Description

Technical Field

[0001] This application relates to the field of medical devices, and more specifically, to a breathing and breath-holding training device. Background Technology

[0002] In chest and abdominal MRI scans, the patient's respiratory cooperation directly affects image quality and examination results. Different examinations have different specific requirements for respiratory amplitude, frequency, and breath-holding. To ensure the patient achieves optimal respiratory cooperation during the examination, breathing training can be conducted beforehand. Two devices have been designed in the existing technology.

[0003] First, for example, Chinese utility model patent application number CN202120097640.4 provides a breathing and breath-holding training device, in which a breathing mask is worn on the patient's face for breath-holding training. This design of the mask pressing on the face can easily cause local pain and redness due to pressure on the face.

[0004] Second, for example, Chinese utility model patent application number CN202220230320.6 discloses a DIBH respiratory movement monitoring device, which mainly includes two mounting pieces that can be respectively attached to the two guardrails of a hospital bed, and adjusting pieces with pressure sensors connected to opposite sides of the two mounting pieces. A monitoring strap that is tied to the patient's chest and abdomen is connected between the two adjusting pieces. When the patient performs breathing exercises, it moves the monitoring strap, and the pressure sensors transmit the sensed values ​​to the processor. The processor then transmits the processed results to the mobile terminal of medical staff or the patient via a wireless transceiver so that medical staff or the patient can view them. This design does not need to be worn on the face, thus avoiding unsightly facial damage. However, the above design requires the use of a hospital bed, which limits the space where the device can be used, and therefore further improvements are needed. Utility Model Content

[0005] To overcome the above shortcomings, this application provides a breathing and breath-holding training device that allows patients to perform breathing and breath-holding training in any desired location, making it highly applicable.

[0006] This application provides a breathing and breath-holding training device, including an adjustable fixing component and a pressure measuring component;

[0007] The adjustable fixing component includes two PVC strips with a semi-circular cross-section that wrap around the waist and abdomen. Both PVC strips have external threads on their outer sides, and an adjusting ring is screwed on them together through the external threads.

[0008] The pressure measuring component includes a housing and elastic members disposed on both sides therein. Pressure sensors are provided on the opposite sides of the two elastic members, and connecting members that slide with the housing are provided on the opposite sides of the two elastic members. The connecting members are connected to the corresponding PVC strips.

[0009] Preferably, the ends of the two PVC strips away from the pressure measuring component are fixed together, and the inner side of the adjusting ring is provided with an internal thread that matches the external thread.

[0010] Preferably, each elastic element includes a spring and pressure plates A and B respectively connected to its two ends. The pressure sensor is installed on the outside of the pressure plate A, and the force-bearing surface of the pressure sensor is movably pressed against the inner wall of the housing.

[0011] Preferably, each of the connecting components includes pull ropes respectively connected to both sides of the pressure plate B. The two side walls of the housing are provided with sliding grooves adapted to the pull ropes. The outer ends of the two pull ropes are connected to a connecting block, and the other end of the PVC strip is fixed to the connecting block.

[0012] Preferably, a rubber pad is also adhered to the side of the shell that fits against the waist and abdomen.

[0013] Preferably, the side of the shell away from the waist and abdomen is designed to be open and has a detachable cover. The corners of the rectangular shell formed by the combination of the cover and the shell are rounded.

[0014] Preferably, a processor and a wireless transceiver are also installed on the outer side of the housing, with the processor output connected to the wireless transceiver and the pressure sensor output connected to the processor.

[0015] Beneficial effects: This application provides a breathing and breath-holding training device. Twisting the adjusting ring allows two PVC strips to fit snugly against the patient's waist and abdomen. During breathing and breath-holding training, the connecting piece pulls the elastic element to shift, thereby pressing the pressure sensor.

Detailed Implementation

[0022] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0023] Please see Figures 1-2 This application provides a breathing and breath-holding training device, including an adjustable fixing component 2 and a pressure measuring component 1;

[0024] The adjustable fixing component 2 includes two PVC strips 21 that are wrapped around the waist and abdomen and have a semi-circular cross section. Both PVC strips 21 have external threads 23 on their outer sides and an adjusting ring 22 is screwed on them together through the external threads 23.

[0025] The pressure measuring component 1 includes a housing 11 and elastic members 13 disposed on both sides therein. Pressure sensors 12 are provided on the opposite sides of the two elastic members 13, and connecting members 14 that slide with the housing 11 are provided on the opposite sides of the two elastic members 13. The connecting members 14 are connected to the corresponding PVC strips 21.

