Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to a safety-type telemetry electrocardiogram monitoring box wearing fixator. Background Art

[0002] In the modern medical system, electrocardiogram monitoring is a key means for real-time monitoring of a patient's cardiac function, and plays a crucial role in promptly detecting cardiac abnormalities and ensuring the patient's life and health. As a convenient wearable electrocardiogram monitoring device, a telemetry electrocardiogram monitoring box can enable a patient to collect and transmit electrocardiogram data for a long time in a relatively free movement state, greatly improving the flexibility of medical monitoring and the comfort of the patient.

[0003] In the prior art, a Chinese patent with the authorization announcement number CN222032413U discloses a wearable remote electrocardiogram monitoring device. In the published document, by installing a pressure sensing device, the occurrence of abnormal electrocardiogram monitoring caused by abnormal wearing of the device by the patient is avoided, so that the device can be more stable when performing electrocardiogram monitoring on the patient. By installing an adjustable clamping device, the adjustable clamping device is used to adjust the size of the device, so that the device has better compatibility. However, during the actual wearing process of the patient, the pressures at different positions of the strap are different, which easily leads to inaccurate detection results of the pressure sensing device, thereby affecting the comfort of the patient wearing the electrocardiogram monitoring box. When the comfort of the patient wearing the electrocardiogram monitoring box decreases, the patient is prone to psychological pressure, which in turn affects the detection accuracy of the electrocardiogram monitoring box. Summary of the Invention

[0004] The present invention provides a safety-type telemetry electrocardiogram monitoring box wearing fixator to solve the problem that the existing electrocardiogram monitoring box affects the comfort of the patient during wearing.

[0005] The following technical solutions are adopted for the safety-type telemetry electrocardiogram monitoring box wearing fixator of the present invention: A safety-type telemetry electrocardiogram monitoring box wearing fixator includes a strap, two adjusting rollers, two elastic bands, and a locking member.

[0006] An installation frame is arranged in the middle of the strap, and the installation frame is used for installing an electrocardiogram monitoring box; each end of the strap is rotatably connected with a connection frame, and a first sliding groove is arranged on each connection frame; each adjusting roller is rotatably arranged in a first sliding groove, and each adjusting roller can slide in a first sliding groove; each elastic band is wound around an adjusting roller, each elastic band moves synchronously with an adjusting roller, the ends of the two elastic bands close to each other are connected through a connecting member, and the other end of the elastic band is connected to the middle of the elastic band through a magic tape; the locking member is used to prevent the adjusting roller from rotating and sliding in the first sliding groove when the patient is comfortable.

[0007] Further, the locking member includes a locking gear and fixed teeth. The locking gear is coaxially and fixedly arranged on the adjusting roller, and the fixed teeth are fixedly arranged at the end of the first chute. When the adjusting roller slides to the end of the first chute, the fixed teeth engage with the locking gear.

[0008] Further, an adjusting member is arranged on the connecting frame. The adjusting member can adjust the ease of sliding of the adjusting roller in the first chute, and the adjusting roller is initially located in the middle of the first chute.

[0009] Further, the adjusting member includes a stop block and a pressing block. The stop block is slidably connected to the connecting frame, and the sliding direction of the stop block on the connecting frame is perpendicular to the extending direction of the first chute. One end of the stop block can extend into the first chute. When one end of the stop block is in the first chute, the stop block can prevent the adjusting roller from approaching the end of the first chute; the pressing block is slidably connected to the connecting frame, and the sliding direction of the pressing block on the connecting frame is parallel to the extending direction of the first chute. The pressing block abuts against the stop block, and the pressing block can prevent the stop block from sliding on the connecting frame.

[0010] Further, the adjusting member further includes an adjusting spring. The adjusting spring is arranged along the extending direction of the first chute, and the adjusting spring is arranged between the pressing block and the connecting frame. The compression amount of the adjusting spring can change the pressing force of the pressing block on the stop block.

[0011] Further, the adjusting member further includes an adjusting block and a second chute. The second chute is arranged on the connecting frame, and the second chute is arranged in parallel with the first chute. The adjusting block is slidably arranged along the second chute, and the pressing block is slidably arranged in the second chute; the adjusting block can stay at any position of the second chute, and the adjusting spring is fixedly arranged between the adjusting block and the pressing block.

