Problems solved by technology

The problem existing in the existing disinfection cap is that after a long time of use, for example, the next infusion time is the next day, due to the consumption and volatilization of the disinfectant, the disinfection sponge will dry up and can no longer have a good disinfection effect on the infusion joint , the nurse still needs to perform the infusion after manual disinfection again
However, in order to ensure the standardization of aseptic operation, this kind of sterilizer requires professionals to add liquid or replace the sterilizing sponge, which still takes a lot of time, is not easy to use, and the operation effect of different personnel is not consistent enough, resulting in the disinfection effect uncertainty
In addition, since the disinfectant capsule is attached to the top of the cap, mishandling may occur

Embodiment 1

[0024] Such as Figure 1~3 As shown, an indwelling needle connector disinfection cap includes a cylindrical cap body 1, and the openings at both ends of the cap body 1 respectively form a disinfection cap mouth 1d and a disinfectant liquid outlet. The cap body 1 is provided with a disinfectant solution carrier 2 . The mouth of the disinfection cap 1d is sealed and covered with a sealing sticker 5 .

[0025] Said disinfectant liquid mouth cover of said cap body 1 is provided with extruding sleeve 3, and said extruding sleeve 3 is connected with the outer wall of said cap body 1 sealingly to form a closed extruding sleeve lumen, and said extruding sleeve lumen is Connected with the disinfectant through the mouth, the extrusion sleeve 3 has both rigidity and elasticity, which can not only maintain the shape of its inner cavity in a free state and withstand a certain extrusion force, but also deform when subjected to a large extrusion force So that its inner cavity is flattened ...

Embodiment 2

[0040] The disinfection cap structure of this embodiment is similar to Example 1, the difference is that, as Figure 4 In this embodiment, the cap body 1 is hollow cylindrical, and one end of the cap body 1 is open to form a disinfection cap opening 1d, and the center of the other end end plate 1g of the cap body 1 is provided with a disinfectant solution opening. The side is gradually inclined towards the direction of the mouth of the disinfection cap 1d from its edge to the mouth of the disinfectant to form a diversion surface 8 . The outer surface of the end plate 1g of the cap body 1 is vertically provided with a hidden twist handle 1a, and a liquid storage rod is arranged between the hidden twist handle 1a and the end plate of the cap body 1 .

[0041] An internal thread 1c is processed on the inner wall of the cap body 1 close to the disinfection cap opening 1d for sealing connection with the infusion connector with external thread.

Embodiment 3

[0043] The disinfection cap structure of this embodiment is similar to Example 1, the difference is that, as Figure 5 , The middle section of the operating twist handle 1a is integrally formed with a pressing plate 1e, and the pressing plate 1e and the cap body 1 have the same center line. The purpose of setting the pressing plate 1e is to put the cap body 1 on the infusion joint when installing the disinfection cap on the infusion joint, and then push the pressing plate 1e by hand to facilitate the installation of the cap body 1 in place.

[0044] In this embodiment, the installation method between the extrusion sleeve 3 and the cap body 1 is different from that in Embodiment 1: as Figure 6 , The middle part of the outer wall of the cap body 1 is integrally formed with a mounting ring 1f. The extrusion sleeve 3 is in the shape of a hollow cylinder with one end open, and the extrusion sleeve 3 is set outside the end where the disinfectant solution of the cap body 1 is passe...

Abstract

The invention discloses indwelling needle connector disinfection cap. The indwelling needle connector disinfection cap comprises a cap body, wherein a disinfectant carrier is arranged in the cap body, the cap body is provided with a disinfection cap opening and a disinfectant passing opening, the disinfection cap opening is covered with a sealing paste in a sealed mode, a deformable liquid storage piece is arranged corresponding to the disinfectant passing opening, and the liquid storage piece is separated from the disinfectant carrier. An extrusion sleeve covers the disinfectant passing opening, the extrusion sleeve is connected with the outer wall of the cap body in a sealed mode to form a closed extrusion sleeve inner cavity, the extrusion sleeve inner cavity communicates with the disinfectant passing opening, the liquid storage piece is arranged in the extrusion sleeve inner cavity, and when the extrusion sleeve is pressed to enable the liquid storage piece to be extruded, the disinfectant stored in the liquid storage piece flows to the disinfectant carrier through the disinfectant passing opening. The disinfection cap has the advantages that in the process of mounting and removing the disinfection cap, the disinfectant is discharged to the disinfectant carrier by pinching and pressing the extrusion sleeve, disinfection treatment on the infusion connector can be achieved, convenience and rapidness are achieved, and secondary disinfection is synchronously achieved when the disinfection cap is removed.

Description

technical field [0001] The invention belongs to the technical field of medical transfusion pipeline fittings, and in particular relates to a disinfection cap for an indwelling needle joint. Background technique [0002] Clinically, medical infusion lines are used to establish drug delivery pathways for patients. The single-use infusion tube is removed after the infusion is completed, and for patients who need multiple infusions over time or consecutive days, intravenous indwelling needles are generally used. In addition, central venous catheters are widely used for some patients who need to establish a large venous rapid fluid channel. The catheter or central venous catheter will remain in place for a period of time after it is inserted into the vein. After each infusion is completed, the infusion connector needs to be sealed, and the connector must be strictly sterilized during the next infusion, which is a part of the clinical aseptic operation procedure. At present, nu...
