Abstract
The utility model is related to a kind of anti-rebound needle holders, the anti-rebound needle holder includes a cylinder, the cylinder generally front end is equipped with top, open rearward end, inner cavity is adapted with vacuum blood collection tube, the top is equipped with the through hole passed through for needle tubing, the through hole is equipped with the internal thread to match with needle stand external screw thread, and circumferentially many places are equipped with to intermediate prominent elastic protrusion part at the cylinder middle part.When the anti-rebound needle holder of the utility model uses, the connection screw thread that two-head blood-taking needle is equipped with by needle stand is connected on anti-rebound needle holder, after two-head blood-taking needle needle tubing pierces through vacuum blood collection tube rubber stopper, the front end of vacuum blood collection tube is inserted into from one end of anti-rebound needle holder insert port, the elastic protrusion part of anti-rebound needle holder cylinder can prevent from due to the elastic force of elastic rubber sleeve vacuum blood collection pipe end being made to retreat rebound by resilient clamping force, one-hand operation at this time, another hand can do other preparations, improve work efficiency.
Description
Technical field
The utility model is related 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 and 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 equipped with to puncture the needle tubing of patient skin, and the other end is equipped with to pierce
The needle tubing of vacuum blood collection tube rubber stopper is worn, one end that needle stand is equipped with the needle tubing for piercing through vacuum blood collection tube rubber stopper is equipped with connection spiral shell
Line.It can repeatedly be taken a blood sample to same case 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 elastic rubber sleeve for sealing on the needle tubing of two-head blood-taking needle, 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,
Both hands of nurse are occupied during this, and operation is very inconvenient, influences work efficiency.
Utility model content
A kind of facilitate nurse the purpose of this utility model is that being provided to overcome the shortage of prior art blood was collected
Anti-rebound needle holder.
To achieve the above object, the utility model provides following technical solution：A kind of anti-rebound needle holder, feature exist
In：The anti-rebound needle holder includes a cylinder, and the cylinder generally front end is equipped with top, open rearward end, inner cavity with it is true
Empty heparin tube is adapted, and the top is equipped with the through hole passed through for needle tubing, and the through hole is equipped with what is matched with needle stand external screw thread
Internal thread, circumferentially many places are equipped with to intermediate prominent elastic protrusion part at the cylinder middle part.
The anti-rebound needle holder of the utility model is in use, the connection screw thread that two-head blood-taking needle is equipped with by needle stand is connected to
On anti-rebound needle holder, after two-head blood-taking needle needle tubing pierces through vacuum blood collection tube rubber stopper, the front end of vacuum blood collection tube is from anti-rebound
One end insertion of needle holder insert port, the elastic protrusion part of anti-rebound needle holder cylinder by resilient clamping force can prevent by
In the elastic force of elastic rubber sleeve vacuum blood collection pipe end is made to retreat rebound, one-hand operation, another hand can do other preparations at this time
Work, improves work efficiency.
The utility model is further described in the following with reference to the drawings and specific embodiments.

Fig. 3 is the specifically used state reference map of the anti-rebound needle holder of the utility model；
Fig. 4 is the specifically used state front view of the anti-rebound needle holder of the utility model；
Fig. 5 is Fig. 4 A-A sectional views.
Specific 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 equipped with top, open rearward end, and by having certain toughness and the high molecular material of elasticity to be made, 1 inner cavity of cylinder is adopted with vacuum
Blood vessel 4 is adapted, and the top is equipped with the through hole 2 passed through for needle tubing, the through hole 2 is equipped with match with needle stand external screw thread in
Screw thread, open rearward end form the insert port of vacuum blood collection tube 4, and circumferentially many places are equipped with to intermediate prominent at 1 middle part of cylinder
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.
There are many realization methods of the elastic protrusion part, can be convex by multiple spherical surfaces being circumferentially disposed on inner wall
It plays composition or the arc bulge loop by circumferentially being set on inner wall is formed.
In this specific embodiment, the elastic protrusion part is made of circumferentially multiple arched elastic items 3, to set 3-6 items
Arched elastic item 3 is advisable, and the present embodiment sets 3 arched elastic items 3 altogether, and arched elastic item 3 is flat strip, is set vertically
Cylinder 1 is put, both ends are separately fixed on 1 inner wall of cylinder, and the distance between both ends are less than 3 length of arched elastic item so that middle part
It arches upward into cylinder 1, the multiple arched elastic item 3 is circumferentially uniformly distributed, and 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.
