Description

Technical Field

[0001] The present invention belongs to the technical field of gastric lavage equipment, and more specifically, relates to a gastric lavage device for gastroenterology. Background Art

[0002] For acute poisoning such as swallowing organophosphorus pesticides, inorganic phosphorus, alkaloids, barbiturates, etc., gastric lavage is an extremely important rescue measure. During the use of the gastric lavage device, a mixed drug solution is required for gastric lavage. In actual application, the gastric lavage device usually requires the following technology:

[0003] 1. Gastric lavage machine, which provides power to drive the gastric lavage solution to circulate between the inlet tube, the stomach, and the outlet tube;

[0004] 2. A gastric tube, which is inserted into the patient's stomach and serves as a channel for gastric lavage solution to enter and exit the stomach;

[0005] 3. Liquid inlet and outlet tubes, which transport the gastric lavage solution from the gastric lavage machine to the gastric tube;

[0006] 4. Liquid storage bottle, providing sufficient gastric lavage solution for the gastric lavage process;

[0007] Press the start button of the gastric lavage machine, the gastric lavage machine starts working, and the gastric lavage fluid is injected into the stomach through the liquid inlet tube. When a certain amount of gastric lavage fluid is injected, the gastric lavage machine automatically switches to the liquid discharge state, and the gastric fluid and gastric lavage fluid in the stomach are discharged through the liquid outlet tube. However, the gastric lavage device has the following shortcomings;

[0008] 1. Since the gastric tube is directly inserted into the patient's body, the operator cannot observe the specific condition of the stomach in time. When the amount of liquid is too large or the speed is too fast, it will cause excessive expansion of the stomach and excessive pressure in the stomach. The contents of the stomach and intestines will reflux into the esophagus, increasing the risk of aspiration.

[0009] 2. The gastric lavage tube is divided into an inlet tube and an outlet tube. During gastric lavage, they need to be inserted into the patient's body in turn, which increases the operation time of gastric lavage. Multiple insertions will cause discomfort to the throat and stomach, and the gastric tube is inserted into the patient's stomach without disinfection before use. Improper handling will lead to cross infection. Summary of the Invention

[0010] In order to solve the above technical problems, the present invention provides a gastric lavage device for gastroenterology to solve the above problems.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] In the present invention, the blocking plate is pushed to move along the trajectory of the guide rod. The two guide rods are arc-shaped and symmetrically installed. Under the guidance of the guide rod, the two blocking plates move along the guide rod, and then the two blocking plates slide toward the inside of the guide sleeve. The two blocking plates dock with each other and cooperate with the guide sleeve to block the inside of the first pipe. By controlling the spacing between the two blocking plates, the inlet and outlet volume and speed of the gastric lavage fluid are accurately controlled. The gastric lavage fluid is injected at a uniform speed, which can avoid a sharp increase in gastric pressure, reduce excessive traction and damage to the gastric mucosa, and control the inlet and outlet speed of the gastric lavage fluid to reduce the degree of nausea and vomiting of the patient.

[0016] In the present invention, the pipe at the top is connected to the first pipe, the other end of the first pipe is connected to the pipe body, and multiple liquid outlet pipes are installed inside the pipe body. The liquid outlet pipes are connected to the nozzle to push the gastric lavage fluid into the patient's stomach. By opening multiple liquid collection holes at the top of the pipette, the mixed liquid in the stomach enters the interior of the pipette through the suction force of negative pressure. At the same time, the second pipe is respectively connected to the pipette and the pipette tank, and the mixed liquid in the stomach is sucked into the interior of the pipette tank for storage. The inner pipe and the outer pipe serve as liquid inlet and liquid outlet channels respectively, thereby realizing continuous injection and discharge of gastric lavage fluid, eliminating the need for frequent pipe replacement and saving operation time.

[0017] In the present invention, the tube body is a flexible material, and the tube head is a soft sheath. The first support rod is driven to move by the pipette to stretch one end of the bending plate. The bending plate is forced to bend inward, driving one end of the tube head to shrink. At the same time, the protective cover is also a soft material. Under the bending and squeezing of multiple bending plates, the tube head and the protective cover are both shrunk, making one end of the tube head narrower, which is convenient for better insertion of the tube head. The tube body and the tube head are made of soft materials with suitable diameters to reduce irritation to the patient.

[0018] In the present invention, the mixed liquid impacts the paddles, causing the paddles to drive the rotating shaft to rotate. At the same time, the end of the rotating shaft is connected to the two second support rods through the holder. The second support rods apply a rotational force to the sealing plate, causing the sealing plate to drive the guide rod to rotate. At the same time, the guide rod and the sealing plate rotate synchronously at the side end of the third fixed ring. The mixed liquid is stirred by the rotation of the guide rod and the sealing plate to prevent impurities in the mixed liquid from accumulating and clogging the first pipe and the second pipe.

[0019] In the present invention, the mounting base and the first fixed ring are connected by a pipe inside the mounting base, so that gastric lavage fluid enters the interior of the multiple nozzles, and the gastric lavage fluid is used to flush the patient's stomach. A pressure sensor is installed on the outside of the first fixed ring, and a connecting line is installed inside the mounting base, which are respectively connected to the pressure sensor and the gastric lavage machine body to monitor the intragastric pressure in real time to ensure that the pressure is within a safe range.
