Abstract
The utility model relates to a spring lancet device used for blood testing, which can replace a lancet and a positioning sleeve. The utility model is composed of a replaceable lancet, a positioning sleeve, a connecting socket and an adjusting socket. Compared with a traditional spring lancet, the utility model can realize the disposable use or the disinfection of the lancet and the positioning sleeve, so the utility model can effectively prevent the cross infection of viruses. Compared with the method that the lancet is directly held by hand, the utility model can relieve the tension and the pain of a patient, and can accurately control the size and the depth of a punctured incision.
Description
This utility model relates to a kind of device of lancet of blood count use.
Blood count needs skin is punctured in the medical treatment, obtains blood sample.Past is extensive use of spring lancet, makes by thorn person to ease the pain.The wound that punctures is controlled at the rational size and the degree of depth, but this spring lancet is difficult to sterilization, because the lancet sterilization is unclean.Often cause by thorn person's viral cross infection, especially the virus of blood-borne is brought serious problems.
For addressing this problem, present way is to forbid to use spring lancet, puncture by thorn person's finger skin and grasp lancet, obtain blood sample, because lancet only uses once after sterilization, has overcome viral cross infection, but because the speed of straightforward manipulation lancet prick skin is slow, to puncture process time long, cause pain to increase, and the wound size degree of depth is restive.
The purpose of this utility model provides the spring lancet device of a kind of fast changeable lancet and positioning sleeve, it can change lancet and locating cover easily, thorn knife needle, the practicable disposable use of locating cover or sterilization back are reused, thereby can prevent the cross infection of virus effectively; Alleviate by thorn person's pain; Reasonably control punctures size, the degree of depth of wound; The spring lancet of a new generation is provided for medical blood count.
This utility model is achieved in that changing pin type spring lancet device front end a lancet that connects by recessed garden conical surface friction, and one in its outside cover is crossed the positioning sleeve that adjustment seat garden post matching part is connected by the pyramidal projections more than 3.After lancet used once, the operator can take off positioning sleeve and lancet respectively, change another set of new or through disinfectant lancet and positioning sleeve, thereby prevented viral cross infection; Positioning sleeve is threaded on the adjustment seat through spiral shell simultaneously, the rotation adjustment seat.Then regulated the overhang of lancet relative localization cover, so accurately controlled size and the degree of depth that lancet punctures wound.
Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.
Fig. 1 is the profile according to the needle-changing type spring lancet device that the utility model proposes.
Fig. 2 is the cutaway view of Fig. 1 needle-changing type spring lancet device along the A-A line.
Describe details and working condition in detail below in conjunction with Fig. 1 Fig. 2 according to the concrete device that the utility model proposes.
This lancet device is made up of lancet (2), Connection Block (3), positioning sleeve (1), adjustment seat (4) and procapsid (8), friction is connected lancet (2) by＜5 ° of garden conical surfaces (17) and Connection Block (3), has the junction of a positioning sleeve (1) itself and adjustment seat (4) that pyramidal projections (15) composition inscribe garden more than three is arranged in its outside.Its diameter dimension is less than the diameter dimension at adjustment seat (4) post position, maximum cooperation garden (16), when positioning sleeve (1) with the position on every side of the pyramidal projections (15) of adjustment seat (4) its positioning sleeve (1) when linking to each other elasticity takes place, distortion, the maximum that makes pyramidal projections (16) cross adjustment seat (4) cooperates post position, garden.Positioning sleeve (1) firmly is connected with adjustment seat (4), thereby makes positioning sleeve (1), lancet (2) realize fast quick-mounting folding with adjustment seat (4), Connection Block (3) respectively.Adjustment seat (4) is connected rotation adjustment seat (4) with housing (8) by regulating screw thread.Then regulated the overhang of lancet (2) relative localization cover (1), overcome because the defective that the foozle of lancet (2) tapered hole brings this overhang to change, punctured the size of wound and the degree of depth in the scope that requires thereby accurately controlled lancet.
A pull handle (7) is connected with Connection Block (3) by pin (5), a garden post spring (10) one end acts on Connection Block (3), its other end acts on back casing (9), procapsid (8) is connected by screw thread with back casing (9), a knob (6) is enclosed within on the Connection Block (3), its both sides are adorned a garden post spring (12) respectively, and this spring masterpiece is used for knob (6) and is the trend of moving upward.
When pull handle (7) moves along direction shown in the arrow (11), then connected Connection Block (3) and lancet (2) move together, the thorn of Connection Block (3) compression simultaneously needle spring (10), two oblique breach of its below are crossed knob (6) and are moved to the back casing front end, when the openhanded pull handle (7) of opening, pull handle (7) then, Connection Block (3) and lancet (2) move along rightabout shown in the arrow (11), knob work surface (13) blocks on the work surface (14) of the oblique groove on the Connection Block (3), lancet is in treats the operating position.
When hands knob (6), Connection Block (3) is situated between to be taken off, and it moves to the locating surface of procapsid (8) to rightabout shown in the arrow (11) under thorn needle spring (10) effect, and the outstanding positioning sleeve (1) in lancet (2) tip is finished the action of thorn blood.
Claims (2)
1, the spring lancet device of replaceable lancet and positioning sleeve blood count use, form by lancet (2), Connection Block (3), positioning sleeve (1), adjustment seat (4) and procapsid (8), it is characterized in that lancet (2) is connected with Connection Block (3) friction by the garden conical surface (17), have its junction with adjustment seat (4) of a positioning sleeve (1) to have the pyramidal projections (15) more than three to cooperate post position, garden (16) to be fastened and connected with the maximum of adjustment seat (4) in its outside, adjustment seat (4) is connected by regulating screw thread with procapsid (8).
2, according to the described device of claim 1., it is characterized in that inscribe garden diameter that the pyramidal projections (15) of positioning sleeve (1) the forms diameter less than adjustment seat (4) post position, maximum cooperation garden (16), the elasticity by positioning sleeve (1) when the two is continuous makes its pyramidal projections (15) cross post position, maximum cooperation garden (16).
