Description

[0002] An extracorporeal shock wave treatment equipment is generally composed of an impact wave probe and an air source, and the air source provides pulse gas to the impact wave probe, so that the impact wave probe generates an impact wave.

[0003] The existing impact wave treatment equipment mostly relies on a high-pressure gas cylinder to supply gas to the impact wave probe, and before use, the high-pressure gas cylinder needs to be pre-inflated by a compressor. When the impact wave treatment equipment is assembled, a reversing stop valve needs to be arranged between the gas cylinder and the probe, and the reversing frequency of the reversing stop valve is controlled to realize the control of the impact wave frequency.

[0004] When the gas cylinder is used to supply gas, the pressure in the cylinder will decrease as the use time increases, which causes the impact wave intensity to be unable to be maintained consistently for a long time. In particular, for the treatment of shock wave vaginopathy, if a low-intensity and high-frequency treatment strategy is adopted, the treatment time of each treatment is generally more than half an hour, and the impact wave intensity is likely to be high and low during the treatment process. In addition, if the current impact wave intensity is found to be unsatisfactory during the treatment process, the medical staff needs to replace the gas cylinder with higher pressure or use the compressor to increase the pressure in the gas cylinder, which not only is troublesome to operate but also increases the waiting time of the patient.

DETAILED DESCRIPTION

[0028] The specific embodiments of the utility model are described in detail below in combination with the drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the utility model, and are not used to limit the utility model.

[0029] The shock wave gas source generating device of the utility model is described below with reference to the drawings.

[0030] The utility model provides a kind of shock wave gas source generating device, as Figure 1 And Figure 2 As shown in the figure, the shock wave gas source generating device includes compression cylinder 5, pusher assembly 7 and drive assembly.

[0031] Compression cylinder 5 can be double-end cylinder and is provided with first extension rod end 5a and second extension rod end 5b, and further includes compression cavity 5c corresponding to first extension rod end 5a, and further provided with one-way gas inlet channel 5f and gas outlet channel 5d on the cylinder wall of compression cylinder 5, which are communicated with compression cavity 5c, and further provided with pressure relief valve 61 with adjustable pressure relief pressure in gas outlet channel 5d.

[0032] Pusher assembly 7 includes first cam 71 and second cam 72 corresponding to first extension rod end 5a and second extension rod end 5b respectively, and first cam 71 and second cam 72 are used to alternately apply axial thrust to first extension rod end 5a and second extension rod end 5b.

[0033] Drive assembly is used to drive first cam 71 and second cam 72 to rotate synchronously.

[0034] The driving assembly drives the second cam 72 to rotate, the second cam 72 applies a thrust force to the second extending rod end 5b of the piston rod 52, the piston rod 52 is moved towards the extending direction of the first extending rod end 5a, and the movement of the piston rod 52 compresses the gas in the compression cavity 5c. When the piston rod 52 moves to a position, the pressure of the gas in the compression cavity 5c is greater than the opening pressure of the pressure relief valve 61, the pressure relief valve 61 is opened, and at this time, the high-pressure gas in the compression cavity 5c is provided to the outside through the gas outlet channel 5d. After the second cam 72 completes the thrust, the first cam 71 applies a thrust force to the first extending rod end 5a of the piston rod 52, the piston rod 52 is reset and moved towards the extending direction of the second extending rod end 5b, and at this time, the compression cavity 5c is replenished with gas. Through the alternating cooperation of the first cam 71 and the second cam 72, the compression cylinder 5 can stably and continuously generate pulse gas. Due to the presence of the pressure relief valve 61, the pressure of the pulse gas output by the compression cylinder 5 each time can be ensured to be the same, so that the energy intensity of the shock wave generated each time is the same. In addition, medical staff only needs to adjust the pressure relief pre-tightening force of the pre-tightening spring in the pressure relief valve 61 to realize the adjustment of the pulse gas pressure, which is very convenient to adjust.

[0035] Specifically, as shown in Figure 1 and Figure 2 In the embodiment of the utility model, the compression cylinder 5 includes cylinder body 51 and piston rod 52, piston rod 52 is arranged in cylinder body 51, and the two ends of piston rod 52 are first extending rod end 5a and second extending rod end 5b respectively, first extending rod end 5a and second extending rod end 5b extend from the two ends of cylinder body 51 respectively, piston rod 52 divides the inner cavity of cylinder body 51 into intake cavity 5f2 and compression cavity 5c, cylinder wall of cylinder body 51 is respectively equipped with intake port 5f1 and exhaust port 5d1 that communicate with intake cavity 5f2 and compression cavity 5c, piston rod 52 is further equipped with one-way channel 5f3 that unidirectionally communicates from intake cavity 5f2 to compression cavity 5c, one-way channel 5f3 is set as conducting when gas flows from intake cavity 5f2 to compression cavity 5c and reverse cut-off, wherein one-way intake channel 5f is at least composed of intake port 5f1, intake cavity 5f2 and one-way channel 5f3, and gas outlet channel 5d includes exhaust port 5d1.

[0036] When piston rod 52 moves towards the extending direction of first extending rod end 5a, piston rod 52 compresses the gas in compression cavity 5c, and at the same time, intake cavity 5f2 takes in gas through intake port 5f1. When piston rod 52 moves towards the extending direction of second extending rod end 5b to a certain position, the pressure in compression cavity 5c is less than the pressure in intake cavity 5f2, at this time, the gas in intake cavity 5f2 can enter compression cavity 5c through intake port 5f1, intake cavity 5f2 and one-way channel 5f3, thereby realizing the gas replenishment of compression cavity 5c.

[0037] As shown in Figure 2and Figure 3 As shown, in an embodiment of this utility model, the one-way channel 5f3 can be a conical channel disposed on the plug body 521, with one end of the conical channel near the intake chamber 5f2 ( Figure 2 The left end of the cone-shaped channel is a small opening with a smaller cross-sectional area, and the tapered channel is located near the compression chamber 5c at one end. Figure 2 The right end of the cone-shaped channel has a large cross-sectional area, through which a ball and a spring can be installed. A first clamping plate 522 and a second clamping plate 523 can be installed on both sides of the plug body 521. The first clamping plate 522 is located on the side of the plug body 521 closest to the compression chamber 5c. The first clamping plate 522 and the second clamping plate 523 are used to hold the ball within the cone-shaped channel. The spring is positioned between the ball and the first clamping plate 522 to prevent the ball from completely adhering to the first clamping plate 522, which could block the air vents on the first clamping plate 522. When the pressure in the compression chamber 5c is greater than the pressure in the intake chamber 5f2, the ball will move towards the smaller opening of the cone-shaped channel to close it. When the pressure in the compression chamber 5c is less than the pressure in the intake chamber 5f2, the ball will move towards the larger opening of the cone-shaped channel, at which point the cone-shaped channel is open.

By pressing the pre-tightening spring, the conical head end can be kept in the state of cutting off the air outlet channel 5d2. The telescopic pusher 62 is mainly used to adjust the pre-tightening force of the warning spring in order to adjust the pressure relief pressure.

[0040] In this case, the direction of the pressure relief pre-tightening force of the pressure relief valve is opposite to the direction of air outlet at the installation channel, that is, the front of the conical head end is directly opposite the axial direction of the air outlet at the installation channel.
