[0016] A groove is formed on the circumferential outer wall of the adjustment seat along the axial direction of the adjustment seat;

[0017] The bottom plate of the box seat is formed with a convex block inserted into the groove.

[0018] Furthermore, one end of the rotating rod located outside the box seat is connected to a hand wheel.

[0019] Furthermore, the sleeve is a tubular structure with a closed top, a connecting pipe is provided between the sleeve and the top plate of the box seat, the connecting pipe is fixedly connected to the box seat and passes through the sleeve and is rotatably connected to the sleeve;

[0020] The interior of the adjustment seat is hollow;

[0023] The exhaust assembly is connected to the other end of the air guide pipe to adjust the air pressure in the adjustment seat.

[0024] Furthermore, the exhaust assembly comprises:

[0025] The pumping cylinder is a cylindrical structure with one end closed and is fixedly connected to the box seat;

[0026] A sealing plug, located in the pumping tube and pressed against the inner wall of the pumping tube to form a pumping cavity;

[0027] A push-pull plate, fixedly connected to the sealing plug;

[0028] A push-pull rod is connected to the push-pull plate to enable the sealing plug to slide in the exhaust tube to adjust the size of the exhaust cavity.

[0029] Furthermore, the push-pull rod is parallel to the rotating rod;

[0030] A transmission member is provided between the push-pull rod and the rotating rod, and the transmission member comprises:

[0031] A screw rod, the screw rod is parallel to the rotating rod, and the screw rod is rotatably connected to the box seat;

[0033] The slab gear set comprises a first slab gear sleeved on one end of the screw rod and a second slab gear sleeved on the rotating rod, wherein the first slab gear is meshed with the second slab gear.

[0034] Furthermore, the suction cup is made of rubber.

[0035] Furthermore, the box seat is provided with heat dissipation holes.

[0036] Compared with the prior art, the present invention has the following advantages:

[0037] The portable emergency ECG monitor of the present invention is connected with a box seat on the monitor body, and an adjustment seat which can be adjusted by a driving member is arranged in the box seat, so that the adjustment seat drives the suction cup to move to the side away from the top plate of the box seat. When the ECG monitor is placed on a carrier with a flat and smooth surface such as a bedside table, the suction cup is adsorbed on the surface of the carrier, thereby improving the stability of the ECG monitor in a bumpy environment; when the suction cup is separated from the carrier, the ECG monitor is easy to move and portable.

[0038] By setting the driving part as a sleeve, a rotating rod and a bevel gear set, and arranging grooves and protrusions on the circumference of the adjusting seat, the rotating rod can be rotated, and the sleeve can be rotated under the transmission action of the bevel gear set; since the sleeve is threadedly connected to the adjusting seat, and under the limiting action of the protrusion and the groove, the adjusting seat can slide up and down along the center line of its length direction, thereby realizing the suction cup approaching or moving away from the carrier, and the whole process only requires rotating the rotating rod, which has the effect of being convenient for staff to use.

[0039] A hand wheel is connected to one end of the rotating rod outside the box seat, so that a worker can easily turn the rotating rod.

[0040] By setting a connecting pipe to realize the rotational connection between the sleeve and the box seat, setting the adjustment seat to be hollow, and setting the connection of the suction cup to be tubular and connected to the suction cup cup, an air guide pipe and an exhaust assembly are set. On the basis of ensuring that the driving part adjusts the relative distance between the suction cup and the carrier, the gas in the adjustment seat is exhausted, so that the adjustment seat is in a negative pressure state, thereby making the suction cup more firmly adsorbed on the carrier, thereby improving the stability of the fixation of the electrocardiogram monitor.

[0041] By setting the exhaust assembly including the exhaust cylinder, the sealing plug, the push-pull plate and the push-pull rod, when the negative pressure is drawn to the cavity of the adjustment seat, the push-pull rod is pulled to increase the volume of the exhaust cavity. When the volume of the cavity of the adjustment seat remains unchanged and the amount of air is constant, the volume of the exhaust cavity increases, thereby reducing the air pressure in the space formed by the adjustment seat, the exhaust cavity and the air guide tube, so that the suction cup is fixed on the carrier in the form of negative pressure. When the ECG monitor needs to be removed, just push the push-pull rod.

[0042] On the basis of setting the exhaust assembly, by setting the transmission part, it is possible to rotate the rotating rod to make the suction cup adsorbed on the carrier while pumping negative pressure into the cavity formed by the adjustment seat and the suction cup; the two are carried out synchronously only by rotating the rotating rod, which has the effect of facilitating the operation of the staff. Specifically, when the rotating rod is rotated, the rotation of the rotating rod drives the screw to rotate under the rotation of the flat gear set, and under the limit of the exhaust cylinder, the sliding seat drives the push-pull rod to slide in the exhaust cylinder, thereby adjusting the air pressure in the cavity formed by the adjustment seat and the suction cup.

