Description

Technical Field

[0001] The present invention belongs to the field of medical auxiliary devices, specifically an automatic lifting handrest system for transradial artery intervention. Background Art

[0002] The application of transradial artery intervention in coronary intervention therapy has been very extensive and has become the preferred method in many centers. In transradial artery intervention surgery, using a simple forearm to right radial artery flat support is a common operation method. This support device is usually used to fix the patient's forearm to ensure the stability and comfort of the arm during the operation.

[0003] A patent document with the publication number CN205006994U discloses a transradial artery puncture handrest bracket, which includes a fixed flat plate. The end of the fixed flat plate is provided with a handrest member that can rotate in a horizontal plane relative to the fixed flat plate, and the end of the handrest member can rotate in a vertical plane relative to the end where the handrest member is connected to the fixed flat plate. The present utility model sets a fixed flat plate and uses the patient's own gravity to fix the device of the present utility model.

[0004] In the traditional technical solution, a simple forearm to right radial artery flat support is used to place and fix the patient's forearm. Although it can be used, there are still many inconveniences in actual operation. The traditional support device is an L-shaped flat plate. When in use, a part of the flat plate needs to be padded under the patient's back. In this case, it is easy to change the patient's body posture, resulting in the patient's uncomfortable posture and inconsistent arm length and placement posture. Moreover, during the transradial artery intervention surgery, affected by various factors, one of the patient's left and right hands is selected for the intervention process. The traditional support device is not convenient enough to use in this situation.

[0017] The beneficial effects of the present invention are as follows: 1. For the transradial artery intervention automatic lifting handrest system of the present invention, it can be assembled with the DSA platform through the mobile lifting handrest device, and can be flexibly used to place the left and right arms of different patients. The elastic setting of the ergonomic wrist pad conforms to ergonomics, and thus adapts to the patient's wrist, providing wrist support, avoiding the influence of the uncomfortable arm on the surgical effect. Inside the support bar, there is also a structure for sucking gas, which can suck the gas inside the ergonomic wrist pad through a plurality of uniformly distributed through holes, reducing the heat generated by the wrapping of the patient's wrist and further improving the comfort of the patient's arm placement.

[0018] 2. For the transradial artery intervention automatic lifting handrest system of the present invention, when the mobile stretcher is moved and adjusted on the medical bed to adapt to different patients, at this time, with the cooperation of the telescopic rod, the lifting handrest device moves along with the mobile stretcher, so that the patient's arm can always be on the lifting handrest device. When the automatic lifting table drives the mobile stretcher to lift or lower electrically, the horizontal plane of the fixed bar remains fixed, so that the bottom plate remains fixed. With the cooperation of a plurality of telescopic columns, the lifting or lowering of the mobile stretcher drives the lifting or lowering of the rotating handrest assembly, still making the patient's arm always on the rotating handrest assembly. After the lifting handrest device is assembled with the DSA platform, it can be automatically lifted or lowered to adapt to patients' surgeries in different situations.

[0019] 3. The automatic lifting handrest system for transradial artery intervention according to the present invention generates suction force in the L-shaped trachea by starting the fixed air pump. For example, when the L-shaped handrest plate 1 is above the L-shaped trachea, the L-shaped trachea generates suction force to work on the inside of the ergonomic wrist pad and multiple through holes provided inside the ergonomic wrist pad below the ergonomic wrist pad. That is, the multiple pore structures inside the ergonomic wrist pad generate a suction air direction, quickly dissipating heat from the patient's wrist, avoiding affecting the subsequent surgical process due to sweating. The suctioned gas is introduced into the air groove in the fixed column through the L-shaped trachea and the air guide pipe, and then the gas is introduced into the outside through the air groove and the air holes. The suctioned wind force will not act on the patient or the doctor, avoiding affecting the surgical process. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE INVENTION

[0023] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0024] Embodiment 1: As Figures 1-5 shown, the transradial artery intervention automatic lifting handrest system of the embodiment of the present invention includes a lifting handrest device 2. One side of the lifting handrest device 2 is provided with a DSA platform 1. The DSA platform 1 includes an automatic lifting table 11 and a medical bed 12 fixedly installed above the automatic lifting table 11. A movable lying board 13 is slidably installed above the medical bed 12. A medical component 14 is installed on the side of the medical bed 12. The lifting handrest device 2 includes a lifting frame 4 and a rotating handrest component 3 movably installed inside the lifting frame 4. The rotating handrest component 3 includes a support bar 32 rotatably installed inside the upper part of the lifting frame 4. The upper and lower sides of the support bar 32 are fixedly installed with an L-shaped handrest plate one 31 and an L-shaped handrest plate two 33. The L-shaped handrest plate one 31 and the L-shaped handrest plate two 33 are components made of the same structure; An ergonomic wrist pad 311 and a restraint strap 312 are fixedly installed above the L-shaped handrest plate one 31. Through holes are evenly distributed inside the ergonomic wrist pad 311, and a plurality of through holes penetrate the L-shaped handrest plate one 31. A structure for sucking gas is provided inside the support bar 32.

