Description

Technical Field

[0001] The invention relates to the technical field of medical equipment auxiliary devices, and in particular to an electrocardiogram monitoring circuit storage device. Background Art

[0002] ECG monitors are a very common type of medical electronic equipment used clinically. They can continuously monitor the patient's cardiac physiological parameters around the clock, serving as a basis for emergency treatment and diagnosis by medical staff. They can also monitor the patient's medication and conditions before and after surgery.

[0003] The existing ECG monitor has many lines, such as electrode lines, blood oxygen saturation monitoring lines, etc. These lines are scattered on the bed when in use, which is very messy and easy to entangle with each other. They need to be rearranged for the next use, which is troublesome and increases the labor intensity of medical staff. In addition, most of these lines are long and easy to fall to the ground when in use, causing the lines to become dirty. Therefore, a line storage device that can conveniently store the lines of ECG monitoring is urgently needed to solve the above problems. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an electrocardiogram monitoring circuit storage device to solve the problem of messy and troublesome circuit arrangement in the existing electrocardiogram monitoring circuits proposed in the above background technology.

[0005] In order to solve the above technical problems, a basic solution adopted by the present invention is: an electrocardiogram monitoring line storage device, comprising a device body, wherein a plurality of storage units for storing and releasing the line are arranged in the device body, wherein the storage unit comprises a storage cavity arranged in the middle of the device body for accommodating the line and storage mechanisms respectively arranged on both sides of the storage cavity, wherein an inlet and outlet for accommodating the line and cooperating with the storage mechanism are arranged on the device body, wherein the storage mechanism comprises a driving component for driving the line to move and a limiting component for limiting the movement of the line;

[0006] The driving assembly is arranged close to the storage chamber, the driving assembly includes a driving wheel, a driven wheel cooperating with the driving wheel and a coil spring driving the driving wheel to rotate, the driving wheel and the driven wheel are both rotatably connected to the device body, the limiting assembly is arranged close to the inlet and outlet, the limiting assembly includes an inclined plate arranged obliquely, a contact plate cooperating with the inclined plate and a pushing member for pushing the inclined plate to rotate away from the contact plate, one end of the inclined plate is rotatably connected to the device body, the other end of the inclined plate is a free end inclined toward the contact plate and toward the inlet and outlet, and a torsion spring is arranged on the inclined plate to force the inclined plate to rotate toward the storage chamber.

[0007] Furthermore, the device body includes a base and a plurality of upper seats arranged in cooperation with the retractable units, and the upper seats are detachably connected to the base.

[0008] Furthermore, the base is horizontally fixedly connected to rotating shaft one, the driving wheel is rotatably connected to rotating shaft one, the coil spring is sleeved outside rotating shaft one, one end of the coil spring is fixedly connected to rotating shaft one, and the other end of the coil spring is fixedly connected to the driving wheel, the upper seat is fixedly connected to rotating shaft two parallel to rotating shaft one, and the driven wheel is rotatably connected to rotating shaft two.

[0009] Furthermore, arc grooves are arranged on the surfaces of the driving wheel and the driven wheel, and elastic friction plates are arranged in the arc grooves.

[0010] Furthermore, the pushing member includes a pressing rod arranged on the upper seat, the inclined plate is rotatably connected to the upper seat through a rotating shaft three, the rotating shaft three is arranged parallel to the rotating shaft one, one end of the inclined plate rotatably connected to the rotating shaft three is provided with a push plate protruding along the radial direction of the rotating shaft three, the torsion spring is sleeved outside the rotating shaft three, one end of the torsion spring is fixedly connected to the rotating shaft three, and the other end of the torsion spring is fixedly connected to the inclined plate, the pressing rod is arranged horizontally, the pressing rod and the rotating shaft three space are arranged vertically, the outer end of the pressing rod is located outside the upper seat, the inner end of the pressing rod is located inside the upper seat and close to the push plate, the pressing rod is provided with a reset spring forcing the inner end of the pressing rod to move away from the push plate, and the contact plate is arranged on the base corresponding to the free end of the inclined plate.

[0011] Furthermore, the angle between the inclined plate and the horizontal plane is 70° to 80°.

[0012] Furthermore, the free end of the inclined plate is arranged in an arc shape, and an elastic friction plate is arranged on the surface of the free end of the inclined plate.

[0013] Furthermore, a fixing piece for fixing the device body to the hospital bed is arranged on the outer wall of the base.

