Description

Technical Field

[0001] The present invention relates to the technical field of electrocardiograph equipment, and particularly to a special trolley for an electrocardiograph with a stable structure. Background Art

[0002] An electrocardiograph can automatically record the bioelectric signals generated by myocardial excitation during heart activity, and it is a commonly used medical electronic instrument for clinical diagnosis and scientific research. Before the heart beats, the myocardium is first excited, and a weak current is generated during the excitation process. This current is conducted through human tissues to various parts. Due to the different tissues of different parts of the body and the different distances between each part and the heart, different potential changes are shown at various parts of the body surface. The relationship between the surface potential and time generated by the electrical activity in the human heart is called an electrocardiogram, and an electrocardiograph is an instrument for recording these physiological electrical signals. Generally in China, electrocardiographs are classified according to the number of synchronous output channels of the recorder into: single-channel, three-channel, six-channel, and twelve-channel electrocardiographs, etc. The heart is the power device for the blood circulation in the human body. It is precisely because the heart continuously and automatically performs rhythmic contraction and relaxation activities that the blood keeps flowing in the closed circulatory system, maintaining life. Before and after the heart beats, the myocardium is excited, and a weak bioelectric current is generated during the excitation process. In this way, each cardiac cycle of the heart is accompanied by bioelectric changes, and these bioelectric changes can be transmitted to various parts of the body surface. Due to the different tissues of different parts of the body and the different distances from the heart, the potentials shown by the electrocardiogram signals at different parts of the body are also different.

[0003] For example, the patent document with the publication number CN 213606415 U discloses a special trolley for an electrocardiograph, which relates to the technical field of medical appliances. It includes a special trolley for an electrocardiograph, which includes a box body and a lifting platform. The top edge of the box body is provided with a handrail, and the handrail is welded to the box body. A protective plate is installed at the top edge of the box body, and a wire inlet is provided on the protective plate. One side of the box body is provided with a wire outlet, and a special box for lead wires is provided below the wire outlet, and the special box for lead wires is welded to the box body. The inside of the box body is movably connected to the lifting platform through a sliding track. The upper surface of the lifting platform is provided with a storage groove for the electrocardiograph. The center of the lower surface of the lifting platform is fixedly connected with a threaded sleeve, and a threaded lifting rod is threadedly connected inside the threaded sleeve. The outer surface of the threaded lifting rod is fixedly connected with a driven gear, and the outer surface of the driven gear meshes with a driving gear. The axis of the driving gear is movably connected to the output end of the motor through a connecting rod. Universal wheels are installed at the bottom of the box body.

[0004] However, when this structure is actually used in an electrocardiograph, due to the limitations of its own structure, it can often only be used to simply move the electrocardiograph with a special cart. However, the special cart often needs to carry control equipment and equipment for powering the electrocardiograph, resulting in a relatively large volume of its own. The usable area on both sides of some hospital beds is limited. It is often necessary to place the entire electrocardiograph equipment at the end of the bed for use, and it cannot be better adapted and accurately used beside the bed. Moreover, the electrocardiograph equipment cannot be more stably protected, and at the same time, the equipment cannot perform a more stable positioning operation on the entire moving equipment, unable to meet the daily use requirements. Therefore, it is urgent to design a special cart for an electrocardiograph with a stable structure to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a special cart for an electrocardiograph with a stable structure to solve the problems raised in the above background technology. When the existing structure is actually used in an electrocardiograph, due to the limitations of its own structure, it can often only be used to simply move the electrocardiograph with a special cart. However, the special cart often needs to carry control equipment and equipment for powering the electrocardiograph, resulting in a relatively large volume of its own. The usable area on both sides of some hospital beds is limited. It is often necessary to place the entire electrocardiograph equipment at the end of the bed for use, and it cannot be better adapted and accurately used beside the bed. Moreover, the electrocardiograph equipment cannot be more stably protected, and at the same time, the equipment cannot perform a more stable positioning operation on the entire moving equipment, unable to meet the daily use requirements.

[0013] Preferably, a first sliding cover is movably connected to one side of the surface of the equipment rack, a second sliding cover is movably connected to the other side of the surface of the equipment rack, and a sealing strip is arranged between the first sliding cover and the second sliding cover.

[0014] Preferably, a docking strip is arranged on the front of the connecting rod, a wiring back rack is arranged on the back of the connecting rod, and damping side strips are fixedly connected to both sides of the connecting rod.

[0015] Preferably, the upper bracket, the connecting rod and the lower bracket are adapted to the installation cabinet, the upper limiting frame and the lower limiting frame.

