Description

A kind of disposable ear is combined hemostix

Technical field:

This utility model relates to a kind of medical apparatus and instruments, and especially a kind of disposable ear is combined hemostix.

Background technology:

When at present the patient being carried out the comprehensive blood sampling of ear, device commonly used is 11 ^#The tip knife blade.Because this knife blade does not have the function of control part bit depth and size, so blood sampling the time can only rely on medical worker's experience that the patient is taken a blood sample, the wound of blood sampling point is size, deep mixed often, causes unnecessary misery to the patient.

The utility model content:

This utility model provides a kind of disposable ear to combine hemostix, and it is simple in structure, and is reasonable in design, easy to operate, can effectively control the degree of depth and the size of the wound that stings, convenient blood sampling, safety and sanitation have alleviated patient's misery greatly, have solved problems of the prior art.

This utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: it comprises housing, the middle part is provided with a cavity in housing, be provided with a blade shaft in the cavity, insert in the blade axis hole blade shaft lower end, its end is provided with a blade, insert in the blind hole blade shaft upper end, and its end links to each other with spring in the blind hole; On the housing of cavity one side, be fixed with an elastic force tabletting, the elastic force catch perk end that is connected on the connecting rod of perk end in stretching into the housing internal cavity of elastic force tabletting and the cavity opposite side housing relative with the elastic force tabletting links to each other, and the position of corresponding elastic force catch is provided with a block that cooperates with the elastic force catch on blade shaft; On blade shaft, be provided with the restriction blade and stretch out the range line piece of length outside the housing; The position of corresponding blade is provided with out insert groove on the housing of blade axis hole lower end; Be provided with a through hole on blade shaft top, the position of corresponding through hole is provided with a slotted hole on housing, and blend stop inserts in slotted hole and the through hole.

This utility model is simple in structure, reasonable in design, easy to operate, during use, pull out blend stop earlier, to go out the insert groove aligning then and want blood sampling site, and firmly press the down spring tabletting, the elastic force tabletting drives the elastic force catch through connecting rod and breaks away from block, at this moment, blade shaft is overhanging under the elastic force effect of spring, drives blade moment to stretch out and thrust patient's blood sampling site from going out insert groove, under the effect of the range line piece on the blade shaft, the length that blade stretches out the insert groove outside can just make the degree of depth and the size to fit of the wound that stings, made things convenient for the medical worker smoothly from the blood sampling of patient ear, safety and sanitation have alleviated the misery in patient's blood collection procedure simultaneously greatly.

Description of drawings:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the front sectional structure sketch map of Fig. 1.

Fig. 3 looks the sectional structure sketch map for the right side of Fig. 1.

Among the figure, 1, housing; 2, cavity; 3, blade shaft; 4, blade axis hole; 5, blade; 6, blind hole; 7, spring; 8, elastic force tabletting; 9, connecting rod; 10, elastic force catch; 11, block; 12, range line piece; 13, go out insert groove; 14, through hole; 15, slotted hole; 16, blend stop.

The specific embodiment:

For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, the utility model is elaborated.

Shown in Fig. 1～3, this utility model comprises housing 1, and the middle part is provided with a cavity 2 in housing 1, be provided with a blade shaft 3 in the cavity 2, insert in the blade axis hole 4 blade shaft 3 lower ends, and its end is provided with a blade 5, insert in the blind hole 6 blade shaft 3 upper ends, and its end links to each other with spring 7 in the blind hole 6; On the housing 1 of cavity 2 one sides, be fixed with an elastic force tabletting 8, the elastic force catch 10 perk ends that are connected on the connecting rod 9 of the perk end of elastic force tabletting 8 in stretching into housing 1 internal cavity 2 and the cavity 2 opposite side housings 1 relative with elastic force tabletting 8 link to each other, and the position of corresponding elastic force catch 10 is provided with a block 11 that cooperates with elastic force catch 10 on blade shaft 3; On blade shaft 3, be provided with restriction blade 5 and stretch out the range line piece 12 of length outside the housing 1; The position of corresponding blade 5 is provided with out insert groove 13 on the housing 1 of blade axis hole 4 lower ends; Be provided with a through hole 14 on blade shaft 3 tops, the position of corresponding through hole 14 is provided with a slotted hole 15 on housing 1, and blend stop 16 inserts in slotted hole 15 and the through hole 14.Owing to bump elastic force tabletting 8 by mistake blade 5 is ejected before blend stop 16 can be avoided using, the situation that causes hemostix to lose efficacy takes place.

During use, at first pull out blend stop 16, to go out insert groove 13 then and aim at the position that to take a blood sample behind patient's ear, firmly press down spring tabletting 8 then, elastic force tabletting 8 drives elastic force catch 10 through connecting rod 9 and breaks away from block 11, and at this moment, blade shaft 3 is overhanging under the elastic force effect of

spring

7,5 moments of blade that drive its lower end are stretched out housing 1 outside from going out insert groove 13, thrust patient's blood sampling site.Range line piece 12 on the blade shaft 3 stops by the housing 1 of cavity 2 lower ends in the overhanging process of blade shaft 3, stretches out the length of insert groove 13 outsides in order to restriction blade 5, makes blade 5 thrust the degree of depth of the formed wound of patient's blood sampling site and is just the right size.The degree of depth that blade 5 thrusts is generally 0.1～0.2cm for well.

This utility model hemostix, simple in structure, easy to operate, safety and sanitation, can control the degree of depth and size that blade thrusts formed wound behind patient's blood sampling site effectively, make things convenient for the medical worker, alleviate the misery in patient's blood collection procedure greatly smoothly from the blood sampling of patient ear.

This utility model does not describe part in detail, is those skilled in the art of the present technique's known technology.