[0012] Further, an auxiliary roller is arranged in the first chute. The auxiliary roller is arranged in parallel and at intervals with the adjusting roller. A first gear is coaxially and fixedly arranged on the auxiliary roller, and a second gear is coaxially and fixedly arranged on the adjusting roller. The first gear and the second gear are always meshed, and the elastic belt passes between the adjusting roller and the auxiliary roller.

[0013] Further, the distance between the auxiliary roller and the adjusting roller is slightly smaller than the thickness of the elastic belt.

[0014] Further, a fixing frame is rotatably connected between the auxiliary roller and the adjusting roller, and the fixing frame is slidably arranged along the first chute.

[0015] Further, a plurality of friction protrusions are provided on the outer side wall of the adjusting roller.

[0016] The beneficial effects of the present invention are as follows: A safety-type telemetry electrocardiogram monitoring box wearing fixator of the present invention includes a strap, two adjusting rollers, two elastic bands and a locking member. When the heart function of a patient is monitored in real time, a mounting frame is provided in the middle of the strap, and the electrocardiogram monitoring box is mounted on the mounting frame. Two connecting frames are provided at both ends of the strap. The strap can be bent arbitrarily. An adjusting roller is provided on each connecting frame, and each elastic band is wound around an adjusting roller. The ends of the two elastic bands close to each other are connected by a connecting member. When the elastic band is wound around the adjusting roller, the elastic band and the adjusting roller move synchronously. When the other end of the elastic band is pulled by an external force, the elastic band can undergo elastic deformation, and the adjusting roller rotates. When the patient is in a comfortable state, the locking member hinders the rotation and sliding of the adjusting roller in the first chute, releases the external force traction on the ends of the two elastic bands, and then connects the pulled end of the elastic band to the middle of the elastic band through a magic tape, so as to ensure that the patient is in a comfortable state when wearing and reduce the psychological pressure of the patient.

[0017] Further, when the same patient needs to be disassembled, it only needs to disassemble the connection position of the two elastic bands at the position of the connecting member. When wearing next time, there is no need for the adjusting roller to rotate, so as to quickly reach a comfortable state for the patient to wear. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] As Figures 1 to 8 shown, a wearable fixator for a safe telemetry electrocardiogram monitoring box provided by an embodiment of the present invention includes a strap 110, two adjusting rollers 160, two elastic bands 170 and a locking member.

[0025] The strap 110 is in a long strip shape and can be deformed arbitrarily to ensure that the strap 110 can fit the patient's skin. An installation frame 120 is provided in the middle of the strap 110 in the length direction. The installation frame 120 is used to install an electrocardiogram monitoring box 130, and the electrocardiogram monitoring box 130 can collect the electrocardiogram data of the patient. A connection frame 150 is rotatably connected to each end of the strap 110. Specifically, a first connection buckle 140 is sewn at each end of the strap 110. The outline of the connection frame 150 is slightly rectangular, and the connection frame 150 is rotatably connected at the first connection buckle 140. A first chute 151 is provided on the connection frame 150. When the connection frame 150 and the strap 110 are coplanar, the first chute 151 is arranged along the length direction of the strap 110.

[0026] There are two adjusting rollers 160, and each adjusting roller 160 is arranged on a connection frame 150. The length of the adjusting roller 160 in the axial direction is greater than the width of the strap 110. Each adjusting roller 160 is slidably arranged in a first chute 151, and the adjusting roller 160 can rotate in the first chute 151. In the initial state, the adjusting roller 160 is located in the middle of the first chute 151.

[0027] There are two elastic bands 170. The elastic bands 170 can undergo elastic deformation. The width of the elastic bands 170 is equal to the width of the binding straps 110. The ends of the two elastic bands 170 that are close to each other can be connected through a connecting member. Specifically, the connecting member is a connecting frame 180. The outer shape of the connecting frame 180 is slightly in the shape of an 'e'. Then the connecting frame 180 has three connecting rods that are parallel to each other and fixedly connected. Two adjacent connecting rods enclose a closed loop. A second connecting buckle 171 is sewn at the end of the elastic band 170. When sewing the second connecting buckle 171 on one of the elastic bands 170, the end of the elastic band 170 is passed through the closed loop formed by two adjacent connecting rods. When connecting the two elastic bands 170, only need to insert another connecting rod into one of the second connecting buckles 171.

