Description

Technical Field

[0001] This utility model belongs to the field of gastric tube auxiliary device technology, and specifically relates to a negative pressure drainage connector for a gastric tube. Background Technology

[0002] In the field of medical care, negative pressure drainage devices are an important medical device widely used in various scenarios that require drainage treatment. They are particularly important in the treatment of gastric tube drainage, which is mainly used to remove accumulated fluid, gas, or digestive residue in the patient's gastrointestinal tract. This is of great significance for maintaining the patency of the patient's digestive tract and preventing complications.

[0003] However, traditional negative pressure drainage devices have significant limitations and operational inconveniences during use. Specifically, due to the design principles and structural limitations of negative pressure drainage devices, their internal capacity is limited, making it impossible to continuously and stably generate negative pressure. To achieve the negative pressure effect, operators need to periodically squeeze the drainage device and then release it to form a cycle of negative pressure-release-re-negative pressure. This operating mode not only increases the workload of nursing staff but may also cause safety hazards due to improper operation.

[0004] More importantly, during drainage of patients with gastric tubes, improper operation when squeezing the negative pressure drainage device can easily allow external air to enter the patient's body through the drainage tube, potentially causing adverse reactions such as abdominal distension and infection, threatening the patient's safety and treatment effectiveness. Therefore, how to effectively prevent air from entering the gastric tube while squeezing the negative pressure drainage device has become an urgent technical challenge to be solved. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by providing a negative pressure drainage connector for a gastric tube.

[0006] The purpose of this utility model can be achieved through the following technical solution: a negative pressure drainage connector for a gastric tube, characterized in that it includes a main tube body and a first tube body and a second tube body respectively disposed on both sides of the main tube body, the end of the first tube body is provided with a first connector for connecting to the gastric tube, the end of the second tube body is provided with a second connector for connecting to the negative pressure drainage connector, a one-way valve is provided on the first tube body, and an exhaust pipe is provided at the bottom of the main tube body.

[0007] The working principle of this utility model is as follows: In use, the first pair of connectors and the second pair of connectors are respectively connected to the gastric tube and the negative pressure drainage device. The one-way valve allows the object to flow only into the first tube. When the negative pressure drainage device is squeezed, the gas squeezed out is blocked by the one-way valve and cannot enter the patient's body from the gastric tube, thus ensuring the patient's safety. Since there is no problem of gas entering the patient's body, and with the setting of the exhaust pipe, the purpose of pressing multiple times can be achieved without removing the negative pressure drainage device, saving time and effort.

[0008] In the aforementioned negative pressure drainage connector for the gastric tube, the exhaust pipe is connected to a storage bag.

[0009] In the aforementioned negative pressure drainage connector for the gastric tube, the upper part of the storage bag is provided with an exhaust hole.

[0010] In the aforementioned negative pressure drainage connector for the gastric tube, an upper convex bag body is provided on one side of the upper part of the storage bag, and an exhaust hole is opened on the upper convex bag body.

[0011] In the aforementioned negative pressure drainage connection for the gastric tube, a one-way valve is provided on the exhaust pipe.

[0012] In the aforementioned negative pressure drainage connector for the gastric tube, a three-way valve is provided between the first connector and the one-way valve. The first connector and the one-way valve are respectively connected to the first port and the second port of the three-way valve. The third port of the three-way valve is used to connect to a syringe to inject drugs into the gastric tube.

[0013] In the aforementioned negative pressure drainage connector for the gastric tube, the third port of the three-way valve is provided with a cap.

[0014] Compared with existing technologies, it has the following advantages:

[0015] 1. By setting a one-way valve that only allows objects to flow into the first tube, external gas is prevented from entering the patient's body through the gastric tube, thus ensuring the patient's safety.

[0016] 2. An exhaust pipe is installed. Pressing the negative pressure drainage device releases gas through the exhaust pipe for energy storage. Due to the one-way valve, there is no need to worry about external gas entering the patient's body when the negative pressure drainage device is storing energy. This solves the technical problem of how to effectively prevent gas from entering the gastric tube while squeezing the negative pressure drainage device. Furthermore, the negative pressure drainage device can be removed to complete repeated energy storage and drainage operations, saving time and effort.

[0017] 3. By setting up a collection bag, the contents of the patient's stomach that are expelled when the negative pressure drainage bag is squeezed and stored are collected, thus avoiding pollution to the outside world. Attached Figure Description

Detailed Implementation

[0021] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0022] like Figs. 1-2 As shown, the negative pressure drainage connector of this gastric tube includes a main tube body 1 and a first tube body 2 and a second tube body 3 respectively disposed on both sides of the main tube body 1. The first tube body 2 is provided with a first connector 4 for connecting to the gastric tube, and the second tube body 3 is provided with a second connector 5 for connecting to the negative pressure drainage connector. A one-way valve 6 is provided on the first tube body 2, and an exhaust pipe 7 is provided at the bottom of the main tube body 1.

[0023] To elaborate further, the exhaust pipe 7 is connected to a collection bag 8; when the negative pressure drainage bag is squeezed to expel gas, some of the objects that were previously drained by the negative pressure will be discharged. Therefore, the exhaust pipe 7 is connected to a collection bag 8 to collect the gas and prevent direct discharge from causing pollution.

[0024] To elaborate further, the storage bag 8 has a vent 9 at the top; the vent 9 can release the gas inside the storage bag 8, preventing the storage bag 8 from bursting due to too much gas and causing damage or even explosion.

[0025] To elaborate further, a raised bag body 10 is provided on one side of the upper part of the storage bag 8, and an exhaust hole 9 is opened on the raised bag body 10. The raised bag body 10 separates the exhaust hole 9 from the main bag body of the storage bag 8, so that when liquid is discharged into the storage bag 8, it will not flow out from the exhaust hole 9.

[0026] To elaborate further, the exhaust pipe 7 is equipped with a one-way valve 2 11; the one-way valve 2 11 only allows objects to flow into the storage bag 8, avoiding back suction on the storage bag 8 during drainage and diverting the suction force of the negative pressure drainer, thus ensuring the negative pressure drainage effect.

[0027] To elaborate further, a three-way valve 12 is provided between the first connector 4 and the one-way valve 6. The first connector 4 and the one-way valve 6 are respectively connected to the first port 13 and the second port 14 of the three-way valve 12. The third port 15 of the three-way valve 12 is used to connect to a syringe to inject drugs into the gastric tube. By rotating the knob of the three-way valve 12, the first port 13 and the third port 15 can be connected, so that drugs can be injected through the syringe to realize the drug feeding function.

[0028] To elaborate further, the third port 15 of the three-way valve 12 is equipped with a cap 16; the cap 16 serves a protective function when no medication is being administered, ensuring the hygiene and cleanliness of the third port 15, and can be removed when administering medication.
