Abstract
The utility model proposes a kind of positive pressure connectors comprising male end is removably combined with disinfectant cap in male end；It include threaded portion and receiving portion in the inner space of disinfectant cap；The second end of threaded portion is connected to the first end of receiving portion；The diameter of receiving portion is greater than the diameter of threaded portion；Threaded portion is formed in the first end of disinfectant cap, and inner circumferential is formed with the internal screw thread in conjunction with the male end of positive pressure connector；Receiving portion is formed in the second end of disinfectant cap, is used to accommodate cover board and is adsorbed with the sponge of thimerosal；Cover board is used for the second end in sealing thread portion；The diameter of cover board be greater than threaded portion diameter and be less than receiving portion diameter.
Description
Technical field
The utility model relates to a kind of medical instrument more particularly to a kind of positive pressure connectors.
Background technique
For common positive pressure connector as shown in figure 5, one end is internal screw thread, the other end is external screw thread.CN204050664U is mentioned
A kind of positive pressure connector with disinfectant cap out, wherein aseptic cotton is arranged in disinfectant cap, when the connector of external screw thread one end is by disinfectant cap
After covering, disinfection face can carry out disinfection to the end face of positive pressure connector connecting with infusion apparatus, reduce the ring that nurse specially sterilizes
Section.
The defect of this positive pressure connector is that disinfectant cap needs in addition to be individually encapsulated, and encapsulates opening when use；If mentioned
Front opening encapsulates, and the disinfectant (usually hospital's alcohol or Iodophor) on disinfectant cap can volatilize, and does not have disinfection；Using rise
To there is certain inconvenience.
Utility model content
In view of the above problems, the utility model is directed to a kind of positive pressure connector, and disinfectant cap does not need individually to pack, and
Thimerosal therein can be maintained for a long time without volatilizing.
The positive pressure connector of the utility model comprising male end is removably combined with disinfectant cap in male end；
It include threaded portion and receiving portion in the inner space of disinfectant cap；The second end of threaded portion and the first end of receiving portion connect
It is logical；The diameter of receiving portion is greater than the diameter of threaded portion；Threaded portion is formed in the first end of disinfectant cap, and inner circumferential is formed with and positive pressure
The internal screw thread that the male end of connector combines；Receiving portion is formed in the second end of disinfectant cap, is used to accommodate cover board and is adsorbed with
The sponge of thimerosal；Cover board is used for the second end in sealing thread portion；The diameter of cover board is greater than the diameter of threaded portion and is less than and accommodates
The diameter in portion.
Preferably, the disinfectant cap is connected on positive pressure connector by belt.
Preferably, the first end of the belt forms lantern ring, and the set ring set is on the periphery of positive pressure connector.
After the male end of positive pressure connector enters disinfectant cap, male end is compressed cover board top Xiang Haimian, sponge, sponge
Gap of the thimerosal of middle absorption between cover board and receiving portion inner circumferential enters in threaded portion, to the outer spiral shell in threaded portion
Line end carries out disinfection；
After the male end of positive pressure connector exits disinfectant cap, sponge restores to the original state, and pushes cover board to threaded portion, cover closure
The second end of threaded portion.
By the closing of cover board, only when disinfectant cap is screwed in the male end of positive pressure connector, thimerosal just can be from lid
The gap of plate and receiving portion inner circumferential is oozed out；When disinfectant cap is not used, cover board covers threaded portion, separates the company of threaded portion and receiving portion
It is logical, prevent thimerosal to volatilize outward.
Detailed description of the invention
Fig. 1 is that the structural diagrams of the positive pressure connector of the utility model are intended to；
Fig. 2 is the schematic diagram of the section structure of the disinfectant cap of the positive pressure connector of the utility model；
Fig. 3 is the section knot after the disinfectant cap removal cover board of the positive pressure connector of the utility model and the sponge of absorbing disinfection liquid
Structure schematic diagram；
Fig. 4 is schematic diagram of the disinfectant cap of the positive pressure connector of the utility model in conjunction with the male end of positive pressure connector；
Fig. 5 is the schematic diagram of the positive pressure connector of the prior art.
Specific embodiment
In the following, being described in detail in conjunction with positive pressure connector of the attached drawing to the utility model.
The positive pressure connector of the utility model comprising male end 10 is removably combined with disinfection in male end 10
Cap 20.
It include threaded portion 21 and receiving portion 22 in the inner space of disinfectant cap 20；The second end and receiving portion 22 of threaded portion 21
First end connection；The diameter of receiving portion 22 is greater than the diameter of threaded portion 21；Threaded portion 21 is formed in the first end of disinfectant cap,
Inner circumferential is formed with the internal screw thread in conjunction with the male end of positive pressure connector；Receiving portion 22 is formed in the second end of disinfectant cap 20,
Sponge 23 for accommodating cover board 24 He being adsorbed with thimerosal；Cover board 24 is used for the second end in sealing thread portion 21；Cover board 24
Diameter be greater than threaded portion 21 diameter and be less than receiving portion 22 diameter.
Disinfectant cap 20 is connected on positive pressure connector by belt.
The first end of belt forms lantern ring, and the set ring set is on the periphery of positive pressure connector, and thus convenient sterilizing cap rotates.
After the male end of positive pressure connector enters disinfectant cap, male end is compressed cover board top Xiang Haimian, sponge, sponge
Gap of the thimerosal of middle absorption between cover board and receiving portion inner circumferential enters in threaded portion, to the outer spiral shell in threaded portion
Line end carries out disinfection；After the male end of positive pressure connector exits disinfectant cap, sponge restores to the original state, and pushes cover board to threaded portion, covers
The second end in plate sealing thread portion.
