Description

Technical Field

[0001] The utility model relates to the technical field of electrocardiogram monitoring equipment, and particularly relates to a lead wire retracting and releasing mechanism and an electrocardiogram monitor thereof. Background Technique

[0002] An electrocardiogram monitor is an essential monitoring device in hospitals, which can monitor physiological indicators of patients in real time, such as electrocardiogram, heart rate, blood oxygen saturation, respiration, body temperature, and blood pressure. When the above physiological indicators are abnormal, an alarm will be issued to prompt medical staff to intervene in a timely manner.

[0003] Since it is necessary to monitor multiple physiological indicators of patients, different monitoring probes are required to be connected to the corresponding parts of the patient's body to monitor different physiological indicators of the patient. In order to facilitate the connection of these monitoring probes to the electrocardiogram monitor, lead wires are used. In this way, only by connecting the main wire to the electrocardiogram monitor, all monitoring probes can be connected to the electrocardiogram monitor through the splitter head, effectively simplifying the connection work of the electrocardiogram monitor. However, due to the large number and long length of the splitter lines on the lead wire of the electrocardiogram monitor, when monitoring or storing and placing patients, multiple splitter lines are easily tangled together, which will not only affect the connection and use of various monitoring probes, but also may hinder the use of other monitoring and rescue equipment.

[0004] The Chinese utility model patent with the patent application number CN202310730586.6 records an electrocardiogram monitor lead wire retracting and releasing device, which clamps the lead wire through the set clip. When the lead wire needs to be released, press the upper splint and the lower splint to open the lower splint and the upper splint. After releasing the lead wire, close the lower splint and the upper splint, and clamp the lead wire remaining on the winding shaft by the middle clamping arm of the clamping teeth; when the lead wire is retracted, press the upper splint and the lower splint to open the lower splint and the upper splint. After retracting the lead wire, close the lower splint and the upper splint again, and clamp the lead wire wound on the winding shaft by the two clamping arms on both sides of the clamping teeth. However, when retracting and releasing each splitter line of the lead wire in the above device, the staff needs to always press down the upper splint with one hand to loosen the splitter line, which brings trouble to the retracting and releasing work of the lead wire. Content of the Utility Model

[0005] The purpose of this application is to provide a lead wire retracting and releasing mechanism and an electrocardiogram monitor thereof, so as to solve the problem that when retracting and releasing each splitter line of the lead wire as mentioned in the above background technique, the staff needs to always press down the upper splint with one hand to loosen the splitter line, which brings trouble to the retracting and releasing work of the lead wire.

[0006] To achieve the above object, the present application provides the following technical solution: A lead wire retracting and extending mechanism, including a rotating shaft, the right end of the rotating shaft is fixedly connected to a first knob, a plurality of vertical plates are fixedly sleeved on the outer peripheral surface of the rotating shaft at equal intervals, a rotating rod is rotatably connected to the right side surface of the leftmost vertical plate, the right end of the rotating rod penetrates through other vertical plates and extends to the right side of the rightmost vertical plate, the rotating rod is rotatably connected to the vertical plates, a plurality of pressing plates are fixedly sleeved on the outer peripheral surface of the rotating rod, and the plurality of pressing plates are respectively located in the gaps between the plurality of vertical plates. It further includes a clamping control component provided on the right side surface of the rightmost vertical plate for controlling the pressing plates. The clamping control component includes a connecting block fixedly connected to the left end of the rotating rod, a first torsion spring is fixedly connected between the left side surface of the connecting block and the right side surface of the rightmost vertical plate, and the clamping control component further includes a screw rod threadedly inserted on the right side surface of the rightmost vertical plate, and the screw rod can block the rotation of the connecting block.

[0007] Preferably, the clamping control component further includes a rotating arm rotatably connected to the top of the connecting block through a second torsion spring and a round rod. A baffle is fixedly connected to the front side of the top of the connecting block, and the back surface of the baffle can abut against the front surface of the rotating arm. The advantage of this setting is that when the staff rotates the connecting block counterclockwise, when the rotating arm touches the screw rod, the rotating arm will rotate clockwise until it passes over the screw rod, and then the rotating arm will reset under the elastic force of the second torsion spring, and then the connecting block is released. The connecting block will rotate clockwise under the elastic force of the first torsion spring until the rotating arm touches the screw rod again. At this time, due to the blocking of the baffle, the rotating arm cannot rotate counterclockwise, thereby realizing the limitation of the rotating rod and the pressing plate. In this way, the pressing plate can be kept in a state of loosening the lead wire branch, so as to facilitate the staff to retract and extend the lead wire branch, and simplify the operation of the staff to connect or store the monitoring probe.

