Technical Field

[0001] The invention belongs to the technical field of pressure-adjusting and flushing, and in particular relates to a pressure-adjusting and flushing device for gynecological clinical use. Background Art

[0002] Gynecological flushing therapy equipment is a medical device used to clean the female reproductive tract; it is mainly used to assist in the treatment of various gynecological diseases. With the help of gynecological flushing therapy equipment, it helps to restore the normal environment of the reproductive tract and promote recovery from the disease.

[0003] Existing gynecological irrigation treatment equipment is pressurized by a water pump, and the pressure needs to be manually adjusted to change the flow rate of the liquid medicine. However, the manual adjustment method is relatively rough, and the flow rate will suddenly become very high and then suddenly become very low. This makes it difficult to make precise and detailed adjustments, or it is difficult to adjust it quickly, which can easily cause discomfort to patients. Therefore, it is also necessary to improve the pressure regulation and liquid control method of gynecological irrigation treatment equipment. Summary of the invention

[0012] A displacement driving mechanism, the displacement driving mechanism is used to drive the adjusting head to slide relative to the first connecting tube and the second connecting tube;

[0013] When the regulating head slides toward the first connecting tube, the pressure of the liquid flowing out of the second connecting tube decreases, and when the regulating head slides away from the first connecting tube, the pressure of the liquid flowing out of the second connecting tube increases.

[0014] In the present technical solution, when flushing treatment is required, the medicine is first stored in a liquid storage tank, and the outlet tube, the flow rate regulating mechanism, and the liquid outlet tube are connected in sequence. The liquid storage tank exports the medicine through the outlet tube at a certain flow rate. The medicine is regulated by the flow rate regulating mechanism and then sprayed out through the liquid outlet tube for patient flushing. When the flow rate of the medicine needs to be increased, the displacement drive mechanism is started to drive the regulating head to slide away from the first connecting tube. During the sliding process of the regulating head, the flow rate of the medicine gradually increases. When the flow rate of the medicine needs to be reduced, the displacement drive mechanism is started to drive the regulating head to slide toward the first connecting tube. During the sliding process of the regulating head, the flow rate of the medicine gradually decreases.

[0015] In the above technical solution, further, the liquid outlet pipe includes a hose and a nozzle, one end of the hose is connected to the second connecting pipe, and the other end of the hose is connected to the nozzle.

[0017] In the above technical solution, further, a plurality of flow diversion channels are provided, and the plurality of flow diversion channels are distributed at intervals along the circumference of the regulating head.

[0018] In the above technical solution, further, the displacement driving mechanism includes:

[0019] A fixing ring, which is arranged on the outer wall of the adjusting head, a guide rod is arranged on one side of the fixing ring, and a threaded hole is arranged on the other side of the fixing ring;

[0020] A guide frame, the guide frame is arranged on the outer wall of the first connecting tube, and the guide rod is slidably connected with the guide frame along the moving direction of the adjusting head;

[0021] A connecting frame, which is arranged on the first connecting pipe or the second connecting pipe;

[0022] A transmission shaft, the transmission shaft is rotatably connected to the connecting frame, and the transmission shaft is provided with an external thread that is threadedly connected to the threaded hole;

[0023] The motor is used to drive the transmission shaft to rotate.

[0024] In the above technical solution, further, a first transmission gear and a second transmission gear are spaced apart in the axial direction on the transmission shaft, and the number of teeth of the first transmission gear is greater than the number of teeth of the second transmission gear; a driving shaft is provided on one side of the transmission shaft, and a first driving gear and a second driving gear are spaced apart in the axial direction on the driving shaft, and the number of teeth of the first driving gear is less than the number of teeth of the second driving gear, and the first driving gear can mesh with the first transmission gear, and the second driving gear can mesh with the second transmission gear;

[0025] The drive shaft is connected to the output shaft of the motor through a slider coupling. When the drive shaft moves in the axial direction, the first drive gear and the first transmission gear can switch between engagement and disengagement, and the second drive gear and the second transmission gear can switch between engagement and disengagement.

[0026] In the above technical solution, further, an extension plate is provided on the drive shaft, the drive shaft can rotate on the extension plate, the drive shaft cannot move axially relative to the extension plate, and a cylinder is provided on one side of the motor for driving the extension plate to move axially along the drive shaft.

