Specifically, body 100 is connected with strap 200; the pressing part 60 can at least partially extend out of the lower end of the body 100 and is arranged on the body 100 in a manner of limiting rotation and being capable of moving vertically; the adjusting part 30 is located at the upper end of the body 100 and is arranged on the body 100 in a manner of limiting vertical movement and being capable of rotating relative to the pressing part 60; the first magnet ring 41 is arranged at the upper end of the pressing part 60, the first magnet ring 41 is formed by butting two arc-shaped magnets, and opposite magnetic poles of the two arc-shaped magnets face the same direction; the second magnet ring 42 is provided at the lower end of the adjustment portion 30, and is opposed to the first magnet ring 41; the second magnet ring 42 is formed by butting two arc-shaped magnets, and the opposite magnetic poles of the two arc-shaped magnets face the same direction; wherein: the adjuster 30 rotates the second magnet ring 42 to change the magnitude of the magnetic repulsive force between the second magnet ring 42 and the first magnet ring 41. Preferably, the first magnet ring 41 and the second magnet ring 42 are each formed by two semicircular magnet butt joints. Preferably, the body 100 includes a socket part 10 and a cylinder 20, the socket part 10 is sleeved on the cylinder 20 and is in threaded connection with the cylinder 20, and the upper end of the pressing part 60 is formed with the piston 70; the piston 70 is disposed in the cylinder 20; the lower end of the adjusting portion 30 is provided with a rotating core 31, and the rotating core 31 extends into the cylinder 20 from the upper end of the cylinder 20. Preferably, two baffle rings 33 are arranged on the wall of the cylinder 20 at the upper part of the cylinder 20, the rotating core 31 is positioned between the two baffle rings 33, a plurality of concave parts are arranged on the circumferential surface of the rotating core 31, and the plurality of concave parts are arranged in a circle along the circumferential direction; spring top balls are arranged on the wall of the cylinder body 20, and when the rotating core 31 rotates, the top balls of the spring top balls can be sequentially embedded in the concave parts, so that the adjusting part 30 can be kept at a rotated position after rotating (not shown in the drawing). Preferably, a vertical guide groove is formed on a wall of the cylinder 20 at a lower portion of the cylinder 20, and a guide key is provided on the piston 70, the guide key being disposed in the guide groove and being vertically movable along the guide groove (not shown in the drawings) so that the piston 70 is vertically movable. Preferably, the upper end of the adjustment part 30 is provided with a knob 32.
As described above, the pressing portion 60 can only move vertically but cannot rotate due to the cooperation of the guide key and the guide groove; the two stop rings 33 limit the rotation core 31, so that the adjusting part 30 can only rotate but cannot vertically move.
As described above, since the second magnet ring 42 and the first magnet ring 41 are provided in the adjuster 30 and the pressing portion 60, respectively, when the adjuster 30 is rotated, the relative positions of the magnetic poles of the second magnet ring 42 and the first magnet ring 41 are changed, and the magnetic repulsive force therebetween is changed (naturally, within a certain rotation angle range of the adjuster 30, magnetic attractive force can be generated between the first magnet ring 41 and the second magnet ring 42, and the magnetic attractive force can also be changed according to the rotation of the second magnet ring 42). In this way, the magnetic repulsion between the second magnet ring 42 and the first magnet ring 41 can be changed by rotating the adjustment portion 30, and the change of the magnetic repulsion can change the pressure applied to the bleeding part by the pressing portion 60, so that the pressure applied to the bleeding part by the pressing portion 60 can be changed by rotating the adjustment portion 30, and the requirement of the bleeding part on the pressure can be met.
The invention changes the pressure applied by the pressing part 60 by changing the relative rotation position between the two magnet rings, and has ingenious design. Since the magnetism of the two magnet rings does not change greatly with the increase of the use time and the use frequency, the pressing part 60 can provide sufficient stable pressure for the bleeding part.
In a preferred embodiment of the present invention, the pressing part 60 further includes a pressing head 61; a sleeve body 63 is arranged in front of the pressing head 61 and the piston 70, the piston 70 is in threaded and sealed connection with the upper end of the sleeve body 63, and the pressing head 61 is in threaded and sealed connection with the lower end of the sleeve body 63; the layered hemostatic cotton 62 is arranged at the lower end of the compression head 61, the compression head 61 is provided with a liquid guide hole 611 penetrating through the upper section and the lower section of the compression head, liquid absorbing cotton 612 penetrates through the liquid guide hole 611, one end of the liquid absorbing cotton 612 extends into the sleeve body 63, and the other end of the liquid absorbing cotton 612 is in contact with the hemostatic cotton 62; a space between the rotating core 31 and the piston 70 forms a containing space 80, the containing space 80 is used for containing liquid medicament, the piston 70 is provided with a first one-way valve 51, the inlet of the first one-way valve 51 is communicated with the containing space 80, and the outlet is communicated with the sleeve body 63; the rotating core 31 is provided with a second check valve 52, an inlet of the second check valve 52 is communicated with the outside, and an outlet is communicated with the accommodating space 80.
