Abstract

The utility model provides a set up plasma virus inactivation bag puncture syringe needle of safe protection pole, syringe needle on the virus inactivation bag can be pegged graft as an organic whole, take the handle front end both sides of hose with plasma bag tube head and be equipped with the puncture safety protection pole of preventing that corresponds, and the sheath middle part of syringe needle periphery is equipped with the kicking block of outside extension, and the corresponding puncture safety protection pole outer end that prevents that sets up in handle front end both sides is the arc head. When the puncture-proof safety protection rod is used, when the needle head is connected with the connector head on the plasma bag in an inserting mode, the puncture-proof safety protection rods on the two sides of the operating handle play a role in protection, the phenomenon that fingers are punctured accidentally can be avoided, and meanwhile, the protective sleeve on the needle head can be easily pushed open by one hand through the ejector block to use the needle head.

Description

Plasma virus inactivation bag puncture needle head with safety protection rod

Technical Field

The utility model relates to a puncture needle head, specific plasma virus inactivation bag puncture needle head who sets up safe guard bar that says so.

Background

Blood after donation of a blood donor is separated into red blood cells and plasma, after the plasma is filled into a plasma bag, virus inactivation treatment is carried out on the internally filled plasma, the traditional method is that after a needle head on a plasma virus inactivation bag is spliced and communicated with a connector head on the plasma bag, the plasma flows into the virus inactivation bag and is fully mixed with virus inactivated substances, virus inactivation treatment is carried out, when the needle head on the virus inactivation bag is spliced and connected with the connector head of the plasma bag, the phenomenon that fingers are accidentally punctured during puncture often occurs, occupational exposure is caused, diseases transmitted through blood are easily infected, meanwhile, a sheath is arranged on the periphery of the needle head, when puncture is carried out, the sheath is firstly taken down, but because the sheath is tightly connected with the needle head, the sheath is taken down, and the operation is carried out by two hands, which seems to be simple, because an operator is busy, the phenomenon that only one-hand operation can often occur, and the sleeve is not convenient to be taken by one hand.

Disclosure of Invention

An object of the utility model is to solve the above-mentioned realistic problem who exists, provide a plasma virus inactivation bag puncture needle head who sets up safe guard bar, it is both safe and convenient when can letting the syringe needle use.

The utility model discloses a syringe needle and the hose of connecting operation handle as an organic whole and operation handle tail-end connection, the syringe needle has the sheath, and the technical scheme who adopts lies in: the syringe needle on the virus inactivation bag can be pegged graft as an organic whole with the plasma bag tube head, the handle front end both sides of taking the hose are equipped with the safety guard bar of preventing stinging that corresponds, and the sheath middle part of syringe needle periphery is equipped with the kicking block of outside extension, and the safety guard bar outer end of preventing stinging that the handle front end both sides correspond to set up is the arc head.

In the above technical scheme: the puncture-proof safety protection rods correspondingly arranged on the two sides of the operating handle are as long as the needle head.

The utility model has the following advantages and effects: when the syringe needle that constitutes from this uses, the accessible handle both sides correspond the safe guard bar of preventing stinging that sets up, when the syringe needle on the virus inactivation bag pierces the connector tube head on the plasma bag and pegs graft, can let two prevent that stinging safe guard bar side by side gets into the both sides of connector tube head simultaneously, make the syringe needle location puncture and can not accidentally pierce through the lateral wall wounded hand of connecting pipe, and simultaneously, because the sheath has the kicking block, when can letting the cover of getting, can singlehanded finger is backed down the sheath and is used the syringe needle, the problem of unfavorable safe operation and inconvenient operation that appears when having solved from this when current syringe needle and virus inactivation bag are inserted and are linked, the design science, favourable safety and convenient operation.

Drawings

The present invention will be described in detail with reference to the accompanying drawings and examples.

FIG. 1 is a schematic structural view of the present invention,

figure 2 is a schematic top view of the present invention,

FIG. 3 is a schematic view of the sheath structure of the present invention

Detailed Description

Fig. 1, 2 and 3 show: syringe needle 1 on the virus inactivation bag can be as an organic whole with the grafting of plasma bag tube head, 2 front end both sides of handle of taking hose 3 are equipped with the safe guard bar 4 of preventing stinging that corresponds, and 6 middle parts of the sheath of syringe needle 1 periphery are equipped with the kicking block 7 of outside extension, and the safe guard bar 4 outer end of preventing stinging that the corresponding setting in 2 front end both sides of handle is the arc head 5. The puncture-proof safety protection rods 4 correspondingly arranged at the two sides of the operating handle 2 are as long as the needle head 1.

When in use, the puncture-proof safety protection rods 4 can be directly inserted into the two outer sides of the tube head of the connecting tube on the plasma bag due to the arrangement of the corresponding two puncture-proof safety protection rods, so that the needle can vertically puncture the connecting tube head.

Claims (2)

1. The utility model provides a set up blood plasma virus inactivation bag puncture needle head of safe protection pole, includes syringe needle (1) and connects handle (2) and handle (2) tail end connection's hose (3) as an organic whole, syringe needle (1) has sheath (6), its characterized in that: the syringe needle (1) on the virus inactivation bag can be inserted with the plasma bag tube head as an organic whole, the front end both sides of the operation handle (2) of taking hose (3) are equipped with the safe protective rod of protection against thorns (4) that correspond, and the sheath (6) middle part of syringe needle (1) periphery is equipped with kicking block (7) of outside extension, and the safe protective rod of protection against thorns (4) outer end that the correspondence of operation handle (2) front end both sides set up is arc head (5).

2. The plasma virus inactivation bag puncture needle provided with the safety protection rod as claimed in claim 1, wherein: the puncture-proof safety protection rods (4) correspondingly arranged on the two sides of the operating handle (2) are as long as the needle head (1).