[0027] In the above technical solution, further, the step groove is in the shape of multiple steps, the outer contour of the adjusting head near one end of the step groove is in the shape of multiple steps, and two groups of flow channels are arranged at intervals on the outer walls adjacent to each other along the axial direction of the adjusting head near one end of the step groove. When the adjusting head moves toward the first connecting pipe to open one group of flow channels, the other group of flow channels can still be blocked by the side wall of the step groove, and when the adjusting head continues to move toward the first connecting pipe, the two groups of flow channels can be opened at the same time.

[0028] The present invention also discloses a method for using the pressure flushing device, which comprises the following steps:

[0029] X1. Increase flow rate: The motor drives the transmission shaft to rotate, and the transmission shaft drives the fixed ring to move away from the outlet pipe, and the fixed ring drives the regulating head to move away from the first connecting pipe. During this process, the distance between the branch channel and the side wall of the step groove decreases, so that the pressure of the liquid in the main channel increases, thereby increasing the flow rate of the liquid flowing out of the second connecting pipe;

[0030] X2. Reduce flow rate: The motor drives the transmission shaft to rotate, and the transmission shaft drives the fixed ring to move toward the outlet pipe, and the fixed ring drives the regulating head to move toward the first connecting pipe. During this process, the distance between the branch channel and the side wall of the step groove increases, so that the pressure of the liquid in the main channel is reduced, thereby reducing the flow rate of the liquid flowing out of the second connecting pipe;

[0031] X3, coarse adjustment: control the axial displacement of the drive shaft, so that the first drive gear is separated from the first transmission gear, and the second drive gear is meshed with the second transmission gear. At this time, when the motor drives the drive shaft to rotate, the drive shaft accelerates and drives the transmission shaft to rotate. In this process, the transmission shaft will drive the fixing ring to move rapidly along the axial direction at a faster speed, thereby driving the adjustment head to move rapidly along the axial direction, thereby rapidly increasing the flow rate of the liquid or rapidly reducing the flow rate of the liquid;

[0032] X4. Fine adjustment: Control the axial displacement of the drive shaft so that the first drive gear meshes with the first transmission gear and the second drive gear separates from the second transmission gear. At this time, when the motor drives the drive shaft to rotate, the drive shaft decelerates and drives the transmission shaft to rotate. In this process, the transmission shaft will drive the fixing ring to move slowly axially at a slower speed, thereby driving the adjusting head to move slowly axially, thereby slowly increasing the flow rate of the liquid or slowly decreasing the flow rate of the liquid.

[0033] The beneficial effects of the present invention are:

[0034] 1. The flow rate of the liquid medicine discharged from the liquid storage tank is adjusted by a flow rate regulating mechanism. Specifically, the displacement driving mechanism is used to drive the regulating head to slide sealedly between the first connecting tube and the second connecting tube, so that the flow rate of the liquid medicine is gradually increased or decreased, thereby avoiding sudden changes in the flow rate of the liquid medicine causing discomfort to the patient.

[0035] 2. By setting a step groove in the second connecting tube, setting a main channel connecting the two ends in the regulating head, designing the outer contour of one end of the regulating head to match the step groove, and opening a branch channel connecting the main channel at the end of the regulating head, the regulating head is driven to slide between the first connecting tube and the second connecting tube to adjust the gap between the branch channel and the side wall of the step groove, thereby adjusting the pressure of the medicine in the main channel, and then adjusting the flow rate of the medicine, which is very convenient.

[0036] 3. By designing multiple branch channels and distributing the multiple branch channels at intervals along the circumference of the regulating head, when the liquid medicine passes through the branch channels to reduce the pressure of the liquid medicine in the main channel, the force on the regulating head in the circumferential direction is more uniform, making it less likely to shift the position, thereby ensuring the sealing of the flow rate regulating mechanism.

[0037] 4. By designing the displacement drive mechanism to be a combination of a fixed ring, a guide rod, a threaded hole, a guide frame, a connecting frame, a transmission shaft, and a motor, and starting the motor to drive the transmission shaft to rotate, the fixed ring can be driven to move axially, thereby driving the adjusting head to slide between the first connecting tube and the second connecting tube to adjust the flow rate of the liquid medicine. The user does not need to manually drive continuously, which is more labor-saving and the movement speed of the adjusting head can also be more uniform.