[0025] Specifically, when a patient needs to undergo a radial artery intervention, first let the patient lie on the mobile stretcher board 13, and then determine the arm of the patient that needs to undergo the operation. When the operation needs to be performed on the patient's left arm, push the lifting handrest device 2 to make it close to the left side of the DSA platform 1 and be detachably fixed to the DSA platform 1, that is, the first L-shaped handrest board 31 is connected to the mobile stretcher board 13. At this time, the lifting handrest device 2 and the DSA platform 1 form an integral body. The patient's left hand is placed on the first L-shaped handrest board 31 with an L-shaped panel, and the patient's wrist is placed on the ergonomic wrist pad 311 and fixed by the restraint strap 312. Subsequently, the operation is carried out in cooperation with the medical component 14. When the operation needs to be performed on the right arm of different patients, disassemble to separate the DSA platform 1 and the lifting handrest device 2, push the lifting handrest device 2 to move it close to the right side of the DSA platform 1, and drive the first L-shaped handrest board 31 and the second L-shaped handrest board 33 to rotate through the rotational setting of the support bar 32 inside the U-shaped frame 41, so that the second L-shaped handrest board 33 faces upward. Continue to push the lifting handrest device 2 to make the second L-shaped handrest board 33 be detachably installed on the other side of the mobile stretcher board 13, and then form an integral body. The patient's right hand is placed on the second L-shaped handrest board 33 with an L-shaped panel, and the patient's wrist is placed on the ergonomic wrist pad 311 and fixed by the restraint strap 312. Subsequently, the operation is carried out in cooperation with the medical component 14. The mobile lifting handrest device 2 is assembled with the DSA platform 1, which can be flexibly used to place the left and right arms of different patients. The elastic setting of the ergonomic wrist pad 311 conforms to ergonomics, thereby adapting to the patient's wrist, providing wrist support, and avoiding the influence of the discomfort of the arm on the surgical effect. A gas suction structure is also provided inside the support bar 32, and the gas inside the ergonomic wrist pad 311 can be suctioned through a plurality of uniformly distributed through holes, reducing the heat generated by the wrapping of the patient's wrist and further improving the comfort of the patient's arm placement.

[0026] As Figures 2-4 shown, a surgical computer 18 is fixedly installed at the end of the medical bed 12, a plurality of first fixed cylinders 131 are fixedly installed on both sides of the mobile stretcher board 13, two L-shaped brackets 15 are fixedly installed on the bottom side of the automatic lifting platform 11, a telescopic rod 16 is fixedly installed on one side of the L-shaped bracket 15, a fixed strip 17 is fixedly installed at the end of the telescopic rod 16, and a plurality of second fixed cylinders 171 are fixedly installed on the side of the fixed strip 17.

[0027] A plurality of fitting columns 34 are fixedly installed on both sides of the first L-shaped handrest board 31 and the second L-shaped handrest board 33, and the plurality of fitting columns 34 are matched with the corresponding plurality of first fixed cylinders 131. The lifting frame 4 includes a bottom plate 42, and a plurality of fitting columns 34 are fixedly installed on the side of the bottom plate 42 facing the telescopic rod 16. The lifting handrest device 2 is installed by matching the plurality of fitting columns 34 with the corresponding first fixed cylinders 131 and second fixed cylinders 171.

[0028] The lifting frame 4 also includes a plurality of universal wheels 43 fixedly mounted below the bottom plate 42 , a plurality of telescopic columns 44 fixedly mounted above the bottom plate 42 , a U-shaped frame 41 fixedly mounted above the plurality of telescopic columns 44 , and the rotating hand support assembly 3 movably mounted inside the U-shaped frame 41 .

[0029] Specifically, when the DSA platform 1 and the lifting hand support device 2 need to be detachably assembled, the L-shaped hand support plate 31 is set upward, and the lifting hand support device 2 is pushed close to the left side of the DSA platform 1, so that the interlocking column 34 on the side of the L-shaped hand support plate 31 is aligned with the corresponding fixed cylinder 131 on one side of the DSA platform 1, until the interlocking column 34 on the side of the L-shaped hand support plate 31 is inserted into the corresponding fixed cylinder 131. At this time, the interlocking column 34 on the outer side of the bottom plate 42 is inserted into the corresponding fixed cylinder 2 171, and the assembly of the DSA platform 1 and the lifting hand support device 2 is completed. When the movable lying plate 13 is moved and adjusted on the medical bed 12 to adapt to different patients, the telescopic rod 16 is extended and retracted. With the cooperation of , the lifting hand support device 2 moves along with the movable lying board 13, so that the patient's arm can always be on the lifting hand support device 2. When the automatic lifting platform 11 is electrically driven to drive the movable lying board 13 to rise and fall, the horizontal plane of the fixed bar 17 is fixed to keep the bottom plate 42 fixed. With the cooperation of multiple telescopic columns 44, the lifting and lowering of the movable lying board 13 drives the lifting and lowering of the rotating hand support assembly 3, so that the patient's arm is still always on the rotating hand support assembly 3. After being assembled with the DSA platform 1, the lifting hand support device 2 can be automatically lifted and lowered to adapt to patient surgeries in different situations, and there is no need to set an electric drive structure inside the lifting hand support device 2 to provide lifting capability, thereby saving energy.

