Abstract
Description
Technical Field
[0001] This utility model relates to the field of bladder irrigation technology, and more specifically, to a heated irrigation device for bladder irrigation. Background Technology
[0002] The content in this section only provides background information related to this utility model and may not constitute prior art.
[0003] For patients who have undergone bladder surgery, in order to prevent postoperative infection, it is usually necessary to regularly and slowly flush the patient's bladder with a flushing solution.
[0004] Currently, common flushing methods include closed-system flushing. In closed-system flushing, the flushing solution is temporarily stored in a reservoir such as an IV bottle, and the reservoir is equipped with a drainage tube. During flushing, the reservoir containing the flushing solution is fixed to a carrier such as an IV stand, and the drainage tube leading from the reservoir is connected to a urinary catheter inserted in the patient's body. This allows the flushing solution in the reservoir to flow sequentially through the drainage tube and the urinary catheter to flush the patient's bladder.
[0005] Furthermore, when performing bladder irrigation, the temperature of the irrigation solution should be controlled within a target temperature range such as 28-32℃. If an irrigation solution with a temperature that is too low is used for bladder irrigation, it will not only cause discomfort to the patient, but may also cause adverse symptoms such as spasms.
[0006] In related technologies, a common method for controlling the temperature of the flushing solution is to directly heat the solution within the reservoir. However, this method has drawbacks. During bladder irrigation, the flushing solution must flow through a relatively long catheter before reaching the catheter, which is exposed to the external environment. Therefore, if the ambient temperature is too low, the temperature of the flushing solution flowing through the catheter will drop rapidly, potentially resulting in the temperature of the flushing solution reaching the catheter being lower than the target temperature range. Summary of the Invention
[0007] In view of this, the purpose of this utility model is to provide a heated flushing device for bladder irrigation, so as to ensure that the temperature of the flushing solution reaching the catheter is within the target temperature range even when the external ambient temperature is too low.

Detailed Implementation
[0038] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below in conjunction with specific embodiments. The same reference numerals in the accompanying drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0039] Compared to the embodiments shown in the accompanying drawings, feasible embodiments within the scope of protection of this utility model may have fewer components, have other components not shown in the drawings, different components, components arranged differently, or components with different connections, etc. Furthermore, two or more components shown in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.
[0040] An embodiment of this utility model discloses a heated flushing device for bladder irrigation (hereinafter referred to as "heated flushing device" for ease of explanation).
[0041] like Figure 1 As shown, it illustrates the external shape of the exemplary heated rinsing apparatus disclosed in this embodiment. Figure 1 In the heated flushing shown, the heated flushing device may include a liquid storage container 10, a guide tube 20, a heating unit 30, and a urinary catheter 40.
[0042] In this embodiment, the reservoir 10 defines a reservoir cavity suitable for storing the flushing solution. For example, the reservoir 10 can be an infusion set with a hanging ring, so that the reservoir 10 can be temporarily fixed to a carrier such as an infusion stand in a suspended manner during bladder flushing.
[0043] The drainage tube 20 is used to guide the flushing solution in the reservoir to the urinary catheter 40, so that the flushing solution can be delivered to the patient's bladder through the urinary catheter 40 to flush the patient's bladder.
[0044] Specifically, the drainage tube 20 may have an inlet and an outlet. The inlet of the drainage tube 20 is connected to the reservoir cavity of the reservoir 10, and the outlet of the drainage tube 20 is connected to the catheter 40. A switch, such as a flow regulator 50, may be installed on the drainage tube 20. Thus, during bladder irrigation, simply opening the switch on the drainage tube 20 allows the irrigation solution in the reservoir cavity of the reservoir 10 to enter the drainage tube 20 through the inlet and eventually flow out from the outlet of the drainage tube 20 into the catheter 40.
[0045] In this embodiment, the heating unit 30 is used to heat the rinsing solution flowing through the guide pipe 20, especially the rinsing solution flowing through the guide pipe 20 and close to the output end of the guide pipe 20.
[0046] It is understood that in this embodiment, the flushing solution flowing through the guide tube 20 and near the output end of the guide tube 20 is heated by the heating unit 30. Compared with the known method of heating the flushing solution in the storage chamber of the storage container 10 in the prior art, the flushing solution heated to the target temperature (e.g., 28-32°C) by the heating unit 30 will directly enter the catheter 40 through the output end of the guide tube 20. Therefore, even when the external ambient temperature is too low, the heated flushing device can flush the patient's bladder and the temperature of the flushing solution reaching the catheter 40 can be kept within the target temperature range as much as possible.
