Examples
Referring to fig. 1 to 7, the present invention provides a technical solution: a self-care device for ulcer wound surface comprises a shell 1.
The shell 1 consists of a round barrel and a rectangular shell which are intersected, and the inner cavity of the round barrel is communicated with the inner cavity of the rectangular shell.
One side of the barrel of the shell 1 is provided with a replacement opening. The replacement opening is rotatably provided with a sealing cover 2. The sealing cover 2 shields the replacement opening of the shell 1. The shell 1 is fixedly provided with a lock, and the sealing cover 2 is fixedly provided with a lock catch matched with the lock.
The barrel of the shell 1 is internally fixed with a fixed shaft 3 which is coaxial with the shell 1. Gauze 4 is sleeved outside the fixed shaft 3. A rotating rod 5 parallel to the axis of the fixed shaft 3 is fixedly arranged in the rectangular shell of the shell 1. The rotating rod 5 is fixedly connected with the shell 1.
One side of the rectangular shell, which is far away from the barrel, is provided with a discharge hole. A stop block 6 is fixedly arranged at the discharge hole of the shell 1.
A first rotating roller 7 is rotatably connected in the rectangular shell of the shell 1. The first rotating roller 7 is parallel to the axis of the fixed shaft 3.
Both ends of the first rotating roller 7 are fixedly provided with fixed shafts which are coaxial with the first rotating roller 7, and the fixed shafts are rotatably connected with the shell 1. The shell 1 is fixedly provided with a motor, and an output shaft of the motor is fixedly connected with a fixed shaft on the first rotating roller 7.
A second rotating roller 9 parallel to the first rotating roller 7 is arranged above the first rotating roller 7. The second rotating roller 9 is fixedly connected with the shell 1. An arc-shaped magnet 10 coaxially arranged with the second rotating roller 9 is fixed on the outer side of the second rotating roller 9. The notch side of the arc-shaped magnet 10 faces to the discharge hole side and is inclined downwards.
The outer side of the arc-shaped magnet 10 is rotatably connected with an annular cylinder 11. The annular cylinder 11 is rotatably connected with the shell 1.
A first gear 8 coaxial with the first rotating roller 7 is fixed on the end circumferential surface of the first rotating roller 7. A second gear 12 meshed with the first gear 8 is fixedly connected to the circumferential surface of the end part of the annular cylinder 11.
The outer circumference of the annular cylinder 11 is uniformly provided with a plurality of arc plates 13, and the arc plates 13 are in limit rotation connection with the annular cylinder 11.
The arc-shaped plate 13 is fixedly connected with two rotating shafts 14. The annular cylinder 11 is fixedly connected with a fixed seat 16 corresponding to the rotating shaft 14. One end of the arc-shaped plate 13 is positioned between the two fixing seats 16.
One of the rotating shafts 14 is rotatably connected with the fixed seat 16, and a torsion spring is arranged between the rotating shaft and the fixed seat 16. One end of the torsion spring is fixed on the rotating shaft 14, and the other end of the torsion spring is fixed on one of the fixing seats 16.
An arc-shaped limit groove 17 is formed in the other fixed seat 16, and a limit block 15 positioned in the limit groove 17 is fixed on the rotating shaft 14 corresponding to the fixed seat 16 provided with the limit groove 17.
A cutter 18 is slidably connected to the end of each arcuate plate 13 remote from the annular barrel 11. The end of the arc-shaped plate 13 connected with the cutting knife 18 is provided with a chute. The end of the cutter 18 is fixedly connected with a T-shaped slide block, and the cutter 18 is in sliding connection with the chute of the arc plate 13 through the T-shaped slide block. A pressure sensor 19 is fixedly arranged in the chute of the arc-shaped plate 13. The T-shaped slider is in contact with the pressure sensor 19.
The outer sides of the arc-shaped plate 13 and the cutting knife 18 are fixedly connected with a rubber layer 20.
The arc-shaped plate 13 and the cutting knife 18 which are not positioned at the notch of the arc-shaped magnet 10 are attached to the annular cylinder 11 under the action of the arc-shaped magnet 10, and the torsion spring is in a twisted state. There is a gap between the lowermost arcuate plate 13 and the first rotating roller 7. The free end of the gauze 4 bypasses the rotating rod 5, passes through the gap between the arc-shaped plate 13 and the first rotating roller 7 and passes out of the discharge hole.
The arc plate 13 and the cutter 18 positioned at the notch of the arc magnet 10 are separated from the annular cylinder 11 under the torsion of the torsion spring.
The gauze 4 is gradually discharged from the housing 1 when the annular cylinder 11 rotates clockwise. When the annular cylinder 11 rotates anticlockwise, the arc-shaped plate 13 and the cutting knife 18 which are positioned at the notch of the arc-shaped magnet 10 rotate to the side close to the gauze 4 to cut the gauze 4 and fix the cutting end of the gauze 4.
The arcuate plate 13 and the cutting blade 18 are both ferrous materials. The annular cylinder 11 is made of magnetic conductive materials.
The pressure sensor 19 is electrically connected to the motor of the first rotating roller 7.
The arrangement of the rubber layer 20 increases the contact friction and allows for better transport of the gauze 4.
As shown in fig. 1 to 6, the states in the figures are all instantaneous state diagrams of the nursing device when in use.
