Description

Technical Field

[0001] This utility model relates to the field of medical equipment technology, specifically a gastric tube for gastroenterology. Background Technology

[0002] A gastric tube is a tube inserted directly into the stomach through the patient's nose or mouth. It is mainly used to help patients who cannot swallow to deliver necessary water and food. It can also deliver some special medications that cannot be swallowed through the mouth directly to the stomach. In addition, it can directly extract gastric juice for testing and decompression of the stomach. It is an important treatment measure for patients with dysphagia in the gastroenterology and neurology departments of hospitals.

[0003] Gastric tubes are generally made of polyurethane or silicone. Depending on the material, polyurethane and silicone gastric tubes should be replaced every month. In current technology, because inserting and removing gastric tubes can cause pain to patients, they are only removed when the tube is replaced after insertion. However, food and medication are inevitably introduced into the gastric tube every day, leaving residue on the tube wall. Since the tube is directly connected to the stomach, it only passes through the tube when the patient needs to replenish fluids. The residue is difficult to rinse off completely, resulting in food and medication sedimentation on the tube wall, which can easily lead to blockage. Utility Model Content

[0004] In view of the shortcomings of the prior art, this utility model provides a gastric tube for gastroenterology, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a gastric tube for gastroenterology, comprising: a main tube, a flow control device at the bottom end of the main tube, a ventilation tube and two shunt tubes at the top end of the main tube, and feeding ports at the ends of the two shunt tubes, and a gas control device at the end of the ventilation tube.

[0006] The main tube includes a tube inserted into the stomach through the patient's body. The tube has an inlet tube and an outlet tube arranged side by side inside. The two branch tubes are respectively connected to the inlet tube and the outlet tube. The main tube has a vent hole at the gap between the inlet tube and the outlet tube inside. The main tube also has a flow port for the inlet tube and the outlet tube to pass through.

[0007] The flow control device has an airbag inside, and the inside of the airbag is connected to the air control device through a vent hole and a vent pipe.

[0008] Preferably, the feeding port includes a feeding shell disposed at the end of the diversion tube. The feeding shell is a trapezoidal shell. A soft plastic sheet is integrally disposed on the side of the feeding shell. A pressure cap is disposed at the end of the soft plastic sheet. A plug that is inserted into the feeding shell is disposed on the pressure cap.

[0009] Preferably, the flow inlet is located at the end of the main confluence pipe near the flow control element, and the height of the inner wall of the flow inlet corresponds to the diameter of the inlet pipe.

[0010] Preferably, the flow control device includes an outlet shell disposed at the bottom end of the main confluence pipe, the outlet shell having a pressure-sealing chamber inside, the airbag being located inside the pressure-sealing chamber, and the pressure-sealing chamber having two first constrictions and a corresponding second constriction at both the top and bottom ends, and the two first constrictions being connected to the inlet pipe and the outlet pipe respectively.

[0011] Preferably, the connection points between the first constriction and the inlet pipe and the pressure chamber on both sides are constricted into an arc-shaped transition.

[0012] Preferably, a partition seat is provided at the center of the flow control device, and there are two airbags, with the two airbags respectively installed on both sides of the partition seat.

[0013] Preferably, the air control component includes an air compressor, one end of which is disposed at the end of the air pipe, and the other end of which is integrally provided with a pressure handle. An air compressor plug slides inside the air compressor, and a support rod is provided on one side of the air compressor plug. A pressure plate is provided at the end of the support rod located outside the air compressor. Multiple sets of slots are formed on the side of the support rod, and a locking element is engaged inside the slot. The locking element is disposed on the pressure handle.

[0014] Preferably, the locking component includes a column disposed on the pressure handle, a latch is provided on the side of the column near the top, a baffle is provided on the side of the latch bent at a 90-degree angle, and a buckle groove is provided at the top and bottom of the latch, the inner wall of the buckle groove engaging with the inner wall of the latch groove.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This gastroenterological tube uses a flow control device at one end of the main tube that enters the stomach. An air bladder is added inside the flow control device. When the air bladder inflates, it completely fills the internal space of the flow control device, thus completely blocking the end of the main tube that enters the stomach. A flow port is opened in the main tube near the flow control device to connect the inlet and outlet tubes. This allows warm water to be introduced into the inlet tube in conjunction with the outlet tube after the flow control device is blocked. Because the warm water cannot enter the patient's stomach due to the blockage of the flow control device, the warm water introduced into the inlet tube can flow out through the flow port from the outlet tube, completing the flushing operation of the main tube, reducing the adhesion of residue on the tube wall, and avoiding blockage when food and medication are introduced into the gastroenterological tube.

[0017] 2. This gastrointestinal tube uses an inlet tube and an outlet tube within the main tube. The inlet tube delivers food, water, and medication into the stomach and is solely responsible for intake, while the outlet tube is responsible for expelling rinsing fluid. It can also be used to extract gastric juice or perform gastric decompression. Thus, the inlet and outlet tubes not only give the main tube the ability to rinse but also separate intake and output, preventing gastric juice from being extracted through the inlet tube and leaving residue, which could lead to cross-contamination of food or medication with residual gastric juice when entering the stomach.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-6A gastric tube for gastroenterology includes: a main tube 1, a flow control device 2 at the bottom end of the main tube 1, a ventilation tube 4 and two shunt tubes 3 at the top end of the main tube 1, and feeding ports 5 at the ends of the two shunt tubes 3, and a gas control device 6 at the end of the ventilation tube 4.

