[0047] The hair absorption component 2 includes a connection box 201, and an absorption chamber 202 is provided at one end of the connection box 201, and a collection chamber 203 is provided inside the connection box 201, and the collection chamber 203 is connected with the absorption chamber 202 through a through hole; a partition 205 is provided inside the collection chamber 203, and a micro negative pressure pump 204 is installed inside the collection chamber 203, the micro negative pressure pump 204 is located on a side of the partition 205 away from the through hole, and the absorption end of the micro negative pressure pump 204 is connected to a pipeline penetrating the partition 205; a filter screen 206 is also provided inside the collection chamber 203 and is located on a side of the partition 205 facing the through hole, and the end of the pipeline is located between the filter screen 206 and the partition 205;

[0048] In summary, when in use, the hand holding component 1 is provided to facilitate people to use. At the same time, the hand holding component 1 is used to connect the hair scraping component 3 and the hair absorbing component 2. The hair scraping component 3 is used to scrape the hair of the patient who is undergoing surgery. When scraping the hair, the micro negative pressure pump 204 is turned on to generate negative pressure inside the collecting chamber 203, and negative pressure is generated inside the absorbing chamber 202 through the through hole. The absorbing chamber 202 is connected with the inside of the hair scraping component 3, so that broken hair can be absorbed when scraping the hair and stored in the collecting chamber 203, which is more convenient for people to use. At the same time, during the absorption process, the filter screen 206 is provided to prevent hair from entering the absorption end of the micro negative pressure pump 204.

[0049] Furthermore, an opening 207 is provided at the top of the connection box 201, a top plate 208 is provided at the top of the connection box 201, and a sealing plug 209 for sealing the opening 207 is provided at the bottom of the top plate 208;

[0050] When in use, the top plate 208 and the sealing plug 209 are separated from the opening 207 through the handle on the top of the top plate 208, so that the hair fragments collected in advance in the collecting chamber 203 can be cleaned;

[0051] At the same time, for the convenience of use, a one-way valve should be provided at the through hole. When negative pressure is generated inside the collecting chamber 203, the valve plate on the one-way valve opens, so that the broken hair enters the collecting chamber 203. When the negative pressure disappears, the one-way valve closes, so that the broken hair is always inside the collecting chamber 203, which is convenient for subsequent cleaning.

[0052] Furthermore, the hair shaving assembly 3 includes a device box 301, and a blade 302 is disposed at one end of the device box 301, and an opening 304 communicating with the absorption chamber 202 is opened at the other end of the device box 301;

[0053] The hair on the patient's skin surface is shaved by the blade 302 , and the shaved broken hair passes through the inside of the device box 301 and the opening 304 into the absorption chamber 202 , and finally into the collection chamber 203 .

[0054] Furthermore, a medical sponge strip 303 is provided at the bottom of the device box 301 facing the blade 302. Before shaving the hair, alcohol or iodine can be dripped onto the medical sponge strip 303. Figure 4 It can be seen that the tilt direction of the blade 302 and the position of the medical sponge strip 303 ensure that the medical sponge strip 303 will first contact the human skin before the blade 302 shaves the hair, so that the iodine or alcohol on the medical sponge strip 303 can disinfect and clean the skin again before shaving the hair, further ensuring the scraping effect.

[0055] Further, the pressure sensing component 4 includes a micro pressure sensor 401 disposed inside the groove 103, an elastic plate 402 connected to the detection end of the micro pressure sensor 401, and a mounting plate 403 connected to the elastic plate 402; the pressure sensing component 4 also includes a display panel 404 disposed on the top surface of the connecting portion 102; a control switch 9 for controlling the micro negative pressure pump 204 and the micro pressure sensor 401 is disposed on the gripping portion 101. The entire control system is an existing mature technology and will not be described in detail in this embodiment;

[0056] The mounting plate 403 is provided with a mounting groove 7, and an elastic block 8 is provided on the inner side wall of the mounting groove 7;

[0057] A fixing block 5 is fixed on the end surface outside the connection box 201, and an elastic buckle 6 is provided on the outer wall of the fixing block 5;

[0058] When in use, the fixed block 5 can be stuck in the installation groove 7, and the elastic buckle 6 and the elastic block 8 cooperate with each other. The materials of the two can be metal materials, so as to facilitate long-term plugging and unplugging; and after the fixed block 5 is connected to the installation block, the connection box 201 and the connection part 102 are connected. When the whole device is in use, it is necessary to apply a certain force to the blade 302 after the blade 302 contacts the patient's skin before scraping. At this time, the elastic plate 402 will produce a certain deformation. Once the pressure is too large, the elastic plate 402 will be compressed to the maximum limit and pressurize the micro pressure sensor 401, so that the pressure sensor receives the pressure signal and displays it on the display panel 404. The display panel 404 helps people know that the pressure is too large at this time, so as to better control the pressure when shaving hair within a certain degree;

[0059] In addition, the elastic plate 402 can be cancelled according to actual needs, and only the micro pressure sensor 401 is used to detect the pressure during scraping, and a certain range value is set according to the existing technology. When the pressure range is exceeded, an alarm is issued; for ease of understanding, the setting of the elastic plate 402 is added in the figure, and whether to add it or not depends on production needs.

[0060] In addition, considering the connection between the connection box 201 and the device box 301, and the replacement of the device box 301 as a whole, connection blocks 10 are provided on both sides of the device box 301, and a circular cavity 11 is provided inside the connection block 10, and a circular block 12 is provided inside the circular cavity 11, and a card block 13 located outside the connection block 10 is provided at one end of the circular block 12 through a connecting rod; support plates 14 are provided on both sides of the connection box 201, and card slots 15 matching with the card block 13 are provided on the support plates 14;

[0061] pass Figure 6 and Fig.10 It can be seen that the card slot 15 and the card block 13 are both vertical structures, and the card slot 15 is opened vertically. The card block 13 can drive the circular block 12 to rotate in the circular cavity 11, so that the card block 13 can be changed to horizontal and vertical. When the card block 13 is rotated to vertical, it corresponds to the card slot 15, so that the support plate 14 can fit with the device box 301, and the card block 13 will pass through the card slot 15. At this time, after rotating the card block 13 to be horizontal, the card block 13 can be used to connect the support plate 14 and the device box 301, that is, the connection box 201 and the device box 301 are connected, so that the connection box 201 and the device box 301 can be detachably connected.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
