Abstract
The utility model discloses a time blood observation window of puncture ware, including puncture ware nook closing member, the nook closing member passes through the needle file and installs the tip at the pipe seat, another of pipe seat for the tip end cap sealed, connect on the pipe seat lateral wall between end cap and needle file one with the pipe of nook closing member, pipe seat intercommunication, end cap and needle file between the part set up to the transparence, form the observation window, the pipe on be close to the pipe seat the position set up a blister cavity. The utility model discloses an one end blister cavity thick than the pipe that sets up on the pipe returns blood through blood hydraulic pressure force, because the volume of blister cavity is great, and the easier compressed of air that includes to can let the blood in the vein return blood to observation window, and the observation window is the partly of pipe seat, consequently observes more easily.
Description
Technical field
This utility model relates to the blood back observation window of a kind of perforator；Belong to medical device technology neck
Territory.
Background technology
Venous detaining needle is also known as venous catheter needle.The building block of core includes being retained in blood
Soft conduit/sleeve pipe in pipe, and stainless guiding puncture nook closing member.By conduit during use
Puncture into Ink vessel transfusing together with nook closing member, after conduit fully enters blood vessel, withdraw out nook closing member, only
Soft catheter retaining at Ink vessel transfusing thus is carried out infusion treatment.On guiding puncture nook closing member sidewall
Having breach is watch window, in order to allows medical personnel observe whether blood back, thus is used for
It is confirmed whether to prick into vein blood vessel.But owing to guiding puncture nook closing member is very thin, watch window also phase
Should be the most tiny, be not suitable for observing.
Utility model content
The purpose of this utility model is to provide for the blood back observation window of a kind of perforator, to solve
The problems referred to above of prior art.
The purpose of this utility model is achieved through the following technical solutions.
The blood back observation window of a kind of perforator, including perforator nook closing member, described nook closing member passes through needle stand
Being arranged on the one end of catheter block, the other end plug of described catheter block seals, stifled
A conduit connected with nook closing member, catheter block is connected on catheter block sidewall between head and needle stand；Institute
Between plug and the needle stand stated, part is set to transparence, forms observation window, on described conduit
Near the position of catheter block, one blister cavity is set.
It is cased with safety head outside described nook closing member.
This utility model passes through the blister cavity that one end of setting is thick compared with conduit on conduit, passes through
Blood pressure blood back, owing to the volume of blister cavity is relatively big, the air included is easier to be compressed,
It is thus possible to allow the blood blood back in vein to watch window；And observation window is catheter block one
Point, therefore it is easier to observe.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
In figure: 1, nook closing member 2, needle stand 3, catheter block 4, plug 5, conduit 6,
Observation window 7, blister cavity.
Detailed description of the invention
Of the present utility model construction features is expanded on further below in conjunction with the accompanying drawings with specific embodiment.
The blood back observation window of a kind of perforator as shown in Figure 1, including perforator nook closing member 1, institute
State nook closing member 1 and be arranged on the one end of catheter block 3 by needle stand 2, described catheter block 3 another
One end plug 4 seals, and catheter block 3 sidewall between plug 4 and needle stand 2 connects
One conduit 5 connected with nook closing member 1, catheter block 3；Between described plug 4 and needle stand 2
Set up separately and be set to transparence, form observation window 6, near the position of catheter block 3 on described conduit 5
Install a blister cavity 7.
During use, medical personnel open safety head, then puncture as in vein blood vessel, due to quiet
Arteries and veins blood pressure makes blood from nook closing member 1 blood back, owing to the volume of blister cavity 7 is relatively big, the sky included
Gas is easier to be compressed, it is thus possible to allow the blood blood back in vein to observation window 6；And observe
Window 6 is a part for catheter block 3, is therefore easier to observe.
Claims (2)
1. a blood back observation window for perforator, including perforator nook closing member, it is characterised in that:
Described nook closing member is arranged on the one end of catheter block, the other end of described catheter block by needle stand
Seal with plug, connection one and nook closing member, conduit on the catheter block sidewall between plug and needle stand
The conduit of seat connection；Between described plug and needle stand, part is set to transparence, is formed and observes
Window, on described conduit, the position near catheter block arranges a blister cavity.
The blood back observation window of a kind of perforator the most according to claim 1 is characterized in that:
It is cased with safety head outside described nook closing member.
