Description

Technical Field

[0001] This invention belongs to the field of medical technology, and in particular relates to a heating pack for neonatal peritoneal dialysis fluid. Background Technology

[0002] Neonatal peritoneal dialysis is a common emergency treatment for neonatal acute renal failure. During peritoneal dialysis, the dialysate needs to be heated to approximately 37°C to prevent hypothermia. Traditionally, peritoneal dialysis is added via a water bath, but this method cannot guarantee continuous and effective heating of the dialysate. Since the peritoneal dialysis solution currently used in the medical field is in 2L / bag form, a newborn only needs a maximum of one bag for 24 hours of dialysis. If the dialysate is heated beforehand and then exposed to the outside environment for 24 hours, its temperature will drop rapidly, which is detrimental to maintaining the newborn's body temperature and circulatory stability. Heating the infusion tubing connected to the dialysis tubing with a heating rod has limited heating effect; therefore, a neonatal peritoneal dialysis solution heating pack is necessary.

[0003] Chinese Patent (CN109646745A) discloses a dialysis fluid heating device for CRRT, including a heating device and a vibration device. The heating device includes a heating plate, a heating tube, and two rectangular heating bases arranged parallel to each other. The two heating bases are connected around their perimeter by a foldable connecting fabric to form a heating cavity. A straight opening for inserting a dialysis bag is provided at one end of the connecting fabric along the length of the heating base. Heating plates are provided on opposite surfaces of the two heating bases, and heating tubes are located inside the heating plates. The vibration device includes a vibration base. The base is equipped with a vibrator that passes through the heating base and heating plate, then extends into the heating cavity and contacts the surface of the dialysis bag to be heated. Although current dialysis fluid heating devices can also heat the dialysis fluid, the heating rate can only be controlled by temperature control. However, since the dialysis fluid is usually contained in the dialysis bag, there is generally a temperature limit during the heating process. Exceeding the temperature limit can easily damage the dialysis bag, resulting in low overall heating efficiency and limited effectiveness. To solve these problems, there is an urgent need for a neonatal peritoneal dialysis fluid heating pack. Summary of the Invention

[0004] The purpose of this invention is to address the problem that while current dialysis fluid heating devices can heat the dialysis fluid, the heating rate can only be controlled by temperature. However, since the dialysis fluid is generally contained in a dialysis bag, there is usually a temperature limit during the heating process. Exceeding this temperature limit can easily damage the dialysis bag, resulting in low overall heating efficiency and limited effectiveness. Therefore, this invention proposes a neonatal peritoneal dialysis fluid heating pack.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a neonatal peritoneal dialysis fluid heating pack, comprising an outer pack, a top cover mounted on the top of the outer pack via a hinge, a heating tube embedded in the bottom cavity of the outer pack, a drive motor fixedly mounted on one side of the outer wall of the outer pack, a placement mechanism fixedly mounted on one end of the output shaft of the drive motor for placing the dialysis fluid pack, a turbulence-inducing component rotatably mounted inside the outer pack for turbulent airflow within the outer pack, and a precision volume control pump fixedly mounted on the other side of the outer wall of the outer pack, an inlet pipe provided at one end of the precision volume control pump, and a suction hose fixedly mounted at the other end of the inlet pipe.

[0006] As a further description of the above technical solution:

[0007] The storage mechanism includes a mounting shaft, one end of which is fixedly mounted with a storage shell, and a drive pulley is fixedly mounted on the outside of the mounting shaft. The storage shell has a storage cavity inside, and a load-bearing component is disposed inside the storage cavity.

[0008] As a further description of the above technical solution:

[0009] The supporting component includes a supporting plate, and side sliders are fixedly installed on both outer walls of the supporting plate. One end of the side slider is slidably connected to a groove provided on the inner surface of the storage cavity, and a pressure spring is fixedly installed on the bottom surface of the side slider.

[0010] As a further description of the above technical solution:

[0011] The bottom end of the pressure spring is fixedly connected to the inner wall of the bottom surface of the slide groove, and a limit pin is fixedly installed longitudinally on the top surface of the side slider. A first roller is rotatably installed in the top groove on the top surface of the bearing plate via a rotating shaft.

