Description

Technical Field

[0001] The invention relates to the technical field of nursing, and in particular to a wearable peritoneal dialysis nursing training device. Background Art

[0002] Peritoneal dialysis (PD), also known as peritoneal dialysis, is one of the main renal replacement therapies for end-stage renal disease (ESRD). It is inexpensive and easy to operate, and patients and their families can perform dialysis treatment at home. Home peritoneal dialysis breaks the traditional medical model in which patients rely on hospitals and medical staff for treatment. It has great flexibility and autonomy, and improves the quality of life of patients. However, patients need to go home for dialysis operations, which often cause peritonitis due to improper operation. Peritonitis is one of the important complications of peritoneal dialysis, the main cause of patient withdrawal from PD and death, and directly affects the dialysis efficacy of patients. Most home peritoneal dialysis operators are non-medical personnel, and their operational standardization is closely related to the occurrence of peritonitis. Therefore, standardized peritoneal dialysis operation training is carried out for home peritoneal operators. The current training materials are mainly based on videos, pictures, and part models, which are relatively mechanical and boring, and lack interaction with patients. Wear the wearable membrane peritoneal dialysis nursing training mold on the role-playing patient or patient for demonstration and education. At the same time, when the patient was operating at home, due to the non-standard preliminary operation process, he forgot to check whether the peritoneal dialysis bag was leaking, which caused the patient to be infected. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention proposes a wearable peritoneal dialysis nursing training device to solve the technical problems mentioned in the above background technology that the traditional training materials lack interactivity with patients and that patients may be infected due to early non-standard operations when operating at home.

[0004] In order to solve this technical problem, the technical solution adopted by the present invention is:

[0005] A wearable peritoneal dialysis nursing training device, used for training connection of peritoneal dialysis bags, comprising a belt body, a pressing plate, a disinfectant, a catheter bag, a pushing spring, a limit assembly and an operating mechanism;

[0006] The belt body can be tied to the patient, and a plurality of mounting grooves are provided on the belt body. The mounting grooves correspond to each other and are respectively provided with the pressing plate, the disinfectant, or the catheter bag. The pressing plate, the catheter bag, and the disinfectant are respectively connected to the bottom surface of the mounting groove through the pushing spring. The limiting assembly is provided in the mounting groove and can limit the pressing plate, the disinfectant, or the catheter bag in the mounting groove.

[0007] The operating mechanism is arranged on the belt body and is respectively connected to each of the limiting components. Repeatedly pressing the operating mechanism can rotate the limiting components where the pressing plate, the disinfectant and the catheter bag are located in turn, and release the limiting of the pressing plate, the disinfectant or the catheter bag.

[0008] As can be seen from the above, by tying the device to the patient, the patient can participate more in the training process during the operation. At the same time, through the operating mechanism of the device, the pressing plate can be popped out when pressed for the first time, which reminds the operator to press the peritoneal dialysis bag on the pressing plate to check whether the peritoneal dialysis bag is leaking; after pressing and checking, the operating mechanism is pressed for the second time, and the disinfectant is popped out to remind the operator to disinfect his hands; after hand disinfection, the operating mechanism is pressed again to make the catheter bag pop out, so that the peritoneal dialysis catheter in the catheter bag can be connected to the dual system of the peritoneal dialysis bag to perform peritoneal dialysis. By repeatedly simulating the operation process before connecting the peritoneal dialysis bag in a fixed order, the operator can clearly know each step of the operation and reduce the risk of infection for the patient.

[0009] Furthermore, the operating mechanism includes a fixed box, a pushing guide box, a pushing assembly, a rotating assembly, a ratchet assembly, a transmission assembly, a transmission guide box, a connecting box and a connecting assembly.

[0010] The fixing box is arranged on the belt body, and a cavity is arranged inside the fixing box, and a through hole connected to the cavity is arranged at one end of the fixing box.

[0011] The pushing guide box is arranged on the inner wall of the fixed box, and a first limiting slide groove is arranged on the pushing guide box. The rotating component is rotatably arranged in the cavity of the fixed box; the pushing component is slidably connected to the through hole of the fixed box and abuts against the inner bottom surface of the first limiting slide groove. Pushing the pushing component can make it slide from one side of the first limiting slide groove to the other side and drive the rotating component to rotate. Then pulling back the pushing component can make the pushing component slide on the first limiting slide groove in a direction away from the rotating component and return to an initial position.

