The arc-shaped silicone rubber pad 6 of examples 1 to 3 was placed in an environment containing colonies of the same concentration in a laboratory for 100 hours, and then the colonies distributed on the surface of the arc-shaped silicone rubber pad 6 were observed by taking it under a microscope, and the observations were recorded in the following table:
| examples | Record the results |
| Example 1 | The number of colonies distributed on the surface of the arc-shaped silica gel pad 6About 2.1 x 1000 |
| Example 2 | The number of colonies distributed on the surface of the curved |
| Example 3 | The number of colonies distributed on the surface of the curved |
The result recorded from the table above is analyzed, and it can be seen that the embodiment 3 is the best embodiment, and by adopting the above technical scheme, the process for preparing the arc-shaped silica gel pad 6 is simple in steps and easy to implement, and the prepared arc-shaped silica gel pad 6 has good comprehensive performance, is relatively soft, and has good antibacterial and anti-aging performance.
The working principle is as follows: in the finger stall with the sterile pressing function, the sleeve 1 is used as a structural main body of the finger stall and is simultaneously used for being sleeved on a finger punctured by a patient; the pressing unit 2 can fix the finger sleeve on the finger punctured by the patient and can press the puncture point on the finger of the patient; the adjusting unit 3 is used for adjusting the pressing degree of the pressing unit 2 on the puncture point on the finger of the patient and the firmness fixed on the finger punctured by the patient; the aseptic protection unit 4 is used for preventing the inside of the sleeve 1 from entering dust and bringing bacteria into the sleeve, and can effectively prevent the puncture point on the finger of the patient from being infected.
The using method comprises the following steps: during the use, slowly overlap this dactylotheca on the finger of patient puncture, and guarantee that second on the concave surface of arc silica gel liner 6 presses down the puncture point on patient's finger 23, then rotate threaded rod 15 through handle 16, drive arc clamp plate 8 towards patient finger motion, utilize first pressing portion 7 old firm fixing of this dactylotheca on patient's finger, utilize the second to press the puncture point on 23 pressing patient's finger, the hemorrhage condition of puncture point on the permeable protection casing 19 and the sleeve 1 observation patient's finger simultaneously, take off this dactylotheca when treating that puncture point does not bleed on patient's finger, when taking off, rotate threaded rod 15 through handle 16, drive arc clamp plate 8 and point motion to patient's finger dorsad, can slowly take off this dactylotheca.
The parts not involved in the present invention are the same as or can be implemented by the prior art. The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