[0027] The main tube 1 includes a tube 11 inserted into the stomach through the patient's body. The tube 11 has an inlet tube 12 and an outlet tube 13 arranged side by side. Two branch tubes 3 are connected to the inlet tube 12 and the outlet tube 13 respectively. The main tube 1 has a vent hole 15 at the gap between the inlet tube 12 and the outlet tube 13. The main tube 1 also has a flow port 14 for the inlet tube 12 and the outlet tube 13 to pass through.

[0028] The air control component 2 has an airbag 7 inside, and the airbag 7 is connected to the air control component 6 through a vent 15 and a vent pipe 4.

[0029] The feeding port 5 includes a feeding shell 51 located at the end of the diversion tube 3. The feeding shell 51 is a trapezoidal shell. A soft plastic sheet 52 is integrally provided on the side of the feeding shell 51. A pressure cap 53 is provided at the end of the soft plastic sheet 52. A plug 54 is provided on the pressure cap 53 to be inserted into the feeding shell 51. By providing the feeding port 5, food or medicine can enter the diversion tube 3 through the feeding shell 51, expanding the inlet range at the end of the diversion tube 3 and preventing spillage.

[0030] The flow port 14 is located at the end of the main pipe 1 near the flow control element 2, and the height of the inner wall of the flow port 14 corresponds to the diameter of the inlet pipe 12. After the air bag 7 is used to block the inside of the flow control element 2, the flushing liquid entering the inlet pipe 12 can reach its bottom and then enter the bottom of the outlet pipe 13 through the flow port 14, and then flow out through the outlet pipe 13, thereby maximizing the flushing range in the inlet pipe 12.

[0031] The flow control component 2 includes an outflow shell 21 located at the bottom of the main confluence pipe 1. The outflow shell 21 has a pressure-sealing chamber 22 inside, and the airbag 7 is located inside the pressure-sealing chamber 22. The top and bottom of the pressure-sealing chamber 22 are provided with two first constrictions 23 and corresponding second constrictions 24. The two first constrictions 23 are respectively connected to the inflow pipe 12 and the outflow pipe 13. After the airbag 7 is inflated, the first constrictions 23 and the second constrictions 24 are used to limit the airbag 7, so that the inflated airbag 7 can remain and fill the pressure-sealing chamber 22. Pressure is applied to the first constrictions 23 to achieve the sealing effect and prevent the rinsing fluid from entering the stomach.

[0032] In particular, the connections between the first constriction 23 and the inlet pipe 12 and the pressure-sealing cavity 22 on both sides are constricted into an arc-shaped transition, such as... Figure 3As shown, the transition section that shrinks into an arc shape facilitates the passage of food or medicine through the first constriction 23 and the second constriction 24, preventing obstruction and residue caused by sharp edges.

[0033] The flow control component 2 has a partition seat 8 at its center. There are two airbags 7, and the two airbags 7 are installed on both sides of the partition seat 8. The partition seat 8 is used to position the airbags 7 to avoid the situation where the first constriction 23 and the second constriction 24 cannot be exposed after the airbags 7 are contracted.

[0034] The air control component 6 includes an air compressor 61. One end of the air compressor 61 is located at the end of the air pipe 4, and the other end of the air compressor 61 is integrally provided with a handle 62. An air compressor plug 64 slides inside the air compressor 61. A support rod 65 is provided on one side of the air compressor plug 64. A pressure plate 66 is provided at the end of the support rod 65 located outside the air compressor 61. Multiple sets of slots 67 are opened on the side of the support rod 65. A locking member 63 is engaged inside the slots 67 and is provided on the handle 62. By pressing the pressure plate 66, the air compressor plug 64 will slide inside the air compressor 61, forcing the gas in the air compressor 61 into the airbag 7, causing the airbag 7 to expand. Pulling the pressure plate 66 outward can generate negative pressure inside the air compressor 61, causing the airbag 7 to contract, thereby achieving the effect of controlling the airbag 7.

[0035] The locking component 63 includes a column 631 mounted on the pressure handle 62. A latch 632 is provided on the side of the column 631 near the top. A baffle 633 is provided on the side of the latch 632 at a 90-degree bend. The top and bottom of the latch 632 are provided with a buckle groove 634. The inner wall of the buckle groove 634 engages with the inner wall of the slot 67. After the airbag 7 inflates or contracts to a predetermined degree, by slightly rotating the support rod 65, the slot 67 on the support rod 65 can be locked onto the latch 632. Then, when the airbag is released, the slot 67 on the support rod 65 is directly pressed into the buckle groove 634 due to the air pressure, further tightening the locking component and preventing accidental collisions that could cause the slot 67 to detach from the locking component 63.

[0036] Working principle: When food or medicine is introduced into the patient's stomach through a gastric tube, the liquid to be introduced is directly injected into the feeding port 5 corresponding to the inlet tube 12. Then, the air control device 6 is controlled to cause the air bladder 7 inside the flow control device 2 to contract. The liquid flows into the main confluence tube 1 through the feeding port 5 and the diversion tube 3, and finally passes through the flow control device 2 to reach the patient's stomach.

[0037] When rinsing the gastric tube, the air control device 6 is controlled to inflate the air bladder 7 inside the flow control device 2, allowing the rinsing fluid to flow into the feeding port 5 corresponding to the inlet tube 12. After the rinsing fluid reaches the end of the inlet tube 12 near the flow control device 2, it will pass through the flow port 14 and enter the outlet tube 13, and then flow out from the feeding port 5 corresponding to the outlet tube 13, achieving the effect of rinsing the main tube 1.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
