In summary:

1) When the bracket 103 is working, please refer to FIG. 8. The bracket 103 can guide the syringe 300 to puncture into the puncture plug 102 of the sampling port in a safe manner. The specific usage method is as follows:

Step 1: Open the bracket 103, first rotate the bracket 103 counterclockwise 90°, and then push the guide rail 10311 to the end;

Step 2: place the syringe 300 horizontally and press down to install it on the bracket 103, rotate the bracket 103 clockwise by 90°, and pierce the needle into the puncture plug 102;

Step 3: push and pull the syringe 300 for sampling or injection;

The fourth step: Reverse the first and second steps of the operation steps.

2) The safety principle of bracket 103

It can be understood that, please refer to FIG. 9 together. In the sampling method of the general sampling port, the needle of the syringe 300 is perpendicular to the sampling port. 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 with the protection of the baffle 1015, the fingers on the back side of the baffle 1015 still have the risk of being injured in the case of a large disturbance.

However, the sampling port provided by the embodiment of the present application is equipped with a bracket 103, which changes the travel path of the needle of the syringe 300 before puncturing the sampling port from being perpendicular to the sampling port and the sampling operation of the finger, to changing the needle of the syringe 300 to be parallel to the sampling port and the finger. Even if a disturbance occurs, the needle of the syringe 300 fixed on the bracket 103 and parallel to the finger has extremely low possibility and ability of injuring the finger, thereby greatly improving the safety of sampling/injection.

3) When the bracket 103 is not in use, it can be snapped to the periphery of the puncture plug 102 of the sampling port, which acts as a protective cover and prevents the puncture plug 102 at the sampling port from being polluted, causing heat sources (allergens) ) into the blood.

In addition, the embodiment of the present application optimizes and adjusts the structure of the existing sampling port, which can satisfy various gestures for grasping the sampling port and increase the operating comfort.

Please refer to Figure 10 to Figure 12 together:

The first holding mode (holding mode 1): the index finger and middle finger press against the protrusion 1016 downwards, and the thumb presses the baffle 1015 upwards and downwards, and the friction force formed by pressing will fix the sampling port.

The second holding mode (holding mode 2): the index finger and middle finger clamp the protrusion 1016 below, and the sampling port is fixed by the friction between the protrusion 1016 and the index finger and middle finger.

The third holding mode (holding mode 3): pinch the bump 1016 with the thumb and index finger, and fix the sampling port by the friction between the thumb, index finger and the bump 1016 .

In the prior art, there are different designs for the sampling port, which can meet the basic usage requirements, but do not take into account the practicability, safety, comfort and usage habits of medical staff. For example, when some sampling port products are held in the second and third ways, the clamping force is relatively small due to the narrow clamping position of the second holding method, and the gripping stability of the third holding method is poor, and it is easy to be affected by the force of the pipeline. Interference causes swinging up and down in the direction perpendicular to the sampling port, and the grip is not good; some sampling port products can be held with three gestures, but the grip of the first holding method is not good, and the thumb is against the vertical stop The plate 1015 is subject to high pressure, the thumb hurts, and the user experience is poor; some sampling port products can be held by the grip method, which feels good to hold, but there is no baffle 1015, which may injure fingers.

Compared with the traditional sampling port, the pipeline sampling port 100 provided by the embodiment of the present application can take into account the functionality of holding multiple gestures and can protect fingers, so as to prevent finger damage caused by puncture errors, and the first, second, third grip Among the methods, the holding method 1 has the best grip stability and the best security, so this application mainly focuses on the holding method 1, which can satisfy the second and third holding methods while ensuring the best grip and user experience. holding operation.

In the sampling port provided by the embodiment of the present application, the baffle 1015 on the main body 101 is designed as a planar structure as a whole, and the baffle 1015 is designed with raised lines 1018, and the protrusion 1016 has a sufficiently wide size to ensure that when grasping , the fingers have a better experience (comfortable), and the grip is more secure.