[0038] 5. The first transmission gear and the second transmission gear are arranged on the transmission shaft, and the driving shaft, the first driving gear, the second driving gear and the sliding coupling are arranged to cooperate to transmit the driving force of the motor to the transmission shaft, and the transmission ratio when the first transmission gear is meshed with the first driving gear is different from the transmission ratio when the second transmission gear is meshed with the second driving gear. In this way, by switching the axial position of the driving shaft, the same output of the motor can be used to differentially drive the transmission shaft, thereby realizing high-speed coarse adjustment and low-speed fine adjustment of the flow rate of the liquid medicine, which is convenient for the user to quickly adjust the flow rate to the right position.

[0056] Example 1

[0057] like Figure 1-Figure 2 As shown, the embodiment of the present application provides a pressure-regulated flushing device for gynecological clinical use, comprising: a liquid storage tank 1, a guide tube 2, a liquid outlet tube 3, a flow rate regulating mechanism,

[0058] The liquid storage tank 1 can store liquid. The liquid in this embodiment specifically refers to gynecological flushing liquid, such as physiological saline, potassium permanganate solution diluted in proportion, metronidazole solution, etc. The liquid storage tank 1 is provided with a derivation pipe 2, which is connected to the liquid storage tank 1 through a pump or other pressure structure, so that the liquid in the liquid storage tank 1 can be discharged from the derivation pipe 2 at a fixed flow rate;

[0059] The liquid outlet pipe 3 is used to spray the liquid medicine discharged from the liquid storage tank 1; the liquid outlet pipe 3 is connected to the outlet pipe 2 through a flow rate regulating mechanism, and the flow rate regulating mechanism can regulate the flow rate of the liquid medicine discharged from the outlet pipe 2, and the liquid outlet pipe 3 discharges the liquid medicine after the flow rate regulation;

[0060] In this embodiment, the flow rate regulating mechanism includes: a first connecting pipe 4, a second connecting pipe 5, a regulating head 6,

[0061] One end of the first connecting pipe 4 is connected to the outlet pipe 2;

[0062] One end of the second connecting tube 5 is connected to the liquid outlet tube 3, and the second connecting tube 5 is connected to the first connecting tube 4 via a connecting piece (not shown in the figure) so that the second connecting tube 5 is fixed relative to the first connecting tube 4;

[0063] The regulating head 6 is arranged between the first connecting tube 4 and the second connecting tube 5, one end of the regulating head 6 is sealed and slidably connected to the end of the first connecting tube 4 away from the outlet tube 2, and the other end of the regulating head 6 is sealed and slidably connected to the end of the second connecting tube 5 away from the liquid outlet tube 3;

[0064] The displacement driving mechanism 7 is used to drive the regulating head 6 to slide relative to the first connecting tube 4 and the second connecting tube 5; when the regulating head 6 slides toward the first connecting tube 4, the pressure of the liquid medicine flowing out of the second connecting tube 5 decreases, and when the regulating head 6 slides away from the first connecting tube 4, the pressure of the liquid medicine flowing out of the second connecting tube 5 increases;

[0065] As a preferred embodiment of this embodiment, please refer to Figure 2 The liquid outlet pipe 3 includes a hose 301 and a nozzle 302. One end of the hose 301 is connected to the second connecting pipe 5, and the other end of the hose 301 is connected to the nozzle 302. The end of the hose 301 close to the second connecting pipe 5 is rigid and used for connection and fixation. The hose 301 is elastic as a whole to facilitate the movement of the nozzle 302.

[0066] In this embodiment, when flushing treatment is required, the medicine is first stored in the liquid storage tank 1, and the outlet pipe 2, the flow rate regulating mechanism, and the liquid outlet pipe 3 are connected in sequence. The liquid storage tank 1 guides the medicine through the outlet pipe 2 at a certain flow rate. The medicine is regulated by the flow rate regulating mechanism and then sprayed out through the liquid outlet pipe 3 for patient flushing. When the flow rate of the medicine needs to be increased, the displacement driving mechanism 7 is started to drive the regulating head 6 to slide away from the first connecting pipe 4. During the sliding process of the regulating head 6, the pressure of the medicine increases, thereby gradually increasing the flow rate. When the flow rate of the medicine needs to be reduced, the displacement driving mechanism 7 is started to drive the regulating head 6 to slide toward the first connecting pipe 4. During the sliding process of the regulating head 6, the pressure of the medicine decreases, thereby gradually decreasing the flow rate. In this way, the flow rate of the medicine gradually increases or decreases, which can avoid sudden changes in the flow rate of the medicine and cause discomfort to the patient.