[0030] like Figures 4-5 As shown, a semi-arc groove 411 and an air hole 412 are formed inside the U-shaped frame 41, and a fixed motor 45 is fixedly installed on the outside of the U-shaped frame 41. The output end of the fixed motor 45 is connected to a Z-shaped rod 451 through an axis, and one end of the Z-shaped rod 451 passes through the semi-arc groove 411 and is fixedly connected to the side of the support bar 32.

[0031] A fixed column 322 is movably installed inside the support bar 32, and connecting columns 323 are fixedly installed at both ends of the fixed column 322. The two connecting columns 323 are fixedly connected to the inner side of the U-shaped frame 41. An air groove 3231 is opened through the connecting column 323 and the air groove 3231. The air groove 3231 is connected to the air hole 412, and the structure for sucking gas is fixedly installed inside the support bar 32.

[0032] Specifically, the connecting column 323 is fixedly connected to the U-shaped frame 41, and the support bar 32 does not contact the inner wall of the U-shaped frame 41. Therefore, under the electric drive of the fixed motor 45, the Z-shaped rod 451 drives the inner cavity 324 to rotate inside the U-shaped frame 41, and the rotating inner cavity 324 drives the L-shaped handrest plate one 31 and the L-shaped handrest plate two 33 to rotate until the L-shaped handrest plate two 33 faces upward. The convertible L-shaped handrest plate one 31 and the L-shaped handrest plate two 33 can be applicable to different arm surgeries of different patients.

[0033] Embodiment 2: As Figure 8 shown, compared with Embodiment 1, another implementation manner of the present invention is as follows: an inner cavity 324 and two cylindrical grooves 321 are provided inside the support bar 32. The fixing column 322 is installed inside the cylindrical groove 321 and the inner cavity 324, and the structure for sucking gas is fixedly installed above the fixing column 322 and is inside the inner cavity 324.

[0034] The structure for sucking gas is a sucking assembly 325. The sucking assembly 325 is fixedly installed above the fixing column 322, the sucking assembly 325 is arranged upward, and the suction port of the sucking assembly 325 faces the corresponding ergonomic wrist pad 311.

[0035] The sucking assembly 325 includes a fixed air pump 3251 fixedly installed above the fixing column 322. The suction end of the fixed air pump 3251 is fixedly installed with an L-shaped air pipe 3253, and the air outlet end of the fixed air pump 3251 is fixedly installed with a guide air pipe 3252.

[0036] One end of the L-shaped air pipe 3253 is arranged upward and faces the corresponding ergonomic wrist pad 311, and one end of the guide air pipe 3252 is communicated with the inside of the fixing column 322.

[0037] Specifically, the connecting column 323 and the cylindrical groove 321 are fixedly installed inside the U-shaped frame 41. The support bar 32 rotates around the connecting column 323. That is, when adjusting the orientations of the first L-shaped handrest plate 31 and the second L-shaped handrest plate 33, the fixed column 322 and the suction assembly 325 remain stationary. When the first L-shaped handrest plate 31 and the second L-shaped handrest plate 33 are switched, the L-shaped air tube 3253 always faces the bottom of the corresponding ergonomic wrist pad 311. The patient's wrist is placed on the ergonomic wrist pad 311. The elastic setting of the ergonomic wrist pad 311 can improve the patient's comfort and provide support for the patient's wrist. However, in some cases, the patient may sweat due to tension, anxiety, and fear during the operation. Since the part of the ergonomic wrist pad 311 for wrist support adopts a wrapped structure for the support function, the heat dissipation is slow, and the wrist may become slippery. To avoid this situation, by starting the fixed air pump 3251, the L-shaped air tube 3253 generates suction. For example, when the first L-shaped handrest plate 31 is above the L-shaped air tube 3253, the L-shaped air tube 3253 generates suction to work on the inside of the ergonomic wrist pad 311 and the multiple through holes provided inside the ergonomic wrist pad 311 below the ergonomic wrist pad 311. That is, the multiple pore structures inside the ergonomic wrist pad 311 generate a suction air flow direction to quickly dissipate heat from the patient's wrist, avoiding affecting the subsequent operation process due to sweating. The suction gas is introduced into the air groove 3231 in the fixed column 322 through the L-shaped air tube 3253 and the air guide tube 3252, and then the gas is introduced to the outside through the air groove 3231 and the air hole 412. The suction wind force will not act on the patient or the doctor, avoiding affecting the operation process. And when the first L-shaped handrest plate 31 and the second L-shaped handrest plate 33 are rotated and switched, only one set of fixed fixed air pumps 3251 is needed to perform the suction function on the first L-shaped handrest plate 31 or the second L-shaped handrest plate 33 when required for work.

