Description
Technical field
The present invention relates to medical instrument, specifically a kind of fixed blood sampler of finger.
Background technique
Physical examination is done now be unable to do without blood drawing part.Health detection much will all check by blood analysis, because
This, blood drawing is health examination important link.
In order to guarantee the generation of cross-infection, current most of hospitals all use the acquisition work that finger blood drawing carries out blood sample
Make, finger blood drawing also mainly using disposable medical equipment blood was collected work, can thus generate a large amount of medical waste
Rubbish also brings the increase of spending, and tracing it to its cause is because bloodletting needle is difficult to carry out thorough disinfection comprehensively.
Meanwhile there are also some problems when carrying out blood work for this blood drawing mode, such as puncture and acquire needs two not
Same operating procedure, inefficiency, and when being drawn blood using disposable blood taking needle, medical staff must be with person to be sampled
It is in contact, the possibility of cross-infection cannot be avoided completely.
Summary of the invention
The purpose of the present invention is to provide a kind of fixed blood samplers of finger, to solve to propose in above-mentioned background technique
The problem of.
To achieve the above object, the invention provides the following technical scheme:
A kind of fixed blood sampler of finger, the multiplexing needle holder including operation box and with the split type connection of operation box are described

Embodiment 1:
Please refer to Fig. 1-4, a kind of fixed blood sampler of finger is answered including operation box 1 and with the split type connection of operation box 1
With needle holder 2, the operation box 1 is in " mouth " font, and 1 lower half of operation box is the lock chamber 4 of front and back two sides perforation, is multiplexed syringe needle
Seat 2 is slidably mounted on 4 inner top of lock chamber, offers push channel 11 on the inside of 1 upper half frame of operation box, logical in push
It is equipped with the compression leg 6 being slidably connected with it in road 11, is equipped with pricker 23 in the multiplexing needle holder 2；Blood sample is carried out in use device
It when collecting work, places a digit into lock chamber 4, by applying downward pressure to compression leg 6, compression leg pushes down on multiplexing syringe needle
It is broken that seat 2 assassinates pricker 23 and finger contact opponent's fingering, and device can be fixed on the enterprising enforcement of table top and use, and not need medical worker
It is contacted with person to be sampled, and is referred to by 4 opponent of lock chamber and be fixed, facilitated and carry out needle thorn work.
The multiplexing needle holder 2 includes pedestal 21, and 21 center of pedestal offers the first sliding groove chamber 22 of upper and lower ends perforation,
The pricker 23 is slidably mounted on inside first sliding groove chamber 22, and the height that the length of pricker 23 is greater than pedestal 21 makes on pricker 23
Lower both ends, which are stretched out on the outside of first sliding groove chamber 22, to be arranged, and has the rotary table magnetic sheet 24 for being integrated with formula structure at the top of pricker 23；
After the completion of blood sampling, will multiplexing needle holder 2 removed from operation box 1, can by the way that pricker 23 is extracted out out of first sliding groove chamber 22,
And then when carrying out disinfection to it, can guarantee in first sliding groove chamber 22 also can to adequate disinfection effect, enable devices to
Repeat using reducing expenses；Specifically, 22 lower inside of first sliding groove chamber opens up oriented first at its port
The expansion suction cavity 25 extended on the outside of sliding slot chamber 22, expansion suction cavity 25 by the negative pressure connecting tube 26 that is embedded in pedestal 21 with
Connector 27 on 21 side wall of pedestal is connected, and connector 27 is used to connect external blood storage device such as bags of blood etc.,
After pricker 23 is pierced into finger, the mode that can rise by using pricker 23, make blood inside in the case where outer pressure change by
22 bottom of first sliding groove chamber enters expansion suction cavity 25 and is delivered in the external memory of connection by negative pressure connecting tube 26,
It needs to distinguish larger mode of operation twice to solve the problems, such as to puncture, collect, improves the efficiency of blood collection.
In order to realize that pricker 23 can be realized automatic rising effect after puncturing finger skin, opened up inside the compression leg 6
The second sliding slot chamber 63 for having both ends to penetrate through is equipped with the connecting column 64 being slidably connected with it, connecting column 64 in second sliding slot chamber 63
Bottom is the rotary table slot 65 being recessed upwards, and permanent magnetism piece 66 is fixed at the top of rotary table slot 65, the rotary table slot 65 and pricker 23
24 shape size of rotary table magnetic sheet at top matches, and when being multiplexed needle holder 2 and being mounted on 4 top of lock chamber, pricker 23 protrudes into the
In two sliding slot chambers 63, permanent magnetism piece 66 and rotary table magnetic sheet 24, which are attracted each other, makes connecting column 64 and pricker 23 generate magnetic connection, when even
When connecing column 64 and moving in the vertical direction, it is able to drive pricker 23 and synchronizes movement；Specifically, on the second sliding slot chamber 63
Portion offered it is outwardly extending draw high channel 67, in drawing passageway 67 be equipped with the second compressed spring 68, outside connecting column 64
Be additionally provided on wall extend outwardly and with the protrusion ring that draws high channel 67 and be slidably connected, 68 upper and lower ends of the second compressed spring point
It is not connected to prominent ring bottom and draws high on 67 bottom surface of channel；When carrying out blood drawing process, whole 6 top surface of compression leg that presses makes pedestal 21
It is moved down with 23 entirety of pricker, changing after puncturing makes connecting column 64 not stress the pressing mode of compression leg 6, and connecting column 64 is in the second pressure
The jacking effect of contracting spring 68 is lower to be risen, and drives pricker 23 to rise, and then realize the outflow collecting work of blood.
Specifically, the compression leg 6 is located at the first filler ring 61 with outward extension on one section of outer wall in push channel 11,
And abutting has the first compressed spring 62 between 11 bottom surface of the first filler ring 61 and delivery channel, when removal is applied to 6 top of compression leg
Pressure after, by the effect of the first compressed spring 62 enable to compression leg 6 automatically rise return, facilitate and carry out multiplexing needle holder
2 dismantlement work.
Embodiment 2:
The difference from embodiment 1 is that lower part is equipped with the supporting plate 3 being slidably connected with 4 medial surface of lock chamber in the lock chamber 4,
3 top surface of supporting plate is in the arc-shaped to lower recess, is equipped with multiple spring levers 31 between 4 inner bottom surface of 3 bottom of supporting plate and lock chamber and is used for
Support, finger are placed on supporting plate 3, are relieved stress by spring lever 31, enable adaptation to carry out the finger of different thicknesses
Blood sampling work.
Embodiment 3:
The difference from embodiment 1 is that if it is desired to realize compression leg 6 can synchronous drive multiplexing needle holder 2 synchronize and be displaced
Effect, 6 bottom surface of compression leg and 21 top surface of pedestal are equipped with the velcro to match, in this way in the installation for carrying out multiplexing needle holder 2
When enable to multiplexing needle holder 2 and 6 bottom surface of compression leg occur bonded structure, enable 6 synchronous drive of compression leg be multiplexed needle holder 2 into
Row movement.
It is obvious to a person skilled in the art that invention is not limited to the details of the above exemplary embodiments, Er Qie
In the case where without departing substantially from spirit or essential attributes of the invention, the present invention can be realized in other specific forms.Therefore, no matter
