Still as shown in fig. 1, the aforementioned washing liquid chamber 12 and the inner cover 126 are matched by a buckle 127, and a sealing strip is fixedly arranged on the inner side edge of the inner cover 126 along the circumferential direction, so that the washing liquid chamber 12 and the inner cover 126 are in a sealing state after being buckled, thereby preventing the external air pressure from influencing the pressure in the washing liquid chamber 12, and further enabling the washing liquid in the washing liquid chamber 12 to be smoothly sprayed out of the tank body 1. The bottom of the lotion cavity 12 is provided with a liquid outlet 125, the liquid outlet 125 is communicated with the top of the box body 1 to form a liquid outlet channel, the liquid outlet channel is provided with a liquid outlet pipe 124 corresponding to the top of the box body 1, the lotion can be discharged from the liquid outlet 124 through the liquid outlet 125 under high pressure in the lotion cavity 12, and then is sprayed out through the communicated hose 201 and the spray head 202, so as to smoothly wash the wound. Here, can directly hold the lotion in the lotion chamber 12, also can place the lotion bag in the lotion chamber 12, the entry of flowing back passageway arranges at will when placing the lotion bag, as long as with the opening of lotion bag and the entry intercommunication of flowing back passageway, guarantee that the lotion flows out smoothly can.

The four compression chambers 120 of this embodiment are respectively arranged at four corners of the box body 1, each compression chamber 120 is vertically arranged along the height direction of the box body 1, the opening of each compression chamber 120 is located at the bottom of the box body 1, the top of the compression chamber 120 is in one-way conduction to the lotion chamber 12, and an air inlet check valve 122 for allowing external air to enter in one way is arranged. Here, in order to further reduce the infection of the wound by external factors, a dust screen is further provided on the air inlet check valve 122.

Specifically, as shown in fig. 4, a pressure guide passage 121 is provided in the housing to communicate the top of the compression chamber 120 with the washing liquid chamber 12, the pressure guide passage 121 is provided with a pressure check valve 123 at an outlet portion of the washing liquid chamber 12, and the pressure check valve 123 forms a one-way communication from the compression chamber 120 to the washing liquid chamber 12. The intake check valve 122 is at least one valve disposed on the pressure guide channel 121, and certainly, a plurality of intake check valves may be disposed according to the actual use state, and the external air enters the pressure guide channel 121 through the intake check valve 122 and then is introduced into the washing liquid chamber 12 through the pressurization check valve 123, so as to achieve the pressurization effect inside the washing liquid chamber 12; here, the pressurizing check valve 123 is provided on the side wall of the washing liquid chamber 12 and is disposed adjacent to the inner lid 126, and the level of the washing liquid in the washing liquid chamber 12 is located below the pressurizing check valve 123, thereby further enhancing the effect of pressure difference on the washing liquid in the washing liquid chamber 12, and facilitating the discharge of the washing liquid from the drain pipe 124. In this embodiment, the intake check valve 122 and the pressurization check valve 123 may adopt the existing mature valve body structure, and the description thereof is omitted here.

In addition, a guide groove 104 is further formed in the housing, the guide groove 104 is parallel to and penetrates through the compression chamber 120, so that a mounting base of a guide rod 105 is formed, the guide pressure channel 121 is arranged on an extending path of the guide groove 104 in a yielding manner, and the guide channel is prevented from interfering with the penetrating guide groove 104, so that the normal sealing effect inside is prevented from being influenced.

As shown in fig. 2, the bottom frame 103 in this embodiment is disposed at the bottom of the box 1 in a size matching manner, the number and the position of the telescopic rods 102 correspond to those of the compression cavity 120, so as to achieve the synchronous action of the telescopic rods 102 in the compression cavity 120, and the telescopic rods 102 extend into the compression cavity 120 and then form a seal with the interior of the compression cavity 120, so as to ensure that the air pressure enters the wash liquid cavity 12 through the pressure guide channel 121. In this embodiment, the top end of the telescopic rod 102 is configured with an elastic rubber pad, the circumference of the elastic rubber pad is slightly larger than the inner diameter of the compression cavity 120, and after the telescopic rod 102 extends into the compression cavity 120, the elastic rubber pad and the compression cavity 120 are pressed against each other by interference to achieve the sealing effect inside the compression cavity 120. Of course, other ways of sealing the compression chamber 120 are possible and are only illustrated in this embodiment. And each telescopic rod 102 is provided with a clamping structure which can form a limit with the compression cavity 120, so that the telescopic rods 102 on the bottom frame 103 are prevented from being separated from the box body 1 in the process that the bottom frame 103 moves downwards relative to the box body 1.

It should be noted that the wound treatment device should ensure that the pressurized lotion sprayed out has the pressure suitable for cleaning the wound, and the washing pressure of the lotion should be controlled within the range of 4-15PSI, so according to the pressure formula, the sum of the cross sections of the four compression chambers 120 should be set according to the actually increased pressure, and the process can be calculated according to the existing calculation method. The handles 131 on the two sides of the box body 1 are held by hands, the box body 1 is lifted to move upwards relative to the bottom frame 103, then the two hands are loosened, the box body 1 slides downwards by means of the self-gravity of the box body 1, the telescopic rod 102 works in the compression cavities 120, pressure is formed, and the formed pressure is the ratio of the self-gravity of the box body 1 to the sum of the cross sections of the compression cavities 120. At this point, the liberated hands are ready for irrigation and wound treatment. Furthermore, the flow rate of the lotion discharged from the lotion chamber 12 can be controlled relatively by manually moving the casing 1 up and down relative to the bottom frame 103, thereby controlling the irrigation pressure for wound treatment.
