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.
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, and work efficiency is low.
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 connecting portion that is detachably connected including one with blood taking needle and with the matched elastic card socket part of vacuum blood collection tube, it is described
Connecting portion is equipped with the jack to match with needle stand, and the internal thread to match with needle stand external screw thread, the connecting portion one are equipped in jack
Side circumferentially, it is axially extending go out several elastic strips, several elastic strips form elastic card socket parts, several elastic strips
One end is fixedly connected with connecting portion, and the other end is free end, and the space surrounded between several elastic strips and connecting portion is formed
Vacuum blood collection tube end grafting cavity volume, the free end one sides of several elastic strips are the insert port of grafting cavity volume, the insertion
The diameter of mouth is less than vacuum blood collection tube end diameter.
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 since the diameter of insert port is less than vacuum blood collection tube end diameter, utilizes the bullet of elastic strip
Property chucking power can prevent from due to the elastic force of elastic rubber sleeve vacuum blood collection pipe end being made to retreat rebound, one-hand operation at this time, separately
One hand can do other preparations, improve efficiency.
The utility model is further described in the following with reference to the drawings and specific embodiments.

Specific embodiment
As shown in Figure 1, 2, anti-rebound needle holder includes a connecting portion 1 being detachably connected with blood taking needle and and vacuum
The matched elastic card socket part 2 of heparin tube, by having certain toughness and the high molecular material of elasticity to be made, on the connecting portion 1
It is equipped with the internal thread to match with needle stand external screw thread equipped with the jack 3 to match with needle stand, in jack 3,1 one side of connecting portion is along circle
Week distribution, it is axially extending go out several elastic strips 201, be usually advisable with being equipped with 3-6 elastic strip 201, several elastic strips 201
Form elastic card socket part 2.Described 201 one end of several elastic strips is fixedly connected with connecting portion 1, and the other end is free end, if described
The space surrounded between dry elasticity item 201 and connecting portion 1 forms vacuum blood collection tube end grafting cavity volume, several elastic strips
201 free end one side is the insert port of grafting cavity volume, and the diameter of the insert port is less than vacuum blood collection tube end diameter.
In this specific embodiment, the connecting portion 1 includes a circular top 101 and circular side wall 102, the side
The internal diameter of wall and 3 end diameter clearance fit of vacuum blood collection tube, several elastic strips 201 are connected on 102 edge of side wall, circle