[0012] The transmission guide box is arranged on the inner wall of the fixed box and is opposite to the pushing guide box, and a second limiting slide groove is arranged on the transmission guide box; the transmission component is slidably connected to the inner wall of the fixed box and abuts against the inner bottom surface of the second limiting slide groove; the connecting box is arranged on the inner wall of the fixed box and is provided with three slide grooves, and the connecting component corresponds to the slide grooves and the limiting component one by one, and the connecting component is slidably connected in the slide grooves respectively and is connected to the limiting component; the ratchet component is arranged on the rotating component and rotates together with the rotating component.

[0013] Repeatedly pushing the pushing assembly can cause the ratchet assembly to drive the transmission assembly to sequentially squeeze the connecting assembly, driving the pressing plate, the disinfectant, and the limiting assembly at the catheter bag to rotate. Through this mechanism, the pressing plate, the disinfectant, and the catheter bag can pop out in sequence, thereby strengthening the operator's operating steps.

[0014] Further, the pushing assembly includes a pushing block, a pushing reset spring, a pushing pressure rod and a pushing rack; the pushing block is slidably connected to the through hole on the fixed box and is connected to the fixed box through the pushing reset spring; the pushing pressure rod is hinged to the pushing block and abuts against the inner bottom surface of the first limiting slide groove; the pushing rack is arranged on the pushing pressure rod, pushing the pushing block, the pushing rack can mesh with the rotating assembly and drive the rotating assembly to rotate, and then pulling back the pushing block, the pushing block can move away from the rotating assembly and return to the initial position. Pushing the pushing block drives the pushing rack to drive the rotating assembly to rotate, and resets from the other side of the first limiting slide groove, so that a single push can cause the rotating assembly to rotate a fixed value.

[0015] Furthermore, the rotating assembly includes a rotating shaft and a pushing gear; the rotating shaft is rotatably connected to the inner wall of the fixed box, the pushing gear is coaxially arranged on the rotating shaft, and the pushing gear can mesh with the pushing rack. Through the cooperation of the pushing gear and the pushing rack, the pushing rack can better drive the pushing gear to rotate.

[0016] Furthermore, the ratchet assembly includes a ratchet body, a pawl and a ratchet spring; the ratchet body is coaxially fixed on the rotating shaft, the pawl is hinged to the inner wall of the fixed box and connected to the inner wall of the fixed box through the ratchet spring, the pawl can limit the rotation of the ratchet body; the ratchet can drive the transmission assembly to slide. By setting the ratchet body and the pawl of this structure, the ratchet body can maintain the previous state when it is not rotating, and will not be driven by the transmission assembly to rotate in the opposite direction.

[0017] Furthermore, the transmission assembly includes a transmission slider, a transmission spring, a transmission pressure rod, a ratchet connecting block and a transmission block; the transmission slider is slidably connected to the inner wall of the fixed box and is connected to the fixed box through the transmission spring; the transmission pressure rod abuts against the inner bottom surface of the second limiting slide groove, the ratchet connecting block is provided with three and is arranged on the transmission pressure rod, and the transmission block is arranged on the transmission pressure rod close to the transmission slider side, and a single rotation of the ratchet can drive one of the ratchet connecting blocks to slide, and cause the transmission block to squeeze the connecting assembly, so that the connecting assembly slides and drives the limiting assembly to rotate; repeatedly pushing the pushing block can cause the ratchet body to push the ratchet connecting block in turn, and cause the transmission block to squeeze the connecting assembly in turn, and after the ratchet body drives the transmission pressure rod to slide three times, it returns to its initial position along the second limiting slide groove under the action of the transmission spring. This structure enables a single rotation of the ratchet body to drive the ratchet connecting block to slide a certain distance, so that the transmission block can press the connecting component, so that the connecting component can drive the limit component to release the limit on the pressing plate, or the disinfectant, or the catheter bag, and after the transmission pressure rod slides three times through the ratchet connecting block, it returns to the initial position from another time of the second limiting slide groove.

