180 days, reducing the pain of replacing gastric fistula catheters for patients, improving the quality of life of patients, and reducing the burden on medical staff.

[0040] The upper opening of the catheter body 1-3 is fixedly connected to the block-shaped body surface 1-4 with an arc-shaped surface.

[0041] The body surface 1-4 is opened and a connection port 1-8 is fixedly provided, and a check valve 1-7 is provided in the connection port 1-8.

[0042] The top end of the opening of the body surface 1-4 is fixedly installed (by gluing) to fix the connection port 1-9.

[0043] A connecting belt 1-5 is fixed on the body surface portion 1-4, and a cap 1-6 is fixed on the connecting belt 1-5.

[0044] The petal portion 1-1, the insertion support portion 1-2 and the catheter body 1-3 are formed by using a silicone molding integrated forming technology, and then connected with the body surface portion 1-4, the connecting band 1-5 and the cap 1-6 by using a silicone molding technology.

[0045] The indwelling auxiliary tool 2 includes a gripping portion 2-1, a main body rod 2-2, a movable ring 2-3, a digital scale 2-4, a connecting rod 2-5 and a distal end portion 2-6.

[0046] A connecting rod 2-5 is fixed to the lower end of the main body rod 2-2, and a rod-shaped tip portion 2-6 is fixed to the lower end of the connecting rod 2-5.

[0047] There are axial through holes in the main body rod 2-2, the connecting rod 2-5 and the tip end 2-6.

[0048] The two ends of the connecting rod 2-4 are connected to the tip end 2-5 and the main rod 2-2 respectively by means of glue.

[0049] A plate-shaped holding portion 2-1 is fixed to the upper end of the main body rod 2-2, and the holding portion 2-1 and the main body rod 2-2 are integrally injection-molded with silicone.

[0050] The main body rod 2-2 is provided with digital scales 2-4.

[0051] A movable ring 2-3 (plastic) is provided on the main body rod 2-2.

[0052] The movable ring 2-3 is annular, with two movable ring notches 2-3-1 opened along the axial direction at the bottom, and the inner surface of the movable ring 2-3 part in the movable ring notches 2-3-1 is provided with a fixed integrally formed movable ring block 2-3-2.

[0053] A plurality of slots 2-2-1 are provided on the main body rod 2-2 along the axial direction.

[0054] The handle 3 (metal handle) includes a handle portion 3-1, a main body portion 3-2 and a front end bayonet portion 3-3 which are integrally formed into a U-shaped component.

[0055] The upper and lower ends of the long plate-shaped main body 3-2 are respectively fixed with a handle 3-1 and a front end clamping portion 3-3. The handle 3-1 has a handle clamping groove.

[0056] The working principle is:

[0057] The indwelling auxiliary tool 2 can be used in conjunction with catheter bodies 1-3 of different lengths.

[0058] In the actual retention process, firstly, according to the length of the flower-shaped button gastric fistula catheter body 1-3, the movable ring 2-3 can be twisted. Due to its certain elasticity, the movable ring 2-3 part in the movable ring notch 2-3-1 and the movable ring block 2-3-2 can be opened outward a little and moved up and down on the main body rod 2-2 to the position where it needs to be stuck. The movable ring 2-3 is twisted, and the movable ring block 2-3-2 is stuck in the card slot 2-2-1.

[0059] The tip end portion 2-6 passes through the fixed connection port 1-9, the check valve 1-7 and the connection port 1-8, and passes downward from the catheter body 1-3 to the insertion support portion 1-2 of the petal portion 1-1, and the axial hole in the tip end portion 2-6 is buckled on the insertion support portion 1-2.

[0060] The front end bayonet portion 3-3 is clamped to the lower end of the body surface portion 1-4, and the handle portion 3-1 is fixed to the upper part of the movable ring 2-3 which has been adjusted to a good position, so that the multiple curved pieces of the petal portion 1-1 are straightened. At this time, the shape of the petal portion 1-1 is similar to a catheter ( Fig.12 ). Insert the straightened petal portion 1-1 into the pre-created fistula, release the handle 1, pull out the indwelling auxiliary tool 2, and restore the petal portion 1-1 to the blooming shape, and gently pull the catheter body 1-3 to confirm the indwelling position.

[0061] Through the body surface part 1-4, connecting tubes of different specifications can be connected to inject nutrient solution into the stomach through the catheter body 1-3, and the operating fluid flows out from the gap of the petal part 1-1. After the injection is completed, the cap 1-6 is buckled on the fixed connection port 1-9 to seal it.

[0062] The length of the catheter body 1-3 can be ultra-short, for example, 5 cm.
