Description

Technical Field

[0001] The utility model relates to the technical field of gastric lavage tubes, in particular to the technical field of anti-blocking gastric lavage tubes. Background Art

[0002] Gastric lavage refers to the operation of repeatedly injecting a certain amount of liquid into the gastric cavity, mixing it with the gastric contents, and then extracting it. Its purpose is to remove unabsorbed toxins in the stomach or clean the gastric cavity in preparation for clinical gastric surgery. For acute poisoning, such as swallowing organophosphorus, inorganic phosphorus, alkaloids and barbiturates in a short period of time, gastric lavage is an important rescue measure.

[0003] When performing gastric lavage, medical staff usually need to use a gastric lavage tube and a gastric lavage machine. Among them, the gastric lavage tube is usually a single tube with two ends open, such as a gastric lavage tube with announcement number CN2882668Y and a gastric lavage tube with announcement number CN201135638Y, and one end is used to insert into the patient's stomach and the other end is used to connect to the gastric lavage machine to electrically inject the cleaning agent (that is, the liquid in and out of the patient's stomach is achieved through a single tube). However, in actual use, due to the different eating times and food eaten by patients, especially when the eating time is short and the food is difficult to digest, the gastric lavage tube is prone to blockage, which makes it difficult to perform gastric lavage normally. At this time, medical staff have to pull the gastric lavage tube off the gastric lavage machine and then clear the blockage, and sometimes even have to pull the gastric lavage tube out of the patient's stomach. This is not only very troublesome, but may also cause the patient the pain of repeated intubation (which can easily damage the digestive tract mucosa and stomach). Utility Model Content

[0004] The purpose of the utility model is to solve the problems in the prior art and to provide an anti-blocking gastric lavage tube, which can complete the blockage clearing work without pulling the guide tube off the gastric lavage machine.

[0005] To achieve the above-mentioned purpose, the present invention proposes an anti-blocking gastric lavage tube, comprising a guide tube, a joint, a cover and a blockage clearing piece. One end of the guide tube is provided with a plurality of liquid outlets and the other end is branched to form at least two liquid inlets. Each of the liquid inlets is respectively equipped with a joint, and each of the joints is respectively opened and closed by the cover. The blockage clearing piece comprises a guide strip and a picking head. One end of the guide strip is equipped with a picking head and can extend into the guide tube along the tube body channel when the joint is open. The picking head is in the shape of a spiral wire.

[0006] Preferably, the guide tube is transparent, and scale lines are provided on the outer wall of the guide tube.

[0007] Preferably, a bar handle is provided at the other end of the guide bar.

[0008] Preferably, it further includes an auxiliary tube, a spring and a tube body handle, wherein the tube body handle is installed at one end of the auxiliary tube, and the end of the guide bar with the picking head can pass through the auxiliary tube along the tube body channel. The spring is sleeved outside the guide bar and the two ends respectively support the guide bar handle and the tube body handle, and the picking head can be retracted into the tube body channel of the auxiliary tube when the spring is in a natural state and extended out of the tube body channel of the auxiliary tube when the spring is compressed.

[0009] Preferably, both ends of the spring are rotatably connected to the strip handle and the tube handle respectively.

[0010] Preferably, the auxiliary tube is transparent.

[0011] Preferably, the surface of the guide bar is provided with a colored warning layer.

[0012] Beneficial effects of the utility model:

[0013] 1) By providing a branch at the exposed end of the drainage tube to form at least two liquid inlets, it is possible to use the other liquid inlets to inject lubricant into the drainage tube to increase the lubricity of the tube and the obstruction itself without removing the drainage tube from the gastric lavage machine. Furthermore, the other liquid inlets are used to extend the blockage clearing member into the drainage tube to break up the obstruction or wrap the obstruction around its pickup head, allowing the obstruction to be directly sucked out or manually pulled out. The overall structure is simple, easy to manufacture, and convenient to use.

[0014] 2) The blockage clearing device is composed of a guide bar, a pickup head, a bar handle, an auxiliary tube, a spring, and a tube handle. When the spring is compressed, the pickup head extends out of the auxiliary tube to clear the blockage. When the spring is released, the spring's elastic force quickly retracts the pickup head, which is entangled with the blockage, into the auxiliary tube, preventing the blockage from falling back into the guide tube due to friction while the blockage clearing device is being pulled out.

[0015] 3) By setting scale lines on the surface of the transparent guide tube, making the auxiliary tube transparent and the guide strip colored, it is not only convenient to control the insertion depth of the guide tube and to check in real time where the blockage is located in the guide tube, but also convenient to control the insertion depth of the guide strip in real time.