[0012] Furthermore, by incorporating a support component and a pressing component within the placement mechanism, the pressure on the support plate increases after the dialysate pack is placed inside. As the amount of dialysate pack placed on the support plate increases, the pressure on the support plate also gradually increases. When the pressure exceeds the bearing capacity of the pressure spring, the support plate gradually descends, simultaneously causing the limit pin to descend. This causes one end of the limit pin to disengage from the bottom locking hole of the pressing component. At this point, the side spring pushes out the pressing shell, and both pressing shells pop out simultaneously, sealing the upper part of the placement cavity. This allows the heat entering the placement cavity to be reflected by the heat reflector plate of the pressing component, reconcentrating the heat inside the placement cavity, thereby further improving the heating efficiency of the dialysate pack. Through this design, the upper part of the placement cavity can be automatically sealed when loading the dialysate pack, improving heat reflection efficiency and thus further enhancing the heating efficiency of the heating pack.

[0013] As a further description of the above technical solution:

[0014] The storage shell has side mounting grooves in its two side cavities. A pressing assembly is provided inside the side mounting groove. The pressing assembly includes a pressing shell. The bottom surface of the pressing shell has a bottom locking hole and an inner mounting groove. One end of the limiting locking shaft is inserted into the bottom locking hole. A side top spring is fixedly installed on one side outer wall of the pressing shell. One end of the side top spring is fixedly connected to one side inner wall of the side mounting groove.

[0015] As a further description of the above technical solution:

[0016] A spring shaft is fixedly installed inside the mounting groove. An inner shell is fixedly installed at one end of the spring shaft. A heat reflector is fixedly installed on the bottom surface of the inner shell. A second roller shaft is rotatably installed inside the inner shell via a mounting shaft. A spool is fixedly installed outside the mounting shaft.

[0017] As a further description of the above technical solution:

[0018] A longitudinal sliding rod is fixedly installed inside the inner shell, and a rod sleeve is slidably installed outside the longitudinal sliding rod. A pressure plate is fixedly installed at one end of the rod sleeve.

[0019] As a further description of the above technical solution:

[0020] The outer surface of the pressing disc is provided with several protrusions, and a connecting rope is wound around the outside of the reel. One end of the connecting rope is fixedly connected to one end of the rod sleeve.

[0021] Furthermore, by installing a second roller and a pressing plate inside the inner shell, after the pressing shell pops out, the spring shaft can automatically push the inner shell down, allowing the second roller to effectively contact the dialysate bag. Since several first rollers are also installed on the support plate, when the placement mechanism shakes, the dialysate bag will also move between the support plate and the inner shell. When the dialysate bag moves, it can drive the second roller to rotate, which can drive the spool to rotate synchronously. Thus, the spool can wind up the connecting rope, and the connecting rope can lift the rod sleeve, thereby lifting the pressing plate. When the second roller rotates, the pressing plate can automatically fall, achieving vertical pressing of the dialysate bag, which can effectively increase the flow rate of dialysate in the dialysate bag, thereby further improving the heating effect and efficiency of the dialysate bag.

[0022] As a further description of the above technical solution:

[0023] The turbulence assembly includes a blade shaft, and a driven pulley and turbulence blades are fixedly mounted on the outside of the blade shaft.

[0024] As a further description of the above technical solution:

[0025] The driven pulley and the driving pulley are connected by a transmission belt, and several ventilation holes are provided on the outer surface of the storage shell.

[0026] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0027] 1. In this invention, by incorporating a placement mechanism and a turbulence-inducing component, when heating the dialysate pack, the top cover is opened, the dialysate pack is placed into the placement mechanism, the top cover is closed, the heating element is turned on, causing the temperature inside the pack to rise rapidly, the drive motor is turned on, and the drive motor is controlled to rotate forward and backward, thereby controlling the placement mechanism to swing left and right, effectively shaking the dialysate pack placed inside the placement mechanism. Simultaneously, when the placement mechanism shakes, the drive pulley also rotates forward and backward, and the drive pulley can drive the driven pulley of the turbulence-inducing component to rotate forward and backward synchronously through the transmission belt, thereby causing the blade shaft and the turbulence blades to rotate synchronously. The turbulence blades rapidly turbulent the hot airflow inside the pack, allowing the hot airflow to quickly enter the placement mechanism and rapidly heat the dialysate pack that is shaking in real time. Through this design, the dialysate pack can be shaken in real time, while the hot air circulation rate inside the pack can be increased, increasing the contact area between the hot air and the dialysate pack, thereby improving the dialysate heating efficiency.

