Description

A disposable indwelling needle sealing device with sealing liquid

Technical field:

The utility model relates to a disposable indwelling needle tube sealing device with a tube sealing liquid, which belongs to a medical device, in particular to a clinical medical device for transfusion.

Background technique:

At present, clinically, if a patient needs to indwell an indwelling needle after transfusion, when the indwelling needle is sealed, the indwelling needle needs to be pushed and injected with a lock solution. The tube lock solution needs to be prepared and packed in a sealed container. When in use, the tube lock solution needs to be drawn out with a needle, and then pushed into the indwelling needle. The problems that exist in this way are: 1. There are many processes for preparing the lock solution, which increases the labor intensity of medical personnel and the risk of secondary pollution; Risk of secondary pollution.

Invention content:

The problem to be solved by the utility model is to provide a disposable indwelling needle tube sealing device which is easy to use and effectively reduces secondary pollution in view of the above deficiencies. Its technical scheme is as follows:

It comprises a soft tube, the outlet of the soft tube is connected with a nipple, an anti-suckback plug is arranged at the bottom of the soft tube, and the outer diameter of the nipple matches the outer diameter of ordinary disposable scalp needles and needle connectors.

Compared with the prior art, the utility model has the beneficial effects of:

1. The main part of the device is a soft tube, which directly squeezes the tube sealing liquid into the indwelling needle through the needle, and does not need to be drawn out with an empty needle for re-injection, which reduces the work process, is easy to use, and can effectively reduce secondary pollution during operation;

2. There is an anti-suckback plug at the bottom of the soft tube. When squeezing the sealing liquid, the anti-suckback plug can be squeezed forward and embedded in the nipple. It cannot be pulled out and is non-reusable;

3. The anti-suck back plug will also prevent suck back and avoid blood backflow;

4. After using the device, it is unnecessary to use a disposable syringe, which saves the cost of the disposable syringe.

Description of drawings:

Fig. 1 is a structural representation of the utility model.

Detailed ways:

Referring to Fig. 1, the utility model comprises a soft tube 2, the outlet of the soft tube 2 is connected with a nipple 3, and the nipple 3 is sealed by a sealing cover 4, and an anti-suckback plug 1 is arranged at the bottom of the soft tube 2, and the soft tube 2 is filled with a seal tube liquid.

When in use, unscrew the sealing cap 4, insert the nipple 3 connecting needle or scalp needle of the flexible tube 2 into the indwelling needle, squeeze the sealing liquid into the indwelling needle, and squeeze the anti-backup plug 1 forward when squeezing the sealing liquid , embedded in the nipple 3 . The outer diameter of the nipple needs to match the outer diameter of the ordinary disposable scalp needle and the needle connector, so that the nipple can be tightly connected with the ordinary disposable scalp needle and the needle connector.

The device can also be widely used as a package for liquid injections. When in use, the needle tube does not need to be pulled out and pushed, but can be connected with the needle and directly squeezed.
