Description

Technical Field

[0001] This application belongs to the field of medical device technology, and in particular relates to a home positioning guide device for stone removal. Background Technology

[0002] A postural stone-expelling bed is a medical device that assists in the expulsion of urinary system stones. It is designed based on the anatomical structure of the human urinary system and the principle of natural stone expulsion within the urinary system. When the body is in different positions, the position and angle of organs in the urinary system, such as the renal pelvis and ureter, change. Utilizing gravity, this promotes the movement of stones within the urinary system, thereby increasing the chances of stone expulsion. For example, when a patient is in a prone position, stones in the upper renal calyces may move towards the renal pelvis and ureter due to gravity.

[0003] However, current lithotripsy beds are complex in structure and large in size, making them expensive for patients and inconvenient for home use. Patients usually need to go to a specialized ward in a hospital to use them for lithotripsy. Furthermore, multiple trips to the hospital increase the patient's time and expenses.

[0004] Therefore, the aforementioned technical deficiencies urgently need to be addressed. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a home-based positioning stone removal guidance device, which aims to reduce the cost of patients using positioning drainage beds, reduce the number of times patients need to return to the hospital, and improve the efficiency of patients' positioning stone removal.

[0006] The technical solution adopted by this application to solve the technical problem is as follows: a home-based posture guidance device for stone removal, comprising:

[0007] The fixation base is used to secure the patient's waist.

[0008] And a kidney model, which is set on a fixed base and has ureters. The kidney model is made of transparent material.

[0009] The kidney model includes a renal pelvis, a major calyx, and a minor calyx. The ureter, renal pelvis, major calyx, and minor calyx are connected sequentially. The ureter, renal pelvis, major calyx, and minor calyx are used to simulate the ureter, renal pelvis, major calyx, and minor calyx of a human kidney, respectively.

[0010] In this embodiment, the ureter, renal pelvis, major calyx, and minor calyx are connected to form a cavity structure, and at least one stone-like object is placed inside the cavity structure.

[0011] In this embodiment, an observation area is provided on the cavity structure, which is used to display the interior of the cavity structure.

[0012] In this embodiment, the observation area is further configured to cover the entire surface of the cavity structure.

[0013] In this embodiment, a prompting component is further provided on the kidney model, the prompting component including:

[0014] The indicator device is installed on the kidney model and is used to indicate when a stone-like object has entered the ureter.

[0015] And a trigger, which is located on the end of the ureter away from the renal pelvis, and is used to trigger the prompting device.

[0016] In this embodiment, the prompting device is further configured to include at least a speaker for prompting the patient, and a trigger is electrically connected to the prompting device.

[0017] In this embodiment, a fixing belt is detachably connected to the fixing base. The fixing belt is an elastic belt with adjustable length and is used to fix the fixing base to the patient's waist.

[0018] In this embodiment, the fixed belt is further configured to have position marks.

[0019] In this embodiment, the fixed base is further configured as an elastic base, and a buffer layer is provided on the end of the fixed base that is away from the kidney model.

[0020] Compared with existing technologies, this application provides a home-based positioning guidance device for kidney stone removal. The transparent kidney model of this invention allows patients to visually observe the movement trajectory of the stone-like structures inside the kidney model in different positions. During use, the patient can wear the kidney model at a preset position on their waist and change position according to the dynamic movement of the stone-like structures within the model until the structures are expelled from the renal pelvis. This reduces the cost of using a positioning drainage bed, decreases the number of hospital visits, and improves the efficiency of postural stone removal. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0030] Furthermore, the technical features involved in the different embodiments of the present invention described above can be combined with each other as long as they do not conflict with each other.

[0031] This utility model provides, for example Figure 1 , Figure 3 The device, as shown, is a home-based posture-based stone-expelling guidance device designed based on the anatomical structure of the human urinary system and the principle of natural stone expulsion within the urinary system. It assists patients in expelling urinary system stones. The main structure of this invention includes a fixing base 1 and a kidney model 2. The kidney model 2 is manufactured in a 1:1 scale based on the structural characteristics of a human kidney and can be produced using 3D printing. The fixing base 1 is used to fix the device to the patient's waist, ensuring a fixed relative position between the kidney model 2 and the fixing base 1. When worn by the patient, the kidney model 2 can move and adjust with changes in the patient's posture. Kidney model 2 is mounted on a fixed base 1. A ureter 21 is mounted on kidney model 2. Kidney model 2 is made of transparent material, allowing patients to visually observe the internal structure and understand the movement path of the kidney stone under gravity. Kidney model 2 contains a renal pelvis 22, a major calyx 23, and a minor calyx 24. The ureter 21, renal pelvis 22, major calyx 23, and minor calyx 24 are sequentially connected, simulating the ureter 21, renal pelvis, major calyx, and minor calyx of a human kidney, respectively. The arrangement of the ureter 21, renal pelvis 22, major calyx 23, and minor calyx 24 on kidney model 2 is based on the structural characteristics of a human kidney.