[0018] Furthermore, the connecting assembly includes a beveled rack, a rotating shaft, a connecting gear, a connecting spring and a connecting rope; the beveled rack is slidably connected to the slide slot of the connecting box, and is connected to the slide slot of the connecting box through the connecting spring; the rotating shaft is rotatably connected to the slide slot of the connecting box, and is coaxially fixed with the connecting gear, the connecting gear is meshed with the beveled rack, one end of the connecting rope is connected to the rotating shaft, and the other end is connected to the limiting assembly; the transmission block can drive the beveled rack to slide, so that the connecting rope is gradually wound around the rotating shaft, and drives the limiting assembly to rotate. This structure causes the beveled rack to slide by being squeezed by the transmission block, and drives the connecting gear to rotate, and the rotation of the connecting gear drives the rotation of the rotating shaft, so that the connecting rope is gradually wound around the rotating shaft, thereby pulling the limiting assembly to rotate, and realizing the limiting of the pressing plate, or the disinfectant, or the catheter bag.

[0019] Furthermore, the limiting assembly includes a limiting plate and a limiting spring; one end of the limiting plate is hinged on the installation slot, and the other end abuts against the pressing plate, the disinfectant, or the catheter bag, and is connected to the installation slot through the limiting spring; the limiting plate is connected to the connecting rope, and the connecting rope can drive the limiting plate to rotate and release the limiting of the pressing plate, the disinfectant, or the catheter bag. The limiting plate itself is inclined in the installation slot due to the limiting spring, and rotates into the installation slot after being pulled by the connecting rope, and releases the limiting of the pressing plate, the disinfectant, or the catheter bag.

[0047] The following embodiments of the technical solution of the present invention are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and are therefore only used as examples, and cannot be used to limit the protection scope of the present invention.

[0048] Please also read Figure 1-Figure 9 The present invention provides a wearable peritoneal dialysis nursing training device for training connection of a peritoneal dialysis bag, comprising a belt body 1, a pressing plate 2, a disinfectant 3, a catheter bag 4, a pushing spring 5, a limiting component 6 and an operating mechanism 7.

[0049] See also Figure 1-Figure 2 , Figure 8-Figure 9The belt body 1 can be tied to the patient, and a plurality of mounting grooves 11 are provided on the belt body 1. The mounting grooves 11 correspond to each other and are respectively provided with a pressing plate 2, a disinfectant 3, or a catheter bag 4. The pressing plate 2, the catheter bag 4, and the disinfectant 3 are respectively connected to the bottom surface of the mounting groove 11 through a push spring 5. The limiting assembly 6 is provided in the mounting groove 11 and can limit the pressing plate 2, the disinfectant 3, or the catheter bag 4 in the mounting groove 11. It should be understood that the pushing spring 5 is in a compressed state before the limiting assembly 6 releases the pressing plate 2, the disinfectant 3, or the catheter bag 4. After the limiting assembly 6 releases its limiting effect, the pushing spring 5 ejects the pressing plate 2, the disinfectant 3, or the catheter bag 4. It should also be understood that the pressing plate 2 is a sterile plate, and its surface may be marked with words such as "sterile pressing plate" or "sterile pressing plate" to remind the operator to press and check the peritoneal dialysis bag on the pressing plate 2. At the same time, the catheter package 4 may include a peritoneal dialysis catheter and a sterile pad. The sterile pad is arranged on the peritoneal dialysis catheter. When the catheter package 4 is popped out, the sterile pad should be placed under the peritoneal dialysis catheter. After the peritoneal dialysis catheter and the dual system of the peritoneal dialysis bag are connected, the sterile pad should be wrapped around the peritoneal dialysis catheter.

[0050] See also Figure 1 and Figure 2 The operating mechanism 7 is arranged on the belt body 1 and is connected to each limiting assembly 6 respectively. Repeatedly pressing the operating mechanism 7 can rotate the limiting assembly 6 where the pressing plate 2, disinfectant 3 and catheter package 4 are located in turn, and release the limiting of the pressing plate 2, disinfectant 3 or catheter package 4. It should be understood that since the pressing plate 2, disinfectant 3 or catheter package 4 are suspended in the installation groove 11 due to being connected to the push spring 5, the limiting assembly 6 can rotate to the gap between the pressing plate 2, disinfectant 3, catheter package 4 and the installation groove 11 after rotation, so that the pressing plate 2, disinfectant 3 or catheter package 4 pops outward under the drive of the push spring 5. It should also be understood that after the pressing plate 2, disinfectant 3 and catheter package 4 are all popped out, they can be pressed back to the installation groove 11, and the limiting assembly 6 can be re-limited, and the operating mechanism 7 still rotates the limiting assembly 6 corresponding to it in the order of the pressing plate 2, disinfectant 3 and catheter package 4.