Wherein: as shown in fig. 3, the arc plate 13 and the cutter 18 attached to the outer side of the annular cylinder 11 are attracted by the arc magnet 10, and the torsion spring is in a stressed state.
The arc plate 13 at the notch of the arc magnet 10 is not attached to the outside of the annular cylinder 11 because this position is not affected by the attraction of the arc magnet 10 at all, but is in the state shown in fig. 3 by the torsion spring. At this time, the limiting block 15 is located at the end of the limiting groove 17 and is at the maximum opening angle, i.e. the state shown in fig. 5.
Among the plurality of pressure sensors 19, when any one of the pressure sensors 19 receives a set pressure value, the motor for driving the first rotating roller 7 to rotate is controlled to stop operating.
The pressure sensor 19 on the arcuate plate 13 is in contact with the corresponding cutter 18.
When the patient needs to bind the ulcer wound surface of the foot or replace the old gauze 4, the patient can hold the shell 1 by hand and then start the motor to drive the first rotating roller 7 to rotate anticlockwise. The first rotating roller 7 rotates the first gear 8 counterclockwise, and the first gear 8 rotates the annular cylinder 11 clockwise through the second gear 12. The annular cylinder 11 drives the plurality of arc plates 13 to rotate clockwise, and the gauze 4 can be continuously conveyed to the outer side by the clockwise rotation of the plurality of arc plates 13 and the anticlockwise rotation of the first rotating roller 7.
The patient may then grasp the end of the gauze 4 with the other hand and may then perform a wrapping process on the foot.
In the process of following the clockwise rotation of the annular cylinder 11, the arc-shaped magnet 10 is fixedly arranged, so that the arc-shaped plate 13 and the cutting knife 18 which rotate to the outer side of the arc-shaped magnet 10 are adsorbed by the arc-shaped magnet 10 and attached to the outer side of the annular cylinder 11.
When the arc plate 13 and the cutter 18 are rotated to the position without the arc magnet 10, the corresponding areas of the arc plate 13 and the cutter 18 and the arc magnet 10 become smaller, and the adsorption force becomes smaller. When the attraction force is smaller than the force of the torsion spring (the positions of the arc-shaped plate 13 and the cutting knife 18 are that the corresponding areas of the cutting knife 18 and the arc-shaped magnet 10 are about to disappear), the arc-shaped plate 13 rotates clockwise through the rotating shaft 14 under the action of the torsion spring. The arc 13 rotates to a maximum opened state (i.e., the state shown in fig. 3) under the restriction of the stopper 15 and the stopper groove 17.
In the above process, the cutting knife 18 on the arc plate 13 will not contact with the gauze 4 in the conveying state, then in the process of continuing to rotate the arc plate 13, the arc plate 13 will rotate anticlockwise through the rotating shaft 14 by the blocking of the stop block 6, so that the arc plate 13 and the cutting knife 18 are close to the annular cylinder 11, and when the arc plate 13 and the cutting knife 18 are close to the adsorption range of the arc magnet 10, the arc plate 13 and the cutting knife 18 will be attached to the outer side of the annular cylinder 11 again. The above stated purpose is: that is, the first rotating roller 7 and the plurality of arc plates 13 are rotated and matched, so that the gauze 4 can be smoothly conveyed to the outside.
After the foot is wrapped by the patient himself, the motor is controlled to rotate reversely, the first rotating roller 7 rotates clockwise, the first rotating roller 7 drives the first gear 8 to rotate clockwise, the first gear 8 enables the annular cylinder 11 to rotate anticlockwise through the second gear 12, and the annular cylinder 11 drives the arc plates 13 to rotate anticlockwise.
The arc 13 in the open state is driven by the annular cylinder 11 to rotate anticlockwise, and the edge of the cutter 18 is close to the gauze 4 and contacts the gauze 4.
The gauze 4 is then pushed against the outside of the first rotating roller 7, after which the arc 13 is prevented from rotating anticlockwise by the rotating shaft 14 in the course of continued rotation of the arc 13, because the cutting knife 18 is limited by the arc surface on the outside of the first rotating roller 7. And the arc 13 is limited by the limiting block 15 and the limiting groove 17 not to rotate clockwise through the rotating shaft 14. The pressure acting on the end of the cutter 18 will thus increase, eventually the gauze 4 being cut off by the cutter 18.
During cutting, the cutter 18 will press the pressure sensor 19 and the pressure sensor 19 will reach the set pressure value, so that the motor will stop working, at which point the arc 13 will remain in this state, as shown in fig. 7.
When the motor stops rotating, the cutting knife 18 is limited and blocked by the cambered surface at the outer side of the first rotating roller 7 at this time, so that the arc plate 13 can not rotate anticlockwise through the rotating shaft 14, and the limiting block 15 and the limiting groove 17 of the arc plate 13 can not rotate clockwise through the rotating shaft 14, namely, the position of the arc plate 13 is fixed, so that the arc plate 13 can be used as a baffle, and further, external dust is prevented from entering the shell 1 to pollute the gauze 4. Meanwhile, the cut gauze 4 is still positioned in the gap between the arc-shaped plate 13 at the bottom and the first rotating roller 7, so that the gauze 4 is convenient to convey and use next time.
In the process that the gauze 4 is not cut, the first rotating roller 7 and the arc plates 13 are in rotating fit, so that the gauze 4 can move towards the shell 1, and the gauze 4 wrapped on the foot can be subjected to a certain tensile force, so that the wrapping effect is better.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
