The utility model punctures the needle tube and the needle sleeve sleeved outside it into the chest cavity, and at the same time injects anesthetic drugs through the syringe and the needle tube, and then only needs to pull out the needle tube, and the needle sleeve tube is placed in the chest cavity, and then the drainage tube is connected to the needle tube The effusion can be extracted without the need of anesthesia injection first, and then the puncture is divided into two operations, which reduces the pain of the patient and is easy to operate. After the puncture is in place, a small amount of fluid in the body can be extracted with a syringe first, and whether the puncture position is correct can be judged according to the difference between the fluid and blood, and the position can be adjusted to avoid blind drainage of the fluid.

Description

Negative pressure suction device for pleural enclosed effusion

technical field

The utility model relates to a medical device, in particular to a negative pressure suction device for encased pleural effusion.

Background technique

Encapsulated pleural effusion refers to the adhesion of visceral and parietal pleura in patients with pleurisy, so that the effusion is limited to a certain part of the pleural cavity, and it is more common in the posterior chest wall of the lower chest. Generally, the pleural effusion is extracted repeatedly through a puncture needle, and after the pleural effusion is extracted, anesthesia and other drugs are injected into it. Repeated work, on the one hand, brings inconvenience to the patient, on the other hand, there will be problems during the extraction and injection process. Other gases enter.

Utility model content

The purpose of the utility model is to provide a negative pressure suction device for pleural encased effusion which integrates injection anesthesia and drainage catheter indwelling.

The technical scheme of the utility model is:

A negative pressure suction device for encased pleural effusion, comprising a needle tube and a needle sleeve sleeved on the outside, a bayonet is provided at the end of the needle sleeve, and a needle seat is provided at the end of the needle tube; device and a drainage tube connected to the negative pressure device, the front end of the syringe is connected to the needle holder, and the other end of the drainage tube is connected to the bayonet socket of the needle sleeve.

Preferably, the length of the needle sleeve is shorter than the length of the needle tube, the length of the needle sleeve is 7-13 cm, and the inner diameter is 2 mm.

Preferably, the needle tube is a hollow metal tube, and the front end is in the shape of a needle point.

Preferably, the needle sleeve is engraved with a scale.

Compared with the prior art, the utility model has the advantages of:

(1) The negative pressure suction device for encased pleural effusion provided by this utility model can puncture the needle tube and the needle sleeve sleeve outside it into the chest cavity, and inject anesthetic drugs through the syringe and needle tube at the same time, and then only need to pull out the needle tube, The needle cannula is placed in the thoracic cavity, and then the drainage tube is connected to the needle cannula to extract the effusion. There is no need to inject anesthesia drugs first, and then puncture in two operations, which reduces the pain of the patient and is easy to operate.

(2) After the puncture of the utility model is in place, a small amount of fluid in the body can be extracted with a syringe first, and whether the puncture position is correct can be judged according to the difference between fluid and blood, and the position can be adjusted to avoid blind drainage of fluid.

Below in conjunction with accompanying drawing and embodiment the utility model is further described:

Fig. 1 is the schematic diagram that the negative pressure suction device of thoracic cavity encased effusion described in the present invention is connected with syringe;

Fig. 2 is a schematic diagram of the connection of the drainage tube and the negative pressure device of the negative pressure suction device for encased pleural effusion according to the present invention.

Among them, 1. needle tube; 11. needle seat; 2. needle sleeve; 21. bayonet; 3. syringe; 4. drainage tube; 5. negative pressure device.

Detailed ways

Example:

In order to make it easier for those skilled in the art to understand the technical content of the utility model, the utility model will be further described in detail below in conjunction with the embodiments.

As shown in Figures 1 and 2, the negative pressure suction device for pleural cavity encased effusion disclosed by the utility model includes a needle tube 1 and a needle sleeve 2 set outside it. The length of the needle sleeve 2 is 10 cm, and the inner diameter is 2 mm. , the needle sleeve 2 is also engraved with a scale; the needle tube is a hollow metal tube for storing liquid medicine, and the front end is needle-shaped, extending out of the needle sleeve 2; a bayonet 21 is provided at the end of the needle sleeve, and the A needle seat 11 is arranged at the end of the needle tube.

During the specific operation, as shown in Figure 1, the front end of the syringe 3 containing the anesthetic drug is connected to the needle base 11, and then the needle tube 1 and the needle sleeve 2 are inserted into the chest cavity to a depth of about 3 cm, and anesthesia is performed through the syringe 3 at the same time Drug injection. Then use the syringe 3 to extract a little body fluid, judge whether the puncture position is correct according to the difference between the effusion and blood, and adjust the position if it is not correct, until the effusion extracted by the syringe is the effusion in the pleural cavity, and finally put the syringe 3 together The needle tube 1 is pulled out, and the needle sleeve 2 is left in the chest cavity. As shown in FIG. 2 , the drainage tube 4 is inserted into the bayonet port 21 of the needle cannula, and under the suction of the negative pressure device 6 , the pleural effusion is extracted.

The above-mentioned embodiments are only to illustrate the technical conception and characteristics of the present utility model, and its purpose is to allow people familiar with this technology to understand the content of the present utility model and implement it accordingly, and cannot limit the protection scope of the present utility model. All modifications made according to the spirit of the main technical solutions of the utility model shall fall within the protection scope of the utility model.
