Description

A kind of disposable safe tip hemostix of push type

Technical field

The utility model relates to medical blood taking instrument technical field more particularly to a kind of disposable safe tips of push type Hemostix.

Background technique

In medical blood taking field, disposable blood taking device is small in size with its, using safety operation is conveniently characteristic is cured deeply The welcome of shield personnel and patient largely use in each medical institutions and diabetic at present.This hemostix carries bullet Mechanism is penetrated, compact-sized, overall time uses, safe ready, therefore, has stronger market development potential.

Existing hemostix will first pull out protective case, then puncture skin tip using needle point when taking a blood sample operation Blood was collected, and the depth of blood sampling hour hands spine broken skin skin tip goes to feel by people, error larger, twists cap and opens inconvenience, no It is suitble to automatic assembly production chain, internal structure is complex, causes main body materials more, and equipment is complicated.

Utility model content

To overcome disadvantages mentioned above, the purpose of this utility model is to provide a kind of blood samplings of the disposable safe tip of push type Device, easy to use, component is seldom, and assembly is simple, is suitble to automatic assembly production chain.

In order to reach the goals above, the technical solution adopted in the utility model is: a kind of disposable safe end of push type The front end of tip hemostix, including head, shell, sliding sleeve, needle body and tail portion, the needle body is equipped with syringe needle, and the head is set in The head of the shell, the shell include first shell and second shell, and the first shell and second shell are integrally formed, And the first shell is in frustum cone structure, the second shell is in rectangular parallelepiped structure, is equipped with described in supplying inside the first shell The first movement slot of sliding sleeve axial movement, the head of the sliding sleeve can stretch out the first movement slot, in the second shell Portion is equipped with the retention bead fixed for the tail portion, is equipped in the sliding sleeve mobile for second for needle body axial movement Slot, the second shell with rear removable are connect, and are connected between the tail portion of the needle body and the tail portion for pushing The needle body Forward is so that the syringe needle goes out the spring outside the first shell from the preceding terminal spine of the sliding sleeve.

Further, the sliding sleeve is in the form of a column structure, and card slot is offered on the sliding sleeve, and the card slot has two groups, symmetrically The two sides of the sliding sleeve are distributed in, and the card slot originates in close to the front end of the sliding sleeve, terminates at the tail portion of the sliding sleeve, When being not used, card slot is in fastening state, in use, squeezing the head of the sliding sleeve, card slot is opened, and needle body is anti-because of spring Active force moment passes through the second shifting chute of sliding sleeve, and syringe needle moment exposes the head of shell, plays and pierces through human skin Effect.

Further, the tail portion is equipped with skirt outstanding, and manipulator is easier to catch bottom skirt simultaneously when assembling automatically And do not fall off, substantially increase production efficiency and yields.

Further, the needle body is equipped with the first protrusion, and the sliding sleeve is equipped with and matches with first protrusion Groove, first protrusion resist the tail portion of the sliding sleeve, prevent the syringe needle from exposing sliding sleeve head.

Further, the tail portion is equipped with the second protrusion, and second protrusion is equipped with a laterally projecting limit, described One end for fixing the spring is limited, the other end of the spring is connect with the tail portion of the needle body, is used in hemostix When end, needle point has prevented secondary use because the deformation of spring returns to enclosure interior.

Further, the head is equipped with groove type knob, and the head is in circular arc close to the part of the first shell Shape, the shape on the head of the first shell are matched with the shape on the head, and the head of the first shell is in arc-shaped, Meet anthroposomatology design.

A kind of disposable safe tip hemostix of push type provided by the utility model, spring is transported forward in the prior art When dynamic, be easily separated from tail portion, cause needle point that can not return to enclosure interior because of the deformation of spring, can not prevent secondary use and Unnecessary secondary injury can be generated to user of service, the utility model is because tail portion is equipped with cross spacing, complete stuck spring, So that spring can not be detached from tail portion, needle body is equipped in shell by sliding sleeve, and sliding sleeve head is exposed, and squeezes sliding sleeve head, sliding sleeve It moves downwards through the intracorporal limiting slot of shell and sliding sleeve tail portion is opened, needle body passes through sliding sleeve because of the reaction force moment of spring Shifting chute and syringe needle moment expose upper part of the housing, play the role of piercing through human skin, using rear syringe needle because of spring Deformation returns in shell, has prevented secondary use, and easy to use, component is less, and assembly is simple.