[0067] Example 2

[0068] This embodiment provides a pressure-regulated flushing device for gynecological clinical use, which, in addition to the technical solutions of the above embodiments, also discloses a structure of a flow rate regulating mechanism;

[0069] In this embodiment, please refer to Figure 7 or Figure 8 A step groove 501 is provided on the inner wall of one end of the second connecting pipe 5 close to the liquid outlet pipe 3. From the axial cross section of the second connecting pipe 5, the step groove 501 includes at least one inclined inner wall at an inclined angle to the axis and one parallel inner wall 5012 parallel to the axis. Figure 6, the outer contour of the end of the regulating head 6 close to the step groove 501 is adapted to the step groove 501, and a main flow channel 601 connecting the two ends of the regulating head 6 is opened in the regulating head 6, the inner diameter of the main flow channel 601 close to the end of the liquid outlet pipe 3 is smaller than the inner diameter of the other end, and the diameter of the main flow channel 601 close to the end of the liquid outlet pipe 3 is smaller than the inner diameter of the end of the second connecting pipe 5 close to the liquid outlet pipe 3; a branch flow channel 602 connecting the main flow channel 601 is provided at a position opposite to the inclined inner wall of the step groove 501 at the end of the regulating head 6, and the inclined inner wall on the step groove 501 can block the branch flow channel 602;

[0070] Figure 7 The schematic diagram shown is that the inclined inner wall of the step groove 501 blocks the branch channel 602. At this time, the liquid medicine in the main channel 601 can only flow out from the end of the main channel 601 close to the liquid outlet pipe 3. At this time, the liquid medicine in the main channel 601 has a greater outflow resistance and a greater pressure, thereby increasing the flow rate of the liquid medicine.

[0071] Figure 8 The schematic diagram shown is a diagram showing a gap between the inclined inner wall of the step groove 501 and the branch channel 602. At this time, the liquid medicine in the main channel 601 can still flow out from the branch channel 602, reducing the outflow pressure of the liquid medicine in the main channel 601, thereby reducing the flow rate of the liquid medicine.

[0072] exist Figure 7 Adjust the position of the head 6 to Figure 8 During the movement of the middle regulating head 6, the gap between the inclined inner wall of the step groove 501 and the flow channel 602 gradually increases. Before the flow channel 602 is completely separated from the inclined inner wall of the step groove 501, the pressure of the medicine in the main flow channel 601 gradually decreases, that is, the flow rate of the medicine gradually decreases.

[0073] exist Figure 8 Adjust the position of the head 6 to Figure 7 During the movement of the middle regulating head 6, the gap between the inclined inner wall of the step groove 501 and the branch channel 602 gradually decreases. After the branch channel 602 contacts the inclined inner wall of the step groove 501 at the opening, the pressure of the medicine in the main channel 601 gradually increases, that is, the flow rate of the medicine gradually increases.

[0074] As a preference of this embodiment, a plurality of branch channels 602 are provided, and the plurality of branch channels 602 are distributed at intervals along the circumference of the regulating head 6. In this way, when the medicine liquid passes through the branch channels 602 to reduce the pressure of the medicine liquid in the main channel 601, the force on the regulating head 6 in the circumferential direction is relatively uniform, making it less likely to shift the position, thereby ensuring the sealing of the flow rate regulating mechanism.

[0075] Example 3

[0076] This embodiment provides a pressure-regulated flushing device for gynecological clinical use. In addition to the technical solutions of the above embodiments, a structure of a displacement drive mechanism 7 is also disclosed.

[0077] In this embodiment, Figure 3-Figure 4 As shown, the displacement driving mechanism 7 includes: a fixing ring 701, a guide frame 704, a connecting frame 705, a transmission shaft 706, and a motor 707.