[0028] 2. In this invention, by providing a support component and a pressing component within the placement mechanism, the pressure borne by the support plate increases after the dialysate pack is placed into the placement mechanism. As the amount of dialysate pack placed on the support plate increases, the bearing pressure on the support plate also gradually increases. When the pressure exceeds the bearing capacity of the pressure spring, the support plate gradually descends, simultaneously driving the limiting pin to descend, causing one end of the limiting pin to disengage from the bottom locking hole of the pressing component. At this time, the side spring pushes out the pressing shell, and both pressing shells pop out simultaneously, which can seal the upper part of the placement cavity. This allows the heat entering the placement cavity to be reflected by the heat reflector plate of the pressing component, causing the heat to be reconcentrated inside the placement cavity, thereby further improving the heating efficiency of the dialysate pack. Through this design, the upper part of the placement cavity can be automatically sealed when loading the dialysate pack, improving the heat reflection efficiency and thus further improving the heating efficiency of the heating pack.

[0029] 3. In this invention, by providing a second roller and a pressing plate inside the inner shell, after the pressing shell pops out, the spring shaft can automatically push the inner shell down, allowing the second roller to effectively contact the dialysis bag. Since several first rollers are also provided on the support plate, when the placement mechanism shakes, the dialysis bag will also move between the support plate and the inner shell. When the dialysis bag moves, it can drive the second roller to rotate, which can drive the spool to rotate synchronously. Thus, the spool can wind up the connecting rope, and at this time, the connecting rope can lift the rod sleeve, thereby lifting the pressing plate. When the second roller rotates, the pressing plate can automatically fall down, realizing... The top and bottom compression of the dialysis bag effectively increases the flow rate of the dialysis fluid within the bag, further enhancing its heating effect and efficiency. The device is equipped with a precision volume control pump and a suction hose. During use, the suction hose is connected to the dialysis bag, continuously heating it for 24 hours to maintain a consistent temperature. The precision volume control pump precisely controls the amount of dialysis fluid extracted, reducing frequent changes and preventing neonatal hypothermia and infection. Furthermore, the internal temperature of the device can be continuously monitored for temperature control. Attached Figure Description

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figure 1-8 This invention provides a technical solution: a neonatal peritoneal dialysis fluid heating pack, comprising an outer package 2, a top cover 1 mounted on the top of the outer package 2 via a hinge, a heating tube embedded in the bottom cavity of the outer package 2, a drive motor 3 fixedly mounted on one side of the outer wall of the outer package 2, a placement mechanism 4 fixedly mounted on one end of the output shaft of the drive motor 3 for placing the dialysis fluid pack, a turbulence-inducing component 5 rotatably mounted inside the outer package 2 for turbulence of hot air inside the outer package 2, and a precision volume control pump 7 fixedly mounted on the other side of the outer wall of the outer package 2, an inlet pipe provided at one end of the precision volume control pump 7, and a suction hose 8 fixedly mounted at one end of the inlet pipe.

[0042] The storage mechanism 4 includes a mounting shaft 41, one end of which is fixedly mounted with a storage shell 43. A drive pulley 42 is fixedly mounted on the outside of the mounting shaft 41. The storage shell 43 has an internal storage cavity 44, and a support assembly 46 is disposed inside the internal storage cavity 44. The support assembly 46 includes a support plate 464, and side sliders 462 are fixedly mounted on both outer walls of the support plate 464. One end of each side slider 462 is slidably connected to a groove on the inner surface of the internal storage cavity 44. A pressure spring 463 is fixedly mounted on the bottom surface of each side slider 462, and the bottom end of the pressure spring 463 is fixedly connected to the inner wall of the bottom surface of the groove. A limiting pin 461 is longitudinally fixedly installed on the top surface of block 462. A first roller 465 is rotatably installed in the top groove on the top surface of the bearing plate 464 via a rotating shaft. Side mounting grooves 45 are provided in the two side cavities of the storage shell 43. A pressing assembly 47 is provided inside the side mounting groove 45. The pressing assembly 47 includes a pressing shell 475. A bottom locking hole 472 and an inner mounting groove 473 are provided on the bottom surface of the pressing shell 475. One end of the limiting pin 461 is inserted into the bottom locking hole 472. A side top spring 474 is fixedly installed on one side outer wall of the pressing shell 475. One end of the side top spring 474 is fixedly connected to one side inner wall of the side mounting groove 45.

