Description

A kind of gastrointestinal blood clot extraction tube

technical field

The invention relates to the technical field of medical devices, in particular to a gastrointestinal blood clot extraction tube.

Background technique

A gastroscopy is a medical examination in which a thin, flexible tube is inserted into the stomach, allowing doctors to directly observe lesions in the esophagus, stomach and duodenum, especially for tiny lesions. Gastroscopy can directly observe the real situation of the inspected part, and can further confirm the diagnosis through pathological biopsy and cytological examination of suspicious lesions. It is the first choice for upper gastrointestinal lesions. Upper gastrointestinal bleeding is a common disease in clinical medicine, including upper gastrointestinal surgery, pancreaticoduodenal surgery, anastomotic bleeding and stress ulcer bleeding, all of which are acute and serious. There is a risk of death if handled. Patients with upper gastrointestinal bleeding, often because of the accumulation of blood and blood clots in the stomach, it is difficult to see the lesions and bleeding sites during gastroscopy. The aperture of the commonly used gastroscope biopsy channel is limited, so it is difficult to quickly and effectively attract, especially blood clots, gastroscopy As soon as it is sucked, it is blocked, the vision is quickly blurred, and the channel is easily blocked. It is necessary to repeatedly remove the gastroscope to clean the inner channel, so the treatment time is delayed.

SUMMARY OF THE INVENTION

Based on this, in view of the above problems, it is necessary to propose a gastrointestinal blood clot extraction tube.

The technical scheme of the present invention is: a gastrointestinal blood clot extraction tube, comprising a drainage pipeline and a negative pressure regulating pipeline arranged on the drainage pipeline, one end of the drainage pipeline is provided with a drainage opening, and the other end is provided with a negative pressure The joint, the drainage opening is in the shape of "Z", the large end of the opening is away from the drainage pipe, the end of the open end of the drainage opening is rounded, and the connection between the drainage opening and the drainage pipe is smooth In transition, an extension edge extending outward is provided at the port of one end of the negative pressure regulating pipe away from the drainage pipe.

When in use, one end of the drainage opening is inserted into the patient's body, the end with the negative pressure connector is connected to the negative pressure system in the hospital, and the drainage opening is set to a "Z" shape, and the larger end of the opening is far away from the drainage pipeline for convenience. The blood clots in the patient's body are sucked into the drainage pipe and discharged through the negative pressure system. At the same time, the medical staff can block the opening of the negative pressure regulating pipe with their hands to facilitate the negative pressure to absorb the blood clots, and block the negative pressure with the fingers to facilitate medical treatment. Personnel can perceive the magnitude of negative pressure during operation, which is convenient for adjustment.

Preferably, the distance between the negative pressure regulating pipe and the drainage opening is 65CM-80CM.

The purpose of setting the negative pressure regulating pipe at 65CM-80CM from the drainage opening is to reserve enough length to avoid the situation that the length of the drainage pipe is not enough during use.

Preferably, a plurality of connecting pieces are evenly distributed on the drainage pipe, and the connecting pieces are provided with a bayonet which is matched with the gastroscope pipe.

The purpose of evenly distributing connecting pieces on the drainage pipe is to facilitate the relative fixing of the drainage pipe and the gastroscope pipe, so that the gastroscope can drive the drainage pipe to move together during intragastric operation.

Preferably, a blocking block is connected to the negative pressure regulating pipeline through a connecting rope.

The purpose of setting the block on the negative pressure regulating pipe is to completely block the opening of the negative pressure regulating pipe when the maximum negative pressure value is required.

The beneficial effects of the present invention are:

1. When in use, extend one end of the drainage opening into the patient's body, connect the end with the negative pressure connector to the negative pressure system in the hospital, and set the drainage opening into a "︺" shape, with the larger end away from the drainage. The pipeline is convenient for sucking the blood clots in the patient's body into the drainage pipeline and discharging through the negative pressure system. At the same time, the medical staff can block the opening of the negative pressure regulating pipeline with their hands to facilitate the negative pressure to suck the blood clots away. It is convenient for medical staff to perceive the size of negative pressure during operation, and it is convenient to adjust.

2. The purpose of setting the negative pressure regulating pipe at 65CM-80CM from the drainage opening is to reserve enough length to avoid the situation that the length of the drainage pipe is not enough during use.

3. The purpose of evenly distributing connecting pieces on the drainage pipe is to facilitate the fixing of the drainage pipe and the gastroscope pipe, so that the gastroscope can drive the drainage pipe to move together during intragastric operation.

4. The purpose of setting the block on the negative pressure regulating pipe is to completely block the opening of the negative pressure regulating pipe when the maximum negative pressure value is required.

Detailed ways

The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Example:

As shown in FIG. 1, a gastrointestinal blood clot extraction tube includes a drainage pipeline 1 and a negative pressure regulating pipeline 2 arranged on the drainage pipeline 1. One end of the drainage pipeline 1 is provided with a drainage opening 3, and the other end is provided with a drainage opening 3. A negative pressure joint 4 is provided, the drainage opening 3 is in the shape of "Z", and the large end of its opening is away from the drainage pipe 1. The end of the open end of the drainage opening 3 is inverted with a rounded corner 5. 3. The connection with the drainage pipe is a smooth transition, and the port of one end of the negative pressure regulating pipe 2 away from the drainage pipe 1 is provided with an extension edge 6 extending outward.