[0043] By opening heat dissipation holes in the box seat, the electrocardiogram monitor body can dissipate heat, and negative pressure on the box seat can be avoided when the push-pull rod is pushed to compress the volume of the extraction cavity, thereby improving the smoothness of the push-pull rod when it is pushed and pulled.

[0070] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0071] The present embodiment relates to a portable emergency ECG monitor, which is convenient for fixing the ECG monitor on a carrier to improve the stability of the ECG monitor during use.

[0072] In terms of overall structure, Figures 1 to 6 As shown, the portable emergency ECG monitor comprises: a monitor body 1, a box seat 2, an adjustment seat 3, a suction cup 4 and a driving member 5; the box seat 2 is hollow inside, and the box seat 2 is fixedly connected to and carries the monitor body 1; the adjustment seat 3 is cylindrical, the box seat 2 vertically penetrates the bottom plate of the box seat 2 and can be slidably inserted into the box seat 2; the suction cup 4 is made of rubber, the connecting head 401 of the suction cup 4 is fixedly connected to the adjustment seat 3, and the suction cup cup 401 of the suction cup 4 is located on the side of the adjustment seat 3 away from the top plate of the box seat 2; the driving member 5 is connected to the adjustment seat 3, so that the adjustment seat 3 pushes the suction cup 4 to slide to the side away from the box seat 2.

[0073] By connecting the box seat 2 to the monitor body 1 and arranging an adjustment seat 3 that can be adjusted by a driving member 5 in the box seat 2, the adjustment seat 3 drives the suction cup 4 to move to the side away from the top plate of the box seat 2. When the ECG monitor is placed on a carrier with a flat and smooth surface such as a bedside table, the suction cup 4 is adsorbed on the surface of the carrier, thereby improving the stability of the ECG monitor in a bumpy environment; when the suction cup 4 is separated from the carrier, it is convenient to move the ECG monitor and make it portable.

[0074] Based on the overall introduction above, in this embodiment, the box seat 2 is fixedly connected to the bottom of the monitor body 1. The box seat 2 is rectangular as a whole, and legs are fixedly connected to the four corners of the bottom plate of the box seat 2. The legs separate the box seat 2 from the carrier and allow the suction cup 4 to be separated from the carrier, so that the ECG monitor has the characteristics of portability when the suction cup 4 is not used for fixing.

[0075] Based on the purpose of using the driving member 5 to adjust the distance between the suction cup 4 and the carrier, as Figures 2 to 3As shown, as an implementable method, the driving member 5 includes: a sleeve 501, a rotating rod 502 and a bevel gear set 503; the sleeve 501 is sleeved on the top of the adjustment seat 3 and is threadedly connected to the outside of the adjustment seat 3; and the sleeve 501 is rotatably connected to the top plate of the box seat 2; the rotating rod 502 is inserted into the box seat 2 from one side of the box seat 2 and extends to the sleeve 501; the bevel gear set 503 includes a first bevel gear 5031 sleeved outside the sleeve 501 and a second bevel gear 5032 sleeved outside the rotating rod 502; the first bevel gear 5031 meshes with the second bevel gear 5032. A groove 301 is formed on the circumferential outer wall of the adjustment seat 3 along the axial direction; a convex block 201 inserted into the groove 301 is formed on the bottom plate of the box seat 2.

[0076] By setting the driving member 5 to be a sleeve 501, a rotating rod 502 and a bevel gear set 503, and arranging the groove 301 and the protrusion 201 on the circumference of the adjustment seat 3, when the rotating rod 502 is rotated, the sleeve 501 is rotated under the transmission action of the bevel gear set 503; because the sleeve 501 is threadedly connected with the adjustment seat 3, and under the limiting action of the protrusion 201 and the groove 301, the adjustment seat 3 is slid up and down along the center line of its length direction, thereby realizing the suction cup 4 to approach or move away from the carrier, and the whole process only needs to rotate the rotating rod 502, which has the effect of being convenient for the staff to use. In order to facilitate the staff to rotate the rotating rod 502, a hand wheel 6 is connected to the end of the rotating rod 502 located outside the box seat 2.

[0077] In order to further improve the stability of the ECG monitor when the suction cup 4 is adsorbed on the carrier, Figures 3 to 6 As shown, the sleeve 501 is a tubular structure with a closed top, and a connecting pipe 5011 is arranged between the sleeve 501 and the top plate of the box seat 2, and the connecting pipe 5011 is fixedly connected to the box seat 2 and penetrates the sleeve 501 and is rotatably connected to the sleeve 501; the adjusting seat 3 is hollow inside; the connecting head 401 of the suction cup 4 is a tubular structure, one end of the connecting head 401 of the suction cup 4 penetrates the suction cup cup 401 of the suction cup 4, and the other end of the connecting head 401 of the suction cup 4 is connected to the cavity of the adjusting seat 3. An air guide pipe 7 is arranged at the connecting pipe 5011, one end of the air guide pipe 7 penetrates the side wall of the connecting pipe 5011 and is inserted into the sleeve 501 by the connecting pipe 5011 to communicate with the cavity of the adjusting seat 3; and an exhaust assembly 8 is arranged, and the exhaust assembly 8 is connected to the other end of the air guide pipe 7 to adjust the air pressure in the adjusting seat 3.