[0043] The specific implementation method is as follows: After the dialysate package is placed into the storage mechanism 4, the pressure on the support plate 464 will increase. As the amount of dialysate package placed on the support plate 464 increases, the bearing pressure on the support plate 464 will also gradually increase. When the pressure is greater than the bearing capacity of the pressure spring 463, the support plate 464 will gradually descend, simultaneously driving the limit pin 461 to descend, so that one end of the limit pin 461 disengages from the bottom bottom pin hole 472 of the pressing assembly 47. At this time, the side top spring 474 pushes out the pressing shell 475. The two pressing shells 475 pop out at the same time, which can seal the top of the storage cavity 44, so that the heat entering the storage cavity 44 can be reflected by the heat reflector plate 476 of the pressing assembly 47, so that the heat is reconcentrated inside the storage cavity 44, thereby further improving the heating efficiency of the dialysate package.

[0044] This design enables the upper part of the inner cavity 44 to be automatically sealed when loading the dialysis fluid pack, improving heat reflection efficiency and thus further enhancing the heating efficiency of the heating pack.

[0045] A spring shaft 4715 is fixedly installed inside the mounting groove 473. An inner shell 471 is fixedly installed at one end of the spring shaft 4715. A heat reflector plate 476 is fixedly installed on the bottom surface of the inner shell 471. A second roller shaft 477 is rotatably installed inside the inner shell 471 via a mounting shaft 4710. A spool 479 is fixedly installed outside the mounting shaft 4710. A longitudinal sliding rod 4713 is fixedly installed longitudinally inside the inner shell 471. A rod sleeve 4714 is slidably installed outside the longitudinal sliding rod 4713. A pressure plate 478 is fixedly installed at one end of the rod sleeve 4714. Several protrusions 4712 are provided on the outer surface of the pressure plate 478. A connecting rope 4711 is wound around the outside of the spool 479. One end of the connecting rope 4711 is fixedly connected to one end of the rod sleeve 4714.

[0046] The specific implementation method is as follows: After the pressing shell 475 pops out, the spring shaft 4715 can automatically push the inner shell 471 down, so that the second roller shaft 477 can effectively contact the dialysate bag. Since several first roller shafts 465 are also provided on the support plate 464, when the placement mechanism 4 shakes, the dialysate bag will also move between the support plate 464 and the inner shell 471. When the dialysate bag moves, it can drive the second roller shaft 477 to rotate. The second roller shaft 477 can drive the filament wheel 479 to rotate synchronously, so that the filament wheel 479 can realize the winding of the connecting rope 4711. At this time, the connecting rope 4711 can lift the sleeve 4714, thereby lifting the pressing plate 478. When the second roller shaft 477 flips, the pressing plate 478 can automatically fall, realizing the upper and lower pressing of the dialysate bag, thereby effectively improving the flow rate of dialysate in the dialysate bag, and further improving the heating effect and efficiency of the dialysate bag.

[0047] The turbulence assembly 5 includes a blade shaft 53, on the outside of which a driven pulley 52 and a turbulence blade 51 are fixedly mounted. The driven pulley 52 and the drive pulley 42 are connected by a transmission belt. Several ventilation holes are provided on the outer surface of the housing 43.

