Description

Technical Field

[0001] The present invention relates to the field of obstetric medical devices, and particularly to a cleaning device and method for obstetric delivery. Background Technique

[0002] After childbirth, if there is a large amount of placenta and fetal membrane tissue residue in the uterine cavity of the parturient, it is usually necessary to perform uterine curettage on the parturient. Uterine curettage is to send a device into the uterine cavity of the parturient by a doctor, scrape the residual placenta, fetal membrane and other tissues, and clean these turbid liquids and attachments out of the uterus.

[0003] In the patent with the publication number CN212996720U, a uterine curettage glove device is disclosed. The device can wear the glove body on the hand of medical staff, and use the convex points on the glove body to scrape and clean the decidua in the uterus, etc. After uterine curettage, the thumb and index finger are used to guide the suction tube on the glove, connect the negative pressure suction device, and suck out the blood and decidua in the uterus.

[0004] Although the above device can remove turbid substances such as decidua in the uterus, when wearing a glove on the hand and using the convex points on the glove to scrape the inside of the uterus, first, the fingers need to apply a large force to the uterine wall to press the convex points on the glove against the uterine wall, and then the fingers need to move quickly on the uterine wall to form a rapid friction effect between the convex points and the uterine wall, so as to clean the attachments from the surface of the uterine wall. In this process, while the convex points clean the attachments by friction, they are also likely to cause damage to the uterine wall, resulting in problems such as bleeding of the uterine wall; moreover, when using the suction tube and connecting the negative pressure suction device to absorb turbid substances, it is easy to occur that the suction tube sucks the uterine wall and causes damage to the uterine wall under negative pressure suction. For this reason, we propose a cleaning device and method for obstetric delivery. Summary of the Invention

Mounting seats are respectively fixedly arranged at both ends of the U-shaped frame. The mounting frame is fixedly arranged inside the two mounting seats. The screw rod is movably connected to the two mounting seats respectively.

[0010] Preferably, the discharge component further includes an axle ring, a planetary gear set, a connecting disk, a positioning seat, and a driving motor arranged on one side inside the aggregate pipe. The axle ring is fixedly connected to the aggregate pipe. The connecting disk is located between the planetary gear set and the axle ring.

[0011] Preferably, an inner hole is formed inside one side of the U-shaped frame, a discharge port is formed inside one of the mounting seats, the turbid liquid conveyed by the screw rod enters the inner hole through the discharge port, a sewage discharge hole penetrating through the grip rod is formed in the middle of the U-shaped frame, a connecting pipe communicating the inner hole and the sewage discharge hole is fixedly arranged inside the U-shaped frame, and the feeding end of the negative pressure assembly is connected to the end of the grip rod and communicated with the sewage discharge hole.

[0012] Preferably, the negative pressure assembly includes a first flexible pipe fixedly connected to the grip rod, a gas-liquid separator fixedly connected to the discharge end of the first flexible pipe, a second flexible pipe fixedly installed at the gas outlet end of the gas-liquid separator, and a negative pressure pump fixedly connected to the gas outlet end of the second flexible pipe.

The air filter filters the air entering the inside of the gas treatment tank, and the air heater detects the temperature of the air flow entering the inside of the gas treatment tank and heats it.

[0015] An obstetric delivery cleaning method includes the following steps: S1. First, hold the holding assembly by hand and send the front part of the holding assembly into the uterus of the parturient. Press the arc-shaped scraping rod against the inner wall of the uterus of the parturient and scrape. The turbid liquid scraped out adheres to the surface of the arc-shaped scraping rod. When the pressure of the arc-shaped scraping rod on the inner wall of the uterus of the parturient is too high, the arc-shaped scraping rod deforms itself. S2. Then, use the negative pressure assembly to generate negative pressure in each side groove. When the intake assembly passes by the arc-shaped scraping rod with turbid liquid attached, the turbid liquid is sucked away. When the intake assembly passes by the arc-shaped scraping rod touching the inner wall of the uterus, the supporting plate supports the arc-shaped scraping rod. When the scraping plate touches the arc-shaped scraping rod, it does not contact the inner wall of the uterus. During the rotation, the scraping plate cooperates with the suction of the air flow to take away the stubborn attachments adhering to the inner wall of the uterus when passing through the arc-shaped scraping rod. When the supporting plate passes through the arc-shaped scraping rod, the large-sized attachments adhering to the surface of the arc-shaped scraping rod are divided into small-sized ones, and the attachments are sucked into the inside of the side groove. S3. The turbid liquid and the attachments enter the aggregate pipe through the through port, and the screw rod conveys the turbid liquid and the attachments to the negative pressure assembly.

