Preferably, the second engaging structure 1036 may be a slot, the first engaging structure 1013 may be a engaging protrusion, and of course, the engaging protrusion may be a hemispherical protrusion, and the slot is a hemispherical slot, and the slot is engaged with the hemispherical slot through the hemispherical engaging protrusion, so as to play a role in fixing the bracket 103 when the bracket 103 is retracted.
In some embodiments, the body 101 is further provided with a recess 1014, the recess 1014 being capable of receiving at least a portion of the structure of the second extension 1033.
It can be appreciated that the groove 1014 can be disposed between the two first engaging structures 1013, when the two second engaging structures 1036 on the bracket 103 are engaged with the two first engaging structures 1013 on the main body 101 in a one-to-one correspondence manner (i.e. when the bracket 103 is retracted), the groove 1014 can accommodate the redundant structure of the end portion of the second extension portion 1033, so as to ensure that the bracket 103 is tightly matched with the puncture plug 102, and meanwhile, the bracket 103 occupies a smaller space when retracted, and the whole is more exquisite.
In some embodiments, the bracket 103 includes a cover 1037, the first extension portion 1032 and the second extension portion 1033 are both disposed on the cover 1037, and a cap 1038 is disposed on an inner sidewall of the cover 1037, so that the cap 1038 can be covered with the puncture plug 102 when the cover 1037 is in a non-working state, thereby achieving a dustproof purpose.
In this way, when the bracket 103 is retracted (inactive state), the cap 1038 on the cover plate 1037 can be tightly covered with the puncture plug 102, thereby protecting the puncture plug 102.
In some embodiments, body 101 includes baffles 1015, bumps 1016, and tubing connection end 1017. Wherein, baffle 1015 is used for protecting fingers facing away from the puncture side of injector 300, bump 1016 is arranged on one side of baffle 1015 facing away from puncture plug 102, during use, baffle 1015 and bump 1016 can be held by medical staff, and pipe connection end 1017 is arranged on bump 1016 and penetrates through bump 1016, and pipe connection end 1017 is used for connecting external pipe 200.
It should be noted that, referring to fig. 7, the connection between the pipe connection end 1017 and the external pipe 200 is made by bonding with a plastic adhesive (e.g. cyclohexanone), wherein the inner diameter of the pipe connection end 1017 is the same as the outer diameter of the external pipe 200, and the narrowest part of the pipe connection end 1017 is the same as the narrowest part of the external pipe 200, so as to avoid blood accumulation and coagulation caused by flux change of the external pipe 200.
Of course, according to the safety requirement, the baffle 1015 extends along the periphery of the puncture plug 102 to form an overall planar structure, which plays a role in omnibearing protection, so that the area of the existing baffle 1015 can be enlarged on the two sides of the sampling port along the pipeline direction to protect fingers holding the sampling port and exposed outside.
To ensure the holding stability, the baffle 1015 and the bump 1016 are provided with ribs 1018. For example, the ribs 1018 are disposed on the finger pressing position on the baffle 1015 and on the side walls on two sides of the protruding block 1016, so that the ribs 1018 can increase the friction between the finger and the main body 101, increase the gripping stability, and improve the safety.
It should be noted that, the main body 101 is an integrally injection molded structure, and the material of the main body 101 may be any material that is bio-friendly and is not easy to coagulate, such as PVC, PE, PP. Baffle 1015 and tab 1016 are part of the one-piece injection molded structure.
In some embodiments, baffle 1015 is further provided with a stopper 1019, stopper 1019 abutting bracket 103 to maintain bracket 103 in a fixed position when syringe 300 is fixed.
That is, when the bracket 103 is in the fully expanded state (this state is the state in which the syringe 300 is to be mounted), the stopper 1019 plays a role of a stopper, so that the bracket 103 can be kept in a stable state at the time of mounting the syringe 300 without affecting the mounting of the syringe 300 by the displacement due to the pressing deformation.