[0028] Furthermore, each elastic band 170 is arranged around an adjusting roller 160, and each elastic band 170 moves synchronously with an adjusting roller 160. Specifically, during the wearing process, each elastic band 170 is arranged around an adjusting roller 160, and then the ends of the two elastic bands 170 are manually pulled close to each other, so that the two elastic bands 170 are deformed. During the deformation process of the elastic bands 170, the adjusting roller 160 rotates synchronously. When the comfort level of the patient during wearing reaches the best, the locking member hinders the rotation and sliding of the adjusting roller 160 in the first sliding groove 151. At this time, release the pulling of the ends of the elastic bands 170, and the elastic bands 170 will not move relative to the adjusting roller 160. At this time, the ends of the two elastic bands 170 are not pulled by an external force. By setting Velcro on the ends and the middle parts of the elastic bands 170, the ends and the middle parts of the elastic bands 170 are connected through Velcro. When the same patient needs to disassemble, only need to disassemble the connecting rod from the second connecting buckle 171. When wearing next time, there is no need for the adjusting roller 160 to rotate, so as to quickly reach the comfortable state of the patient wearing.

[0029] A safety-type telemetry electrocardiogram monitoring box wearing fixator of the present invention includes a strap 110, two adjusting rollers 160, two elastic bands 170 and a locking member. When the heart function of a patient is monitored in real time, a mounting frame 120 is provided in the middle of the strap 110, and an electrocardiogram monitoring box 130 is mounted on the mounting frame 120. Two connecting frames 150 are provided at both ends of the strap 110. The strap 110 can be bent arbitrarily. An adjusting roller 160 is provided on each connecting frame 150, and each elastic band 170 is wound around an adjusting roller 160. The ends of the two elastic bands 170 close to each other are connected by a connecting member. When the elastic band 170 is wound around the adjusting roller 160, the elastic band 170 moves synchronously with the adjusting roller 160. When the other end of the elastic band 170 is pulled by an external force, the elastic band 170 can undergo elastic deformation, and the adjusting roller 160 rotates. When the patient is in a comfortable state, the locking member hinders the rotation and sliding of the adjusting roller 160 in the first chute 151, releases the external force traction on the ends of the two elastic bands 170, and then connects the pulled end of the elastic band 170 to the middle of the elastic band 170 through Velcro, so as to ensure that the patient is in a comfortable state during wearing and reduce the psychological pressure of the patient.

[0030] In one embodiment, the locking member includes a locking gear 210 and a fixed tooth 220. The locking gear 210 is coaxially and fixedly arranged outside the adjusting roller 160, and the fixed tooth 220 is fixedly arranged at the end of the first chute 151. Specifically, in the first chutes 151 of the two connecting frames 150, the fixed tooth 220 is arranged at the ends of the two first chutes 151 close to each other. During the wearing process of the patient, the two adjusting rollers 160 gradually approach each other along the first chute 151 during rotation. When the patient is in a comfortable state, the adjusting roller 160 slides to the end of the first chute 151. At this time, the locking gear 210 meshes with the fixed tooth 220, thereby restricting the rotation of the adjusting roller 160 in the first chute 151. The length of the first chute 151 restricts the sliding of the adjusting roller 160, so as to ensure that the adjusting roller 160 is in a stable state.

[0031] In one embodiment, an adjusting member is provided on the connecting frame 150. The adjusting member can adjust the difficulty of the adjusting roller 160 sliding in the first chute 151. When different patients wear it, the stretching degree of the elastic band 170 and the feelings of different patients are different. The adjusting member can ensure that different patients can reach a comfortable state when different patients wear it.

[0032] In one embodiment, the adjusting member includes a stop block 230 and a pressing block 240. The stop block 230 is slidably connected to the connecting frame 150. Specifically, a limiting groove is provided on the connecting frame 150. The limiting groove is perpendicular to the first sliding groove 151 and communicates with the first sliding groove 151. The stop block 230 is slidably disposed in the limiting groove. One end of the stop block 230 can extend into the first sliding groove 151, and the other end of the stop block 230 is always within the limiting groove. Since the adjusting roller 160 is initially located in the middle of the first sliding groove 151, during the wearing process, the adjusting roller 160 gradually slides towards the end of the first sliding groove 151. During this process, the adjusting roller 160 can contact the stop block 230. Further, initially, one end of the stop block 230 is located in the first sliding groove 151, and the stop block 230 can hinder the sliding of the adjusting roller 160 along the first sliding groove 151. When the adjusting roller 160 slides along the first sliding groove 151, the adjusting roller 160 can completely squeeze the stop block 230 into the limiting groove.