[0016] Compared with the prior art, the beneficial effects of the present invention are: The electrocardiograph special trolley with a stable structure, through the installed installation cabinet, upper limit bracket, upper bracket, equipment rack, electrocardiograph equipment body, connecting rod, lower bracket, moving rack, movable shaft, positioning cover, tightening airbag, tightening plate, second universal wheel, third air control pump, suction net groove, central support airbag, support top plate, control panel, instrument rack, limit slide rail, first sliding cover, second sliding cover, sealing strip, docking strip, wiring back rack and damping side strip, can enable the device to perform a more stable electrocardiogram detection operation for the electrocardiograph equipment body on the surface of the equipment rack and the patient on the hospital bed. During the actual use process, the staff first slides and unfolds the first sliding cover and the second sliding cover that are connected to the left and right sides of the electrocardiograph equipment body on the surface of the equipment rack along the limit slide rail, quickly exposing the electrocardiograph equipment body on the surface of the equipment rack. The sealing between the first sliding cover and the second sliding cover by the sealing strip can provide a more secure and reliable protection for the electrocardiograph equipment body. Then, through the control panel and instrument rack on the front and back sides of the electrocardiograph equipment body, the electrocardiogram monitoring of the patient can be realized. At this time, when the area on both sides of the patient's hospital bed is small and the entire installation cabinet cannot enter, the upper bracket, connecting rod and lower bracket can be adjusted by moving the moving rack at the bottom as a whole, and then removed from the inside of the installation cabinet, upper limit bracket and lower limit bracket. Then, the relatively small volume of the upper bracket, connecting rod and lower bracket as a whole can be processed and adapted to enter both sides of the hospital bed, enabling the electrocardiograph equipment body on the surface of the equipment rack to be used more adaptively with the patient. The entire installation cabinet only needs to be placed at the end of the bed, more adaptively meeting the electrocardiogram examination needs in a smaller ward area. At the same time, when the upper bracket, connecting rod and lower bracket as a whole are reset after use, the damping side strips on both sides of the connecting rod can be used for tight damping positioning on both sides of the inner wall of the installation cabinet, and the wiring back rack is used to connect the wiring of the electrocardiograph equipment body. Finally, the positioning cover is movably buckled on the front of the installation cabinet through the movable shaft, and the second air control pump at the bottom of the positioning cover can be started to inflate and expand the tightening airbag, so that the tightening plate at one end thereof is adaptively abutted against the docking strip on the front of the connecting rod to perform the docking and fastening of the entire device, reflecting the practicality of the device design.

[0017] The special trolley for electrocardiograph with a stable structure further improves the overall use effect of the equipment through the set back frame, wire arranging frame, lower limit frame, first air control frame, second air control frame, retractable inclined cover, first air control pump, side retractable airbag, first universal wheel, wire winding roller frame, wire outlet, wire inlet, wire arranging side seat, wire arranging side groove, control unit, storage power unit, fan frame, heat dissipation mesh groove and second air control pump. During daily use, the staff can install the electrocardiograph equipment body and the control unit and storage power unit used to supply power to the electrocardiograph equipment body on both sides inside the back frame of the installation cabinet. At this time, the control unit and storage power unit can start the fan frame on the back of the back frame to perform the air suction and heat dissipation operation from the heat dissipation mesh groove, and the wiring of the control unit and storage power unit can pass through the lower limit frame. At this time, the wire winding roller frame inside the lower limit frame can cooperate with the wire outlet and wire inlet at both ends to perform the appropriate wire winding and unwinding operation to meet the regular arrangement operation of the wire when the upper bracket, connecting rod and lower bracket are separated from the installation cabinet, upper limit frame and lower limit frame. Then, it can be further combined with the wire arranging operation through the wire arranging side groove of the wire arranging side seat on one side of the wire arranging frame and be hidden and connected to the wiring back frame inside the connecting rod. After the bottom of the daily moving frame is moved to the designated position through the second universal wheel, the third air control pump can be started to suck air from the air suction mesh groove to push the support top plate at the bottom of the central support airbag against the ground to complete the support operation. At the same time, at the first air control frame and the second air control frame on both sides of the lower limit frame, the first air control frame and the second air control frame can also be accurately sucked air from both ends by stepping on the first air control pump and then inflated to the side retractable airbag inside the retractable inclined cover, and also be pushed against the ground to complete the support operation, so as to ensure the more stable overall movement and fixed-point use operation of the electrocardiograph equipment body, reflecting the comprehensiveness of the equipment design.

