Description
Technical field
The utility model belongs to blood-taking device technical field more particularly to a kind of blood taking needle from strap retainer.
Background technique
Disposable blood taking needle is during medical inspection for acquiring the important equipment of blood sample, the base of existing blood taking needle
This structure is: including bottle cork needle and its protective case, blood collection needles and its protective case, hose, one end and the bottle stopper of hose are worn
Pricker is connected, and the other end of hose is connected with blood collection needles, and blood collection needles further include needle section and wing plate portion.
Existing disposable blood taking needle has directly begun to blood sampling, syringe needle is not after needle section punctures into human vein
There is fixation, if unlocked needle handle, needle handle shake outside when blood sampling, will increase the pain of patient, and increase puncture failure
Risk, and nurse clinically acquires slightly careless when vein blood specimen, will result in wearing for acquired vein blood vessel
Thoroughly, the pain of patient is caused；Fixing means original simultaneously, for example use the adhesive tape of single side to secure the hose to and taken a blood sample
It is likely to that needle point is made to be close to vascular wall on the arm of person, causes to take a blood sample unsmooth.
Utility model content
The purpose of this utility model is to provide a kind of blood taking needles from strap retainer, it is intended to solve needle during blood sampling
The technical issues of handle is unstable and needle point can be close to vascular wall.
In order to achieve the above object, the base case of the utility model are as follows: a kind of blood taking needle from strap retainer, including needle
Head, needle handle, hose, puncture needle, protective sleeve of syringe needle and puncture needle protective case, the needle handle are equipped with DR tape, set on hose
There is the cushion block for padded needle handle, cushion block is equipped with the slide opening passed through for hose, and cushion block is slidably connected with hose, and cushion block is for padding
The end face of high needle handle is inclined-plane, and the tilt angle on cushion block inclined-plane is less than 40 degree.
The working principle of this base case is: when being taken a blood sample using this blood taking needle, removing protective sleeve of syringe needle and puncture needle is protected
Sheath punctures into syringe needle in blood vessel, pushes cushion block to slide on hose, makes cushion block pad on the downside of needle handle, thus needle handle and people
It is tilted a certain angle between body skin, so that needle point is located at endovascular middle part, needle point is avoided to be close to vascular wall, then opened double
Layer adhesive tape, adhesive tape is glutinous on the skin, it realizes the fixation of needle handle, that is, realizes the fixation of syringe needle, then by puncture needle and vacuum
Heparin tube connection, blood was collected.
The beneficial effect of this base case is:
1. syringe needle is taken a blood sample, needle handle is fixed by DR tape, that is, the fixation for realizing syringe needle makes medical staff
Syringe needle will not be had an impact in operation, generation syringe needle is avoided to puncture the accidents such as blood vessel.
2. this programme is by setting cushion block, for the tilt angle of cushion block less than 40 degree, cushion block can be used for padded needle handle, make needle point
Part is located in the middle part of blood vessel, prevents needle point to be close to vascular wall and causes the unsmooth of blood sampling.
Further, cushion block is equipped with the clamping unit for grip both hose.
After blood sampling completion or blood sampling volume are up to standard, clamping unit clamps hose, to prevent the blood in hose from occurring
Countercurrently.
Further, the cushion block includes upper head plate, front end-plate and end plate, front end-plate and end plate respectively with upper head plate two
End is hinged, and slide opening is provided on upper head plate；The clamping unit includes spring, locating piece and fastener, front end-plate and end plate
Between connected by spring, front end-plate and end plate are not formed by locating piece and fastener with the hinged one end of upper head plate and are buckled
Connection.
Snapping connection between front end-plate and end plate can be realized the clamping to hose and block blood sampling in this programme, and
Spring has then flexibly adapted to the support and compression to front and back end panel, and what is used snaps connection and can not use it
His additional materials can be such that front end face and rear end face engages, to reduce costs.
Further, the front end-plate is arranged with upper end board ends diagonally downward respectively with end plate, front end-plate and end plate
Tilt angle is identical.
In this programme front end-plate with end plate tilt angle it is identical can guarantee to needle handle carry out it is padded when, to needle handle
More stable support is formed, and front end face and rear end face can be realized padded to needle handle progress and be supported in this programme,
Flexible and convenient operation.
Further, the DR tape includes the first tunic and the second tunic, the lower surface of first tunic and needle handle
The upper surface of bonding, the lower surface bonds of the upper surface of the first tunic and the second tunic, the second tunic is equipped with protective film, the second layer
The length of film is greater than the length of the first tunic.
The length that the length of the second tunic is greater than the first tunic in this programme can be such that the second tunic tears from the first tunic
It is operated when opening more convenient.
Further, the tilt angle on the inclined-plane of the cushion block is 5~30 degree.
The inclined-plane of cushion block is used for the needle handle of padded blood taking needle, therefore angle cannot be excessive, and excessive angle is easy to pierce through blood
The pain of blood sampling person is managed and causes, the tilt angle on cushion block inclined-plane is too small and does not play the purpose of padded blood taking needle needle handle, and
Being close to and avoiding piercing through blood vessel for needle point and vascular wall can be preferably avoided using 5~30 degree of angles.