[0051] See also Figure 3-Figure 7 In other embodiments, the operating mechanism 7 includes a fixed box 71, a pushing guide box 72, a pushing assembly 73, a rotating assembly 74, a ratchet assembly 75, a transmission assembly 76, a transmission guide box 77, a connecting box 78 and a connecting assembly 79.

[0052] See also Figure 3-Figure 4 The fixing box 71 is arranged on the belt body 1, and the fixing box 71 has a cavity inside, and one end of the fixing box 71 is provided with a through hole connected to the cavity.

[0053] The pushing guide box 72 is arranged on the inner wall of the fixed box 71, and the pushing guide box 72 is provided with a first limiting sliding groove 721, and the rotating component 74 is rotatably arranged in the cavity of the fixed box 71; the pushing component 73 is slidably connected to the through hole of the fixed box 71, and abuts against the inner bottom surface of the first limiting sliding groove 721. Pushing the pushing component 73 can make it slide from one side of the first limiting sliding groove 721 to the other side, and drive the rotating component 74 to rotate, and then pulling back the pushing component 73 can make the pushing component 73 slide on the first limiting sliding groove 721 in the direction away from the rotating component 74 and return to the initial position. It should be understood that the first limited slot 721 includes two slots, and there is a height difference between the two slots at the connected place, that is, after the push component 73 slides from the first slot into the second slot, it cannot return to the first slot from the connected place due to the height difference and can only slide along the second slot. When the push component 73 slides from the second slot back to the first slot, it cannot return to the second slot from the connected place due to the height difference and can only slide back to the original position from the first slot; the first slot includes two vertical slots and an inclined slot connecting the two slots. When the push component 73 enters the vertical slot near the through hole of the fixed box 71, it starts to contact with the rotating component 74 and drives the rotating component 74, then slides into the second slot and moves away from the rotating component 74, and returns to the initial position from the second slot. It should also be understood that the push component 73 slides from the place away from the rotating component 74 to the rotating component 74, and the angle of rotation of the rotating component 74 is almost the same each time. In addition, before sliding to the bottom, the pushing component 73 is partially located outside the fixing box 71 and always abuts against the inner bottom surface of the first sliding groove.

[0054] See also Figure 5-Figure 6The transmission guide box 77 is arranged on the inner wall of the fixed box 71 and is opposite to the pushing guide box 72. The transmission guide box 77 is provided with a second limiting slide groove 771; the transmission component 76 is slidably connected to the inner wall of the fixed box 71 and abuts against the inner bottom surface of the second limiting slide groove 771; the connecting box 78 is arranged on the inner wall of the fixed box 71 and is provided with three slide grooves. The connecting components 79 correspond to the slide grooves and the limiting components 6 one by one. The connecting components 79 are slidably connected in the slide grooves respectively and are connected to the limiting components 6; the ratchet component 75 is arranged on the rotating component 74 and rotates with the rotating component 74. It should be understood that the second limited slot 771 includes two slots with a height difference at the connecting part, and the two slots form a triangle. The first slot is a vertical slot, and the initial position of the transmission component 76 is at the upper end of the vertical slot. The transmission component 76 slides to the other end, that is, the second slot, after being driven three times by the ratchet component 75. Due to the height difference between the two slots, the transmission component 76 cannot return to the initial position by the original path, but can only slide along the second slot and return to the initial position. After returning to the initial position, it is also difficult to return to the second slot due to the height difference. It should also be understood that the transmission component 76 always abuts against the inner bottom surface of the second limited slot 771. At the same time, the transmission component 76 drives the connecting component 79 to slide in turn, and after driving the next connecting component 79 to slide, the previous connecting component 79 can reset itself.

