Problems solved by technology

Since the above-mentioned one-way valve is installed in the inner cavity of the liquid storage and directly contacts with the flushing liquid, the material requirements for the one-way valve are relatively high, which not only increases the manufacturing cost of the product, but also brings a large economic burden to the patient, and there are also potential safety hazards.

Embodiment Construction

[0048] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the disclosure as recited in the claims.

[0049] The present invention provides a prefilled catheter flusher. The first embodiment of the prefilled catheter flusher provided by the present invention will be introduced below.

[0050] Such as figure 1 and figure 2 As shown, a prefilled catheter irrigator, the prefilled catheter irrigator includes a liquid storage container 1 that is prefilled with irrigation liquid inside, and the liquid sto...

Abstract

The invention provides a pre-filled catheter flusher. The pre-filled catheter flusher comprises a liquid storage container 1 which is at least partially deformable, wherein the liquid storage container 1 is provided with an injection port 10, and one end of the injection port 10 of the liquid storage container 1 is provided with a pressure applying device 2 capable of closing the injection port 10 from the outside of the liquid storage container 1; when the pressure of the flushing fluid reaches or is more than a preset value due to deformation of the liquid storage container 1, the flushing fluid overcomes the resistance applied to the injection port 10 by the pressure applying device 2 to achieve flushing. According to the pre-filled catheter flusher, the flushing fluid can be prevented from flowing back to the fluid storage inner cavity 11, the pressure applying device 2 does not make contact with the flushing fluid, so that the requirement for materials of the pre-filled catheter flusher is relatively low, the product manufacturing cost is reduced, the product production process is simplified, and use is safe and reliable.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a prefilled catheter flusher for catheter flushing. Background technique [0002] Intravenous catheters are widely used clinically, such as intravenous indwelling needles, PICCs, etc. Tube locking is one of the important links in the successful application of venous catheterization, and tube locking fluid is the key to keep the pipeline unobstructed. As a new type of catheter locking fluid, the prefilled catheter flusher can replace traditional normal saline, heparin diluent and other locking fluids. However, in the pre-filled catheter flusher based on the existing patents, the compressed part of the liquid storage container rebounds, causing the flushing liquid to flow back into the liquid storage cavity, which in turn causes the blood to flow back into the catheter lumen, causing the problem of catheter blockage. In order to solve the above-mentioned problems, the pre...