[0014] Furthermore, the fixing member includes a magnet arranged on the outer wall of the base.

[0015] Furthermore, the fixing member includes a binding strap.

[0016] When this solution is used, when assembling the circuit on the monitor with this device, first disassemble each upper seat, respectively match the two ends of the circuit with the corresponding contact plate and the driving wheel, and fix the upper seat with the base, so that the circuit is located between the free end of the inclined plate and the contact plate, and passes between the driving wheel and the driven wheel, and the middle line body of each circuit is located in the storage cavity and the two ends of the circuit are respectively close to the corresponding inlet and outlet. At this time, the coil spring is in a natural state without being compressed. Then fix the device to a suitable position on the bed or other suitable place, and pull the circuit outward from both ends of the circuit so that one end of the circuit is connected to the corresponding port of the monitor and the other end fits the relevant part of the patient's body.

[0017] In the device, when the pressing rod is not pressed, under the elastic force of the return spring, the inner end of the pressing rod is away from the push plate on the inclined plate. Under the elastic force of the torsion spring and the inclined setting of the inclined plate, when the line moves toward the storage chamber, the inclined plate will rotate toward the driving wheel so that the free end of the inclined plate moves toward the contact plate to press the line against the contact plate and make it unable to move. At this time, the elastic force of the coil spring cannot force the driving wheel to rotate to retract the line into the storage chamber; when the line is stretched out of the device, the inclined plate will rotate away from the driving wheel so that the friction between the line and the free end of the inclined plate and the contact plate is reduced. At this time, the line can be pulled outward to extend out of the device and force the driving wheel to rotate so that the coil spring is compressed and stores energy.

[0018] When the pressing rod is pressed along the axial direction of the pressing rod, the inner end of the pressing rod squeezes the push plate on the inclined plate to force the inclined plate to rotate to overcome the elastic force of the torsion spring so that the lower end of the inclined plate leaves the line, and the line can move freely. At this time, under the elastic force of the coil spring, the driving wheel rotates to retract the excess line into the storage chamber in the device.

[0019] Compared with the prior art, the ECG monitoring circuit storage device of this solution has at least the following beneficial effects:

[0020] 1. This device can roll up part of the wires of each line in the corresponding storage cavity in the device during ECG monitoring, so as to prevent the problem that the wires fall to the ground and become dirty due to the long length of each line, and the wires become tangled and difficult to sort out.

[0021] 2. The device does not need to shrink or release the line by winding the reel, and the friction between the line and the driving wheel remains stable. The friction between the line and the reel is reduced and the line cannot be reeled in when shrinking or releasing the line by winding the line around the reel.

[0022] 3. This device adopts a split structure, which is easy and quick to disassemble and install, and is convenient for different models of monitors to be used in conjunction with the device to match the various circuits on the monitor with the device;

[0023] 4. In this device, both ends of the line can be contracted and stretched independently. When one end of the line is retracted or extended, the stress on the other end of the line will not be affected. Therefore, the storage device can be moved to a more reasonable position at any time according to the monitoring environment.

[0024] 5. This device is provided with limiter components at both ends of the line, which effectively prevents the line from being pulled and contracted by the coil spring during the monitoring process, causing the end of the line to be separated from the patient or the monitor;

[0025] 6. In this device, when the line is stretched outward, it is not restricted by the limiting component, and no special operation is required to release the restriction of the limiting component on the line. The stretching of the line is convenient and quick;

[0026] 7. When ECG monitoring is not performed, press each pressing rod, and the limit assembly releases the restriction on the circuit in the contraction direction, and the circuit is retracted into the storage cavity under the elastic force of the coil spring;