[0047] Considering that the flushing solution in the drainage tube 20 is always in a slow flow state during bladder irrigation, in order to heat the flushing solution flowing through the drainage tube 20 and near the output end of the drainage tube 20 to the target temperature in the shortest possible time, this embodiment further defines the structure of the heating unit 30.
[0048] Combination Figure 2 and Figure 3 As shown, the heating unit 30 may include a housing 31 and a heating element 32. The housing 31 defines a heating cavity 33 suitable for storing a heat-conducting medium. The heat-conducting medium may be a common heat-conducting medium such as heat-conducting oil or water.
[0049] The heating element 32 is configured to heat the heat-conducting medium within the heating chamber 33. The portion of the guide tube 20 near its output end is located within the heating chamber 33 and immersed in the heat-conducting medium, while the output end of the guide tube 20 is located outside the heating chamber 33. To facilitate the installation of the heating element 32, the heating unit 30 may also include a base 34 disposed at the bottom of the housing 31. The base 34 and the housing 31 can be detachably connected by means such as a threaded connection. The heating element 32 can be mounted on the base 34, and the housing 31, connected to the base 34, is supported on the heating element 32, so that the heating element 32 faces the heating chamber 33 inside the housing 31, thereby facilitating reliable heating of the heat-conducting medium within the heating chamber 33 by the heating element 32. The heating element 32 may be, but is not limited to, a heating plate.
[0050] Thus, during actual bladder irrigation, the heating element 32 first heats the heat-conducting medium in the heating chamber 33 to a suitable temperature. Then, the irrigation solution in the reservoir 10 flows through the inlet of the guide tube 20 and finally exits from the outlet of the guide tube 20 into the catheter 40. It is understood that since the portion of the guide tube 20 near its outlet is completely immersed in the heat-conducting medium of the heating chamber 33, when the irrigation solution flows through the portion of the guide tube 20 immersed in the heat-conducting medium, the pre-heated heat-conducting medium can quickly exchange heat with the irrigation solution in the guide tube 20, allowing the temperature of the irrigation solution flowing through the guide tube 20 to rise to the target temperature in a short time.
[0051] Further, such as Figure 2 or Figure 3 As shown, the flow guide pipe 20 may include a first pipe section 21, a second pipe section 22, and a third pipe section 23. One end of the first pipe section 21 can serve as the input end of the flow guide pipe 20 and communicate with the liquid storage chamber of the liquid storage container 10. The other end of the first pipe section 21 is connected to one end of the second pipe section 22. The aforementioned flow regulator 50 may be mounted on the first pipe section 21.
[0052] The other end of the second tube segment 22 is connected to one end of the third tube segment 23, and the other end of the third tube segment 23 can serve as the output end of the guide tube 20 and be connected to the urinary catheter 40. Furthermore, the second tube segment 22 is located inside the heating chamber 33 and is immersed in the heat-conducting medium, and the second tube segment 22 located inside the heating chamber 33 can be spiral-shaped.
[0053] Understandably, by arranging the second pipe section 22 within the heating chamber 33 in a spiral shape, it is beneficial to extend the flow time of the rinsing solution within the second pipe section 22, thereby ensuring that the temperature of the rinsing solution flowing out from the output end of the guide pipe 20 is within the target temperature range as much as possible. Specifically, the end of the second pipe section 22 that connects to the first pipe section 21 is higher than the end that connects to the third pipe section 23, so that the rinsing solution can flow smoothly through the second pipe section 22 and into the third pipe section 23 under its own gravity without the need for an additional suction device. Furthermore, the second pipe section 22 can be a metal pipe made of a heat-conducting material, which facilitates heating the rinsing solution flowing through the second pipe section 22 to the target temperature in a shorter time.
[0054] Furthermore, combining Figure 2 and Figure 3 As shown, the heating unit 30 may further include a temperature detection component 35 and a control component 36. The temperature detection component 35 is configured to detect the temperature of the rinsing solution after it has flowed through the guide pipe 20 and been heated, and to issue a temperature detection signal. In this embodiment, the rinsing solution flowing through the guide pipe 20 and being heated specifically refers to the rinsing solution flowing through the second pipe section 22. Therefore, the temperature detection component 35 can specifically be used to detect the temperature of the rinsing solution flowing through the second pipe section 22 and to issue a temperature detection signal. For example, the temperature detection component 35 may be a temperature sensor disposed on the third pipe section 23 and used to detect the temperature of the rinsing solution within the third pipe section 23.
[0055] The aforementioned heating element 32 and temperature detection element 35 are both communicatively connected to the control element 36. For example, the control element 36 may be a controller, and a mounting cavity located below the heating element 32 may be provided within the base 34. The control element 36 may be disposed within the mounting cavity to optimize the structural design of the entire heating unit 30 as much as possible.