As can be seen from the above, when the adjuster 30 rotates, for example, when the adjuster 30 rotates once, there will be not only a varying magnetic repulsion force between the first magnet ring 41 and the second magnet ring 42, but also a varying magnetic attraction force, that is, the adjuster 30 necessarily has at least one rotation angle range, so that there will always be a magnetic attraction force between the two magnet rings when the adjuster 30 rotates in the rotation angle range.
As described above, the hemostatic device of the present invention can change the amount of magnetic force by rotating the pressing portion 60 in the first rotation range of the adjustment portion 30 while achieving a stable pressure on the hemorrhage site by the magnetic force between the two magnet rings (the magnetic force between the two magnet rings is present in the first rotation range, and the magnitude of the magnetic force can be changed by rotating the pressing portion in the first rotation range), and can change the amount of medicine on the hemorrhage site by the magnetic force between the two magnet rings (the magnetic force between the two magnet rings is present in the second rotation range of the adjustment portion 30, and the magnitude of the magnetic force can be changed by rotating the pressing portion in the second rotation range). The hemostasis device with the structure can automatically apply medicine to the bleeding part, and the specific process is as follows:
the knob 32 on the adjuster 30 is turned to switch the adjuster 30 from the first rotation range to the second rotation range, the magnetic repulsion force between the first magnet ring 41 and the second magnet ring 42 is switched to the magnetic attraction force, the adjuster 30 is turned to a turning angle in the second rotation range, the turning angle of the adjuster 30 causes the arc-shaped magnet in the first magnet ring 41 and the arc-shaped magnet in the second magnet ring 42 to be opposite in polarity, so that the magnetic attraction force between the first magnet ring 41 and the second magnet ring 42 is maximized, and under the magnetic attraction force of the two, as shown in fig. 1 and 2, the piston 70 moves upward, the piston 70 shrinks the accommodating space 80, the pressure therein increases, then the first check valve 51 is forced to open, the liquid medicine enters the sheath 63 through the first check valve 51, and at the same time, the gas pressure above the liquid medicine in the accommodating space 80 increases and is greater than the external pressure, the second check valve 52 is kept in a closed state, when the liquid medicine entering the housing 63 reaches the amount required for one-time medicine changing, the knob 32 is rotated to switch the regulating part 30 from the second rotation range to the first rotation range, as shown in fig. 3 and 4, the magnetic attraction force between the first magnet ring 41 and the second magnet ring 42 is switched to the magnetic repulsion force, the regulating part 30 is rotated to a rotation angle within the first rotation range, the rotation angle of the regulating part 30 causes the arc-shaped magnet in the first magnet ring 41 to be opposed to the arc-shaped magnet in the second magnet ring 42, so that the magnetic repulsion force between the first magnet ring 41 and the second magnet ring 42 is maximized, the piston 70 moves down under the magnetic repulsion force, the piston 70 increases the accommodating space 80, the pressure in the accommodating space 80 is reduced, the pressure is lower than the external atmospheric pressure and the pressure in the housing 63 (since the inside of the housing 63 is communicated with the external atmosphere through the liquid guide hole 611), thereby, the first check valve 51 is closed, the second check valve 52 is opened, and the external air enters the accommodating space 80 through the first check valve 51 to supplement the volume occupied by the liquid medical agent entering the cover body 63 (when the amount of the liquid medical agent entering the cover body 63 is small, the pressure in the accommodating space 80 may not be reduced below the atmospheric pressure when the piston 70 moves down or after moving down to the lowest position, in this case, both the first check valve 51 and the second check valve 52 are closed). The liquid entering the sheath body 63 enters the hemostatic cotton 62 along the absorbent cotton 612 under the suction action of the absorbent cotton 612, so that the hemostatic cotton 62 is used for applying medicine to the bleeding part.
As can be seen from the above description, when the bleeding part needs to be filled (or replaced), the hemostatic device of the present invention directly rotates the adjustment portion 30 without unfastening the band 200 to move the piston 70 upward, and then the liquid medicine in the receiving space 80 enters the sheath 63 and reaches the bleeding part through the absorbent cotton 612 and the hemostatic cotton 62.
The hemostatic device of the invention has the following advantages when being used for applying medicine to a bleeding part:
1. when the liquid medical agent enters the sheath 63 and the piston 70 is moved down by rotating the knob 32 again for applying a force to the bleeding part, the downward movement of the piston 70 continuously decreases the space between the piston 70 and the pressing head 61, and the pressure in the space increases to force the liquid medical agent therein to rapidly pass through the absorbent cotton 612 and the hemostatic cotton 62 to reach the bleeding part.
2. The process of applying force to the bleeding part by the pressing head 61 and the process of applying medicine to the bleeding part by the liquid medicine are synchronous processes, so that the time for separating the pressing head 61 from the bleeding part due to medicine application is saved.
3. The liquid medicine can be added into the receiving space 80 through the inlet of the second check valve 52 by using an injection tool.