[0008] Preferably, it further includes a plurality of wire winding rollers rotatably connected to the outer peripheral surface of the rotating shaft at equal intervals. The number of the plurality of wire winding rollers is equal to and corresponds to the number of the plurality of pressing plates one by one. Two third torsion springs are symmetrically fixedly connected between the left and right side surfaces of the wire winding roller and the side surfaces of the adjacent two vertical plates. The advantage of this setting is that after the pressing plate loosens the lead wire branch, and then the staff removes the monitoring probe connected to the branch from the patient, the wire winding roller will automatically rotate and wind up the branch under the elastic force of the third torsion spring, further simplifying the storage work of the lead wire branch and improving the practicability of the lead wire retracting and extending mechanism.

[0009] Preferably, it also includes an auxiliary component for accelerating the clamping of the lead wire branches, the auxiliary component includes a clamping plate rotatably connected to the back of the pressure plate through two ear plates, a round rod and a fourth torsion spring, the auxiliary component also includes a baffle rod, the outer peripheral surface of the baffle rod is in contact with the back of the clamping plate, and the auxiliary component also includes a driving unit for driving the baffle rod to move upward. The advantage of such an arrangement is that the lead wire branches on multiple winding rollers can be clamped or released separately through multiple clamping plates, thereby facilitating the staff to independently store or connect each detection probe, so that the lead wire branches will not interfere with each other, greatly improving the practicality of the retractable mechanism.

[0010] Preferably, the driving unit includes two sliding sleeves symmetrically fixedly connected to the back of the pressure plate, two sliding rods symmetrically slidably connected in the two sliding sleeves, two limit sleeves symmetrically fixedly sleeved on the outer circumference of the two sliding rods, the blocking rod is fixedly connected to the top of the two sliding rods, and a lever is fixedly connected between the bottom ends of the two sliding rods. The advantage of such a setting is that after the staff connects a monitoring probe to the patient's body, they only need to swing the lead wire branch connected to the monitoring probe upwards, so that they can push the lever upwards, thereby pushing the blocking rod upwards through the sliding rod, so that the blocking rod can be separated from the clamping plate, and at this time the clamping plate rotates and clamps the lead wire branch under the elastic force of the fourth torsion spring, so that the staff does not need to move to the electrocardiogram monitor to perform the clamping operation, which further simplifies the clamping operation of the lead wire branch and maximizes the practicality of the retracting and releasing mechanism.

[0011] An electrocardiogram monitor comprises an outer shell, a bracket is fixedly connected to the bottom of the outer shell, an L-shaped hook is fixedly connected to the bottom of the outer shell, a transducer, a signal processing module, a control module and an alarm device are arranged inside the outer shell, and the tops of a plurality of vertical plates are fixedly connected to the bottom of the outer shell. The advantage of such a setting is that a lead wire bus can be hung on the L-shaped hook, so that the entire lead wire can be effectively limited and placed, thereby preventing the lead wire from being scattered and preventing the lead wire from hindering the use of other monitoring and medical equipment.

[0012] In summary, the technical effects and advantages of the utility model are:

[0013] 1. In the utility model, a clamping control component is provided to enable multiple pressure plates to be kept in a loosened or clamped state for a long time, so that the staff does not need to control the pressure plates to be in a loosened state all the time, thereby freeing the hands of the staff and facilitating the staff to reel in or unreel each lead wire branch line, effectively improving the practicality and reliability of the retractable mechanism.

[0014] 2. In the present utility model, after a staff member connects a monitoring probe to a patient's body, they only need to swing the branch lead wire connected to the monitoring probe upwards. In this way, they can move the lever upwards to clamp the branch lead wire with the clamping plate, eliminating the need for the staff member to move to the electrocardiogram monitor for clamping operations. This further simplifies the clamping operation of the branch lead wire and maximizes the practicality of the retractable mechanism. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1

[0025] Please refer to Figures 1-6 A lead wire winding and unwinding mechanism as shown, including a rotating shaft 1. The right end of the rotating shaft 1 is fixedly connected to a first knob 101. A plurality of vertical plates 2 are fixedly sleeved on the outer peripheral surface of the rotating shaft 1 at equal intervals. A rotating rod 3 is rotatably connected to the right side surface of the leftmost vertical plate 2. The right end of the rotating rod 3 penetrates through the other vertical plates 2 and extends to the right side of the rightmost vertical plate 2. The rotating rod 3 is rotatably connected to the vertical plates 2. A plurality of pressing plates 4 are fixedly sleeved on the outer peripheral surface of the rotating rod 3. The plurality of pressing plates 4 are respectively located in the gaps between the plurality of vertical plates 2. It further includes a clamping control assembly 5 provided on the right side surface of the rightmost vertical plate 2 for controlling the pressing plates 4. The clamping control assembly 5 includes a connecting block 51 fixedly connected to the left end of the rotating rod 3. A first torsion spring 52 is fixedly connected between the left side surface of the connecting block 51 and the right side surface of the rightmost vertical plate 2. The clamping control assembly 5 further includes a screw rod 53 threadedly inserted into the right side surface of the rightmost vertical plate 2. The screw rod 53 can block the rotation of the connecting block 51.

