Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of medical care devices, specifically a constant temperature and constant pressure cleaning device for urology. Background Art
[0002] The cleaning and nursing device for urology is a commonly used medical device auxiliary device. Generally, when urology patients are undergoing recovery treatment, they need to be cleaned and disinfected regularly.
[0003] In order to ensure the comfort of patients during the cleaning process, the existing cleaning and nursing devices for urology usually need to ensure the constancy of the pressure during infusion. In the existing devices, the nursing solution usually directly adjusts the pressure during transportation to complete the spraying and washing. Although this method can adjust the pressure in a short time, it is difficult to maintain a long-term constant pressure. The pressure fluctuation will cause the spraying effect of the nursing solution to be unstable, and there may be problems such as the flow rate of the nursing solution being too fast or too slow. This not only affects the cleaning effect but also may cause additional irritation and discomfort to the patients. Especially when there is a pressure change in the sensitive area of the urinary tract during the cleaning process, it is more likely to cause discomfort or pain to the patients.
[0004] In addition, too high a temperature of the nursing solution may cause a burning sensation in the patient, while too low a temperature is likely to cause cold discomfort or induce a bladder irritation reflex. This temperature instability not only affects the patient experience but also may have an adverse impact on patients during the postoperative or disease recovery period, prolonging the recovery time. Summary of the Invention

[0030] 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 shall fall within the protection scope of the present invention.
[0031] In the description of the present invention, it should be understood that the orientation or positional relationships indicated by the terms "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. are based on the orientation or positional relationships shown in the drawings. These are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present invention.
[0032] In addition, terms such as "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.
[0033] It should be noted that, without conflict, the features in the embodiments of the present invention can be combined with each other.
[0034] During the use of existing urological cleaning and nursing devices, the inventor of the present invention found the following main problems.
[0035] In existing devices, the nursing solution is usually directly sprayed and washed by adjusting the pressure during transportation. Although this method can adjust the pressure in a short time, it is difficult to maintain a long-term constant pressure. The pressure fluctuation will cause the spraying effect of the nursing solution to be unstable, and problems such as the flow rate of the nursing solution being sometimes fast and sometimes slow may occur. This not only affects the cleaning effect but also may cause additional irritation and discomfort to the patient. Especially when pressure changes occur in sensitive areas of the urinary tract during the cleaning process, it is more likely to cause discomfort or pain to the patient.
[0036] The temperature of the nursing solution is an important factor affecting the patient's comfort, but existing cleaning devices 30 have deficiencies in temperature regulation. The temperature of the nursing solution is easily affected by the external environment or unstable operation of the device, resulting in fluctuations near the set value or even large deviations. Too high a temperature of the nursing solution may cause a burning sensation in the patient, while too low a temperature is likely to cause cold discomfort or induce a bladder irritation reflex. This temperature instability not only affects the patient's experience but also may have an adverse impact on patients during the postoperative or disease recovery period, prolonging the recovery time.
[0037] Existing cleaning devices 30 are usually designed according to a unified standard and do not fully consider the individual needs of different patients, such as sensitivity differences, physical differences, etc. This "one-size-fits-all" design makes the cleaning process too stimulating or too gentle for some patient groups, reducing the applicable range and nursing efficiency of the device.
[0038] In summary, existing urological cleaning and nursing devices have deficiencies in pressure stability, temperature regulation, and individual adaptability, and further optimization of the design is needed to improve the patient's comfort and nursing effect.
[0039] To solve the above problems, in combination with Figures 1 to 3 As shown, in the embodiments of the present invention, a constant-temperature and constant-pressure cleaning device for urology is proposed. This device effectively combines constant pressure regulation and precise temperature control, solves the technical shortcoming in the existing urology cleaning and nursing devices that the pressure and temperature cannot be stabilized simultaneously, and significantly improves the comfort, safety and efficiency of the cleaning process.
[0040] Specifically, the cleaning device 30 includes a liquid storage tank 10 for storing the nursing solution. The liquid storage tank 10 is used to store the nursing solution and is connected to a pressure regulating device 20 through a catheter, providing an initial source for the delivery of the nursing solution. The liquid storage tank 10 is equipped with a temperature control device, that is, the temperature regulating device 40 described below, for initially adjusting the temperature of the nursing solution to meet the cleaning requirements. The catheter ensures the continuity and stability of the flow of the nursing solution.
