DETAILED DESCRIPTION OF THE EMBODIMENTS

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] Please refer to Figures 1-6, A prone position pressure injury prevention device, including a receiving plate 100. A placement groove 700 is provided inside the receiving plate 100. The cross-section of the placement groove 700 is rectangular. The top of the placement groove 700 communicates with a sliding groove 300. The cross-section of the sliding groove 300 is circular. A sliding column 600 is slidably connected inside the sliding groove 300. The bottom of the sliding column 600 is rounded. A limiting ring 400 is sleeved on the top of the sliding column 600. The limiting ring 400 is integrally formed with the sliding column 600, which can increase the connection strength. And a convex head 200 passing through the top of the receiving plate 100 is vertically fixed at the top of the sliding column 600. The outside of the convex head 200 is polished to prevent damage to the face. A return spring 500 is sleeved inside the placement groove 700 at the position outside the sliding column 600. The return spring 500 is made of a stainless steel material component. The return spring 500 is located at the bottom of the limiting ring 400, which is convenient for the normal use of the return spring 500. A trigger assembly 800 capable of driving the convex head 200 to move up and down is arranged inside the placement groove 700. The trigger assembly 800 is connected to an external power supply and is controlled by an external controller.

[0028] During use, the entire device is located at the position of the patient's face. The patient's face is attached to the receiving plate 100, thereby squeezing the convex head 200 to move the sliding column 600 downward and compressing the return spring 500. During the operation, the trigger assembly 800 works. The trigger assembly 800 moves up and down. During the up and down movement of the trigger assembly 800, it contacts the bottom of the sliding column 600, moving the squeezed sliding column 600 upward, thereby driving the convex head 200 upward, so as to massage the patient's face. Through the back-and-forth up and down sliding of the trigger assembly 800, the patient's face is continuously massaged to prevent the patient's face from being in a squeezed state all the time and causing damage.

[0029] Among them, the trigger assembly 800 includes a trigger piece 801 that slidably contacts the bottom of the sliding column 600. Wave-shaped ring plates 802 are slidably connected to both sides of the bottom of the trigger piece 801. The wave-shaped ring plates 802 are made of stainless steel material and the outside is polished smoothly. And an elastic telescopic rod 805 is rotatably connected to the middle side position of the bottom of the trigger piece 801. The elastic telescopic rod 805 is a telescopic rod with a spring structure added inside, which belongs to the prior art and will not be elaborated here. The bottom of the elastic telescopic rod 805 is connected to a mounting plate 804. A driving piece is provided between the mounting plate 804 and the bottom of the placement groove 700.

[0030] During use, the driving member drives the mounting plate 804 to move inside the placement groove 700. During the movement of the mounting plate 804, the elastic telescopic rod 805 drives the trigger member 801 to slide on the corrugated ring plate 802. When the trigger member 801 slides on the corrugated ring plate 802, the trigger member 801 moves up and down when the corrugated ring plate 802 undulates, thus completing the up and down movement of the pressed convex head 200. When the trigger member 801 moves up and down, through the elastic connection of the elastic telescopic rod 805, the normal connection between the mounting plate 804 and the trigger member 801 is maintained.

[0031] Among them, the driving member includes a driving motor 806 vertically fixed in the middle of the mounting plate 804. The driving motor 806 uses a servo motor. A servo motor is a rotary actuator or a linear actuator that allows precise control of the angular velocity or the position, speed, and acceleration of a line; it includes a suitable motor connected to a sensor for position feedback; it also requires a relatively complex controller, usually a dedicated module specifically designed for servo motors, which belongs to the prior art and will not be elaborated here. The output end of the driving motor 806 passes through the bottom end of the mounting plate 804 and is connected with a driving gear 807. A toothed ring 808 is fixed at the bottom of the placement groove 700. The toothed ring 808 is adapted to the shape of the placement groove 700. The toothed ring 808 is meshed and connected with the driving gear 807. The driving motor 806 is connected to an external power supply and is controlled by an external controller.

[0032] During use, the driving motor 806 operates. The operation of the driving motor 806 drives the driving gear 807 to rotate. The rotation of the driving gear 807 meshes with the toothed ring 808. Since the toothed ring 808 is fixed, the driving gear 807 rotates around the toothed ring 808, and the driving gear 807 thus drives the mounting plate 804 to rotate inside the placement groove 700.

