Description

Dysmenorrhoea therapeutic equipment

Technical Field

The invention relates to the field of medical appliances, in particular to a dysmenorrheal therapeutic apparatus, wherein an IPC main classification number of the dysmenorrheal therapeutic apparatus mainly relates to A61H 39/00.

Background

Dysmenorrhea is one of the most common gynecological symptoms, and refers to those with lower abdominal pain, sagging and distension before and after menstruation or during menstruation, accompanied by soreness of waist or other discomforts, and the symptoms seriously affect the quality of life. The dysmenorrhea is divided into primary dysmenorrhea and secondary dysmenorrhea, wherein the primary dysmenorrhea refers to dysmenorrhea caused by genital organ anergy lesion; secondary dysmenorrhea refers to dysmenorrhea caused by pelvic organic diseases, such as endometriosis and adenomyosis. According to the traditional Chinese medicine, the pathogenesis of dysmenorrhea is mainly caused by the influence of pathogenic factors, so that chong and ren blocking or cold congealing of meridians are caused, qi and blood circulation is not smooth, and the circulation of uterus menstrual blood is blocked, so that 'obstruction causes pain': or the Chong and ren meridians and uterus failing to nourish them are not nourished and become lusterless and painful. The disease location is in Chong and ren meridians and uterus, and changes in qi and blood, which is manifested as pain. It is usually associated with the change of qi and blood during menstruation, which occurs with the menstrual cycle.

The symptoms of lower abdomen or waist pain and general discomfort occurring in the menstrual period and before and after the menstrual period are called dysmenorrhea. Severe dysmenorrhea may be accompanied by nausea, vomiting, cold hands and feet, and even syncope, which seriously affects work and life. The western medicine is mainly treated by analgesics, hormones and operations, but the patients are easy to generate drug resistance to the western medicine, the operation recurrence rate is high, and the dysmenorrhea cannot be radically treated.

In traditional Chinese medicine, the treatment is based on the syndrome differentiation by focusing on the etiology, and different prescriptions are applied according to the etiology, so that the symptoms are fundamentally relieved, and the incidence of dysmenorrhea is reduced. However, because the traditional Chinese medicine is inconvenient to boil and has poor taste, and the traditional Chinese medicine needs to be taken for a long time, many women are reluctant to accept the treatment mode.

A driving gear 121, a rack 122 meshed with the driving gear 121 and a piston 123 arranged at the bottom of the rack 122 are arranged in the buffer cylinder 12 through a driving motor; the drive gear 121 is a half-tooth gear; the cushion cylinder 12 communicates with the hose assembly 2 through a three-stage solenoid valve 124. A heat insulating layer 131 is provided between the high pressure cylinder assembly 11 and the housing 13, and the high pressure cylinder assembly 11 is sealed by a sealing cover 132. A filter screen 111b is arranged in the first-stage high-pressure cavity 111, the filter screen 111b can be used for containing required medicinal materials, and the pretreated liquid medicine can be directly placed in the first-stage high-pressure cavity 111.

The control system comprises a processor module, a signal input module and a signal receiving module. The signal input module comprises a pressure sensor I (not shown in the figure) arranged in the primary high-pressure cavity 111, a temperature sensor I, a pressure sensor II (not shown in the figure) arranged in the secondary high-pressure cavity 112, a pressure sensor III (not shown in the figure) arranged in the buffer cylinder body, a temperature sensor II arranged in the nozzle assembly 22, and a display screen 221 arranged on the outer wall of the nozzle assembly shell.

The receiving module comprises a heating circuit, a first-stage electromagnetic valve 111a, a second-stage electromagnetic valve 112a, a third-stage electromagnetic valve 124 and a driving motor on the buffer cylinder.

The hose assembly 2 comprises a hose 21 communicated with the buffer cylinder through a pipe joint and a three-stage solenoid valve 124, a nozzle assembly 22 arranged at the end part of the hose 21, wherein the nozzle assembly 22 comprises a nozzle shell 13, a spray switch 222 arranged on the shell 13, a cold air bypass pipe 23 and a flow regulating assembly 223 arranged at the output end of the nozzle shell 13. The flow regulating assembly 223 comprises a plurality of vanes 223a and an adjusting ring 223b which are arranged along the circumferential direction, each vane 223a is hinged on the adjusting ring 223b through a fixing column 223e at equal intervals, and the outer side of each vane 223a is limited in a limiting groove 223c on the inner side of the nozzle shell 13 through a limiting column 223 d.

The rack gear 122 and the piston 123 are driven to reciprocate in the cushion cylinder 12 by the driving gear 121 through unidirectional rotation of an output shaft provided to a driving motor (not shown). Thereby adjusting the used volume of the cushion cylinder 12 (the lower region of the piston 123). Assuming that the displacement of the piston in the vertical direction when the gear is at the position in fig. 1 is 0, the gear angle and rack displacement correspondence relationship is as shown in the following table.

TABLE 1 correspondence between gear rotation angle a and rack displacement d

Note: when the rack is positioned at the top, the displacement is Ymax, and the buffer cylinder body has the maximum volume Vmax;

when the rack is positioned at the lowest part, the displacement is-Ymax, and the buffer cylinder body has the minimum volume Vmin.

The working process of cooperation between each cavity and the solenoid valve is detailed by taking the P1 threshold value of 5atm (boiling point of 151.1 ℃) as an example. Meanwhile, the maximum pressure which can be borne by the high-pressure cylinder assembly 11 is 10 atm-15 atm due to the comprehensive consideration of the factors such as safety, manufacturing cost, cylinder volume and cylinder weight (the larger the bearing force is, the thicker the cylinder side wall is). Of course, in order to prolong the service time of the equipment, the threshold value and the bearing capacity of the cylinder body can be correspondingly improved.