[0041] The pressure regulating device 20 is divided into two levels: the first pressure regulating unit 201 and the second pressure regulating unit 203, which are responsible for finely regulating the pressure of the nursing solution delivery step by step. Among them, the first pressure regulating unit 201 adopts a symmetrical double-channel structure. After the nursing solution enters, it is split into two channels for pressure regulation respectively. This symmetrical structure design has the advantages of pressure dispersion, uniform flow distribution and stable structure. More specifically, the symmetrical double-channel structure reduces the pressure fluctuation of a single channel through splitting, reduces the fluctuation range of the flow rate of the nursing solution, makes the flow distribution of the nursing solution more uniform, and reduces the burden on the subsequent pressure regulating unit. In addition, the symmetrical structure reduces the risk of mechanical fatigue and damage that may be caused by unbalanced design.
[0042] The second pressure regulating unit 203 adopts a single-channel structure and is responsible for more precise pressure regulation of the nursing solution. This single-channel design can effectively avoid the pressure interference that may be generated by multiple channels and ensure the stability and accuracy of the output pressure.
[0043] Referring to Figure 2 , the pressure regulating device 20 includes two grading devices: the first grading device 202 and the second grading device 204, which are respectively used for coarse and fine pressure regulation.
[0044] Specifically, the first grading device 202 is located between the first pressure regulating unit 201 and the second pressure regulating unit 203 and adopts a multi-stage pressure regulation range design. It can perform a large-range pressure adjustment on the nursing solution according to the set pressure range. It can be understood that by setting multiple pressure intervals, it is ensured that the pressure of the nursing solution can be quickly adjusted to be close to the target range. In addition, in some embodiments of the present invention, the difference between any two pressure ranges set in the first grading device 202 is relatively large, so that the preliminary pressure regulation can be carried out more efficiently, providing a basis for subsequent fine regulation.
[0045] The second grading device 204 is located between the second pressure regulating unit 203 and the delivery pipe 301. Its main function is to precisely adjust the pressure of the nursing solution within a small range. By setting a small pressure range difference, it ensures that the pressure of the nursing solution finally delivered into the patient's body is more stable. It can be understood that by adjusting within a small range, the pressure fluctuation is controlled within the lowest range, improving the nursing effect.
[0046] After the pressure of the nursing solution is regulated by the second grading device 204, it directly flows into the nozzle 302 through the delivery pipe 301 for spraying and washing work. It should be noted here that the inner wall of the pipeline is usually designed with anti-blocking and corrosion-resistant materials to ensure the reliability of long-term use.
[0047] In some embodiments of the present invention, the first grading device 202 for large-range pressure regulation can be, but is not limited to, a mechanical grading regulating valve and a pressure regulator, etc. Among them, the mechanical grading regulating valve adjusts the fluid pressure by changing the cross-sectional area of the flow channel or increasing the resistance through a mechanical structure; the pressure regulator can adopt a spring-loaded pressure regulator, a valve loaded with a spring, and adjusts the pressure in grades according to the flow rate of the nursing solution and the compression degree of the spring.
[0048] Assume that the initial pressure of the nursing solution is 1.5 MPa, and the target pressure is 0.5 MPa - 0.8 MPa. The first grading device 202 roughly adjusts the pressure from 1.5 MPa to about 0.8 MPa, and then the second grading device 204 performs fine adjustment.
[0049] The second grading device 204 is located between the second pressure regulating unit 203 and the delivery pipe 301, and is used for fine adjustment of the nursing solution pressure within a small range. Common implementation methods include a fine adjustment needle valve, a diaphragm pressure regulator, and an electronic pressure regulating system, etc. On the basis of the rough adjustment by the first grading device 202, the second grading device 204 further controls the pressure at an accurate value within the target range, that is, the goal is to precisely fine-tune the pressure of the nursing solution to ensure that the final output pressure meets the needs of the patient.
[0050] Assume that after the rough adjustment by the first grading device 202, the pressure of the nursing solution is 0.8 MPa, and the target pressure is 0.7 MPa ± 0.05 MPa. If a fine adjustment needle valve is used, the second grading device 204 gradually reduces the channel opening degree, and the pressure gradually drops from 0.8 MPa to 0.75 MPa, and then is adjusted to 0.7 MPa.
[0051] In summary, the symmetric dual-flow channel structure of the first pressure regulating unit 201 can effectively reduce the fluctuations during the fluid pressure regulation process, and reduce the burden on a single channel through flow splitting. This design can not only ensure the flow uniformity of the nursing solution, but also improve the stability and service life of the pressure regulating device 20. The second pressure regulating unit 203 adopts a single-flow channel structure, eliminating the possible pressure interference problems between multiple flow channels, and the output pressure is more uniform, which can ensure that the nursing solution is delivered to the patient's body under a constant pressure, reducing discomfort and potential injury risks.