[0038] Working principle: When a patient needs to undergo a radial artery intervention, first let the patient lie on the mobile stretcher board 13, and then determine the arm of the patient that needs to undergo the operation. When the operation needs to be performed on the patient's left arm, push the lifting handrest device 2 to make it close to the left side of the DSA platform 1 and be detachably fixed to the DSA platform 1, that is, the first L-shaped handrest plate 31 is connected to the mobile stretcher board 13. At this time, the lifting handrest device 2 and the DSA platform 1 form an integral body. The patient's left hand is placed on the first L-shaped handrest plate 31 with an L-shaped panel, and the patient's wrist is placed on the ergonomic wrist pad 311 and fixed by the restraint belt 312. Subsequently, the operation is carried out in cooperation with the medical component 14. When the operation needs to be performed on the right arm of different patients, disassemble to separate the DSA platform 1 and the lifting handrest device 2, push the lifting handrest device 2 to move it close to the right side of the DSA platform 1, and drive the first L-shaped handrest plate 31 and the second L-shaped handrest plate 33 to rotate through the rotational setting of the support bar 32 inside the U-shaped frame 41, so that the second L-shaped handrest plate 33 faces upward. Continue to push the lifting handrest device 2 to make the second L-shaped handrest plate 33 be detachably installed on the other side of the mobile stretcher board 13, thereby forming an integral body. The patient's right hand is placed on the second L-shaped handrest plate 33 with an L-shaped panel, and the patient's wrist is placed on the ergonomic wrist pad 311 and fixed by the restraint belt 312. Subsequently, the operation is carried out in cooperation with the medical component 14. The mobile lifting handrest device 2 can be assembled with the DSA platform 1, and can be flexibly used to place the left and right arms of different patients. The elastic setting of the ergonomic wrist pad 311 conforms to ergonomics, thereby adapting to the patient's wrist, providing wrist support, and avoiding the influence of the discomfort of the arm on the surgical effect. A structure for sucking gas is also provided inside the support bar 32, and the gas inside the ergonomic wrist pad 311 can be sucked through a plurality of uniformly distributed through holes, reducing the heat generated by the wrapping of the patient's wrist and further improving the comfort of the patient's arm placement.

[0039] The connecting column 323 and the cylindrical groove 321 are fixedly installed inside the U-shaped frame 41. The support bar 32 rotates around the connecting column 323. That is, when adjusting the orientations of the first L-shaped handrest plate 31 and the second L-shaped handrest plate 33, the fixed column 322 and the suction assembly 325 remain stationary. When the first L-shaped handrest plate 31 and the second L-shaped handrest plate 33 are switched, the L-shaped air tube 3253 always faces the bottom of the corresponding ergonomic wrist pad 311. The patient's wrist is placed on the ergonomic wrist pad 311. The elastic setting of the ergonomic wrist pad 311 can improve the patient's comfort and provide support for the patient's wrist. However, in some cases, the patient may sweat due to tension, anxiety, and fear during the operation. And the part of the ergonomic wrist pad 311 for wrist support adopts a wrapped structure due to the support function, with slow heat dissipation and possible wrist slippage. To avoid this situation, by starting the fixed air pump 3251, the L-shaped air tube 3253 generates suction. For example, when the first L-shaped handrest plate 31 is above the L-shaped air tube 3253, the L-shaped air tube 3253 generates suction to work on the inside of the ergonomic wrist pad 311 and the multiple through holes provided inside the ergonomic wrist pad 311 below the ergonomic wrist pad 311. That is, the multiple pore structures inside the ergonomic wrist pad 311 generate a suction air flow direction to quickly dissipate heat from the patient's wrist and avoid affecting the subsequent operation process due to sweating. The suctioned gas is introduced into the air groove 3231 in the fixed column 322 through the L-shaped air tube 3253 and the air guide tube 3252, and then the gas is introduced into the outside through the air groove 3231 and the air hole 412. The suction wind force will not act on the patient or the doctor, avoiding affecting the operation process. And when the first L-shaped handrest plate 31 and the second L-shaped handrest plate 33 are rotated and switched, only one set of fixed fixed air pumps 3251 is needed to perform the suction function on the first L-shaped handrest plate 31 or the second L-shaped handrest plate 33 when required for work.
