Abstract
The present invention relates to the present invention relates to a kind of anti-rebound needle holder, the anti-rebound needle holder includes a cylinder, the cylinder generally front end is provided with top, open rearward end, inner chamber is adapted with vacuum blood collection tube, the top is provided with the through hole passed through for needle tubing, the through hole is provided with the middle part of the internal thread matched with needle stand external screw thread, the cylinder circumferentially many places and is provided with to middle prominent elastic protrusion part.When the anti-rebound needle holder of the present invention is used, the connection screw thread that two-head blood-taking needle is provided with by needle stand is connected on anti-rebound needle holder, two-head blood-taking needle needle tubing is pierced through after vacuum blood collection tube rubber stopper, the front end of vacuum blood collection tube is inserted from one end of anti-rebound needle holder insert port, the elastic protrusion part of anti-rebound needle holder cylinder can be prevented because the elastic force of elastic rubber sleeve makes vacuum blood collection pipe end retreat resilience by resilient clamping force, now one-hand operation, another hand can do other preparations, improve operating efficiency.
Description
Technical field
The present invention relates to a kind of medical apparatus, and in particular to a kind of anti-rebound needle holder for two-head blood-taking needle.
Background technology
Modern medicine needs to carry out blood testing in the diagnosis of many diseases, it has been determined that whether some indexs are exceeded, because
This people can be appreciated that the patients to be assayed such as many often at the chemical examination of hospital, and nurse is also terribly busy.Clinically,
Acquisition mode using two-head blood-taking needle and vacuum blood collection tube as blood of human body sample has been widely applied, two-head blood-taking needle bag
A needle stand for being arranged on middle part is included, one end of needle stand is provided with the needle tubing for being used for puncturing patient skin, and the other end, which is provided with, to be used to pierce
The needle tubing of vacuum blood collection tube rubber stopper is worn, the one end of needle stand provided with the needle tubing for piercing through vacuum blood collection tube rubber stopper is provided with connection spiral shell
Line.Same case can repeatedly be taken a blood sample using two-head blood-taking needle and vacuum blood collection tube.During blood sampling, worn in blood taking needle one end
After entering under patient skin in blood vessel, the other end pierces through vacuum blood collection tube rubber stopper, and blood-sample withdrawal can be arrived using negative pressure of vacuum.But
Due to being arranged with the needle tubing of two-head blood-taking needle for sealed elastic rubber sleeve, blood collection procedure needs to hold vacuum blood collection tube holding
Pressure is applied to it, is sealed using its elasticity, prevents that the elastic force rebound effect due to elastic rubber sleeve from leaking, therefore
Both hands of nurse are occupied during this, operate very inconvenient, influence operating efficiency.
The content of the invention
It is an object of the invention to provide to overcome prior art not enough and a kind of facilitate what nurse taken a blood sample to prevent back
Play needle holder.
To achieve the above object, the invention provides following technical scheme：A kind of anti-rebound needle holder, it is characterised in that：
The anti-rebound needle holder includes a cylinder, and the cylinder generally front end is provided with top, open rearward end, and inner chamber is adopted with vacuum
Blood vessel is adapted, and the top is provided with the through hole passed through for needle tubing, and the through hole is provided with the interior spiral shell matched with needle stand external screw thread
Circumferentially many places are provided with to middle prominent elastic protrusion part in the middle part of line, the cylinder.
The anti-rebound needle holder of the present invention is in use, the connection screw thread that two-head blood-taking needle is provided with by needle stand is connected to and prevented back
Play on needle holder, two-head blood-taking needle needle tubing is pierced through after vacuum blood collection tube rubber stopper, and pin is held in the front end of vacuum blood collection tube from anti-rebound
One end insertion of device insert port, the elastic protrusion part of anti-rebound needle holder cylinder can be prevented due to bullet by resilient clamping force
Property gum cover elastic force vacuum blood collection pipe end is retreated resilience, now one-hand operation, another hand can do other preparations,
Improve operating efficiency.
The invention will be further described with specific embodiment below in conjunction with the accompanying drawings.
Brief description of the drawings

Fig. 2 is the two of specific embodiment of the invention stereoscopic structure sectional view；
Fig. 3 is the anti-rebound specifically used state reference map of needle holder of the invention；
Fig. 4 is the anti-rebound specifically used state front view of needle holder of the invention；
Fig. 5 is Fig. 4 A-A sectional views.
Embodiment
As shown in Figure 1, 2, anti-rebound needle holder described in anti-rebound needle holder includes a cylinder 1, and the cylinder 1 is generally
Front end is provided with top, open rearward end, is made up of the high polymer material with certain toughness and elasticity, the inner chamber of cylinder 1 is adopted with vacuum
Blood vessel 4 is adapted, and the top is provided with the through hole 2 passed through for needle tubing, the through hole 2 is provided with match with needle stand external screw thread in
Screw thread, open rearward end constitutes the insert port of vacuum blood collection tube 4, and circumferentially many places are provided with prominent to centre at the middle part of cylinder 1
Elastic protrusion part, the diameter of circumference is slightly less than the diameter of the block of vacuum blood collection tube 4 where the peak of elastic protrusion part.
The implementation of the elastic protrusion part has a variety of, can be convex by multiple spheres being circumferentially disposed on inwall
The arc bulge loop for constituting or circumferentially setting on inwall is acted to constitute.
In this specific embodiment, the elastic protrusion part is made up of circumferentially multiple arched elastic bars 3, to set 3-6 bars
Arched elastic bar 3 is advisable, and the present embodiment sets 3 arched elastic bars 3 altogether, and arched elastic bar 3 is flat strip, is set vertically
Cylinder 1 is put, two ends are separately fixed on the inwall of cylinder 1, the distance between two ends are less than the length of arched elastic bar 3 so that middle part
Arched upward into cylinder 1, the multiple arched elastic bar 3 is circumferentially uniformly distributed, the circumference residing for peak that middle part is arched upward is straight
Footpath outline is less than the diameter of the block 401 of vacuum blood collection tube 4, while the distance apart from top is preferably slightly larger than the height of block 401
Degree.