[0055] Repeatedly pushing the pushing assembly 73 can make the ratchet assembly 75 drive the transmission assembly 76 to sequentially squeeze the connecting assembly 79, driving the limiting assembly 6 at the pressing plate 2, the disinfectant 3, and the catheter bag 4 to rotate. Through this mechanism, the pressing plate 2, the disinfectant 3, and the catheter bag 4 can be ejected in sequence, thereby strengthening the operation steps of the operator.

[0056] In other schemes, the pushing assembly 73 includes a pushing block 731, a pushing reset spring 732, a pushing pressure rod 733 and a pushing rack 734; the pushing block 731 is slidably connected to the through hole on the fixed box 71, and is connected to the fixed box 71 through the pushing reset spring 732; the pushing pressure rod 733 is hinged to the pushing block 731 and abuts against the inner bottom surface of the first limiting slide groove 721; the pushing rack 734 is arranged on the pushing pressure rod 733, and the pushing block 731 is pushed, and the pushing rack 734 can mesh with the rotating assembly 74 and drive the rotating assembly 74 to rotate, and then the pushing block 731 is pulled back, and the pushing block 731 can move away from the rotating assembly 74 and return to the initial position. Pushing the pushing block 731 drives the pushing rack 734 to drive the rotating assembly 74 to rotate, and resets from the other side of the first limiting slide groove 721, so that a single push can cause the rotating assembly 74 to rotate a fixed value. When the locking cam 730 is in the closed position, the locking cam 730 is in the closed position, and the spring 732 is in the closed position, so that the locking cam 730 can be locked.

[0057] In other embodiments, the rotating assembly 74 includes a rotating shaft 741 and a pushing gear 742; the rotating shaft 741 is rotatably connected to the inner wall of the fixed box 71, and the pushing gear 742 is coaxially arranged on the rotating shaft 741, and the pushing gear 742 can mesh with the pushing rack 734. Through the cooperation between the pushing gear 742 and the pushing rack 734, the pushing rack 734 can better drive the pushing gear 742 to rotate.

[0058] In other embodiments, the ratchet assembly 75 includes a ratchet body 751, a ratchet pawl 752 and a ratchet spring 753; the ratchet body 751 is coaxially fixed on the rotating shaft 741, the ratchet pawl 752 is hinged to the inner wall of the fixed box 71, and is connected to the inner wall of the fixed box 71 through the ratchet spring 753, and the ratchet pawl 752 can limit the rotation of the ratchet body 751; the ratchet can drive the transmission assembly 76 to slide. By setting the ratchet body 751 and the ratchet pawl 752 of this structure, the ratchet body 751 can maintain the previous state when not rotating, and will not be driven by the transmission assembly 76 to rotate in the opposite direction.

[0059] In other embodiments, the transmission assembly 76 includes a transmission slider 761, a transmission spring 762, a transmission pressure rod 763, a ratchet link block 764 and a transmission block 765; the transmission slider 761 is slidably connected to the inner wall of the fixed box 71 and is connected to the fixed box 71 through the transmission spring 762; the transmission pressure rod 763 abuts against the inner bottom surface of the second limiting slide groove 771, three ratchet link blocks 764 are provided and are arranged on the transmission pressure rod 763, and the transmission block 765 is arranged on the transmission pressure rod 763 near the transmission slider 761 On one side, a single rotation of the ratchet wheel can drive a ratchet link block 764 to slide, and the transmission block 765 can squeeze the connecting assembly 79, so that the connecting assembly 79 slides and drives the limiting assembly 6 to rotate; repeatedly pushing the pushing block 731 can make the ratchet body 751 push the ratchet link block 764 in turn, and make the transmission block 765 squeeze the connecting assembly 79 in turn, and the ratchet body 751 drives the transmission pressure rod 763 to slide three times, and then returns to the initial position along the second limiting slide groove 771 under the action of the transmission spring 762. This structure enables a single rotation of the ratchet body 751 to drive the ratchet link block 764 to slide a certain distance, so that the transmission block 765 can press the connecting assembly 79, so that the connecting assembly 79 can drive the limiting assembly 6 to release the limiting of the pressing plate 2, the disinfectant 3, or the catheter bag 4, and the transmission pressure rod 763 slides through the ratchet link block 764 three times, and then returns to the initial position from the second limiting slide groove 771 again. It should also be understood that after a single rotation of the ratchet body 751, the next ratchet link 764 can be transmitted to the position of the previous ratchet link 764, and the ratchet link 764 abuts against the ratchet link 764. The transmission pressure rod 763 has a certain elasticity, and it always abuts against the inner bottom surface of the second limiting slide groove 771. After the transmission pressure rod 763 is transmitted three times by the ratchet body 751, it slides away from the ratchet body 751 and returns to the initial position. When it slides from the second section to the first section of the second limiting slide groove 771, a gap is left between the transmission pressure rod 763 and the ratchet body 751, and then the ratchet body 751 abuts against the transmission pressure rod 763 under the action of the transmission spring 762.