[0048] The specific implementation method is as follows: When heating the dialysate pack, open the top cover 1, place the dialysate pack into the placement mechanism 4, close the top cover 1, turn on the heating element to rapidly raise the temperature inside the outer pack 2, turn on the drive motor 3, and control the drive motor 3 to rotate forward and reverse, thereby controlling the placement mechanism 4 to swing left and right, so that the dialysate pack placed in the placement mechanism 4 can be effectively shaken. At the same time, when the placement mechanism 4 shakes, the drive pulley 42 will also rotate forward and reverse. The drive pulley 42 can drive the driven pulley 52 of the turbulence component 5 to rotate forward and reverse synchronously through the transmission belt, so that the blade shaft 53 and the turbulence component 5 can rotate in tandem. The flow vanes 51 rotate synchronously, and the turbulence vanes 51 rapidly turbulent the hot airflow inside the outer casing 2. The hot airflow can quickly enter the storage mechanism 4 to rapidly heat the dialysate bag that is shaking in real time. When using the equipment, the suction tubing 8 is connected to the dialysate bag to continuously heat the dialysate bag for 24 hours to maintain a certain temperature. During use, the amount of dialysate extracted can be precisely controlled by the volume control pump 7 to reduce the frequency of dialysate replacement and avoid neonatal hypothermia and infection. In addition, the temperature inside the equipment can be continuously monitored during this process to facilitate temperature control.

[0049] This design allows the dialysate pack to be shaken in real time, while also increasing the flow rate of hot air inside the pack and increasing the contact area between the hot air and the dialysate pack, thereby improving the dialysate heating efficiency.

[0050] Working principle: When heating the dialysate bag, open the top cover 1, place the dialysate bag into the placement mechanism 4, close the top cover 1, turn on the heating element to rapidly raise the temperature inside the outer bag 2, turn on the drive motor 3, and control the forward and reverse rotation of the drive motor 3 to control the placement mechanism 4 to swing left and right, effectively shaking the dialysate bag placed inside the placement mechanism 4. At the same time, when the placement mechanism 4 shakes, the drive pulley 42 also rotates forward and reverse. The drive pulley 42 drives the driven pulley 52 of the turbulence assembly 5 to rotate forward and reverse synchronously through the transmission belt, thereby causing the blade shaft 53 and the turbulence blade 51 to rotate synchronously. The turbulence blade 51 rapidly turbulents the hot airflow inside the outer bag 2. It can quickly enter the storage mechanism 4 to rapidly heat the dialysate pack that is being shaken in real time. While heating the dialysate pack, the top cover 1 is opened, the dialysate pack is placed into the storage mechanism 4, the top cover 1 is closed, the heating element is turned on to rapidly raise the temperature inside the outer pack 2, the drive motor 3 is turned on, and the drive motor 3 is controlled to rotate forward and backward, thereby controlling the storage mechanism 4 to swing left and right, effectively shaking the dialysate pack placed inside. Simultaneously, when the storage mechanism 4 shakes, the drive pulley 42 also rotates forward and backward. The drive pulley 42, through the transmission belt, drives the driven pulley 52 of the turbulence assembly 5 to rotate synchronously forward and backward, thereby causing the blade shaft 53 and the turbulence blades 51 to rotate synchronously. The turbulence vane 51 rapidly turbulents the hot airflow inside the outer casing 2, allowing the hot airflow to quickly enter the placement mechanism 4 and rapidly heat the dialysate packs that are constantly shaking. After the dialysate packs are placed into the placement mechanism 4, the pressure on the support plate 464 increases. As the number of dialysate packs placed on the support plate 464 increases, the pressure on the support plate 464 also gradually increases. When the pressure exceeds the bearing capacity of the pressure spring 463, the support plate 464 gradually descends, simultaneously driving the limit pin 461 to descend, causing one end of the limit pin 461 to disengage from the bottom locking hole 472 of the pressing assembly 47. At this time, the side top spring 474 pushes out the pressing shell 475, and the two pressing shells 475... Simultaneously, the device pops out, sealing the top of the inner cavity 44. This allows heat entering the inner cavity 44 to be reflected by the heat reflector 476 of the pressing component 47, concentrating the heat back into the inner cavity 44. This further improves the heating efficiency of the dialysis fluid bag. When using the device, the suction tubing 8 is connected to the dialysis bag, continuously heating the dialysis fluid bag for 24 hours to maintain a constant temperature. During use, the volume of dialysis fluid extracted can be precisely controlled by the precision volume control pump 7, reducing the frequency of dialysis fluid replacement and preventing neonatal hypothermia and infection. Furthermore, the temperature inside the device can be continuously monitored during this process for temperature control.

[0051] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
