DETAILED DESCRIPTION

[0014] The application will be further described in detail below in combination with the drawings and embodiments: As Figures 1-6 shown, a portable negative pressure suction device for wound treatment in burn department, comprising a box 1, a wheel frame 14 and a collection barrel 9, the wheel frame 14 and the burn collection barrel 9 are arranged in the box 1 respectively, a rotatable winding wheel 12 is arranged on the connecting shaft of the wheel frame 14, the winding wheel 12 is provided with a cavity, a clockwork spring 26 is arranged in the cavity, the clockwork spring 26 is sleeved on the connecting shaft of the wheel frame 14, a compression spring 15 and a pressure rod 19 are respectively arranged in the cavity of the wheel frame 14, the compression spring 15 is located at the bottom end of the pressure rod 19, the pressure rod 19 is provided with an arc block 16 on the side of the wheel frame 14, the arc block 16 is provided with a friction plate 18, the friction plate 18 is in contact with the inner ring of an anti-skid ring 11, the anti-skid ring 11 is arranged on one side of the winding wheel 12, a drainage tube 5 is wound on the winding wheel 12, one end of the drainage tube 5 is connected with a suction part, the other end of the drainage tube 5 is connected with a rotary joint 25 by penetrating into the cavity of the winding wheel 12, the rotary joint 25 is connected with a connecting pipe on the collection barrel 9, the collection barrel 9 is provided with a connecting port 32, and the connecting port 32 is connected with an air pipe on a negative pressure pump 8.

[0015] In use, the doctor can directly place the device beside the operating table, pull the drainage tube 5, and release the drainage tube 5 wound on the winding wheel 12 by rotating the winding wheel 12 on the wheel frame 14. When the length of the drainage tube 5 is appropriate for conveniently attracting the wound of the patient, the doctor does not need to pull the drainage tube 5 any more. Under the action of the compression spring 15, the pressure rod 19 always has an upward force, wherein the force provided by the compression spring 15 is always greater than the maximum force that can be provided by the clockwork spring 26, so that the friction plate 18 on the arc-shaped block 16 is tightly pressed against the anti-skid ring 11 on the winding wheel 12, the static state of the winding wheel 12 is maintained through the friction force between the friction plate 18 and the anti-skid ring 11, and the winding wheel 12 is prevented from rotating at will, so that the drainage tube 5 is not wound or retracted too short to affect the operation of the doctor. When the device is used up, the doctor only needs to press the pressure rod 19 to drive the arc-shaped block 16 to move downward, so that the friction plate 18 is separated from the anti-skid ring 11, the locking of the winding wheel 12 is released, and the winding wheel 12 rotates around the connecting shaft on the wheel frame 14 under the action of the clockwork spring 26, so that the drainage tube 5 is re-wound on the winding wheel 12, thereby realizing the effect of quick storage, and making the device more convenient to use and store.

[0016] In the embodiment, the main box cover 2 and the auxiliary box cover 3 are respectively hinged on the two sides of the box body 1, and the magnetic block 13 is arranged on the auxiliary box cover 3. The recesses in the main box cover 2 and the auxiliary box cover 3 are rotationally connected with the rotating frame 17, and the rotating frame 17 corresponds to the position of the magnetic block 13. In use, the rotating frame 17 is pulled to be perpendicular to the main box cover 2 and the auxiliary box cover 3, and the main box cover 2 and the auxiliary box cover 3 are conveniently opened by holding the rotating frame 17. After the main box cover 2 and the auxiliary box cover 3 are turned by 180 degrees, the rotating frame 17 is in contact with the magnetic block 13. The rotating frame 17 is made of metal material, and thus can be attracted by the magnetic block 13, thereby increasing the stability of the rotating frame 17, making the rotating frame 17 better support the main box cover 2 and the auxiliary box cover 3, avoiding shaking of the main box cover 2 and the auxiliary box cover 3, and making the main box cover 2 and the auxiliary box cover 3 form a stable platform, thereby facilitating the doctor to place articles and increasing the functionality of the device.

[0017] In the embodiment, the auxiliary box cover 3 is provided with two bases 30 arranged oppositely, the bases 30 are provided with two limiting grooves 29, and the placing frame 27 is rotationally connected to the bases 30. The spring sheet 28 is arranged on one side of the placing frame 27, and one end of the spring sheet 28 is clamped in one of the limiting grooves 29. After the auxiliary box cover 3 is unfolded, the spring sheet 28 is disengaged from the limiting groove 29 by being actuated, the locking of the placing frame 27 is released, and the placing frame 27 is rotated. When the placing frame 27 is perpendicular to the auxiliary box cover 3, the spring sheet 28 is clamped in the other limiting groove 29 under the action of the elastic force, and the placing frame 27 is locked. When the doctor does not need to attract temporarily, the attracting part can be placed on the placing frame 27, and the doctor does not need to find another position to store, thereby avoiding pollution.

[0018] In the embodiment, the suction part is composed of the hand-held rod 6 and the filter head 7, the filter head 7 is provided with a sealing ring 20 at the connection position with the hand-held rod 6, the hand-held rod 6 is provided with a sponge sleeve 21, and the other end of the hand-held rod 6 is connected with the drainage tube 5. When the doctor holds the hand-held rod 6, the sponge sleeve 21 can increase the friction force, so that the doctor can better operate, and the soft characteristic of the sponge sleeve 21 can increase the comfort when holding the hand-held rod 6; the sealing ring 20 can reduce the gap between the filter head 7 and the hand-held rod 6, so as to avoid the leakage, the filter head 7 can be replaced after use, so as to avoid the cross infection and the disinfection and cleaning of the whole device, and the working efficiency is improved.

[0019] In the embodiment, the collecting barrel 9 is provided with a limiting column 33, the limiting column 33 is provided with a slidable buoyancy sleeve 31, the buoyancy sleeve 31 is provided with a baffle 34, and the baffle 34 corresponds to the connecting port 32. When the waste liquid in the collecting barrel 9 is stored to the position of the limiting column 33, the buoyancy sleeve 31 drives the baffle 34 to rise under the action of the buoyancy, and when the waste liquid is collected to the maximum safe storage capacity of the collecting barrel 9, the baffle 34 just coincides with the connecting port 32, so as to cover the connecting port 32, thereby closing the connecting port 32, avoiding the negative pressure pump 8 from continuously extracting the air in the collecting barrel 9, so as to stop the negative pressure suction of the device, instead of the traditional liquid level display, and the doctor does not need to observe the waste liquid collection condition from time to time, thereby reducing the working burden.

[0020] In the embodiment, the box body 1 is provided with two handles 4 at the two sides, the box body 1 is provided with a partition plate 10 and a placing cylinder 23, the placing cylinder 23 is provided with a clamping block 24 clamped in the clamping groove 22 on the partition plate 10. When the device is accommodated, the handle 4 can be conveniently held by the doctor, the hand-held part can be placed in the placing cylinder 23, so as to avoid the damage caused by the random shaking in the box body 1, and the placing cylinder 23 can be quickly taken down through the hooking connection of the clamping block 24 and the clamping groove 22, so as to facilitate the cleaning and disinfection.

[0021] The above is only the embodiment of the application, and the specific technical solutions or characteristics in the scheme are not described in detail. It should be pointed out that, for those skilled in the art, without departing from the technical solutions of the application, some deformations and improvements can be made, which should be regarded as the protection scope of the application, and these will not affect the effect and practicability of the application. The protection scope of the application should be subject to the content of the claims, and the specific implementation mode in the description can be used to explain the content of the claims.
