Abstract
The utility model belongs to the technical field of medical instruments. For overcoming the technical problems in the current blood collecting operation process, the technical scheme adopted by the utility model is as follows: the painless blood collector comprises a cylindrical negative-pressure tube of which two ends are opened and is characterized in that a blood collecting needle isolating plate is arranged at one end in a cylindrical negative-pressure tube cavity, which is close to the cylindrical negative-pressure tube; blood collecting needle through holes are formed in the isolating board; the blood collecting needle and a spring cavity connected with the blood collecting needle are positioned in a negative-pressure tube cavity at the rear part of the isolating board; a piston is arranged in a negative-pressure tube cavity positioned at the rear part of the spring cavity; a piston rod extends into the negative-pressure tube cavity from the outside of the negative-pressure tube and is connected with the piston; and a spring release button is arranged on the outer wall of the negative-pressure tube. The painless blood collector disclosed by the utility model has the benefits of simple structure, high needle feeding speed, sufficient blood collecting quantity, capability of ensuring that patients have no pain feeling and achievement of the aim of quickly and conveniently collecting blood.
Description
Technical field
This utility model belongs to technical field of medical instruments, specifically is meant a kind of nothing pain hemostix.
Background technology
When the blood sampling chemical examination, be mostly that the blood sampling personnel choke by blood sampling patient's finger with hands at present,, carry out blood collection with blood sampling negative pressure pipe then then with the quick pierce of blood taking needle.This mode of operation, the one, bring pain to patient, because that the speed that blood taking needle thrusts skin keenly feel more soon is light more, to blood sampling personnel's operant level proposition high requirement; The 2nd, patient is prone to produce fear, causes local muscular tone, and what influence was taken a blood sample normally carries out; The 3rd, operator need with directly carried out hand by the blood sampling personnel and contact and form easily cross infection.
Summary of the invention
The purpose of this utility model provides a kind of nothing pain hemostix, to overcome existing technical problem in the present blood sampling operating process.
For realizing above-mentioned technical purpose; The technical scheme that this utility model adopts is: do not have the pain hemostix; Comprise the column type negative pressure cylinder of a both ends open, it is characterized in that: be provided with the blood taking needle division board at the negative pressure cylinder intracavity near an end of negative pressure cylinder, division board is provided with the blood taking needle through hole; Blood taking needle and the spring cavity that is connected with blood taking needle are positioned at the negative pressure cylinder intracavity at division board rear; Negative pressure cylinder intracavity at the spring cavity rear is provided with piston, and piston rod extend into the negative pressure cylinder intracavity by the negative pressure cylinder outside and links to each other with piston, on the negative pressure cylinder outer wall, is provided with the spring release-push.
The beneficial effect of this utility model is: simple in structure, inserting needle speed is fast, blood sampling volume is sufficient, and patient does not have pain, can reach fast, the purpose of convenient blood sampling.
Description of drawings
Accompanying drawing is the structural representation of this utility model.
Among the figure, 1, negative pressure cylinder, 2, division board, 3, blood taking needle, 4, spring cavity, 5, spring, 6, release-push, 7, piston, 8, piston rod.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment this utility model is further specified.
Shown in accompanying drawing, there is not the pain hemostix, comprise the column type negative pressure cylinder 1 of a both ends open; Be provided with blood taking needle division board 2 at the negative pressure cylinder intracavity near an end of negative pressure cylinder; Division board 2 is provided with the blood taking needle through hole, and blood taking needle 3 and the spring cavity 4 that is connected with blood taking needle are positioned at the negative pressure cylinder intracavity at division board rear, and the negative pressure cylinder intracavity at spring cavity 4 rears is provided with piston 7; Piston rod 8 extend into the negative pressure cylinder intracavity by the negative pressure cylinder outside and links to each other with piston 7, on the negative pressure cylinder outer wall, is provided with spring release-push 6.
During normal condition; Blood taking needle 3 is compressed in the spring cavity 4 by coupled spring 5, during use, the personnel's that taken a blood sample finger shutoff negative pressure cylinder 1 go out the pin end; Pulling piston rod 8; Negative pressure cylinder 1 produces negative pressure, and quilt blood sampling this moment personnel's hand blood focuses on the finger of shutoff negative pressure cylinder, presses release-push 6 retracting springs 5 this moment; Blood taking needle 3 is punctured by blood sampling personnel's finger by the blood taking needle through hole on the division board under the effect of elastic force fast, and patient can accomplish blood sampling work under analgic situation.