[0016] The present invention has the following beneficial effects: 1. In the present invention, when the pressure of the arc-shaped scraping rod on the inner wall of the parturient's uterus is too high, the rod deforms itself to reduce the damage to the inner wall of the parturient's uterus. When the arc-shaped scraping rod undergoes a large deformation, the resistance it encounters during scraping on the inner wall of the uterus will increase significantly. The doctor can then judge the pressing degree of the arc-shaped scraping rod on the parturient's uterus based on the resistance during the scraping process, and timely reduce the pressing force. Therefore, the setting of the arc-shaped scraping rod facilitates the effective protection of the parturient's uterus and also facilitates the safe operation of the doctor.

[0017] 2. In the present invention, when the pressing plate passes over the arc-shaped scraping rod, it supports the arc-shaped scraping rod, facilitating the restoration of the arc-shaped scraping rod in the case of deformation, enabling the scraping plate to just pass through the arc-shaped scraping rod without being blocked by the deformed arc-shaped scraping rod. When the scraping plate just passes through the arc-shaped scraping rod, it fits with the surface of the arc-shaped scraping rod, scraping off the attachments and turbid liquids on the surface of the arc-shaped scraping rod.

[0018] 3. In the present invention, when the pressing plate supports the arc-shaped scraping rod, the pressure of the arc-shaped scraping rod on the inner wall of the uterus will increase significantly, and the resistance received by the arc-shaped scraping rod will also increase significantly. The doctor can judge the magnitude of the pressure of the arc-shaped scraping rod on the inner wall of the uterus based on this situation and timely reduce the pressure. When the pressure of the arc-shaped scraping rod on the uterus is relatively large, it will entangle large attachments on the inner surface of the uterus. During the process of the pressing plate supporting the arc-shaped scraping rod, the attachments wrapped around the surface of the arc-shaped scraping rod will be cut open, facilitating the cutting of large attachments into small pieces, making it easier for the scraping plate to scrape off the attachments on the surface of the uterus under the action of air flow, solving the problem that large-sized attachments have high viscosity and are difficult to remove due to adhesion to the surface of the uterus.

[0019] 4. In the present invention, the conveying function of the spiral rod can quickly discharge the internal turbid liquid and attachments from the device, preventing the turbid liquid and attachments in multiple intake components from aggregating and adhering inside the collecting pipe after entering the collecting pipe, so that the turbid liquid and attachments inside the collecting pipe can be discharged in time.

[0020] 5. In the present invention, the spiral rod will generate slight vibrations during operation. These vibrations will cause slight changes in the pressure of the arc-shaped scraping rod on the surface of the uterus. The doctor can clearly sense the amplitude of these changes during use. When the doctor presses the arc-shaped scraping rod against the surface of the inner wall of the uterus with a large pressure, the amplitude of the vibrations generated by the operation of the spiral rod will decrease significantly, enabling the doctor to also judge the pressure of the arc-shaped scraping rod on the inner wall of the uterus based on the vibration situation of the device and timely reduce the force when the pressure is too high. Therefore, it also enables the doctor to better use this device to clean the uterus of pregnant women without causing harm to the uterus.

