The cross-sectional view of the calparine cap of embodiment.
As shown in Figs. 1-2, a kind of calparine cap, including connection pedestal 1 and moving member 2；The connection pedestal 1 includes base section
101 and linkage section 102, the moving member 2 includes mobile section 201；The connection pedestal 1 and indwelling pipeline system connectivity, it is described
Linkage section 102 is set in the mobile section 201, is provided with inner volume between the mobile section 201 and the linkage section 102
3；By pulling the mobile section 201 and/or linkage section 102, so that 3 volume of inner volume increases, in the inner volume 3
Interior formation negative pressure is carried out drawing back blood examination and be looked by the negative pressure of formation.Internal appearance is provided between mobile section 201 and linkage section 102
Chamber 3, inner volume 3 are connected to indwelling pipe-line system by base section 101, by pulling the mobile section 201 and/or connecting
Section 102 is connect, be can be and only simply pulled on mobile section 201 and be fixedly connected with section 102, is also possible to only simply pull on linkage section 102, it is fixed
Mobile section 201 is also possible to towards opposite direction while pulling mobile section 201 and linkage section 102, can make internal appearance
The volume of chamber 3 increases, for example, when pulling direction of the mobile section 201 away from base section 101 to move, mobile section 201 and company
It connects and opposite sliding occurs between section 102, so that 3 volume of inner volume between the two increases, with certain sealing
Property in the case where, then certain negative pressure will be formed in inner volume 3 at this time, can be completed and draw back blood examination and look into, this operation is only
It needs the calparine cap itself of this patent can be completed to draw back blood examination and look into, does not need the external sources instrument such as external syringe, indwelling tube
Road system is in closed state always, will not therefore bring pollution, and patient is safer using remaining needle.Need exist for explanation
It is that indwelling pipe-line system can be remaining needle, can is the sub-assembly of remaining needle and inlying catheter, wherein base section 101 and company
It connects section 102 and is provided with inner cavity, so that entirely connection pedestal 1 while can also to move with indwelling pipeline system connectivity
Section 201 can be provided with inner volume 3 between linkage section 102, it is preferred that linkage section 102 is provided with mobile cavity, the movement
Chamber includes wide mouth part and slot end, and the slot end is connected to the base section 101, and the wide mouth part is far from the base section
101, the inner volume 3 includes the mobile cavity.
In a specific embodiment of the utility model, as shown in Fig. 2, further including fixed section 202, the fixed section
202 are tightly connected with the mobile section 201, by pulling the fixed section 202 to make the mobile section 201 away from described
The direction of base section 101 is mobile, and the volume of inner volume 3 increases, and then forms negative pressure in the inner volume 3, passes through shape
At negative pressure carry out drawing back blood examination and look into.Inner volume 3, inner volume 3 are provided between mobile section 201 and the linkage section 102
It is connected to indwelling pipe-line system by base section 101 and linkage section 102, when by pulling fixed section 202 to drive movement
When section 201 is mobile away from the direction of base section 101, enable to mobile section 201 and linkage section 102 that relative displacement occurs,
So that 3 volume of inner volume between the two increases, with certain leakproofness, then internal at this time hold
By certain negative pressure is formed in chamber 3, it can be completed and draw back blood examination and look into.
In a specific embodiment of the utility model, as shown in Fig. 2, the connection far from the base section 101
102 one end external circumferentials of section are provided with seal groove 4, and sealing ring 5 is provided in the seal groove 4, and the sealing ring 5 makes described
Mobile section 201 and the linkage section 102 are tightly connected.The leakproofness of inner volume 3 in order to further increase, by far from base
102 one end of linkage section circumferential direction of seat section 101 opens up the seal groove 4 for being provided with sealing ring 5, so that linkage section 102 and mobile section
201 can be tightly connected by sealing ring 5, then when pulling linkage section 102 and mobile section 201 generates relative motion,
Inner volume 3 can guarantee there is better sealing while volume increases, to be conducive to the formation of negative pressure, with better
Completion is drawn back blood examination and is looked into.What needs to be explained here is that the number of seal groove 4 and sealing ring 5 is not specifically limited, as long as can rise
The effect for increasing stability to prevention security risk, can be according to the length of linkage section 102 or the volume of inner volume 3
Size etc. carries out the adjustment of adaptability, for example seal groove 4 and sealing ring 5 are disposed as two double-round designs.
In a specific embodiment of the utility model, as illustrated in fig. 1 and 2, limit is provided in the mobile section 201
Block 6, the limited block 6 are skidded off out of described mobile section 201 to limit the linkage section 102.Limited block 6 can pass through limit
Hole is connected in mobile section 201, is also possible to the protrusion being directly fixed in mobile section 201, and the shape of limited block 6 is not yet
It is specifically limited, as long as identical technical effect can be played, due to external force between mobile section 201 and linkage section 102
Effect when being slided between each other, 3 volume of inner volume can be made to increase, if but linkage section 102 out of mobile section 201
It thoroughly skids off, that inner volume 3 will not have certain leakproofness, can not also play the role of drawing back blood examination and look into, as limit
Specific location and number of the block 6 in mobile section 201 also without limitation, can as long as can reach identical technical effect
It to be designed according to actual needs, is readily apparent that by those skilled in the art, no longer citing repeats here.
In a specific embodiment of the utility model, as illustrated in fig. 1 and 2, rubber plug is provided in the fixed section 202
7, the rubber plug 7 is tightly connected with the fixed section 202.In order to enable calparine cap can preferably complete puncture procedure, preferably
, linkage section 102 is provided with mobile cavity, and mobile cavity includes wide mouth part and slot end, and the slot end and the base section 101 connect
Logical, the wide mouth part is far from the base section 101, and the inner volume 3 includes the mobile cavity, wherein rubber plug 7 and fixed section
202 are tightly connected, and by puncturing to rubber plug 7, the connection with inner volume 3 can be completed by mobile cavity, while also may be used
It is connected to base section 101, so that calparine cap can still have reliably when carrying out with external source instrument and being connected to use
Leakproofness.
In conclusion the calparine cap of the utility model increases on the basis of not influencing its original function and draws back blood examination
Look into function, with remaining needle entire service life, can Reusability can be anti-in 72 hours service life of remaining needle
It is multiple to use, the correlative charges of remaining needle nursing is saved, it is easy to operate, without blood residuals in indwelling needle catheter, draws back blood examination and look into
In the process, indwelling pipe-line system is in closed state always, will not therefore bring pollution, and patient is safer using remaining needle.
The foregoing description of the disclosed embodiments can be realized professional and technical personnel in the field or using originally practical new
Type.Various modifications to these embodiments will be readily apparent to those skilled in the art, and determine herein
The General Principle of justice can be realized in other embodiments without departing from the spirit or scope of the present utility model.Cause