[0078] The fixing ring 701 is arranged on the outer wall of the adjusting head 6. When the fixing ring 701 moves axially, it will bring the adjusting head 6 to move axially. A guide rod 702 is arranged on one side of the fixing ring 701. Here, multiple guide rods 702 can be arranged in parallel. A threaded hole 703 is arranged on the other side of the fixing ring 701.

[0079] The guide frame 704 is arranged on the outer wall of the first connecting tube 4, and the guide rod 702 is slidably connected with the guide frame 704 along the moving direction of the adjusting head 6. In this embodiment, the guide frame 704 can also be arranged on the outer wall of the second connecting tube 5. The guide rod 702 cooperates with the guide frame 704 to limit and guide the movement of the fixing ring 701, so as to ensure that the fixing ring 701 moves along the axial direction;

[0080] The connecting frame 705 is arranged on the first connecting pipe 4 or the second connecting pipe 5;

[0081] The transmission shaft 706 is rotatably connected to the connecting frame 705. In order to ensure the stability of the transmission shaft 706, the transmission shaft 706 and the connecting frame 705 have at least two connection points. The transmission shaft 706 is provided with an external thread that is threadedly connected to the threaded hole 703.

[0082] The motor 707 is used to drive the transmission shaft 706 to rotate;

[0083] In this embodiment, the transmission shaft 706 is driven to rotate by the motor 707, and the transmission shaft 706 drives the fixed ring 701 to move axially through threaded transmission, and the fixed ring 701 moves axially with the adjusting head 6, thereby adjusting the flow rate of the liquid medicine; by changing the rotation direction of the output shaft of the motor 707, the transmission shaft 706 can be driven to change the rotation direction, thereby changing the moving direction of the adjusting head 6; in this way, the user does not need to manually drive continuously, which is more labor-saving, and the moving speed of the adjusting head 6 can also be more uniform.

[0084] Example 4

[0085] This embodiment provides a pressure-regulated flushing device for gynecological clinical use. In addition to the technical solutions of the above embodiments, the displacement drive mechanism 7 is optimized.

[0086] In this embodiment, please refer to Figure 5, a first transmission gear 801 and a second transmission gear 802 are axially spaced apart on the transmission shaft 706, the first transmission gear 801 and the second transmission gear 802 are coaxially distributed and coaxial with the transmission shaft 706, the first transmission gear 801 and the second transmission gear 802 will drive the transmission shaft 706 to rotate when they rotate, and the number of teeth of the first transmission gear 801 is greater than the number of teeth of the second transmission gear 802; a driving shaft 803 is provided on one side of the transmission shaft 706, and a first driving gear 804 and a second driving gear 805 are axially spaced apart on the driving shaft 803, the first driving gear 804 and the second driving gear 805 are coaxially distributed and coaxial with the driving shaft 803, when the driving shaft 803 rotates, the first driving gear 804 and the second driving gear 805 will be driven to rotate, the number of teeth of the first driving gear 804 is less than the number of teeth of the second driving gear 805, the first driving gear 804 can mesh with the first transmission gear 801, and the second driving gear 805 can mesh with the second transmission gear 802;

[0087] The drive shaft 803 is connected to the output shaft of the motor 707 via a slider coupling 806. The slider coupling allows the drive shaft 803 to have a certain displacement in the axial direction relative to the output shaft of the motor 707. When the drive shaft 803 moves in the axial direction, the first drive gear 804 and the first transmission gear 801 can switch between meshing and separation, and the second drive gear 805 and the second transmission gear 802 can switch between meshing and separation.

[0088] In this embodiment, when the first driving gear 804 is meshed with the first transmission gear 801, the second driving gear 805 is separated from the second transmission gear 802, and the transmission ratio between the first driving gear 804 and the first transmission gear 801 is large. At this time, the rotation speed of the transmission shaft 706 is lower than the rotation speed of the driving shaft 803, which is equivalent to the motor 707 driving the transmission shaft 706 at a reduced speed, so that the speed of the regulating head 6 moving along the axial direction is slowed down, and the flow rate of the liquid medicine can be adjusted more precisely;

[0089] When the second drive gear 805 is meshed with the second transmission gear 802, the first drive gear 804 is separated from the first transmission gear 801, and the transmission ratio between the second drive gear 805 and the second transmission gear 802 is small. At this time, the rotation speed of the transmission shaft 706 is higher than the rotation speed of the drive shaft 803, which is equivalent to the motor 707 driving the transmission shaft 706 at an increased speed. In this way, the speed of the adjusting head 6 moving along the axial direction becomes faster, and the flow rate of the medicine liquid can be quickly adjusted, so that the medicine liquid can be adjusted to the required flow rate.

