[0050] The present invention is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific implementation methods are only used to further illustrate the present invention and cannot be understood as limiting the scope of protection of the present invention. Technicians in this field can make some non-essential improvements and adjustments to the present invention based on the above application content.

[0051] Example:

[0052] like Figure 1 , 3As shown in Figures 4 and 5, the present invention provides a debridement and nursing device for patients with head injuries from falling, comprising a base 101 and a lifting frame 401. The base 101 is provided with an arc track 102 and a storage shell 106. A movable seat 301 is slidably provided in the arc track 102. A support cylinder 302 is provided on the movable seat 301. A lifting sleeve 402 is provided on the lifting frame 401. The lifting sleeve 402 is slidably provided in the support cylinder 302. A cross bar 403 is slidably provided at the end of the lifting frame 401. A shielding cover 201 is hinged at the end of the cross bar 403. A window is provided on the shielding cover 201. A headrest 103 is provided on the base 101. A fixing belt 104 is provided on the headrest 103. The headrest 103 is located at the center of the arc track 102. A flexible ring 202 is provided in the window provided on the shielding cover 201.

[0053] When the device is in use, the patient can lie on the headrest 103 and fix the patient's head by the fixing belt 104. During use, the height of the shielding cover 201 can be adjusted by lifting the lifting sleeve 402 in the supporting tube 302, and the movable seat 301 can be slid in the arc track 102 to adjust the position of the shielding cover 201. Since the headrest 103 is located at the center of the arc track 102, no matter where the movable seat 301 slides, the window opened on the shielding cover 201 faces the patient's head. The distance between the shielding cover 201 and the patient's head can also be adjusted by sliding the cross bar 403 on the lifting frame 401, and the angle of the shielding cover 201 can be adjusted by rotating the shielding cover 201 along the hinge point between the shielding cover 201 and the cross bar 403, so as to conveniently and quickly move the shielding cover 201 to a position close to the patient's head, and at the same time make the window on the shielding cover 201 cover the patient's head. After the position of the shielding cover 201 is adjusted, the flexible ring 202 contacts the patient's head, and the gap between the shielding cover 201 and the patient is sealed by the flexible ring 202, thereby avoiding secondary damage to the patient's wound. The shielding cover 201 can then isolate the patient's wound from the outside world, effectively preventing blood or water generated during the debridement process from splashing onto the patient's face, mouth and nose, and avoiding adverse effects on the patient during the debridement process. The shielding cover 201 can also drain water into the storage shell 106 to reduce pollution to the medical environment.

[0054] like Figure 1 , 4As shown in Figures 5, 7 and 8, in this embodiment, a rotatable knob 501 is provided on the lifting frame 401, and the knob 501 is connected to the support cylinder 302 through a height locking mechanism. The height locking mechanism includes a locking rod 601 which is arranged in the lifting sleeve 402 and can slide laterally. A wedge block 602 is provided at the end of the locking rod 601. A plurality of groups of locking grooves 303 are arranged on the support cylinder 302 along its axis at intervals. The wedge block 602 can penetrate the lifting sleeve 402 and be clamped in one group of locking grooves 303. A first elastic member 603 is provided between the locking rod 601 and the lifting sleeve 402. A propulsion assembly is provided on the knob 501, and the propulsion assembly is connected to the locking rod 601 to convert the rotation of the knob 501 into driving the locking rod 601 to slide. The propulsion assembly includes a driving wheel 502 arranged on the axis of the knob 501, and a first propulsion surface 503 and a second propulsion surface 504 are arranged at intervals on the circumference of the driving wheel 502. The distance between the first propulsion surface 503 and the axis of the knob 501 is greater than the distance between the second propulsion surface 504 and the axis of the knob 501. A push rod 505 is slidably arranged in the lifting frame 401, and one end of the push rod 505 abuts against the driving wheel 502, and the other end can abut against the locking rod 601.

[0055] In the initial state, the second pushing surface 504 on the knob 501 abuts against the push rod 505, and the push rod 505 is in a retracted state. The knob 501 is turned, and the first pushing surface 503 abuts against the push rod 505 during the rotation process, thereby pushing the push rod 505 to slide. During the sliding process of the push rod 505, it abuts against the locking rod 601, and then pushes the locking rod 601 to slide laterally until the wedge block 602 at the end of the locking rod 601 is stuck in one of the locking grooves 303 to fix the position of the lifting sleeve 402, thereby adjusting and fixing the height of the shielding cover 201.