[0026] In this embodiment, the adjusting ring 22 is turned so that the two PVC strips 21 fit against the patient's waist and abdomen. During the patient's breathing and breath-holding training, the connecting piece 14 pulls the elastic piece 13 to move, thereby pressing the pressure sensor 12, causing the pressure sensor 12 to sense the pressure, and then transmitting the sensed value. This application allows patients to perform breathing and breath-holding training in any desired location, making it highly applicable.

[0027] The ends of the two PVC strips 21 away from the pressure measuring component 1 are fixed together, and the inner side of the adjusting ring 22 is provided with an internal thread (not shown) that matches the external thread 23. Specifically, by using the external thread 23 of the two PVC strips 21 combined with the internal thread of the inner wall of the adjusting ring 22, this device can be worn on the waist and abdomen of patients of different body types.

[0028] It should also be noted that PVC strip 21 is a rope made of PVC with a semi-circular cross-section. Two PVC strips 21 can be combined to form a circular design.

[0029] Please see Figures 1-4 Each elastic element 13 includes a spring 131 and pressure plates A132 and B133 connected to its two ends respectively. The pressure sensor 12 is installed on the outside of the pressure plate A132, and the force-bearing surface of the pressure sensor 12 is movably pressed against the inner wall of the housing 11. Specifically, when the patient breathes, the elastic element 13 is pulled in a disjointed direction by the connector 14, causing the pressure sensor 12 to press against the inner wall of the housing 11, thereby allowing the pressure sensor 12 to easily sense changes in breathing in the waist and abdomen.

[0030] Each connector 14 includes a pull rope 141 connected to both sides of the pressure plate B133. The two side walls of the housing 11 are each provided with a groove 111 adapted to the pull rope 141. The outer ends of the two pull ropes 141 are connected to a connecting block 142, and the other end of the PVC strip 21 is fixed to the connecting block 142. Specifically, when the patient breathes, the PVC strip 21 drives the two connecting blocks 142 to move in opposite directions, indirectly causing the pressure plate B133 to compress the spring 131 via the pull ropes 141. The spring 131 then guides the pressure plate A132 to compress the pressure sensor 12 against the inner wall of the housing 11, thus allowing the pressure sensor 12 to easily detect changes in abdominal breathing.

[0031] A rubber pad 16 is also attached to the side of the shell 11 that fits against the waist and abdomen. Specifically, the design of the rubber pad 16 can reduce the pressure discomfort caused to the patient's waist and abdomen when wearing this application.

[0032] The side of the shell 11 away from the waist and abdomen is designed to be open and is detachably fixed with a shell cover 15. The corners of the rectangular shell formed by the shell cover 15 and the shell 11 are rounded. Specifically, the design of the shell cover 15 makes it easy to open the shell 11 to expose the internal structure, which facilitates the maintenance of the internal structure of the shell 11; while the rounded corners further reduce the discomfort when wearing this application.

[0033] Please see Figure 1 A processor and a wireless transceiver are also installed on the outer side of the housing 11. The processor's output is connected to the wireless transceiver, and the pressure sensor 12's output is connected to the processor. The pressure sensor 12 sends pressure values ​​to the processor. The maximum and minimum values ​​received by the processor represent the highest point of the patient's abdomen during inhalation and the lowest point during exhalation. The difference between the maximum inhalation and maximum exhalation abdomen measurements is calculated, representing the abdominal circumference difference. The processor then transmits this abdominal circumference difference to the mobile terminal of the medical staff or patient via the wireless transceiver for monitoring.

[0034] When used in this application:

[0035] Twisting the adjusting ring 22 causes the two PVC strips 21 to fit against the patient's waist and abdomen. During breath-holding training, the PVC strips 21 move the two connecting blocks 142 in opposite directions, indirectly causing the pressure plate B133 to compress the spring 131 via the pull rope 141. The spring 131 then guides the pressure plate A132 to compress the pressure sensor 12 against the inner wall of the housing 11. Thus, the pressure sensor 12 can easily sense changes in breathing in the waist and abdomen. The pressure sensor 12 transmits the sensed values ​​to the processor, which then sends the processed results to the mobile terminal of medical staff or the patient via a wireless transceiver, allowing them to view the data. This application allows patients to perform breath-holding training in any desired location, making it highly applicable.

[0036] It will be apparent to those skilled in the art that this application is not limited to the details of the exemplary embodiments described above, and that this application can be implemented in other specific forms without departing from the spirit or essential characteristics of this application. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this application is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this application. No reference numerals in the claims should be construed as limiting the scope of the claims.
