Description
Technical field
This utility model relates to a kind of blood collection device, relates in particular to a kind of clamping structure of blood collection device.
Background technology
The known gathering-device that is used to collect blood of human body as the gathering-device of the disclosed blood of certain prior art, comprises bag and is located in upper and lower plate body, elastomer and the cramp of bag inside respectively.Elastomer is clamped between the upper and lower plate body of mutual pivot joint, and the place is formed with the grab that mutual fixing connects respectively in the middle of upper and lower plate body.This grab comprises from the medial surface of aforementioned plate body vertically extending vertical section and from vertical section terminal extended hook, thus utilize each hook mutual clamping, and cramp buckle a side edge that is fixed in upper and lower plate body.Be combined into blood collection device like this.
Yet, known blood collection device, though have the plurality of advantages of simplifying when making flow process and shortening assembler, but the overlap distance of its grab is too short, and structural strength is not good, after placing a period of time, often because the elastomeric elastic force effect outside contact of plate body up and down, make grab generation flexural deformation backward, thereby make upper and lower plate body break away from mutual clamping state.Therefore remain really to be improved.
The utility model content
Main purpose of the present utility model, be to provide a kind of clamping structure of blood collection device, it is by the transverse plate of each grab and the setting of side plate, thereby increase the overlap distance and the structural strength of each grab, can prevent the flexural deformation of grab effectively and because of the automatic break-off that caused of distortion.
In order to reach above-mentioned purpose, this utility model provides a kind of clamping structure of blood collection device, described gathering-device comprises bag, upper plate body, lower body and elastomer, the place is formed with the grab that mutual fixing connects respectively in the middle of described upper and lower plate body, wherein, the transverse plate that described grab comprises vertical section of extending from the medial surface of described plate body, extend from described vertical section terminal horizontal and be connected in described vertical section and transverse plate and be formed at the side plate of one side, and each described side plate is formed at its vertically not homonymy of section respectively.
The clamping structure of the blood collection device that provides according to this utility model, owing to be provided with the transverse plate and the side plate of each grab, thereby increased the overlap distance and the structural strength of each grab, can prevent the flexural deformation of grab and the automatic break-off that is caused because of distortion effectively.

The specific embodiment
Below in conjunction with accompanying drawing technology contents of the present utility model is elaborated.Yet the only for reference and explanation of accompanying drawing is not to be used for this utility model is limited.
Fig. 1-3 is respectively the broken section enlarged drawing and the combination appearance figure of upper and lower plate body of the present utility model and elastomeric three-dimensional exploded view, lower body.This utility model provides a kind of clamping structure of blood collection device, and blood collection device mainly comprises bag 10 (as shown in Figure 4), upper plate body 20, lower body 30 and elastomer 40, wherein:
Elastomer 40 can be the taper compression helical spring, be formed with the path annulus 41 of protuberance 211 neighborings that are socketed in upper plate body 20 on its top, be formed with the big footpath annulus 42 of protuberance 311 neighborings that are located in lower body 30 in addition in the bottom of elastomer 40, so that the dilatating and deformable of elastomer 40 is evenly also located firmly.
Figure 4 and 5 are respectively the assembled sectional view and the user mode cutaway view of this utility model blood collection device, during combination protuberance 311 neighborings of the big footpath annulus 42 of elastomer 40 being put into lower body 30, protuberance 211 with upper plate body 20 is connected in the path annulus 41 of elastomer 40 then, and upper plate body 20 pressed towards lower body 30 directions, make the axle bed 221 of upper plate body 20 be connected in the pivot 321 of lower body 30, be formed by connecting by the mutual clamping of first grab 212 and second grab 312.Bag 10 inside of again it being packed into, the periphery of bag 10 is by hot forming machine involution and reserves an opening, packs into for aforesaid semi-finished product.At last, pre-buried tubular configured joint 11 and exhaustor on open side (figure does not show) carry out involution with the hot forming machine to the open side of bag 10 again.
The left plate 33 that promotes lower body 30 during use moves to the right, the intermediate plate 31 and the broken line 34 of the joint of left plate 33 are upwards arched upward, and make first grab 212 and second grab 312 break away from fastening states, utilize the elastic force effect of elastomer 40 and upper and lower plate body 20,30 is pushed open.The intermediate plate 21,31 of upper and lower plate body 20,30 will produce the flexible deformation with broken line 24,34, and bag 10 expansions are strutted, so that the blood of human body is extracted collection.
The foregoing description is only for explanation usefulness of the present utility model, and be not to restriction of the present utility model, those skilled in the art are under the prerequisite that does not break away from spirit and scope of the present utility model, and the various equivalent structures of being made change all in scope of the present utility model.Protection domain of the present utility model is defined by the claims.