[0021] 6. In the present invention, the arc-shaped scraping rod is attached to the inner wall of the parturient's uterus and gently scraped to scrape the attachments and turbid liquid inside the uterus. The attachments are further scratched by the scraping plate, and the attachments are scraped off from the inner wall of the uterus, so that the arc-shaped scraping rod does not need to apply a large pressure to the uterus, nor does it need to quickly rub against the inner wall of the uterus to remove the attachments on the surface of the uterus, avoiding the problem of uterine injury caused by rapid friction. By separating the inner wall of the uterus and the scraping plate with the arc-shaped scraping rod, the problem that the entrance of the side groove is covered by the inner wall of the uterus is avoided, and the problem that the side groove sucks the inner wall of the uterus and causes damage to the inner wall of the uterus is solved.

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention. Embodiment

[0026] Please refer to Figure 1 - Figure 12 As shown, a cleaning device for obstetric delivery includes a holding assembly 4 and a negative pressure assembly 6. One end of the holding assembly 4 is fixedly connected to a mounting frame 1 inside. A plurality of arc-shaped scraping rods 2 are fixedly installed inside the mounting frame 1. A cleaning assembly is arranged inside the mounting frame 1 and the arc-shaped scraping rods 2. A discharge assembly 5 is arranged inside the cleaning assembly. The cleaning assembly is communicated with the negative pressure assembly 6 through the discharge assembly 5; the plurality of arc-shaped scraping rods 2 are evenly spaced on the mounting frame 1, and the arc-shaped scraping rods 2 are deformable elastic structures and have strong recovery ability when deformed. When the pressure of the arc-shaped scraping rod 2 pressing on the inner wall of the parturient's uterus is too large, it will deform itself to reduce the damage to the inner wall of the parturient's uterus. When the arc-shaped scraping rod 2 undergoes a large deformation, the resistance encountered by the arc-shaped scraping rod 2 when scraping on the inner wall of the uterus will increase significantly. The doctor can judge the pressing degree of the arc-shaped scraping rod 2 on the parturient's uterus according to the resistance during the scraping process, and reduce the pressing force in time. Therefore, the setting of the arc-shaped scraping rod 2 is convenient for effectively protecting the parturient's uterus and also convenient for the doctor's safe operation.

[0027] The cleaning component is composed of a plurality of intake components 3. The plurality of intake components 3 are distributed in a circumferential array, and two adjacent intake components 3 are closely connected. The intake component 3 includes a diversion seat 31, a collection seat 32 fixedly arranged on one side of the diversion seat 31, a scraping plate 33 fixedly arranged on the side surface of the collection seat 32, and a pressing plate 34 fixedly arranged on one side of the scraping plate 33. The pressing plate 34 is fixedly connected to the collection seat 32. When the pressing plate 34 and the scraping plate 33 pass by the arc-shaped scraping rod 2, they are both in contact with the arc-shaped scraping rod 2. A side groove 22 is formed on the surface of the collection seat 32. The side groove 22 is located between the pressing plate 34 and the collection seat 32, and the pressing plate 34 is located at the entrance of the side groove 22. In this component, the diversion seat 31 is in close contact with the scraping plate 33 on another adjacent intake component 3, so that the turbid liquid attached to the outside of the scraping plate 33 can be sucked into the corresponding next side groove 22 along with the diversion seat 31 under the action of air flow, preventing the accumulation of turbid liquid on the outside of the scraping plate 33. The lower part of the collection seat 32 is an arc-shaped structure protruding downward, so that the side groove 22 is also an arc-shaped structure protruding downward. The deeper into the side groove 22, the greater the air flow velocity. The air flow received by the turbid liquid and the like entering the side groove 22 continuously increases, which can accelerate the rapid passage of the turbid liquid and the like through the side groove 22, making it difficult for the turbid liquid to accumulate in the side groove 22.

[0028] During use, the arc-shaped scraping rod 2 is attached to the inner wall of the parturient's uterus and gently scraped to scrape the attachments and turbid liquid inside the uterus. Under the action of air flow, the attachments partially cover the arc-shaped scraping rod 2. At this time, it is not necessary to completely scrape off the attachments. Only when the scraping plate 33 rotates to the position of the attachments, the scraping plate 33 further scratches the attachments, so as to scrape the attachments off the inner wall of the uterus. The advantage of this effect is that the arc-shaped scraping rod 2 does not need to apply a large pressure to the uterus, nor does it need to quickly rub against the inner wall of the uterus to remove the attachments on the surface of the uterus, avoiding the problem of uterine injury caused by rapid friction.