To sum up:
1) In the case of operation of the holder 103, referring to fig. 8, the holder 103 can guide the syringe 300 to pierce into the piercing plug 102 of the sampling port in a safe manner, and the following method is specifically used:
The first step is to open the bracket 103, rotate the bracket 103 counterclockwise by 90 ° and then push the rail 10311 to the bottom;
Secondly, horizontally placing and pressing down the injector 300 on the bracket 103, rotating the bracket 103 by 90 degrees clockwise, and puncturing the needle into the puncture plug 102;
Thirdly, pushing and pulling the injector 300 to sample or inject medicine;
And fourthly, reversely operating the first step and the second step.
2) Principle of safety of the bracket 103
It will be appreciated that referring to fig. 9, in the sampling method of the common sampling port, the needle of the syringe 300 is perpendicular to the sampling port, and under the condition of being disturbed, the needle of the syringe 300 is easy to pierce the finger on the same side of the baffle 1015, and even if the baffle 1015 is protected, the finger on the back side of the baffle 1015 still has a risk of being injured under the condition of being disturbed greatly.
The sampling port setting bracket 103 provided by the embodiment of the application changes the travel path of the syringe 300 needle before puncturing the sampling port from the sampling operation perpendicular to the sampling port and the finger into the sampling operation of the syringe 300 needle parallel to the sampling port and the finger, even if disturbance occurs, the possibility and the injury capability of the syringe 300 needle which is fixed on the bracket 103 and parallel to the finger are extremely low, thereby greatly improving the sampling/injection safety.
3) The bracket 103 can be clamped to the periphery of the puncture plug 102 of the sampling port under the condition of not being used, so as to play a role of a protective cover, and prevent the puncture plug 102 at the sampling port from being polluted, so that a heat source (allergen) enters blood during puncture sampling.
In addition, the embodiment of the application can meet the requirement of grasping the sampling port by various gestures and increase the operation comfort level by optimizing and adjusting the structure of the existing sampling port.
Please refer to fig. 10 to 12:
The first way of holding (holding one) is that the index finger and middle finger are pressed against the protruding block 1016, the thumb presses the baffle 1015 downward, and the friction force formed by pressing fixes the sampling port.
The second holding mode (second holding mode) is that the index finger and the middle finger clamp the lug 1016 at the lower part, and the sampling port is fixed by the friction force between the lug 1016 and the index finger and the middle finger.
The third holding mode (holding mode three) is to pinch the lug 1016 between the thumb and the index finger and fix the sampling port by friction force between the thumb, the index finger and the lug 1016.
In the prior art, different designs are arranged on the sampling port, so that the basic use requirement can be met, but the practicality, the safety, the comfort and the use habit of medical staff are not considered. For example, when the two-way and three-way holding is performed, the holding force is smaller due to the narrower holding position of the second holding way, the holding stability of the third holding way is poorer, the hand feeling is poor due to the fact that the third holding way is easy to swing up and down in the direction perpendicular to the sampling port, the three-way gesture holding can be performed on the first holding way, the first holding way has poor hand feeling, the thumb is propped against the vertical baffle 1015 and is stressed by larger pressure, the thumb is painful, the use experience is poor, the first holding way can be adopted for holding the first holding way, the holding hand feeling is good, and the risk of damaging fingers of the baffle 1015 is avoided.
Compared with the traditional sampling port, the pipeline sampling port 100 provided by the embodiment of the application can achieve the function of holding by various gestures and can protect fingers so as to prevent fingers from being damaged due to puncture errors, and the holding mode I has the best holding stability and the best safety in the holding modes I, so that the application mainly has the holding mode I, ensures the best holding and using experience and can meet the holding operation of the holding modes II and III.
According to the sampling port provided by the embodiment of the application, the baffle 1015 on the main body 101 is integrally designed into a planar structure, the convex blocks 1016 are wide enough, and the better experience (comfort) of fingers and more firm grasping are ensured when the fingers are grasped.