[0056] Based on the above configuration, when heating the flushing solution in the second pipe section 22, the temperature detection component 35 can detect the temperature of the flushing solution flowing through the second pipe section 22 in real time. The temperature detection component 35 can convert the detected temperature information into a temperature detection signal and send it to the control component 36. The control component 36 can respond to the temperature detection signal sent by the temperature detection component 35 and control the operation of the heating component 32 according to the temperature detection signal. For example, the control component 36 can control the output power of the heating component 32 according to the temperature detection signal, thereby controlling the temperature of the heat-conducting medium in the heating chamber 33, so that the temperature of the flushing solution flowing out of the second pipe section 22 and heated can be maintained within the target temperature range.
[0057] Furthermore, the heating unit 30 may also include a display unit 37 communicatively connected to the control unit 36. The display unit 37 displays the temperature of the rinsing solution after flowing through the second pipe section 22, as detected by the temperature detection unit 35, thereby facilitating real-time observation of the temperature of the rinsing solution after flowing through the second pipe section 22. For example... Figure 2 As shown, the display component 37 can be a display screen mounted on the outer wall of the base 34.
[0058] Combination Figure 2 As shown, the heating unit 30 may further include a connecting member 38, which may be disposed on the housing 31 and defines a slot 381 with an opening. It is understood that the connecting member 38 facilitates the temporary fixation of the entire heating unit 30 to a carrier such as an IV stand when the liquid storage container 10 is suspended on such a carrier, by having the slot 381 of the connecting member 38 engage with the carrier. The connecting member 38 may have a structure substantially similar to a clamp, and a detachable fastener 382, such as a bolt, may be provided at the opening of the slot 381 to improve the stability of the connecting member 38 when it is engaged with the IV stand.
[0059] Combination Figure 3 As shown, the housing 31 can be a generally cylindrical structure, and its circumferential sidewalls can be a double-layered structure. The circumferential sidewalls of the housing 31, from the inside out, include an inner layer 311 and an outer layer 312, with the inner layer 311 defining the heating cavity 33. The inner layer 311 can be made of thermal insulation material, and the outer layer 312 can be made of heat-insulating material. It is understood that by providing an inner layer 311 made of thermal insulation material, the time required for the heating element 32 to heat the heat-conducting medium in the heating cavity 33 to a suitable temperature is shortened, and the heat-conducting medium in the heating cavity 33 can be maintained within a certain temperature range for a longer period. The outer layer 312 made of heat-insulating material prevents the outer wall of the housing 31 from becoming too hot.
[0060] Continue to refer to Figure 3 The top of the housing 31 may also be provided with an inlet and outlet communicating with the heating chamber 33, and the inlet and outlet are provided with a sealing cover 39 for opening or closing the inlet and outlet. The sealing cover 39 may be a component threadedly connected to the top of the housing 31. Through the inlet and outlet and the sealing cover 39, when the sealing cover 39 is installed on the housing 31, it can seal the inlet and outlet of the heating chamber 33, thereby preventing the heat transfer medium from flowing out of the heating chamber 33. Correspondingly, when it is necessary to replenish the heat transfer medium into the heating chamber 33 or to perform maintenance or repair on the components inside the heating chamber 33, it is only necessary to remove the sealing cover 39.
[0061] Understandably, the closed-loop irrigation method requires repeated bladder irrigation. That is, after each irrigation, the waste fluid containing the irrigation solution in the bladder needs to be drained first, and then the irrigation solution is delivered to the bladder for the next irrigation. This process is repeated until the irrigation is completed.
[0062] Therefore, in combination Figure 1 and Figure 2 As shown, the heated flushing device disclosed in this embodiment may further include a three-way tube 60 and a drainage tube 70 with a switch. The first port of the three-way tube 60 is connected to the output end of the guide tube 20 (i.e., the end of the third tube segment 23 furthest from the second tube segment 22), the second port of the three-way tube 60 is connected to the catheter 40, the third port of the three-way tube 60 is connected to one end of the drainage tube 70, and the other end of the drainage tube 70 can be connected to a drainage bag (not shown in the figure).
[0063] Thus, during the bladder irrigation stage, the drainage tube 20 can be opened and the drainage tube 70 closed first, so that the irrigation solution from the reservoir 10 can flow sequentially through the drainage tube 20, the three-way tube 60, and the urinary catheter 40 to reach the patient's bladder for irrigation. After a single irrigation is completed, the drainage tube 20 is clamped and the drainage tube 70 is opened, and then the waste fluid containing the irrigation solution in the patient's bladder can be discharged. The waste fluid can flow sequentially through the urinary catheter 40, the three-way tube 60, and the drainage tube 70 into the drainage bag to achieve waste fluid collection and treatment.
[0064] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
