Description
Technical field
This utility model relates to technical field of medical instrument, particularly a kind of calparine cap.
Background technology
Calparine cap a kind ofly entry needle or sampling probe to be inserted thereon in use for infusing or the connector of blood sampling etc., and be threaded connection and be connected with other utensil, with this convenient treatment or sampling.Though existing calparine cap can meet general instructions for use; but it is all comparatively simple in its structure; the connection of suitable injection pin or sampling probe and relevant appliance; and be not easy to utilize it to carry out protectiveness storage to the syringe needle position that some have the sampling probe of special medical performance, thus in use, there is certain limitation.In addition, existing calparine cap also easily occurs that when plugging entry needle or sampling probe finger is by the problem of stabbing, and causes the practicality of calparine cap not good.
Utility model content
In view of this, this utility model is intended to propose a kind of calparine cap, can overcome the deficiency of existing calparine cap, has good practicality.
For achieving the above object, the technical solution of the utility model is achieved in that
A kind of calparine cap, comprise body, be provided with plug in one end of described body, also comprise and be formed at described intrinsicly to connect with plug, and the containing cavity of other end opening in body, be provided with the connecting portion for connecting described body in the open at one end of containing cavity on the body.
Further, the shrinkage pool of indent is formed on the body in the open at one end of containing cavity, the cylinder be fixed on body is provided with in the middle part of described shrinkage pool, described containing cavity prolongs and is opened on the end of described cylinder in described cylinder, and described connecting portion is be located at the female thread on described shrinkage pool inwall.
Further, inside by the free end of described cylinder, the outer peripheral face of described cylinder is the gradually little taper in cross section.
Further, the one end outer peripheral face of described body being close to described plug is formed with the annular concave platform of indent.
Further, anti-rolling tube is installed with in described annular concave platform place.
Further, the open at one end outer peripheral face of described body being close to described containing cavity is formed with anti-skidding lines.
Relative to prior art, this utility model has following advantage:
(1) calparine cap described in the utility model; by arranging containing cavity; can when sampling probe be inserted on calparine cap; the syringe needle of sampling probe is made to be placed in containing cavity; and protection liquid can be injected in containing cavity; and on calparine cap, connect respective members with closed containing cavity via connecting portion, can realize thus storing the protectiveness of sampling probe syringe needle, make calparine cap have good practicality.
(2) arranging shrinkage pool makes connecting portion be set to female thread, and the overall structure after calparine cap connection respective members can be made compacter.Cylinder being set and making containing cavity be placed in cylinder, can lead to its motion when twitching sampling probe.
(3) outer peripheral face of cylinder is that taper can be convenient to the connection of respective members on calparine cap.
(4) annular concave platform is set, anti-rolling tube can be clamped on annular concave platform, to avoid stabbing finger when being equaled calparine cap plugs by sampling probe.
(5) attended operation that anti-skidding lines can be convenient to calparine cap and other parts is set.

Detailed description of the invention
It should be noted that, when not conflicting, the embodiment in this utility model and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe this utility model in detail in conjunction with the embodiments.
The present embodiment relates to a kind of calparine cap, as shown in Figures 1 and 2, it comprises body 1, plug 5 is provided with in one end of body 1, also comprise and be formed at connecting with plug 5 in body 1, and the containing cavity 4 of other end opening in body 1, body 1 is also provided with the connecting portion for connecting body 1 in the open at one end of containing cavity 4.
In the present embodiment, body 1 can by plastic warp injection mo(u)lding, and plug 5 is for being installed on the end of body 1, and a side end face of plug 5 leaks outside in the end of body 1.In the present embodiment, plug 5 can adopt rubber or silica gel material, and on body 1, the shrinkage pool 2 of indent is also provided with relative to the other end of plug 5, and in shrinkage pool 2, be also provided with the cylinder 3 be fixed on body 1, containing cavity 4 is namely by body 1 to prolong and in cylinder 3, and open-ended at cylinder 3 of containing cavity 4.
The connecting portion be arranged in the present embodiment on body 1 is be formed at the female thread 7 on shrinkage pool 2 inwall, and after adopting female thread 7 that calparine cap can be made to be connected with other component, its overall structure is comparatively compact, so that place and use.Certainly except being female thread 7, connecting portion also can be the external screw thread be formed on body 1 outer peripheral face, and now on body 1, still can arrange shrinkage pool 2 and cylinder 3, or also can not arrange shrinkage pool 2 on body 1, and make containing cavity 4 for running through body 1, open-ended with at body 1.
By the free end of cylinder 3 in the present embodiment, also namely the open at one end of containing cavity 4 is inside, and the outer peripheral face of cylinder 3 is the gradually little taper in cross section, now as shown in Figure 2, the outer peripheral face of cylinder 3 forms taper surface 6, designs this taper surface 6 and can be convenient to calparine cap and be connected with other component via female thread 7.And in order to avoid stabbing finger when sampling probe or entry needle being equaled plug 5 place on calparine cap and plugging, the one end being close to plug 5 in the present embodiment on the outer peripheral face of body 1 is also formed with the annular concave platform 8 of indent, and this annular concave platform 8 also can clamp a not shown anti-rolling tube.
Thus, by the setting of annular concave platform 8 and upper anti-rolling tube thereof, sampling probe or entry needle can be made to be restrained in anti-rolling tube, thus to avoid sampling probe or entry needle to stab finger because offseting because of carelessness.In the present embodiment as shown in Figure 1, for ease of the attended operation of calparine cap and other parts, the open at one end that the outer peripheral face of body 1 is close to containing cavity 4 is also formed with anti-skidding lines 9.Anti-skidding lines 9 can be the vertical raised structures shown in Fig. 1, and certainly except vertical raised structures, anti-skidding lines 9 also can adopt other version, as can be the block structure or multiple annular projections etc. of multiple projection.
This calparine cap in use; syringe needle one end of sampling probe is inserted in plug 5 place; and make the structural sections that on sampling probe, syringe needle one end need be protected enter in containing cavity 4; then in containing cavity 4, injection can protect liquid accordingly, finally use corresponding component to be closed by the opening of containing cavity 4 via female thread 7.When sampling probe need use; the component of closed containing cavity 4 opening can be taken off; pour out protection liquid; then sampling probe is promoted; sampling probe is stretched out by the opening of containing cavity 4; and change the extension elongation of sampling probe as required, finally by by female thread 7, the calparine cap with sampling probe is connected on corresponding component.
The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