[0029] During use, the arc-shaped scraping rod 2 separates the inner wall of the uterus and the scraping plate 33, so that there is a gap between the inner wall of the uterus and the scraping plate 33, allowing air flow to enter the gap and suck the turbid liquid and other substances in the gap into the side groove 22. This prevents the entrance of the side groove 22 from being covered by the inner wall of the uterus, solving the problem of the inner wall of the uterus being damaged due to the side groove 22 sucking the inner wall of the uterus.

[0030] Based on this assembly, when the support plate 34 passes through the arc scraper 2, the arc scraper 2 is supported, and when the arc scraper 2 is deformed, it is easy to restore the arc scraper 2, so that the scraper 33 can just pass through the arc scraper 2 without being blocked by the arc scraper 2 due to the deformation of the arc scraper 2. When the scraper 33 just passes through the arc scraper 2, it fits with the surface of the arc scraper 2 and scrapes off the attachments and turbid liquid on the surface of the arc scraper 2. When the support plate 34 supports the arc scraper 2, the pressure of the arc scraper 2 on the inner wall of the uterus is significantly increased, and the resistance of the arc scraper 2 is significantly increased. The doctor can judge the pressure of the arc scraper 2 on the inner wall of the uterus based on this situation, so as to reduce the pressure in time. When the arc-shaped scraper rod 2 exerts a greater pressure on the uterus, it will entangle larger attachments on the inner surface of the uterus. In the process of supporting the arc-shaped scraper rod 2, the support plate 34 will cut the attachments entangled on the surface of the arc-shaped scraper rod 2, making it convenient to cut large attachments into small parts, so that the scraper plate 33 can more easily scrape off the attachments on the surface of the uterus under the action of airflow, solving the problem of large-sized attachments being highly sticky and adhering to the surface of the uterus, making it inconvenient to remove.

[0031] The discharge assembly 5 includes a collecting pipe 51 movably arranged on the inner side of the mounting frame 1, and a spiral rod 52 movably arranged on the inner side of the collecting pipe 51. The flow guide seat 31 and the collecting seat 32 are fixedly arranged on the side of the collecting pipe 51, and the flow guide seat 31 and the collecting seat 32 are alternately arranged. The inside of the collecting pipe 51 is provided with a through-port 8 penetrating the groove wall of the side groove 22, and the spiral rod 52 transports the turbid liquid entering from the through-port 8 to the negative pressure assembly 6. The conveying function of the spiral rod 52 can discharge the internal turbid liquid and attachments from the device as soon as possible, and prevent the turbid liquid and attachments in multiple intake assemblies 3 from gathering and attaching to the inside of the collecting pipe 51 after entering the collecting pipe 51, so that the turbid liquid and attachments inside the collecting pipe 51 can be discharged in time. The number of through-ports 8 and side grooves 22 is the same and corresponds one to one.

[0032] Based on this component, the spiral rod 52 will produce slight vibrations during operation. This vibration will cause the pressure of the arc scraper 2 on the surface of the uterus to change slightly. The doctor can clearly sense the amplitude of this change when using it. When the doctor presses the arc scraper 2 on the surface of the inner wall of the uterus and the pressure is very high, the vibration amplitude generated by the operation of the spiral rod 52 will be significantly reduced, so that the doctor can also judge the pressure of the arc scraper 2 on the inner wall of the uterus according to the vibration of the device, and reduce the force in time when the pressure is too high. Therefore, the doctor can also better use this device to clean the uterus of pregnant women without causing damage to the uterus.

[0033] The arrangement of the screw rod 52 facilitates the cleaning of the interior of the device. After the device is used, the device is placed in a disinfectant. During the rotation of the screw rod 52, the disinfectant can be pumped into the interior of the device through the side groove 22 and discharged into the negative pressure assembly 6 through the through port 8, enabling the disinfectant to quickly enter and exit the interior of the device, resulting in better sterilization and cleaning effects for the device.