[0033] Among them, the trigger member 801 includes a trigger plate 801b that slidably contacts the bottom of the sliding column 600. The trigger plate 801b can be correspondingly divided into the same number as a row of convex heads 200 to facilitate triggering the pressed convex heads 200 individually. The bottom of the trigger plate 801b is rotatably connected to a base plate 801a. A support spring 801c is connected between the bottom of the base plate 801a and the base plate 801a of the trigger plate 801b. The elasticity of the support spring 801c is greater than the elasticity of the return spring 500 to prevent the sliding column 600 from not being lifted up, and both sides of the bottom of the base plate 801a are slidably connected to the corrugated ring plate 802.

[0034] During use, when the substrate 801a moves up and down on the corrugated ring plate 802, it drives the trigger plate 801b to contact the squeezed convex head 200, causing the convex head 200 to move upward. When the trigger plate 801b moves downward, the convex head 200 returns to the previously squeezed position. Through the continuous movement of the substrate 801a, the up and down movement of the convex head 200 is completed, and the massage is completed. Through the elastic support of the support spring 801c, it is possible to prevent the convex head 200 from being forcibly restored to its original position, which may cause harm to the patient's face.

[0035] Wherein, sliding grooves are provided on both sides of the bottom of the substrate 801a, rollers are arranged in the sliding grooves, and the sliding grooves are adapted to the corrugated ring plate 802.

[0036] During use, the substrate 801a can be easily slid on the corrugated ring plate 802 through the contact of the rollers on the sliding grooves with the corrugated ring plate 802, and the friction is reduced by the rollers.

[0037] Wherein, a connecting plate 803 is connected between the corrugated ring plate 802 and the placement groove 700.

[0038] During use, through the use of the connecting plate 803, the support and fixation of the corrugated ring plate 802 can be facilitated.

[0039] Wherein, convex points are evenly distributed on the convex head 200, which can increase the contact points during massage and facilitate blood circulation more easily.

[0040] Wherein, a traditional Chinese medicine groove is provided inside the convex head 200, and a traditional Chinese medicine ointment is provided inside the traditional Chinese medicine groove.

[0041] Through the traditional Chinese medicine ointment provided inside the convex head 200, drug blood circulation can be carried out during massage, and the damage caused by pressure can be further reduced.

[0042] Wherein, limiting pulleys are connected between both sides of the mounting plate 804 and the inside of the placement groove 700.

[0043] During use, through the use of the limiting pulleys, the position of the mounting plate 804 can be easily limited, preventing the mounting plate 804 from shifting, so that the driving gear 807 and the toothed ring 808 are no longer engaged, affecting normal use.

[0044] Wherein, the corrugated ring plate 802 includes a convex plate and a ring, and the convex plate and the ring are smoothly connected, so that when the corrugated ring plate 802 contacts the substrate 801a, excessive friction will not be generated, affecting normal use.

[0045] Working process: When the patient is in the prone position, the patient's face fits on the receiving plate 100, thus squeezing the convex head 200 to move the sliding column 600 downward, squeezing the return spring 500. During the operation, the driving motor 806 works, and the operation of the driving motor 806 drives the driving gear 807 to rotate. The rotation of the driving gear 807 meshes with the gear ring 808. Since the gear ring 808 is fixed, the driving gear 807 rotates around the gear ring 808. The driving gear 807 thus drives the mounting plate 804 to rotate inside the placement groove 700, and further drives the mounting plate 804 to move around the inside of the placement groove 700. During the movement of the mounting plate 804, the elastic telescopic rod 805 drives the substrate 801a to slide on the corrugated ring plate 802. When the substrate 801a slides on the corrugated ring plate 802, when the corrugated ring plate 802 undulates, it drives the trigger plate 801b on the substrate 801a to move up and down, thus completing the up and down movement of the squeezed convex head 200. When the substrate 801a moves up and down, through the elastic connection of the elastic telescopic rod 805, the normal connection between the mounting plate 804 and the substrate 801a is maintained, so as to massage the patient's face. Through the back-and-forth up and down sliding of the trigger plate 801b, the patient's face is continuously massaged to prevent the patient's face from being in a squeezed state all the time and causing damage.

[0046] The above is only a preferred specific embodiment of the present invention; however, the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its improved concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