[0033] Further, the pressing block 240 is slidably connected to the connecting frame 150. A second sliding groove 152 is provided on the connecting frame 150. The second sliding groove 152 is arranged in parallel and spaced from the first sliding groove 151. One end of the second sliding groove 152 communicates with the limiting groove. The pressing block 240 is slidably disposed along the second sliding groove 152. Initially, one end of the pressing block 240 is disposed in the limiting groove, and the pressing block 240 can abut against the stop block 230, so as to realize the pressing of the pressing block 240 on the stop block 230. The greater the pressing force of the pressing block 240 on the stop block 230, the greater the difficulty for the stop block 230 to completely enter the limiting groove.

[0034] In one embodiment, the adjusting member further includes an adjusting spring 250. The adjusting spring 250 is disposed in the second sliding groove 152, and the elasticity of the adjusting spring 250 is adjustable. One end of the adjusting spring 250 is connected to the pressing block 240, and the other end of the adjusting spring 250 is disposed at the end of the second sliding groove 152. When the elastic force of the adjusting spring 250 increases, the pressing force of the pressing block 240 on the stop block 230 increases simultaneously, so the difficulty for the stop block 230 to completely enter the limiting groove increases, and the difficulty for the adjusting roller 160 to slide along the first sliding groove 151 increases.

[0035] In one embodiment, the adjusting member further includes an adjusting block 260 which is slidably disposed along the second chute 152. The adjusting block 260 can stay at any position of the second chute 152. Specifically, a positioning screw is provided on the adjusting block 260. The positioning screw penetrates through the adjusting block 260 and is perpendicular to the extending direction of the second chute 152. The side wall of the positioning screw is threadedly connected to the adjusting block 260. After the adjusting block 260 moves along the second chute 152, by rotating the positioning screw, the positioning screw is in close contact with the second chute 152, so as to realize that the adjusting block 260 stays at any position of the second chute 152. Further, an adjusting spring 250 is fixedly disposed between the adjusting block 260 and the pressing block 240. When it is necessary to adjust the elastic force of the adjusting spring 250, the position of the adjusting block 260 in the second chute 152 can be adjusted.

[0036] In one embodiment, an auxiliary roller 270 is disposed in the first chute 151. The auxiliary roller 270 is arranged in parallel and at an interval with the adjusting roller 160. A first gear 280 is coaxially and fixedly disposed on the auxiliary roller 270, and a second gear 290 is coaxially and fixedly disposed on the adjusting roller 160. The first gear 280 and the second gear 290 are always meshed. By providing the first gear 280 and the second gear 290, the adjusting roller 160 and the auxiliary roller 270 rotate synchronously, and the elastic belt 170 passes between the adjusting roller 160 and the auxiliary roller 270. Further, by setting the diameters of the first gear 280 and the second gear 290, it is ensured that the distance between the auxiliary roller 270 and the adjusting roller 160 is slightly smaller than the thickness of the elastic belt 170. When the elastic belt 170 passes between the adjusting roller 160 and the auxiliary roller 270, the elastic belt 170 can be squeezed by the auxiliary roller 270 and the adjusting roller 160, so as to realize the close contact between the elastic belt 170 and the adjusting roller 160.

[0037] In one embodiment, a plurality of friction protrusions are provided on the outer side wall of the adjusting roller 160. When the elastic belt 170 is squeezed by the auxiliary roller 270 and the adjusting roller 160, the plurality of friction protrusions are in close contact with the elastic belt 170, so as to prevent relative movement between the elastic belt 170 and the adjusting roller 160.

[0038] In one embodiment, to ensure a stable gap between the auxiliary roller 270 and the adjusting roller 160, a fixing frame 190 is connected between the auxiliary roller 270 and the adjusting roller 160. The auxiliary roller 270 is rotatably connected to the fixing frame 190, and the adjusting roller 160 is rotatably connected to the fixing frame 190. The fixing frame 190 can slide along the first chute 151. By providing the fixing frame 190, it is ensured that the gap between the auxiliary roller 270 and the adjusting roller 160 remains in a stable state, and further ensured that the first gear 280 and the second gear 290 remain in a meshed state all the time.

[0039] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