[0034] Among them, a plurality of abutting plates 34 are evenly spaced on the side surface of the scraping plate 33, and the leading corner of the plurality of abutting plates 34 passing by one side of the arc-shaped scraping rod 2 is an arc structure.

[0035] Based on this design, the arrangement of the plurality of abutting plates 34 provides a more uniform supporting effect on the arc-shaped scraping rod 2, facilitating the restoration of the arc-shaped scraping rod 2 to its original state. The arc-shaped structure of the corners of the abutting plates 34 makes it easier for the abutting plates 34 to support the deformed arc-shaped scraping rod 2.

[0036] Among them, the diversion seat 31 is closely attached to the surface of the scraping plate 33 in the intake assembly 3 closest to it. First current-limiting plates 9 are fixedly arranged on both sides of the diversion seat 31. Second current-limiting plates 10 adapted to the first current-limiting plates 9 are arranged on both sides of the collection seat 32. Sealing sheets 11 are fixedly arranged on both sides of the mounting frame 1. The sealing sheets 11 are in contact with the adjacent first current-limiting plates 9 and second current-limiting plates 10. The aggregate pipe 51 is movably and sealingly connected to the mounting frame 1.

[0037] Based on this design, it is used to improve the sealing performance of the connections of the device, prevent problems such as liquid leakage, facilitate the cleaning of the device, and avoid the problem of inconvenient cleaning of dead corners.

[0038] Among them, the holding assembly 4 includes a grip rod 41, a U-shaped frame 42 fixedly installed at one end of the grip rod 41, and an anti-slip sleeve 43 fixedly installed on the side surface of the other end of the grip rod 41. Mounting seats 12 are respectively fixedly arranged at both ends of the U-shaped frame 42. The mounting frame 1 is fixedly arranged inside the two mounting seats 12. The screw rod 52 is respectively movably connected to the two mounting seats 12.

[0039] Based on this design, it is convenient to install and use the screw rod 52.

[0040] The discharge assembly 5 further includes a shaft ring 53, a planetary gear set 54, a connecting plate 55, a positioning seat 56 and a driving motor 57 arranged on one side of the inner side of the collecting pipe 51. The shaft ring 53 is fixedly connected to the collecting pipe 51, the connecting plate 55 is located between the planetary gear set 54 and the shaft ring 53, the connecting plate 55 is fixedly connected to the gear ring of the planetary gear set 54, the connecting plate 55 is fixedly connected to the shaft ring 53 through the screw 13, the positioning seat 56 is fixedly connected to the planet carrier of the planetary gear set 54, and the rod shaft of the screw rod 52 is respectively connected to the planet carrier of the planetary gear set 54. The shaft ring 53, the sun gear of the planetary gear set 54 and the positioning seat 56, the rod shaft of the screw rod 52 and the shaft ring 53 are movably sealed and connected, the rod shaft of the screw rod 52 and the sun gear of the planetary gear set 54 are fixedly connected, the positioning seat 56 and the mounting seat 12 adjacent thereto are fixedly connected, an inner groove 14 is opened on the inner side of one end of the U-shaped frame 42, a transmission component 15 is arranged inside the inner groove 14, a driving motor 57 is fixedly arranged on the inner side of the U-shaped frame 42, and the driving motor 57 drives the screw rod 52 to rotate through the transmission component 15.

[0041] Based on this design, the transmission assembly 15 adopts the commonly used belt drive mechanism. The driving motor 57 drives the screw rod 52 to rotate through the transmission assembly 15. The screw rod 52 drives the shaft ring 53 to rotate through the planetary gear set 54 and the connecting plate 55. The shaft ring 53 drives the collection pipe 51 to reverse, so that the screw rod 52 rotates at a higher speed relative to the collection pipe 51, which is convenient for the screw rod 52 to scrape off the attachments on the surface of the collection pipe 51 and prevent the attachments from being deposited inside the collection pipe 51 and causing stubborn residues. The setting of the planetary gear set 54 is used to decelerate the collection pipe 51, so that the collection pipe 51 rotates at a low speed during the rapid rotation of the screw rod 52, so as to prevent the ingestion assembly 3 from rotating too fast.