And the wiring of the control unit 25 and the storage battery unit 26 can pass through the lower limit frame 13. At this time, inside the lower limit frame 13, the wire winding roller frame 20 can cooperate with the wire outlet 21 and the wire inlet 22 at both ends to perform appropriate wire winding and unwinding operations to meet the regular arrangement operation of the wires when the upper support bracket 3, the connecting rod 6 and the lower support bracket 7 are separated from the installation cabinet 1, the upper limit frame 2 and the lower limit frame 13.

[0023] Working principle: When in use, the user first slides and unfolds the first sliding cover 40 and the second sliding cover 41 which are connected to the left and right of the electrocardiogram device body 5 on the surface of the device rack 4 along the limiting slide rail 39, quickly exposing the electrocardiogram device body 5 on the surface of the device rack 4. The seal between the first sliding cover 40 and the second sliding cover 41 can provide a more secure and reliable protection for the electrocardiogram device body 5 through the sealing strip 42. Then, through the control panels 37 and instrument racks 38 on the front and back sides of the electrocardiogram device body 5, the electrocardiogram monitoring of the patient is realized. At this time, when the area on both sides of the patient's hospital bed is small and the entire installation cabinet 1 cannot enter, the upper support bracket 3, the connecting rod 6, and the lower support bracket 7 can be adjusted as a whole by the moving frame 8 at the bottom. Then, they are moved out from the inside of the installation cabinet 1, the upper limit frame 2, and the lower limit frame 13. Then, the relatively small volume of the upper support bracket 3, the connecting rod 6, and the lower support bracket 7 as a whole can be processed and adapted to enter both sides of the hospital bed, enabling the electrocardiogram device body 5 on the surface of the device rack 4 to be used more adaptively with the patient. The entire installation cabinet 1 only needs to be placed at the end of the bed, which is more adaptable to meet the electrocardiogram examination use under a smaller ward area. At the same time, when the upper support bracket 3, the connecting rod 6, and the lower support bracket 7 are reset after use, the damping side strips 45 on both sides of the connecting rod 6 can be used for firm damping positioning on both sides of the inner wall of the installation cabinet 1, and the wiring back frame 44 connects the wires of the electrocardiogram device body 5. Finally, the positioning cover 10 is movably buckled on the front of the installation cabinet 1 through the movable shaft 9, and the second air control pump 29 at the bottom of the positioning cover 10 can be started to inflate and expand the top tight airbag 30, so that the top tight plate 31 at one end thereof is adaptively abutted against the docking strip 43 on the front of the connecting rod 6 to perform the docking and fastening of the entire device. During the daily use process, the staff can install the control unit 25 and the battery storage unit 26 for controlling the electrocardiogram device body 5 and powering the electrocardiogram device body 5 on both sides inside the back frame 11 inside the installation cabinet 1. At this time, the control unit 25 and the battery storage unit 26 can perform the air suction and heat dissipation operation from the heat dissipation mesh groove 28 by starting the blower frame 27 on the back of the back frame 11, and the wiring of the control unit 25 and the battery storage unit 26 can pass through the lower limit frame 13. At this time, the inside of the lower limit frame 13 can perform the appropriate wire winding and unwinding operation through the wire winding roller frame 20 in cooperation with the wire outlet 21 and the wire inlet 22 at both ends, so as to meet the neat arrangement operation of the wires when the upper support bracket 3, the connecting rod 6, and the lower support bracket 7 are separated from the installation cabinet 1, the upper limit frame 2, and the lower limit frame 13. Then, in cooperation with the wire arrangement on one side of the wire arrangement frame 12 through the wire arrangement side groove 24 of the wire arrangement side seat 23, it is hidden and connected to the wiring back frame 44 inside the connecting rod 6. After the bottom of the daily moving frame 8 is moved to the designated position through the second universal wheel 32, the third air control pump 33 can be started to suck air from the air suction mesh groove 34, and the support top plate 36 at the bottom of the central support airbag 35 is abutted against the ground to complete the support operation.Meanwhile, at the first air control frame 14 and the second air control frame 15 on both sides of the lower limit frame 13, by stepping on the first air control pump 17, the first air control frame 14 and the second air control frame 15 can accurately suck air from both ends and then inflate the air bag 18 on the inner side of the contraction inclined cover 16. Similarly, it abuts against the ground to complete the support operation, thus ensuring that the overall electrocardiogram device body 5 of the equipment moves more stably and is used at a fixed point. The above is the entire working principle of the present invention.

[0024] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
