Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a portable peritoneal dialysis device. Background Technology

[0002] Peritoneal dialysis plays a crucial role in clinical practice as an important renal replacement therapy for patients with end-stage renal disease. During peritoneal dialysis, heating the dialysate to approximately 37°C, a comfortable temperature for the human body, is essential. This step not only improves patient comfort but also effectively avoids a series of complications caused by low-temperature infusion. Therefore, the heating device, as a core component of peritoneal dialysis equipment, directly impacts the overall user experience through its performance and structural design. Most peritoneal dialysis devices currently on the market use a fixed, integrated heating plate as the heating component. While this traditional design meets basic heating needs, it results in a large overall size, making it particularly inconvenient for home treatment settings. For end-stage renal disease patients who require frequent movement or rely on home treatment, lightweight and portable devices are key factors affecting their treatment experience and quality of life. Traditional devices, due to their size limitations, struggle to adapt to the diverse treatment scenarios required by patients, exhibiting significant shortcomings in both portability and home placement. Therefore, developing a portable peritoneal dialysis device that can ensure efficient and stable heating while effectively reducing its size through innovative structural design has become a crucial issue that urgently needs to be addressed in this field. This direction of improvement will not only enhance the convenience of treatment for patients but also promote the development of peritoneal dialysis treatment towards a more flexible and humane approach, meeting the actual needs of patients for mobile treatment devices in the modern medical environment.

Detailed Implementation

[0017] Example

[0018] Figures 1 to 4 The diagram shown is a structural schematic of one embodiment of a portable peritoneal dialysis device according to the present invention. Its main body includes a device housing 100, a heating tray 200, and a foldable support device 300. The foldable support device 300 includes a support plate 310 and a folding assembly 320 for controlling the unfolding or folding action of the support plate 310.

[0019] The device housing 100 is specifically a peritoneal dialysis device housing. The top of the device housing 100 is used to mount the gas tray 200, and one side is connected to the foldable support device 300. One side wall of the device housing 100 is recessed inwards at the support plate 310, forming a storage groove 140 that fits the support plate 310. When the support plate 310 is in the retracted state, it is located within the storage groove 140. A display screen and a power on / off button are provided at the front end of the device housing 100.

[0020] The top of the heating tray 200 is used to place the dialysis fluid bag for treatment. The heating tray 200 has a built-in heating element. In this embodiment, the heating element is a heating film. The heating tray 200 is made of aluminum alloy. The heating film is attached to the back of the heating tray 200 for heating the liquid in the dialysis fluid bag.

[0021] The foldable support device 300 includes a support plate 310 and a folding assembly 320 for controlling the unfolding or folding action of the support plate 310. When the support plate 310 is in the unfolded state, it supports the tail of the dialysate bag and is rotatably connected to one side of the device housing 100. In this embodiment, two sets of folding assemblies 320 are provided and symmetrically arranged at both ends of the support plate 310. During the treatment process, the support plate 310 is adjusted to the unfolded state by the folding assembly 320. At this time, the support plate 310 and the heating tray 200 form a continuous support plane, and the dialysate bag is then placed on the heating tray 200 and the support plate 310. After the treatment is completed, the support plate 310 is adjusted to the folded state by the folding assembly 320, and the folded support plate 310 is fitted against the side of the device housing 100 for storage.

[0022] Specifically, in this embodiment, such as Figure 3 , Figure 4 As shown, the folding assembly 320 includes a first fixing seat 3210 connected to the inner wall of the device housing 100 and a second fixing seat 3220 connected to the bottom of the support plate 310. A first connecting rod 3230, a second connecting rod 3240 and an elastic reset element 3250 are also connected between the two fixing seats. The upper end of the device housing 100 on one side of the support plate 310 is provided with a strip-shaped through hole 110. One end of the first connecting rod 3230 and the second connecting rod 3240 are respectively hinged to the first fixing seat 3210, and the other end of the first connecting rod 3230 and the second connecting rod 3240 respectively pass through the strip-shaped through hole 110 and are hinged to the second fixing seat 3220. In this embodiment, the length of the first connecting rod 3230 is less than the length of the second connecting rod 3240. The elastic reset element 3250 is a tension spring or a spring. Connecting ears are respectively provided on the first fixed seat 3210 and the second fixed seat 3220. The two ends of the elastic reset element 3250 are respectively connected to the connecting ears. In order to improve the stability of the support plate 310, two rods can be provided.

