Description

Technical Field

[0001] The present invention relates to the field of medical devices, and particularly to a treatment device for pediatric intussusception with adjustable flow rate and stable pressure output. Background Art

[0002] Pediatric intussusception is one of the common acute abdominal diseases in pediatrics. The main treatment method is non-surgical reduction, and the enema reduction method is widely used in clinical practice due to its small trauma and quick recovery. Traditional enema equipment injects liquid into the intestine by manual extrusion and uses ultrasonic imaging to assist in observing the reduction effect. In the prior art, such equipment usually consists of a simple injection device (such as a syringe) and a pipeline, and relies on medical staff to manually control the liquid flow rate and pressure. Although this method can achieve reduction to a certain extent, its core problem lies in the high dependence on the operator's experience and the lack of precise pressure and flow rate control mechanisms.

[0003] The existing enema equipment in the prior art has the following problems:

[0004] Large pressure fluctuation: When manually squeezing and injecting, the liquid output pressure is significantly affected by the operation force and frequency, resulting in unstable pressure. This fluctuation may cause intestinal discomfort to the patient and even cause mucosal damage, affecting the success rate of reduction.

[0005] Difficult flow rate control: The existing equipment lacks a precise flow rate adjustment device, and medical staff need to adjust the injection speed based on experience, making it difficult to achieve personalized treatment matching the individual conditions of the child.

[0006] Complicated operation and insufficient safety: The equipment has a simple structure but a single function, lacking an automatic pressure relief and emergency protection mechanism. When the pressure exceeds the safety threshold, it relies on the operator's quick reaction, with the risk of delay or misoperation. In addition, most of the existing equipment is reused, with the potential risk of cross-infection.

[0007] The above problems lead to the drawbacks of low treatment efficiency, poor safety, and limited application scope in the clinical application of the prior art. Especially for primary medical institutions, the operation threshold is relatively high and it is difficult to popularize.

[0008] Therefore, there is an urgent need in this field for an enema reduction device that can integrate stable pressure control, precise flow rate adjustment, multiple safety protections, and a disposable use design to improve the reliability, safety, and universality of pediatric intussusception treatment.

[0031] The purpose of the present invention is to provide a pediatric intussusception treatment device with adjustable flow rate and stable pressure output to solve the problems existing in the prior art.

[0032] To make the above objects, features, and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1:

[0034] This example provides a pediatric intussusception treatment device with adjustable flow rate and stable pressure output, as Figure 1 shown, including:

[0035] An enema solution storage component 1, in which enema solution is stored. In this example, the enema solution uses physiological saline;

[0036] Of course, in other embodiments, sodium phosphate, glycerol, etc. can also be used as the enema solution. The enema solution storage component 1 in this example does not limit the type of enema solution;

[0037] An adjustable-speed and stable-flow injection component 2, which is connected to the enema solution storage component 1 through a first one-way valve 3 and is used for manual control to achieve rapid introduction and uniform discharge of the enema solution;

[0038] A buffer constant-pressure chamber 4, which is connected to the adjustable-speed and stable-flow injection component 2 through a second one-way valve 5 and is used for buffering and constant-pressure treatment of the enema solution to avoid discomfort during enema;

[0039] A pressure relief component 6, which is arranged on the buffer constant-pressure chamber 4 and provides various pressure relief methods to ensure pressure balance and safety during the enema process.

[0040] As an implementation method, the adjustable-speed and stable-flow injection component 2, the buffer constant-pressure chamber 4, and the pressure relief component 6 are all integrated in a housing 7. The housing 7 can adopt a transparent structure to facilitate observing the flow of the enema solution, making the device more integrated. Of course, the housing 7 can be opened to facilitate replacing the adjustable-speed and stable-flow injection component 2 and the buffer constant-pressure chamber 4 with different capacities according to the needs of different patients. A display screen can be set on the surface of the housing to facilitate medical staff to understand the parameters such as pressure and flow rate displayed on the display screen in real time; an inlet quick connector 71 and an outlet quick connector 72 are provided on the side of the housing 7. The inlet quick connector 71 is connected to the first one-way valve 3, so that the enema solution in the enema solution storage component 1 can flow into the adjustable-speed and stable-flow injection component 2 unidirectionally; the outlet quick connector 72 is connected to the buffer constant-pressure chamber 4, so that the buffer constant-pressure chamber 4 can be quickly connected to the enema pipeline to discharge the enema solution in the buffer constant-pressure chamber 4.