[0032] It should be noted that current lithotripsy beds are complex in structure and large in size, resulting in high purchase costs for patients and making them inconvenient for home use. Patients typically need to go to a specialized ward in a hospital to use them for lithotripsy. Furthermore, multiple trips to the hospital increase the patient's time and expenses.

[0033] This invention, a transparent kidney model 2, allows patients to visually observe the movement trajectory of the stone-like components 26 inside the kidney model 2 under different body positions. During use, the patient wears the kidney model 2 at a preset position on their waist and changes position according to the dynamic movement of the stone-like components 26 until they are expelled from the renal pelvis. For example, when the patient is in a prone position, they can see the stone-like components 26 moving towards the renal pelvis under the influence of gravity. At this time, any stones that may be present in the upper renal calyx will move towards the renal pelvis and ureter 21 due to gravity. This reduces the cost of using a postural drainage bed, decreases the number of hospital visits, and improves the efficiency of postural stone expulsion.

[0034] As is well known, the human body has two kidneys, left and right. The kidney model 2 in this design also comes in two types: left and right kidney models 2. In some embodiments, at least one kidney model 2, either a left kidney model 2 or a right kidney model 2, or both left and right kidney models 2, are mounted on the fixed base 1. Furthermore, the left and right kidney models 2 are positioned and angled to correspond to the left and right kidneys of the human body.

[0035] Furthermore, such as Figure 3 , Figure 4 As shown, the ureter 21, renal pelvis 22, major calyx 23 and minor calyx 24 are connected to form a hollow structure 25, and the hollow structure 25 contains at least one stone-like component 26.

[0036] Furthermore, an observation area is provided on the hollow structure 25 to display the interior of the hollow structure 25. Patients can observe the interior of the hollow structure 25 (ureter 21, renal pelvis 22, major calyx 23 and minor calyx 24) through the observation area, including the movement of the stone-like component 26 inside the hollow structure 25.

[0037] Furthermore, the observation area covers the entire surface of the hollow structure 25. That is, the ureter 21, renal pelvis 22, major calyx 23, and minor calyx 24 are all visible structures.

[0038] Specifically, during the manufacturing process, transparent materials can be used to fabricate the structures of the ureter 21, renal pelvis 22, major calyx 23, and minor calyx 24. In order to distinguish the different structures of the ureter 21, renal pelvis 22, major calyx 23, and minor calyx 24, different colored visible materials can be used to fabricate different structural parts.

[0039] Furthermore, such as Figure 4 As shown, a prompting component 3 is provided on the kidney model 2. The prompting component 3 includes a prompting device 31 and a trigger 32. The prompting device 31 is provided on the kidney model 2 and is used to prompt that the stone-like object 26 has entered the ureter 21. The trigger 32 is provided on the end of the ureter 21 away from the renal pelvis 22 and is used to trigger the prompting device 31.

[0040] Understandably, patients may have difficulty observing the inside of the kidney model 2 while performing certain postures. Therefore, a prompting component 3 installed on the kidney model 2 can alert the patient whether the stone-like object 26 has entered the ureter 21. When the stone-like object 26 enters the ureter 21, it will touch or impact the trigger 32, which is electrically connected to the prompting device 31. Therefore, the prompting device 31 will issue a prompt to alert the patient. The prompting device 31 can emit an audible, vibration, or light alert.

[0041] Furthermore, such as Figure 4 As shown, the prompting device 31 includes at least a speaker 311 for prompting the patient, and a trigger 32 is electrically connected to the prompting device 31. The prompting device 31 emits an audible prompt through the speaker 311 to remind the patient that the stone-like object 26 has entered the ureter 21.

[0042] Furthermore, such as Figure 2 As shown, a fixing belt 11 is detachably connected to the fixing base 1. The fixing belt 11 is an elastic belt with adjustable length and is used to fix the fixing base 1 to the patient's waist.

[0043] Understandably, the patient uses a waist belt 11 to fix the kidney model 2 in a predetermined position on the waist.

[0044] Furthermore, the fixing belt 11 is equipped with position markers. These markers help the patient identify the location where the kidney model 2 needs to be fixed, ensuring that the angular orientation of the kidney model 2 and the patient's kidney are approximately the same, thus guaranteeing the effectiveness of the guiding device.

[0045] Furthermore, such as Figure 1 and Figure 2 As shown, the fixing base 1 is an elastic base, and a buffer layer 12 is provided on the end of the fixing base 1 that is away from the kidney model 2. It can be understood that the buffer layer 12 is used to fit against the patient's abdomen to avoid local pressure marks on the patient's abdomen caused by prolonged compression.

[0046] In summary, this application provides a home-based positioning guidance device for kidney stone removal. The transparent kidney model 2 of this invention allows patients to visually observe the movement trajectory of the stone-like components 26 inside the kidney model 2 under different positions. During use, the patient can wear the kidney model 2 at a preset position on their waist and change position according to the dynamic movement of the stone-like components 26 within the kidney model 2 until the stone-like components 26 are expelled from the renal pelvis. This reduces the cost of using a positioning drainage bed, decreases the number of hospital visits, and improves the efficiency of positioning for stone removal.

[0047] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