[0090] In this embodiment, please refer to Figure 5An extension plate 901 is provided on the driving shaft 803, and a limiting structure is provided on the driving shaft 803 and on both sides of the extension plate 901. The limiting structure can limit the axial movement of the extension plate 901 on the driving shaft 803, so that the driving shaft 803 can only rotate on the extension plate 901, and a cylinder 902 is provided on one side of the motor 707 for driving the extension plate 901 to move axially along the driving shaft 803; the axial position of the driving shaft 803 can be adjusted by driving the cylinder 902, thereby realizing the switching of the transmission shaft 706 between the deceleration drive and the speed increase drive.

[0091] In this embodiment, by switching the axial position of the drive shaft 803, the same output of the motor 707 can be used to differentially drive the transmission shaft 706, thereby achieving high-speed coarse adjustment and low-speed fine adjustment of the flow rate of the liquid medicine, making it convenient for the user to quickly adjust the flow rate.

[0092] Example 5

[0093] This embodiment provides a pressure-adjusting and flushing device for gynecological clinical use. In addition to the technical solutions of the above embodiments, the cooperation between the regulating head 6 and the second connecting tube 5 is optimized.

[0094] In this embodiment, please refer to Fig. 9 or Fig.10 or Fig.11 The step groove 501 is in a multi-step shape. From the axial cross section of the second connecting pipe 5, the step groove 501 includes at least two inclined inner walls that are inclined at an angle to the axis and a parallel inner wall 5012 that is parallel to the axis. The parallel inner wall 5012 is located between two adjacent inclined inner walls. In this embodiment, two inclined inner walls and one parallel inner wall 5012 are taken as an example. The two inclined inner walls are defined as a first inclined inner wall 5011 and a second inclined inner wall 5013 according to the distance between the two inclined inner walls and the liquid outlet pipe 3 from near to far.

[0095] Correspondingly, the outer contour of the end of the regulating head 6 close to the step groove 501 is in a multi-stepped shape. In this embodiment, the end of the regulating head 6 close to the step groove 501 includes two inclined outer walls and a parallel outer wall 604. The two inclined outer walls are defined as a first inclined outer wall 603 and a second inclined outer wall 605 from near to far according to the spacing between the two inclined outer walls and the liquid outlet pipe 3. Two groups of flow channels 602 are arranged at intervals at the outer walls adjacent to each other in the axial direction of the regulating head 6 at the end of the regulating head 6 close to the step groove 501. One group of flow channels 602 is arranged on the first inclined outer wall 603, and the other group of flow channels 602 is arranged on the parallel outer wall 604.

[0096] See also Fig. 9 When the regulating head 6 is located at the minimum distance from the liquid outlet pipe 3, the two component flow channels 602 are blocked by the first inclined inner wall 5011 and the parallel inner wall 5012 respectively; please refer to Fig.10 When the regulating head 6 moves toward the first connecting pipe 4 to open one group of flow channels 602, the other group of flow channels 602 can still be blocked by the parallel inner wall 5012. Fig.11 When the regulating head 6 continues to move toward the first connecting pipe 4, the two components of the flow channels 602 can be opened simultaneously;

[0097] The cooperation between the second inclined inner wall 5013 and the second inclined outer wall 605 is mainly to enable a gap to appear between the parallel outer wall 604 and the inner wall of the second connecting tube 5, so that the branch channel 602 on the parallel outer wall 604 can be opened with the movement of the regulating head 6; it should be noted that when the branch channel 602 on the parallel outer wall 604 is just opened, the liquid medicine flowing out of the branch channel 602 will not flow out directly from the second connecting tube 5, but will be temporarily stored in the area between the second inclined inner wall 5013 and the second inclined outer wall 605, because at this time the parallel outer wall 604 is not completely separated from the parallel inner wall 5012; when the parallel outer wall 604 is completely separated from the parallel inner wall 5012, as the gap between the first inclined outer wall 603 and the second inclined inner wall 5013 increases, the liquid medicine between the second inclined inner wall 5013 and the second inclined outer wall 605 will flow out from the second connecting tube 5; please refer to Fig. 9 In this embodiment, the distance between the second inclined inner wall 5013 and the second inclined outer wall 605 is relatively small. In actual use, the distance between the second inclined inner wall 5013 and the second inclined outer wall 605 may be increased as needed.