[0041] As an implementation method, both the inlet quick connector 71 and the outlet quick connector 72 adopt standard Luer connectors to ensure direct connection with existing pipeline consumables.

[0042] As an implementation manner, the enema solution storage assembly 1 includes an enema solution storage tank. The top of the enema solution storage tank is provided with a filling port for facilitating the injection of the enema solution. The bottom of the enema solution storage tank is provided with a liquid outlet pipe, and the liquid outlet pipe is detachably connected to the inlet quick connector, thereby realizing the derivation of the enema solution.

[0043] As an implementation manner, the adjustable-speed and steady-flow injection assembly 2 includes a large cylinder body 21. A small cylinder body 22 is concentrically arranged inside the large cylinder body 21. Both can be made of transparent medical plastic for facilitating the observation of the remaining liquid amount. The two are connected by a liquid passing plate 23. The liquid passing plate 23 not only plays a connecting role but also allows the enema solution to flow through. The end of the small cylinder body 22 is provided with a liquid passing hole 24, which can realize the communication between the small cylinder body 22 and the large cylinder body 21, thereby ensuring that the liquid injected by the two flows out evenly. The end of the large cylinder body 21 is provided with a flow channel 25, and the flow channel 25 is connected to the second one-way valve 5. An annular piston 26 is arranged in the large cylinder body 21 in a matching manner, and a small piston 27 is arranged in the small cylinder body 22 in a matching manner. Both the annular piston 26 and the small piston 27 are connected to a push plate 29 through a push rod 28. By pushing the push plate 29, the push rod 28 can drive the annular piston 26 and the small piston 27 to move, squeeze the enema solution, and then push the enema solution out evenly.

[0044] As an implementation manner, an adjusting ball valve 8 and a flow rate sensor 9 are arranged on the flow channel 25. By rotating the adjusting ball valve 8, the opening size of the flow channel 25 is adjusted to further adjust the flow rate, and the flow rate is monitored in real time through the flow rate sensor 9 and displayed on the display screen at the same time, which is convenient for medical staff to understand the flow rate information in real time.

[0045] As an implementation manner, a large cavity and a small cavity are arranged in the buffer constant pressure chamber 4. The large cavity and the small cavity are arranged alternately, and the large cavity and the small cavity are communicated through a distribution channel. Both the large cavity and the small cavity are provided with elastic side walls. Through the multi-cavity design and the elastic side walls, the distribution of the enema liquid can be made uniform, the stability of the pressure output can be ensured, and the pressure fluctuation can be reduced.

[0046] As an implementation manner, the elastic side wall adopts a flexible bladder. Of course, in other embodiments, an elastic membrane can also be used, and medical silicone or polyurethane materials are used to improve flexibility and durability. As long as it can play a role in reducing pressure fluctuation, it is within the protection scope of the present invention.

[0047] As an implementation manner, a pressure sensor is arranged in the buffer constant pressure chamber 4 to monitor the liquid pressure in real time and feedback it to the medical staff through the display screen, further improving the accuracy.

[0048] As an implementation manner, the pressure relief component 6 includes an automatic pressure relief valve, a manual pressure relief valve, and an emergency pressure relief valve. Among them, the automatic pressure relief valve can automatically release the liquid exceeding the set safety pressure to prevent excessive pressure; the manual pressure relief valve enables medical staff to adjust the pressure relief magnitude through a knob to precisely control the pressure during the enema process; the emergency pressure relief valve enables medical staff to quickly release the liquid pressure in the device in case of an emergency to ensure treatment safety. All of them belong to the prior art, and the specific principles and structures will not be elaborated in this application.

[0049] The enema liquid is injected through the adjustable speed and stable flow injection component 2 and enters the buffer constant pressure chamber 4 through the second one-way valve 5. In the buffer constant pressure chamber 4, the liquid outputs a stable pressure through the buffering effect of the multi-chamber and the elastic side wall. If the pressure exceeds the safety range, the automatic pressure relief valve or the manual pressure relief valve is activated to ensure pressure safety. In case of an emergency, the emergency pressure relief valve button can directly release the pressure.

[0050] The present invention elaborates on the principle and implementation manner of the present invention by applying specific examples. The description of the above embodiments is only used to help understand the method and its core idea of the present invention; at the same time, for those of ordinary skill in the art, according to the idea of the present invention, there will be changes in the specific implementation manner and application scope. In summary, the content of this specification should not be construed as a limitation to the present invention.