[0052] In addition, through the collaborative work of the first grading device 202 and the second grading device 204, the pressure regulation of the nursing solution is divided into two steps: large-range regulation and small-range fine-tuning. The first grading device 202 conducts a large-range rough adjustment of the pressure to quickly reduce or increase the pressure of the nursing solution; the second grading device 204 is responsible for fine adjustment, and finally outputs a constant pressure that meets the patient's needs. The two-stage pressure regulating design significantly improves the stability of the nursing solution delivery pressure and avoids the pressure fluctuation problems that may be caused by direct pressure regulation.
[0053] It can be understood that the division of labor between the grading devices is clear, reducing the workload of a single pressure regulating unit, improving the reliability and maintainability of the system, and the symmetric structure and single-flow channel design also further reduce the probability of equipment failure due to mechanical fatigue. The large-range pressure regulation combined with small-range fine-tuning enables the device to adapt to the personalized needs of different patients, including sensitive patients after urological surgery and regular cleaning patients during the recovery period. Through the above design, the cleaning device 30 can achieve significant improvements in terms of pressure regulation and delivery stability, providing a more comfortable, safe and efficient solution for urological care.
[0054] Reference Figure 1 and Figure 3 This cleaning device 30 also includes a cleaning device 30, which includes the following key components: a delivery pipe 301 connects the pressure regulating device 20 and the nozzle 302, and is used to deliver the nursing solution after pressure regulation and temperature adjustment; the nozzle 302 is located at the end of the delivery pipe 301 and is designed as a multi-hole or single-hole nozzle 302, and is used to evenly spray the nursing solution onto the target area. The material of the delivery pipe 301 is usually selected as flexible and corrosion-resistant medical silicone or polymer to ensure safety and long life. The nozzle 302 usually has an anti-clogging design and supports different modes of spraying (such as spraying, flushing, etc.) to adapt to different cleaning requirements.
[0055] It can be understood that the nursing solution is transferred from the liquid storage tank 10 through the first pressure regulating unit 201 and the second pressure regulating unit 203 of the pressure regulating device 20. After the pressure is graded and regulated, it is transmitted to the nozzle 302 through the delivery pipe 301 and finally sprayed out to complete the cleaning process of the target area.
[0056] The temperature control device 40 includes the following key components: a heating unit 401 located inside the liquid storage tank 10 for heating the nursing solution, and a detection unit 402 located inside the delivery pipe 301 and near the connection between the delivery pipe 301 and the pressure regulating device 20 for real-time detection of the temperature of the nursing solution.
[0057] Among them, the heating unit 401 can be designed with an electric heating rod, a heating plate or a heating tube, and can quickly heat the nursing solution to the target temperature range. Its power size is designed according to the capacity of the nursing solution. For example, a heating element with a power of 100W - 300W can be equipped for 1L of nursing solution. In addition, the heating unit 401 is often equipped with a stirrer or a circulation device to ensure that the nursing solution in the liquid storage tank 10 is evenly heated and avoid local overheating.
[0058] The detection unit 402 is close to the connection between the outlet of the pressure regulating device 20 and the delivery pipe 301, and can accurately reflect the temperature state of the nursing solution after pressure regulation, ensuring that the nursing solution contacted by the patient always meets the set temperature range. The detection unit 402 can adopt a thermistor or a thermocouple sensor, which has the characteristics of high sensitivity and fast response.
[0059] It can be understood that the heating unit 401 adjusts the heating power in real time according to the temperature value feedback by the detection unit 402 to ensure that the temperature of the nursing solution is close to the set threshold. For example, when the set temperature is 37°C, if the detected temperature of the nursing solution is 35°C, the heating unit 401 will automatically increase the power for heating; if the detected temperature of the nursing solution is 38°C, the heating unit 401 will stop heating or reduce the power; after the temperature stabilizes, the heating unit 401 enters the heat preservation state to reduce energy consumption.
[0060] In summary, the temperature control device 40 combines the dynamic regulation of the detection unit 402 and the heating unit 401, and can adjust the temperature of the nursing solution in real time while ensuring that the output temperature is stable within the set range, avoiding discomfort to the patient caused by being too cold or too hot. The detection unit 402 is located near the outlet inside the delivery pipe 301 and can reflect the temperature of the actually delivered liquid, rather than the local temperature of the liquid storage tank 10, improving the accuracy of temperature control. During the cleaning process, the pressure regulating device 20 ensures that the pressure of the nursing solution is constant when it is ejected, avoiding irritation to the patient caused by pressure fluctuations. The constant pressure and stable temperature output of the nursing solution significantly improve the comfort during the cleaning process, and are especially suitable for the sensitive nursing needs of urological patients. This design realizes the dual stability of pressure and temperature of the cleaning device 30, ensuring the safety, efficiency and comfort of urological cleaning and nursing, and providing a better medical experience for patients.

The patent protection scope of the present invention is subject to the claims. Any equivalent structural changes made by using the description and drawings of the present invention should be included in the protection scope of the present invention by the same token.