[0098] In this embodiment, since a group of flow channels 602 are additionally provided in the axial direction of the regulating head 6, the coordination of the two groups of flow channels 602 enables the adjustable range of the flow rate of the liquid medicine to be larger and the applicable range to be wider.

[0099] Example 6

[0100] This embodiment discloses a method for using a pressure-regulated flushing device for gynecological clinical use. The method is suitable for the pressure-regulated flushing device in the above embodiment. The method includes the following steps:

[0101] X1. Increase flow rate: The motor 707 drives the transmission shaft 706 to rotate, and the transmission shaft 706 drives the fixing ring 701 to move away from the outlet pipe 2, and the fixing ring 701 drives the regulating head 6 to move away from the first connecting pipe 4. During this process, the distance between the branch channel 602 and the side wall of the step groove 501 is reduced, so that the pressure of the liquid in the main channel 601 is increased, thereby increasing the flow rate of the liquid flowing out of the second connecting pipe 5;

[0102] X2. Reduce flow rate: The motor 707 drives the transmission shaft 706 to rotate, and the transmission shaft 706 drives the fixing ring 701 to move toward the direction close to the outlet pipe 2, and the fixing ring 701 drives the regulating head 6 to move toward the direction close to the first connecting pipe 4. In this process, the distance between the branch channel 602 and the side wall of the step groove 501 increases, so that the pressure of the liquid in the main channel 601 is reduced, thereby reducing the flow rate of the liquid flowing out of the second connecting pipe 5;

[0103] X3, coarse adjustment: control the drive shaft 803 to undergo axial displacement, so that the first drive gear 804 is separated from the first transmission gear 801, and the second drive gear 805 is meshed with the second transmission gear 802. At this time, when the motor 707 drives the drive shaft 803 to rotate, the drive shaft 803 accelerates and drives the transmission shaft 706 to rotate. During this process, the transmission shaft 706 drives the fixing ring 701 to move rapidly along the axial direction at a faster speed, thereby driving the regulating head 6 to move rapidly along the axial direction, thereby rapidly increasing the flow rate of the liquid or rapidly reducing the flow rate of the liquid;

[0104] X4. Fine adjustment: control the drive shaft 803 to undergo axial displacement, so that the first drive gear 804 meshes with the first transmission gear 801, and the second drive gear 805 separates from the second transmission gear 802. At this time, when the motor 707 drives the drive shaft 803 to rotate, the drive shaft 803 decelerates and drives the transmission shaft 706 to rotate. During this process, the transmission shaft 706 will drive the fixing ring 701 to move slowly axially at a slower speed, thereby driving the adjusting head 6 to move slowly axially, thereby slowly increasing the flow rate of the liquid or slowly decreasing the flow rate of the liquid.

[0105] Through the combination of the gynecological clinical pressure-regulating flushing equipment and the usage method of this embodiment, the flow rate of the medicinal solution can be adjusted at a relatively uniform speed, making the patient more comfortable during cleaning. At the same time, the flow rate of the medicinal solution can be roughly and finely adjusted, so that it can be quickly adjusted to the required flow rate to meet the different usage requirements of users.

[0106] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present application, ordinary technicians in this field can also make many forms without departing from the purpose of the present application and the scope of protection of the claims, all of which are within the protection of the present application.

During this process, the transmission shaft (706) drives the fixing ring (701) to move rapidly in the axial direction at a relatively high speed, thereby driving the regulating head (6) to move rapidly in the axial direction, thereby rapidly increasing the flow rate of the liquid or rapidly reducing the flow rate of the liquid; X4.

During this process, the transmission shaft (706) drives the fixing ring (701) to move slowly along the axial direction at a slower speed, thereby driving the regulating head (6) to move slowly along the axial direction, thereby slowly increasing the flow rate of the liquid or slowly decreasing the flow rate of the liquid.
