Abstract

The utility model relates to the field of medical instruments, in particular to a novel foldable syringe. The novel foldable syringe comprises a needle tube and a piston piece, wherein the piston piece comprises a piston head, a piston support and a rotary foldable handle; the piston head is connected to the lower end of the piston support; the rotary foldable handle is hinged to the piston support; the length of the rotary foldable handle ensures that when the piston head is positioned downmost in the inner chamber of the needle tube, the tail part of the rotary foldable handle extends out of the inner chamber of the needle tube, and when the piston head stretches upmost in the inner chamber of the needle tube, the tail part of the rotary foldable handle is fastened at the lower edge of the needle tube after the rotary foldable handle is rotated. The novel foldable syringe can serve as not only a common syringe but also a negative-pressure instrument and has the advantages of small size, light weight, portability and multiple functions.

Description

New type foldable syringe

Technical field

This utility model relates to medical instruments field, is specifically related to a kind of new type foldable syringe.

Background technology

Clinical needs are promoting the development of science and technology, and injector technology presents rapid growth momentum, and dissimilar syringe is come out one after another.Existing these syringes play the effect of negative pressure drainage after can only playing injection or repacking, but the piston rod of conventional syringe is oversize, volume is large, operate and carry inconvenience, while fixing with drain, fault is many, meanwhile, at present conventional external negative pressure apparatus carries inconvenience, takes off the defects such as pipe, plugging as negative-pressure vacuum bag, negative pressure drainage vessel etc. all exist, and the carrying of patient, pipeline are fixed and nursed and bring inconvenience.

Moreover say in special fields such as fight of army, navigation space flight, field works and often need flexible medical services, but the demand that can meet these special dimensions realizes multi-purpose armarium scarcity, has affected the carrying out of all kinds of activities.For this reason, need to design a kind of simple in structure, easy to carry, simple operation and combined syringe, this combined syringe can be applicable to many-sided equipment configurations such as army's field dressing, navigation space flight medical treatment, field rescue.

Summary of the invention

The purpose of this utility model is: provide that a kind of volume is little, lightweight, easy to carry, function is many, can serve as ordinary syringe and use the new type foldable syringe that can serve as again negative pressure apparatus.

This utility model is achieved through the following technical solutions: this utility model comprises needle tubing and piston piece, and described piston piece comprises piston head, piston holder, rotary folding handle;

Described piston head is connected in piston holder lower end, rotary folding handle is articulated with on piston holder, the length of rotary folding handle for be positioned at when piston head syringe intracavity below time, the afterbody of rotary folding handle extends syringe intracavity, in the time that piston head is stretched to syringe intracavity the top, after the rotation of rotary folding handle, the afterbody of rotary folding handle is buckled in the lower edge place of needle tubing.

Compared with technology before, the beneficial effects of the utility model are:

1, rotary folding handle can be rotated and make to needle tubing lower end that rotary folding handle and needle tubing are overlapping makes this utility model minimizing that takes up room, carrying convenience degree increases;

2, Novel stack type syringe can be used as ordinary syringe and uses, and can be used as again depression drainage device simultaneously and uses, and has improved the use approach of equipment, and volume after folding little, be convenient to fix, do not affect all kinds of action.

3, this utility model is simple to operate, and one hand can complete all operations were, can be competent at operating under the special environments such as fight of army, navigation space flight, field work of task.

Fig. 2 is the use schematic diagram of this utility model during as syringe;

Fig. 3 is U-shaped folder rotary folding schematic diagram;

Fig. 4 is the local schematic cross-section that amplifies in A place in Fig. 2.

Label declaration: 1-needle tubing, 2-piston head, 3-piston holder, 4-U type folder, 5-gag lever post, 6-perforate, 5-spring.

Detailed description of the invention

Below in conjunction with brief description of the drawings, this utility model is elaborated:

As shown in Figure 1, this utility model comprises needle tubing 1 and piston piece, and described piston piece comprises piston head 2, piston holder 3, rotary folding handle;

As shown in Figures 2 and 3, described piston head 2 is connected in piston holder 3 lower ends, rotary folding handle is articulated with on piston holder 3, the length of rotary folding handle for be positioned at when piston head 2 needle tubing 1 inner chamber below time, the afterbody of rotary folding handle extends needle tubing 1 inner chamber, in the time that piston head 2 is stretched to needle tubing 1 inner chamber the top, after the rotation of rotary folding handle, the afterbody of rotary folding handle is buckled in the lower edge place of needle tubing 1.

This utility model can use as two kinds of common medical apparatus and instruments simultaneously: while use as common syringe, rotary folding handle is not equivalent to the piston rod of ordinary syringe when rotary folding in needle tubing 1 cavity; When as external negative pressure instrumentation, thereby by the pull-up of rotary folding handle at one section of negative-pressure vacuum of the interior formation of needle tubing 1, afterwards rotary folding handle is rotated and make rotary folding handle and needle tubing 1 overlapping to needle tubing 1 lower end, this utility model length under this state shortens greatly, thereby user can be put it into very easily in pocket, therefore can not bring inconvenience to the action of user completely.

This utility model integrates two kinds of functions of conventional medical apparatus and instruments clinically, for healthcare givers brings convenience, and operate very simply, one hand can complete all operations were, the medical apparatus and instruments being therefore especially suitable as under the special environments such as fight of army, navigation space flight, field work uses.

Further, described rotary folding handle is U-shaped folder 4, on 4 two clamping parts of U-shaped folder, be respectively equipped with the gag lever post 5 extending in opposite directions, piston holder 3 upper end correspondences are provided with perforate 6, and gag lever post 5 stretches in opening and makes U-shaped folder 4 be located on piston holder 3 and can rotate taking perforate 6 places as the center of circle.

Further, the cross section of described piston holder 3 is cross.Decussate texture can strengthen the intensity of piston holder 3.

Further, as shown in Figure 4, the inner chamber of described perforate 6 is provided with spring 5.The opening of U-shaped folder 4 can better be opened after leaving needle tubing 1 inner chamber.

Using method of the present utility model is:

As shown in Figures 2 and 3, using this utility model when ordinary syringe is used, only need push gently U-shaped folder 4 two ends with two fingers makes U-shaped folder 4 clamping piston supports 3, the width that U-shaped folder 4 opens can be matched with the intracavity diameter of needle tubing 1, thereby make U-shaped folder 4 can in needle tubing 1, move up and down the effect of the piston rod that serves as ordinary syringe; When this utility model is during as external negative pressure apparatus, along with U-shaped folder 4 being mentioned and leaving behind needle tubing 1 chamber, U-shaped folder 4 naturally opens at U-shaped folder 4 two ends under self elastic reaction or the effect of combining with spring 5 elasticity, width that U-shaped folder 4 opens and the width of needle tubing 1 profile are matched, thus make U-shaped folder 4 rotatable and with needle tubing 1 overlaid.