[0060] See also Figure 5 and Figure 7In other schemes, the connecting component 79 includes a bevel rack 791, a rotating shaft 792, a connecting gear 793, a connecting spring 794 and a connecting rope 795; the bevel rack 791 is slidably connected in the slide groove of the connecting box 78, and is connected to the slide groove of the connecting box 78 through the connecting spring 794; the rotating shaft 792 is rotatably connected in the slide groove of the connecting and, and is coaxially fixed with the connecting gear 793, the connecting gear 793 is meshed with the bevel rack 791, one end of the connecting rope 795 is connected to the rotating shaft 792, and the other end is connected to the limit assembly 6; the transmission block 765 can drive the bevel rack 791 to slide, so that the connecting rope 795 is gradually wrapped around the rotating shaft 792, and drives the limit assembly 6 to rotate. The structure is caused to slide by the bevel rack 791 being squeezed by the transmission block 765, and drives the connecting gear 793 to rotate. The rotation of the connecting gear 793 drives the rotation of the rotating shaft 792, so that the connecting rope 795 is gradually wrapped around the rotating shaft 792, thereby pulling the limiting assembly 6 to rotate, thereby achieving the limitation of the pressing plate 2, disinfectant 3, or catheter bag 4.

[0061] See also Figure 8 and Fig. 9 In other embodiments, the limiting assembly 6 includes a limiting plate 61 and a limiting spring 62; one end of the limiting plate 61 is hinged on the mounting groove 11, and the other end abuts against the pressing plate 2, the disinfectant 3, or the catheter bag 4, and is connected to the mounting groove 11 through the limiting spring 62; the limiting plate 61 is connected to the connecting rope 795, and the connecting rope 795 can drive the limiting plate 61 to rotate and release the limit of the pressing plate 2, the disinfectant 3, or the catheter bag 4. The limiting plate 61 itself is inclined in the mounting groove 11 due to the action of the limiting spring 62, and rotates into the mounting groove 11 after being pulled by the connecting rope 795, and releases the limit of the pressing plate 2, the disinfectant 3, or the catheter bag 4. It should be understood that a through hole is provided in the mounting groove 11, and the connecting rope 795 passes through the through hole to connect with the limiting plate 61.

[0062] By tying the device to the patient, the patient can participate more in the training process during the operation. At the same time, the operating mechanism 7 of the device can make the pressing plate 2 pop out when pressed for the first time, which reminds the operator to press the peritoneal dialysis bag on the pressing plate 2 to check whether the peritoneal dialysis bag is leaking; after pressing and checking, the operating mechanism 7 is pressed for the second time, which pops out the disinfectant 3 to remind the operator to disinfect his hands; after hand disinfection, the operating mechanism 7 is pressed again to make the catheter bag 4 pop out, so that the peritoneal dialysis catheter in the catheter bag 4 can be connected to the dual system of the peritoneal dialysis bag to perform peritoneal dialysis. The operation process before connecting the peritoneal dialysis bag is repeatedly simulated in a fixed order, so that the operator can clearly know each step of the operation, reducing the risk of infection for the patient.

[0063] After completing the above operations, you can connect the dual system of the peritoneal dialysis catheter and the peritoneal dialysis bag, and then perform drainage, venting, filling, reinstalling the iodine cap and other operations.

[0064] The wearable peritoneal dialysis nursing training device can improve the patient's interactivity and strengthen the operator's preliminary operation process.