[0042] Among them, an inner hole 16 is opened inside one side of the U-shaped frame 42, and a discharge port 17 is opened inside one of the mounting seats 12. The turbid liquid transported by the screw rod 52 enters the inner hole 16 through the discharge port 17. A drainage hole 18 penetrating the grip rod 41 is opened in the middle of the U-shaped frame 42. A connecting pipe 19 connecting the inner hole 16 and the drainage hole 18 is fixedly arranged on the inner side of the U-shaped frame 42. The feed end of the negative pressure assembly 6 is connected to the end of the grip rod 41 and is connected to the drainage hole 18.

[0043] The negative pressure component 6 generates negative pressure inside the collecting pipe 51 through the drainage hole 18, the connecting pipe 19 and the discharge port 17. The spiral rod 52 injects the turbid liquid and attachments in the collecting pipe 51 into the connecting pipe 19 through the discharge port 17, and then is extracted by the negative pressure component 6 through the drainage hole 18.

[0044] Among them, the negative pressure assembly 6 includes a first flexible tube 61 fixedly connected to the grip rod 41, a gas-liquid separator 62 fixedly connected to the discharge end of the first flexible tube 61, a second flexible tube 63 fixedly installed at the gas outlet end of the gas-liquid separator 62, and a negative pressure pump 64 fixedly connected to the gas outlet end of the second flexible tube 63.

[0045] Based on this design, the gas-liquid separator 62 is used to separate the turbid liquid attachments, and the negative pressure pump 64 is used to generate a negative pressure environment inside the device, playing a role in sucking the turbid liquid and attachments.

[0046] Among them, an intake pipe 20 is fixedly installed on one side of the U-shaped frame 42, and the intake end of the intake pipe 20 is connected to an intake assembly 7 through a third flexible tube 21.

[0047] The intake assembly 7 is used to directly introduce air into the uterus through the intake pipe 20, avoiding the generation of an inward airflow towards the uterus at the uterine entrance by the outside air, and preventing the problem that the airflow leads the turbid liquid at the uterine entrance into the uterus.

[0048] Among them, the intake assembly 7 includes a gas treatment tank 71, an air filter 72 fixedly arranged above the gas treatment tank 71, and an air heater 73 fixedly arranged at the bottom of the gas treatment tank 71. The air filter 72 filters the air entering the inside of the gas treatment tank 71, and the air heater 73 detects and heats the temperature of the airflow entering the inside of the gas treatment tank 71.

[0050] An obstetric delivery cleaning method includes the following steps: S1. First, hold the holding assembly 4 by hand and send the front part of the holding assembly 4 into the uterus of the parturient. Press the arc-shaped scraping rod 2 against the inner wall of the parturient's uterus and scrape. The turbid liquid scraped out adheres to the surface of the arc-shaped scraping rod 2. When the pressure of the arc-shaped scraping rod 2 on the inner wall of the parturient's uterus is too large, it deforms itself; S2. Then, use the negative pressure assembly 6 to generate negative pressure in each side groove 22. When the intake assembly 3 passes by the arc-shaped scraping rod 2 with turbid liquid attached, it sucks away the turbid liquid. When the intake assembly 3 passes by the arc-shaped scraping rod 2 touching the inner wall of the uterus, the backing plate 34 supports the arc-shaped scraping rod 2. When the scraping plate 33 touches the arc-shaped scraping rod 2, it does not contact the inner wall of the uterus. During the rotation of the scraping plate 33 passing through the arc-shaped scraping rod 2, it cooperates with the suction of the airflow to take away the stubborn attachments adhering to the inner wall of the uterus. When the backing plate 34 passes through the arc-shaped scraping rod 2, it divides the large-sized attachments adhering to the surface of the arc-shaped scraping rod 2 into small-sized ones, and the attachments are sucked into the inside of the side groove 22; S3. The turbid liquid and the attachments enter the interior of the aggregate pipe 51 through the through port 8, and the screw rod 52 conveys the turbid liquid and the attachments towards the negative pressure assembly 6.