[0026] Refer to Figure 3 、 4 And 6, the clamping control assembly 5 further includes a rotating arm 55 rotatably connected to the top of the connecting block 51 through a second torsion spring 54 and a round rod. A baffle 56 is fixedly connected to the front side of the top of the connecting block 51. The back surface of the baffle 56 can be in contact with the front surface of the rotating arm 55.

[0027] Specifically, when the staff rotates the connecting block 51 counterclockwise, when the rotating arm 55 touches the screw rod 53, the rotating arm 55 will rotate clockwise until it passes over the screw rod 53. Then the rotating arm 55 will reset under the elastic force of the second torsion spring 54. Then the connecting block 51 is released, and the connecting block 51 will rotate clockwise under the elastic force of the first torsion spring 52 until the rotating arm 55 touches the screw rod 53 again. At this time, due to the blocking of the baffle 56, the rotating arm 55 cannot rotate counterclockwise, thereby realizing the limitation of the rotating rod 3 and the pressing plates 4. In this way, the pressing plates 4 can be kept in a state of loosening the lead wire branch, so as to facilitate the staff to wind and unwind the lead wire branch, and simplify the operation of the staff for connecting or storing the monitoring probe.

[0028] Embodiment 2

[0029] According to Embodiment 1, please refer to Figure 3 And Figure 4, further comprising a plurality of wire winding rollers 6 rotatably connected to the outer peripheral surface of the rotating shaft 1 at equal intervals. The number of the plurality of wire winding rollers 6 is equal to and corresponds one by one to the number of the plurality of pressing plates 4. Two third torsion springs 7 are symmetrically and fixedly connected between the left and right side surfaces of the wire winding roller 6 and the side surfaces of two adjacent vertical plates 2.

[0030] Specifically, after the pressing plate 4 releases the lead wire split, and then the staff removes the monitoring probe connected to the split from the patient. Under the elastic force of the third torsion spring 7, the wire winding roller 6 will automatically rotate and wind up the split, further simplifying the storage work of the lead wire split and improving the practicability of the lead wire winding and unwinding mechanism.

[0031] Reference Figures 3-5 , further comprising an auxiliary assembly 8 for accelerating the clamping of the lead wire split. The auxiliary assembly 8 includes a clamping plate 82 rotatably connected to the back surface of the pressing plate 4 through two ear plates, a round rod and a fourth torsion spring 81.

[0032] Specifically, the plurality of clamping plates 82 are used to individually clamp or release the lead wire splits on the plurality of wire winding rollers 6, so as to facilitate the staff to independently store or connect each detection probe, and prevent the lead wire splits from interfering with each other, greatly improving the practicability of the winding and unwinding mechanism.

[0033] Embodiment 3

[0034] According to Embodiment 1 or 2, please refer to Figure 5 , the driving unit 84 includes two sliding sleeves 841 symmetrically and fixedly connected to the back surface of the pressing plate 4. Two sliding rods 842 are symmetrically and slidably connected in the two sliding sleeves 841. Two limiting sleeves 843 are symmetrically and fixedly sleeved on the outer peripheral surfaces of the two sliding rods 842. The stop rod 83 is fixedly connected to the tops of the two sliding rods 842. A toggle lever 844 is fixedly connected between the bottoms of the two sliding rods 842.

[0035] Specifically, after the staff connects a monitoring probe to the patient's body, they only need to swing the lead wire split connected to the monitoring probe upward, so as to toggle the toggle lever 844 upward, thereby pushing the stop rod 83 upward through the sliding rod 842, so that the stop rod 83 is separated from the clamping plate 82. At this time, the clamping plate 82 rotates under the elastic force of the fourth torsion spring 81 and clamps the lead wire split, so that the staff does not need to move to the electrocardiogram monitor for clamping operation, further simplifying the clamping operation of the lead wire split and maximizing the practicability of the winding and unwinding mechanism.

[0036] Please refer to Figure 1 and Figure 2An electrocardiogram monitor shown in the figure includes a housing 9. A bracket 10 is fixedly connected to the bottom of the housing 9, and an L-shaped hook 11 is fixedly connected to the bottom of the housing 9. A transducer, a signal processing module, a control module and an alarm device are provided inside the housing 9.