[0027] 8. In this device, each line on the monitor can be stretched and stored separately without affecting the use of other lines. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] The limit assembly is disposed close to the inlet and outlet 104, and includes an inclined plate 301, a contact plate 302 arranged in cooperation with the inclined plate 301, and a pusher for pushing the inclined plate 301 to rotate away from the contact plate 302. Figure 1 , Figure 2 As shown, the contact plate 302 is arranged on the upper surface of the base 101 corresponding to the inclined plate 301, and the inclined plate 301 is rotatably connected to the upper seat 102 through the third rotating shaft 3032. Specifically, the third rotating shaft 3032 is arranged parallel to the first rotating shaft 2011, and the third rotating shaft 3032 is fixedly connected to the upper seat 102. The upper end of the inclined plate 301 is rotatably connected to the third rotating shaft 3032, and the lower end of the inclined plate 301 is a free end inclined toward the contact plate 302 and the corresponding inlet and outlet 104. The lower end of the inclined plate 301 is arranged in an arc shape, and an elastic friction sheet 304 is attached to the lower end surface of the inclined plate 301. In this embodiment, the inclined plate 3 01 and the horizontal plane have an angle of 70° to 80°, preferably 75°, a push plate 3011 is protruded radially along the upper end of the inclined plate 301 along the rotation axis three 3032, and a torsion spring (not shown) is arranged on the inclined plate 301 forcing the lower end of the inclined plate 301 to rotate toward the receiving chamber 103, the torsion spring is sleeved on the outer wall of one end of the rotation axis three 3032, one end of the torsion spring is fixedly connected to the rotation axis three 3032, and the other end of the torsion spring is fixedly connected to the inclined plate 301, and the elastic force of the torsion spring forces the lower end of the inclined plate 301 to rotate toward the receiving chamber 103 so that the lower end of the inclined plate 301 contacts the upper surface of the contact plate 302 and generates a certain pressure on the contact plate 302.

[0047] The pushing member includes a pressing rod 3031 arranged on the upper seat 102, the pressing rod 3031 is arranged horizontally, the pressing rod 3031 and the rotating shaft 3032 are in a spatial vertical relationship, the outer end of the pressing rod 3031 is located outside the upper seat 102, the inner end of the pressing rod 3031 is located inside the upper seat 102 and is arranged close to the push plate 3011, a return spring 3033 is arranged on the pressing rod 3031, the return spring 3033 is sleeved on the inner end outer wall of the pressing rod 3031 and is coaxially arranged with the pressing rod 3031, one end of the return spring 3033 close to the push plate 3011 is fixedly connected to the pressing rod 3031, and the other end of the return spring 3033 is fixedly connected to the inner wall of the upper seat 102, and under the elastic force of the return spring 3033, the inner end of the pressing rod 3031 is away from the push plate 3011.

[0048] In this solution, when assembling the circuit 50 on the monitor with the device, first disassemble each upper seat 102, match the two ends of the circuit 50 with the corresponding contact plate 302 and the driving wheel 201 respectively, and fix the upper seat 102 with the base 101, so that the circuit 50 is located between the free end of the inclined plate 301 and the contact plate 302, and between the driving wheel 201 and the driven wheel 202, and the middle line body of each circuit 50 is located in the storage cavity 103 and the two ends of the circuit 50 are respectively close to the corresponding inlet and outlet 104, at this time, the coil spring 203 is in a natural state without being compressed, and then fix the device body to a suitable position on the edge of the bed or other suitable place, and pull the circuit 50 outward from the two ends of the circuit 50 so that one end of the circuit 50 is connected to the corresponding port of the monitor and the other end is in contact with the relevant part of the patient's body.

[0049] In the present device, when the pressing rod 3031 is not pressed, under the elastic force of the return spring 3033, the inner end of the pressing rod 3031 is away from the push plate 3011 on the inclined plate 301. Under the elastic force of the torsion spring and the inclined setting of the inclined plate 301, when the circuit 50 moves toward the storage chamber 103, the inclined plate 301 rotates toward the driving wheel 201 so that the free end of the inclined plate 301 moves toward the contact plate 302 to press the circuit 50 against the contact plate 302. When the circuit 50 is pulled out of the device body, the inclined plate 301 will rotate away from the driving wheel 201 so that the friction between the circuit 50 and the free end of the inclined plate 301 and the contact plate 302 is reduced. At this time, the circuit 50 can be easily pulled outward to extend out of the device body and the driving wheel 201 is forced to rotate so that the coil spring 203 is compressed and energy is stored.

[0050] When it is necessary to reel in the line, the pressing rod 3031 is pressed down along the axis direction of the pressing rod 3031. Figure 6 As shown, the inner end of the pressing rod 3031 squeezes the push plate 3011 on the inclined plate 301 to force the inclined plate 301 to rotate by overcoming the elastic force of the torsion spring so that the lower end of the inclined plate 301 leaves the line 50, and the line 50 can move freely. At this time, under the elastic force of the coil spring 203, the driving wheel 201 rotates to retract the excess line 50 into the storage chamber 103 in the device.