[0023] In use, gently push the end of the support plate 310 away from the heating tray 200 upwards at a 90-degree angle, causing the second fixing seat 3220 to rotate 90 degrees clockwise. This causes the first connecting rod 3230 and the second connecting rod 3240 to move synchronously, and the elastic reset element 3250 changes from a stretched state to a compressed state. The included angle between the first connecting rod 3230 and the second connecting rod 3240 increases, and the support plate 310 is in an unfolded state. When gently push the end of the support plate 310 away from the heating tray 200 downwards at a 90-degree angle, the second fixing seat 3220 rotates 90 degrees in the opposite direction, causing the first connecting rod 3230 and the second connecting rod 3240 to move synchronously. The elastic reset element 3250 changes from a compressed state to a stretched state, and the included angle between the first connecting rod 3230 and the second connecting rod 3240 decreases, and the support plate 310 is in a folded state. When the support plate 310 is folded and stored, it reduces the overall length of the peritoneal dialysis device by 5-6 cm, keeping the overall size of the device within 33.4cm × 33.3cm × 19.3cm. Compared to the size of existing peritoneal dialysis devices on the market (46cm × 38.5cm × 20.6cm), this significantly reduces the overall size of the device and improves the convenience of home and mobile peritoneal dialysis treatment. Furthermore, when the support plate 310 is unfolded, it only supports the tail of the dialysate bag, so it does not affect the heating of the liquid inside the dialysate bag.

[0024] like Figure 2 , Figure 5 As shown, in this preferred embodiment, to prevent liquid from entering the device through the strip-shaped through-hole 110 at the top of the device housing 100 and damaging the internal electronic components, a receiving cavity 120 is provided inside the device housing 100 to accommodate the first fixing seat 3210. The receiving cavity 120 and the inner wall of the device housing 100 together form a water storage cavity. A guide hole 130 communicating with the receiving cavity 120 is provided on the device housing 100 at the lower end of the receiving cavity 120. If liquid enters, it will accumulate in the water storage cavity and eventually flow out from the guide hole 130, further ensuring the safety of the device treatment.

[0025] like Figure 1 , Figure 2As shown, preferably, in this embodiment, in order to detect the temperature of the liquid inside the dialysis bag placed on top of the heating tray 200, a temperature sensor 400 is provided on one end surface of the heating tray 200 that protrudes outward from the surface of the heating tray 200. In use, the aluminum alloy surface of the temperature sensor 400 is embedded in the dialysis bag (outer surface of the dialysis bag). The temperature sensor 400 continuously monitors the temperature of the liquid inside the dialysis bag. When the detected temperature is 36~38°C, the liquid is then infused into the patient's peritoneal cavity to avoid discomfort or complications caused by low temperature. When the detected temperature exceeds 38°C, the temperature sensor 400 transmits the detected data to the device control unit, which then controls the clamping valve to close the tubing. Example

[0026] like Figure 1 , Figure 7 As shown, in Example 2, based on Example 1, to maximize the use of gravity-assisted dialysis fluid flow, reduce air bubble retention, and ensure complete drainage of residual dialysis fluid after treatment, thereby reducing the risk of microbial growth due to fluid retention, the plane on which the dialysis fluid bag is placed is designed as an inclined structure. The top of the device housing 100 has a gradually decreasing inclined mounting surface from the end near the support plate 310 to the end away from the support plate 310. The heating tray 200 is inclined along this mounting surface. The bottom plane of the support plate 310 gradually decreases from the end away from the heating tray 200 to the hinge end, forming a compensating tilt angle. When the support plate 310 is in the unfolded state, the support plate 310 and the heating tray 200 combine to form a continuously inclined (gradually decreasing) support plane. In this embodiment, the angle α between the continuously inclined support plane and the horizontal plane is 3~15°, more preferably 3~8°, to prevent the tilt angle from being too large, causing the dialysis fluid bag to slip and accumulate at the lowest point of the heating tray 200.

[0027] like Figure 2 , Figure 8 As shown, in this preferred embodiment, to prevent the dialysate bag from slipping off the heating tray 200, an upwardly extending baffle 150 is provided at the edge of the inclined mounting surface of the device housing 100. The baffle 150 forms a pipe notch 160 at the lowest end of the inclined mounting surface for placing the pipe connected to the dialysate bag. In addition, limiting flanges 3110 are provided at both ends of the support plate 310, and the limiting flanges 3110 form an arc transition with the top of the support plate 310, further limiting the dialysate bag.

[0028] Combination Figures 1 to 8 The portable peritoneal dialysis device of this embodiment is used in the following specific way: When a patient needs treatment, the support plate 310 stored on one side of the device housing 100 is first unfolded, and then the dialysis bag is placed on the heating tray 200 and the top of the support plate 310. The peritoneal dialysis device is then started to begin treatment. After treatment, the support plate 310 is stored on one side of the device housing 100 through the folding component 320, which enables the support plate 310 to be quickly unfolded and folded. The structure is simple, the operation is convenient, and the support stability is good. It significantly reduces the overall volume of the peritoneal dialysis device and improves the convenience of home and mobile peritoneal dialysis treatment.