[0056] like Figure 1 , 2As shown in Figures 4, 5 and 7, in the present embodiment, the knob 501 is connected to the movable seat 301 and the base 101 through a position locking mechanism, the position locking mechanism includes a movable plate 304 which can be laterally slidably arranged in the movable seat 301, a connecting rod 306 is arranged on the movable plate 304, the connecting rod 306 can be lifted and lowered and penetrated in the locking rod 601, a lifting rod 307 can be lifted and lowered on the movable seat 301, the lifting rod 307 extends out from the bottom of the movable seat 301, a clamping block 309 is arranged at the bottom of the lifting rod 307, a plurality of groups of tooth grooves 105 are arranged at intervals along the arc track 102 at the bottom of the base 101, the clamping block 309 can be clamped in one of the groups of tooth grooves 105, a linkage component connected to the lifting rod 307 is arranged on the movable plate 304, and the sliding of the movable plate 304 is converted into driving the lifting rod 307 to rise and fall through the linkage component. The linkage assembly includes a driving column 308 disposed on the lifting rod 307 . An inclined groove 305 is provided on the movable plate 304 . The driving column 308 is slidably locked in the inclined groove 305 .

[0057] When the lifting sleeve 402 is being lifted or lowered, the locking rod 601 is lifted or lowered on the connecting rod 306, so that the locking rod 601 can drive the connecting rod 306 and the movable plate 304 installed at the bottom thereof to slide horizontally during the horizontal sliding process. When the movable plate 304 slides horizontally, the lifting rod 307 is driven upward by the cooperation between the driving column 308 and the inclined groove 305, so that the blocking block 309 is stuck in one of the sets of tooth grooves 105 to fix the position of the movable seat 301 on the base 101, so that the position of the shielding cover 201 can be adjusted and fixed.

[0058] like Figure 5 , 7 As shown in FIG. 8 , in this embodiment, the knob 501 is connected to the cross bar 403 through a horizontal locking mechanism, and the horizontal locking mechanism includes a pull rope 407, and the two ends of the pull rope 407 are respectively connected to the two ends of the cross bar 403, and the pull rope 407 is located between the locking rod 601 and the push rod 505. In the process of rotating the knob 501 to drive the push rod 505, until the end of the push rod 505 abuts against the locking rod 601, the pull rope 407 can be clamped to prevent the cross bar 403 from sliding. In addition, it can be understood that in some embodiments, a friction block can be added to the end of the push rod 505 to prevent the pull rope 407 from slipping. In this way, the distance between the shielding cover 201 and the patient can be adjusted and fixed.

[0059] like Figure 2 , 5As shown in Figures 6 and 8, in the present embodiment, the knob 501 is connected to the shielding cover 201 through an angle locking mechanism, which includes a mounting frame 404 arranged at the end of the cross bar 403, a connecting seat 203 is arranged on the shielding cover 201, a gear 204 is fixedly arranged on the connecting seat 203, the gear 204 is rotatably arranged in the mounting frame 404, a tooth block 405 is arranged in the mounting frame 404 so as to slide laterally, the tooth block 405 can be clamped on the gear 204, the tooth block 405 is fixedly connected to one end of a pull rope 407, a second elastic member 406 is sleeved on the pull rope 407, and two ends of the second elastic member 406 are respectively in contact with the tooth block 405 and the mounting frame 404.

[0060] Since the pull rope 407 is located between the locking rod 601 and the push rod 505, the pull rope 407 can be deformed to pull the tooth block 405 to slide in the installation frame 404 when the push rod 505 pushes the locking rod 601, until the tooth block 405 is clamped on the gear 204 to fix the position of the gear 204. In this way, the angle of the shielding cover 201 can be adjusted so that the shielding cover 201 can fit the patient's head. In addition, the connecting seat 203 is detachably connected to the shielding cover 201, which is convenient for disassembly and replacement of the shielding cover 201, so as to facilitate cleaning and disinfection of the shielding cover 201, and at the same time, it is convenient to select a shielding cover 201 with a window of a suitable size according to the size of the wound.

[0061] Specific usage and beneficial effects of the present invention:

[0062] When the device is in use, the patient places his head on the base 101, and the patient's head can be fixed by a special supporting device, such as a headrest 103, a supporting frame, etc. After the patient's head is fixed, the movable seat 301 can be slid along the arc track 102 to adjust the position of the shielding cover 201, and then the lifting sleeve 402 can be lifted and lowered in the supporting tube 302 to adjust the height of the shielding cover 201, and the cross bar 403 can be controlled to slide on the lifting frame 401 to adjust the distance between the shielding cover 201 and the patient's head, and finally the shielding cover 201 can be rotated along the hinge point of the shielding cover 201 and the cross bar 403 to adjust the angle of the shielding cover 201, and the shielding cover 201 can be quickly moved to the patient's wound through multi-directional adjustment until the window of the shielding cover 201 covers the patient's wound, and finally the knob 501 is turned, and the knob 501 is rotated during the rotation process.
