Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a gastrointestinal decompression device for gastrointestinal nursing. Background Technology

[0002] A gastrointestinal decompression device is a common medical device in gastroenterology. It uses the principles of negative pressure suction and siphon to insert a gastric tube through the mouth or nose, and then suction out the gas and liquid accumulated in the gastrointestinal tract. For patients with gastrointestinal obstruction, it can reduce the pressure and distension in the gastrointestinal tract. For patients with gastrointestinal perforation, it can prevent the contents of the gastrointestinal tract from continuing to leak into the abdominal cavity through the perforation, and it is also beneficial to the healing of the anastomosis after gastrointestinal anastomosis.

[0003] Based on a search for gastrointestinal decompression devices, a Chinese utility model patent was found, with authorization announcement number CN220877386U. This patent discloses a gastrointestinal decompression device that uses a breathable and waterproof membrane to separate gas and liquid. Gas is discharged from the exhaust port, but liquid remains inside the device. In actual use, there is a possibility that a large amount of liquid may require replacement of the liquid storage container within the device, leading to interruption of decompression and inconvenience in replacement. While the device uses an elastic ring to achieve a squeezing effect and solve the blockage problem, this method can easily cause nausea and discomfort for patients and needs improvement.

[0004] Based on the above, this utility model proposes a gastrointestinal decompression device for gastrointestinal nursing. Utility Model Content

[0005] To address the problems mentioned in the background above, this utility model provides a gastrointestinal decompression device for gastrointestinal nursing.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows.

[0007] A gastrointestinal decompression device for gastrointestinal nursing includes a gastric tube, a negative pressure tube, and two reservoir bottles. One end of the gastric tube is equipped with an anti-blockage connector, and the other end is connected to the two reservoir bottles through a first three-way tube. The two reservoir bottles are connected to the negative pressure tube through a second three-way tube, and a negative pressure pump is installed at the end of the negative pressure tube.

[0008] Furthermore, the anti-clogging connector includes a thick tube and a thin tube. The opening of the thick tube is connected to the gastric tube. A connection hole is coaxially opened at the closed end of the thick tube. The opening of the connection hole is connected to the opening of the thin tube. Several first through holes are arrayed at the closed end of the thin tube. Ribs are arranged between the thick tube and the thin tube. The interior of the ribs is hollow and communicates with the thick tube or the thin tube. The side of the ribs away from the thin tube is set as an inclined surface. The distance between the inclined surface and the thin tube decreases along the axis of the thick tube and from the opening of the thin tube to the closed end of the thin tube. Several ribs are arrayed along the circumference of the thin tube. Several second through holes are arrayed on the outer circular surface of the thin tube. Several fourth through holes are arrayed on the outer surface of the ribs. Several third through holes are arrayed at the closed end of the thick tube.

[0009] Furthermore, the gastric tube is externally fitted with a nasal plug and a mouth plug, with the nasal plug located on the side of the mouth plug facing the anti-blocking connector.

[0010] Furthermore, one end of the first three-way tube is connected to the gastric tube, and the remaining two ends of the first three-way tube are each equipped with a first branch tube, which are connected to two storage bottles respectively.

[0011] Furthermore, one port of the second three-way pipe is connected to the negative pressure pipe, and the remaining two ports of the second three-way pipe are each equipped with a second branch pipe. The two second branch pipes are respectively connected to two liquid storage bottles, and both the first branch pipe and the second branch pipe are equipped with solenoid valves.

[0012] Furthermore, the liquid storage bottle includes a bottle body, and a bottle cap is detachably installed at the bottle mouth. The outer circular surface of the bottle cap is provided with an inlet and an outlet. The inlet is connected to a first branch pipe, and the outlet is connected to a second branch pipe.

[0013] Furthermore, a water level sensor is installed inside the bottle.

[0014] Furthermore, an L-tube is provided at the inlet opening inside the bottle cap. The end of the L-tube is coaxial with the bottle cap. The bottle mouth is shaped like a frustum and the diameter of the bottle mouth decreases along the axis of the bottle body from the bottom to the mouth.

[0015] Compared with the prior art, the advantages of this utility model are as follows:

[0016] When in use, the gastric tube is inserted into the patient's body and fixed by the nasal plug or mouth plug. When aspirating liquids and gases, the liquids, gases and fluids can all enter the gastric tube through the holes under negative pressure. Food residue in the patient's stomach and intestines is blocked by the ribs, so it is impossible to block all the holes. Therefore, it can play a role in preventing blockage during gastrointestinal decompression.