For convenience of presentation, the pressure of the first stage high pressure chamber 111 is denoted as P1, the liquid temperature therein is denoted as T1, the gas temperature within the nozzle assembly is denoted as T2, the first stage solenoid valve is denoted as v1, the pressure of the second stage high pressure chamber 112 is denoted as P2, the second stage solenoid valve is denoted as v2, the pressure of the cushion cylinder is denoted as P3, the third stage solenoid valve is denoted as v3, the heating circuit is denoted as H, and the atmospheric pressure is denoted as P0.

TABLE 2 corresponding relationship between signal input module and signal receiving module under different states

State I: p1<5atm, P2< <5atm, P3= P0, and T1<150 ℃, the heating circuit is connected, and v 1-v 3 are closed.

In addition, the protection circuit is arranged on the heating body 113, and no matter in any state, when the threshold value T1 is greater than T1 within a certain range, such as the threshold value T1 is higher than the threshold value T20-50 ℃, the heating circuit stops working when the liquid in the primary high-pressure cavity is not enough, so that the 'dry burning' in the primary high-pressure cavity is avoided, and the service life of components is shortened.

And state II: p1 is approximately equal to 5atm, P2 is less than 5atm, P3= P0, and T1 is approximately equal to 150 ℃, the heating circuit is closed, v1 is opened, v 2-v 3 is closed, and the liquid medicine in the primary high-pressure cavity enters the secondary high-pressure cavity under the action of gravity.

And state III: p1 ≈ 5atm, P2 ≈ 5atm, P3= P0, and when T1 ≈ 150 ℃, v 1-v 3 are closed, and the secondary high-pressure cavity 112 is filled with the liquid medicine.

The second-stage high-pressure chamber 112 is much smaller in volume than the first-stage high-pressure chamber 111, and since there is only a small amount of liquid, the liquid medicine lost each time does not have a significant effect on P1. Upon a sudden pressure drop in the secondary high pressure chamber 112 (in communication with the cushion cylinder 12), all of the liquid in the secondary high pressure chamber 112 is rapidly vaporized without bumping. By arranging the second-stage high-pressure cavity 112, overlarge air pressure change amplitude caused by direct communication between the first-stage high-pressure cavity 111 and the atmosphere can be avoided, and the safety is further improved.

And state IV: v1 is closed, v2 is opened, v3 is closed, the liquid medicine in the secondary high-pressure cavity is rapidly vaporized and the buffer cylinder is filled, and at the moment, P1 is approximately equal to 5atm, and P0< P2= P3<5 atm.

And a state V: when the pressure of P3 reaches the P3 threshold value, v3 is opened, and physiotherapy can be performed by controlling the injection switch 222 and the flow regulating assembly 223.

Set up temperature sensor (not shown in the figure) in the hose assembly 2, press the jet switch 222 of hose assembly 2, tertiary solenoid valve 124 opens, steam gets into hose assembly 2 through buffer cylinder 12, and mix with hose assembly 2's bypass cooling gas, the temperature sensor that sets up in hose assembly 2 detects the temperature of gas in the hose 21, when the temperature reaches the setting value, the valve on the nozzle 22 can be opened and spout steam, and set up red green pilot lamp, when T2 satisfied the setting temperature, then the pilot lamp is green, thereby avoid scalding. By setting the flow rate of the bypass cooling gas (since the P3 threshold is constant, the bypass flow rate control device is the mixer temperature control device), the temperature of the mixed vapor finally discharged from the nozzle 22 can be set.

When the pressure in the hose assembly is reduced along with the use process, v2 and v3 are simultaneously opened to gradually vaporize the liquid medicine in the P2, and in order to avoid the overlarge P2 and P3, the volume of the buffer cylinder body can be adjusted through the driving motor in the buffer cylinder body, and then P2 and P3 are adjusted.

When P2 is smaller than the P2 threshold, v1 is opened, v2 is closed, v3 is opened, the state II and the state III are repeated, and the liquid medicine is filled in the second-level high-pressure cavity again. In order to avoid temporary pressure loss in the hose caused by v2 closing, the driving motor of the buffer cylinder body drives the piston to move to contract the volume of the buffer cylinder body so as to realize the buffer effect, and in the buffer process, the secondary high-pressure cavity is filled with the liquid medicine again, so that the pressure of P3 can be continuously maintained. Therefore, the liquid medicine in the primary high-pressure cavity can be safely and stably converted into steam flow with constant pressure and constant temperature.

Meanwhile, in order to explain the safety of the high-pressure cylinder and the comparison relationship between the heat capacity and the pressure of the liquid medicine, the following table is provided. The production standard for liquefied gas tanks is in accordance with GB17267-1998, up to 2.1MPa (about 20 atm). The high-pressure cylinder body assembly of the embodiment not only has a volume far smaller than that of the liquefied gas tank, but also has relatively small bearing capacity, and completely meets the safety requirements in production and use. It can be seen that for every 1atm increase in the P1 threshold, the amount of heat carried by the same volume of liquid medicine increases by about 10%.

By combining the control method, the whole therapeutic apparatus can be automatically controlled by an embedded programming or programmable processor (the threshold value is automatically set according to different conditions). The operating parameters of P1-P3 and T1-T2 and the working state of H can be output to the display screen in real time through the processor module, so that the use is convenient.