[0017] When in use, alternating between the two storage bottles ensures that the gastrointestinal decompression process is not interrupted. Attached Figure Description

[0025] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0026] Reference Figures 1-5 A gastrointestinal decompression device for gastrointestinal nursing includes a gastric tube 2, a negative pressure tube 10, and two reservoirs 7, wherein:

[0027] One end of the gastric tube 2 is equipped with an anti-blockage connector 1. Further details can be found by referring to... Figure 2 and Figure 3The anti-clogging connector 1 includes a thick tube 101 and a thin tube 102. The opening of the thick tube 101 is connected to the gastric tube 2. A connection hole is coaxially formed at the closed end of the thick tube 101, and the opening of the connection hole is connected to the opening of the thin tube 102. A plurality of first through holes 104 are arrayed at the closed end of the thin tube 102. A rib 103 is provided between the thick tube 101 and the thin tube 102. The rib 103 is hollow inside and communicates with either the thick tube 101 or the thin tube 102. The side of the rib 103 away from the thin tube 102 is set as an inclined surface. The distance between the inclined surface and the thin tube 102 decreases along the axis of the thick tube 101 and from the opening of the thin tube 102 towards the closed end of the thin tube 102. The thin tube 102 has several circumferentially arranged through holes, and its outer circular surface has several second through holes 105. The outer surface of the rib 103 has several fourth through holes 107, and the closed end of the thick tube 101 has several third through holes 106. The significance of this is that, during use, when the gastric tube 2 is inserted into the patient's body and liquids and gases are aspirated, the liquids, gases, and fluids can all enter the gastric tube 2 through the through holes under negative pressure. Food residue in the patient's stomach and intestines is blocked by the rib 103, making it impossible for all through holes to be blocked. Therefore, it can play a role in preventing blockage during gastrointestinal decompression. It should be noted that only a portion of the through holes are shown in the figure.

[0028] The gastric tube 2 is externally equipped with a nasal plug 3 and a mouth plug 4. The nasal plug 3 is located on the side of the mouth plug 4 facing the anti-blocking connector 1. Its purpose is that when the gastric tube 2 is inserted into the patient's nasal cavity, it is inserted into the nose through the nasal plug 3 to fix the gastric tube 2. When the gastric tube 2 is inserted into the patient's mouth, the patient bites on the mouth plug 4 to fix the gastric tube 2. At the same time, it prevents the patient from unconsciously closing the gastric tube 2 when the mouth is open for a long time, thus preventing it from being crushed and interfering with the gastrointestinal decompression process.

[0029] The other end of the gastric tube 2 is connected to two liquid storage bottles 7 via a first three-way tube 5. Furthermore, one end of the first three-way tube 5 is connected to the gastric tube 2, and the remaining two ends of the first three-way tube 5 are each provided with a first branch tube 6, which are respectively connected to the two liquid storage bottles 7.

[0030] The two liquid storage bottles 7 are connected to the negative pressure pipe 10 through the second three-way pipe 9. Furthermore, one end of the second three-way pipe 9 is connected to the negative pressure pipe 10, and the remaining two ends of the second three-way pipe 9 are each provided with a second branch pipe 8. The two second branch pipes 8 are respectively connected to the two liquid storage bottles 7. The end of the negative pressure pipe 10 is connected to a negative pressure source, such as a negative pressure pump.

[0031] Solenoid valves are installed on both the first branch pipe 6 and the second branch pipe 8.

[0032] Preferred embodiments, refer to Figure 4The liquid storage bottle 7 includes a bottle body 701, and the bottle body 701 has a bottle cap 702 that can be detachably installed at the bottle mouth, such as by threaded connection, snap-fit ​​or other existing technologies.

[0033] The outer circular surface of the bottle cap 702 is provided with an inlet 703 and an outlet 704. The inlet 703 is connected to the first branch pipe 6, and the outlet 704 is connected to the second branch pipe 8.

[0034] The working principle of this utility model:

[0035] Insert the gastric tube 2 into the patient's stomach and intestines, and fix the gastric tube 2 through the nasal plug 3 or the oral plug 4;

[0036] The two liquid storage bottles 7 are named Liquid Storage Bottle 1 and Liquid Storage Bottle 2 respectively. Through the cooperation of four solenoid valves, the gastric tube 2 and the negative pressure tube 10 can be connected to Liquid Storage Bottle 1 or Liquid Storage Bottle 2. Initially, they are connected to Liquid Storage Bottle 1.

[0037] When the negative pressure pump is activated, it draws liquid and gas into the first storage bottle. The liquid remains in the first storage bottle, while the gas is drawn out by the negative pressure pump. The storage bottle 7 is equipped with a water level sensor. When the liquid level in the first storage bottle reaches a preset value, the sensor sends a signal to connect the gastric tube 2, the negative pressure tube 10, and the second storage bottle. The liquid is stored in the second storage bottle. At the same time, medical staff can disassemble the body of the first storage bottle to drain the liquid and then reassemble it. In this way, the two storage bottles 7 are used alternately to ensure that the gastrointestinal decompression process is not interrupted.

[0038] In a preferred embodiment, an L-tube 705 located inside the bottle cap 702 is provided at the opening of the inlet 703. The end of the L-tube 705 is coaxial with the bottle cap 702. The bottle mouth of the bottle body 701 is shaped like a frustum, and the diameter of the bottle mouth decreases along the axis of the bottle body 701 from the bottom to the mouth. The significance is that liquid can enter the bottle body 701 through the L-tube 705. At the same time, the frustum-shaped bottle mouth can prevent the liquid inside from sloshing out when the bottle body 701 is moved.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