[0078] By setting a connecting tube 5011 to realize the rotational connection between the sleeve 501 and the box seat 2, setting the adjustment seat 3 to be hollow, and setting the connection of the suction cup 4 to be tubular and connected to the suction cup cup 401, on this basis, an air guide tube 7 and an exhaust assembly 8 are set. On the basis of ensuring that the driving member 5 adjusts the relative distance between the suction cup 4 and the carrier, the gas in the adjustment seat 3 is exhausted, so that the adjustment seat 3 is in a negative pressure state, thereby making the suction cup 4 more firmly adsorbed on the carrier, thereby improving the stability of the fixation of the electrocardiogram monitor.

[0079] Based on the purpose of adjusting the air pressure in the cavity formed between the adjusting seat 3, the suction cup 4 and the carrier, as Figures 4 to 5 As shown, as an implementable manner, the exhaust assembly 8 includes: an exhaust tube 801, a sealing plug 802, a push-pull plate 803 and a push-pull rod 804; the exhaust tube 801 is a cylindrical structure with one end closed, and is fixedly connected to the box base 2; the sealing plug 802 is located in the exhaust tube 801 and presses against the inner wall of the exhaust tube 801 to form an exhaust cavity 8a; the push-pull plate 803 is fixedly connected to the sealing plug 802; the push-pull rod 804 connects the push-pull plate 803 to enable the sealing plug 802 to slide in the exhaust tube 801 to adjust the size of the exhaust cavity 8a.

[0080] By setting the exhaust assembly 8 including the exhaust cylinder 801, the sealing plug 802, the push-pull plate 803 and the push-pull rod 804, when the negative pressure is extracted from the cavity of the adjustment seat 3, the push-pull rod 804 is pulled to increase the volume of the exhaust cavity 8a. When the volume of the cavity of the adjustment seat 3 remains unchanged and the amount of air is constant, the volume of the exhaust cavity 8a increases, thereby reducing the air pressure in the space formed by the adjustment seat 3, the exhaust cavity 8a and the air guide tube 7, so that the suction cup 4 is fixed on the carrier in the form of negative pressure. When the ECG monitor needs to be removed, just push the push-pull rod 804.

[0081] In order to further facilitate the operation of staff, such as Figures 3 to 5 As shown, the push-pull rod 804 is parallel to the rotating rod 502; a transmission member 9 is arranged between the push-pull rod 804 and the rotating rod 502, and the transmission member 9 includes: a screw rod 901, a slide 902 and a flat gear set 903; the screw rod 901 is parallel to the rotating rod 502, and the screw rod 901 is rotatably connected to the box seat 2; the slide 902 screw rod 901 passes through the slide 902 and is threadedly connected to the slide 902, and the slide 902 is fixedly connected to the push-pull rod 804; the flat gear set 903 includes a first flat gear 9031 mounted on one end of the screw rod 901 and a second flat gear 9032 mounted on the rotating rod 502, and the first flat gear 9031 and the second flat gear 9032 are meshed.

[0082] On the basis of setting the exhaust assembly 8, by setting the transmission member 9, it is realized that the rotating rod 502 is rotated to make the suction cup 4 adsorbed on the carrier, and the negative pressure is pumped into the cavity formed by the adjustment seat 3 and the suction cup 4; the two are synchronously performed only by rotating the rotating rod 502, which has the effect of facilitating the operation of the staff. Specifically, when the rotating rod 502 is rotated, under the rotation of the flat gear set 903, the rotating rod 502 rotates to drive the screw rod 901 to rotate, and under the limit of the exhaust cylinder 801, the sliding seat 902 drives the push-pull rod 804 to slide in the exhaust cylinder 801, thereby adjusting the air pressure in the cavity formed by the adjustment seat 3 and the suction cup 4.

[0083] In order to facilitate the heat dissipation of the monitor body 1, Figure 2 and Figure 5As shown, the box seat 2 is provided with heat dissipation holes 202, and the heat dissipation holes 202 penetrate the top plate and the bottom plate of the box seat 2. By providing the heat dissipation holes 202 in the box seat 2, it is convenient for the electrocardiograph monitor body 1 to dissipate heat, and it is avoided that the box seat 2 is subjected to negative pressure when the push-pull rod 804 is pushed to compress the volume of the pumping chamber 8a, thereby improving the smoothness of the push-pull rod 804 when being pushed and pulled.

[0084] When fixing the portable emergency ECG monitor described in the present application, the rotating rod 502 is rotated. Under the transmission action of the bevel gear set 503 and the limiting action of the protrusion 201, the rotating rod 502 drives the adjustment seat 3 and the suction cup 4 to move to the side close to the carrier, discharges the gas between the suction cup 4 and the carrier, and realizes the suction cup 4 adsorbed on the carrier under the action of atmospheric pressure; while rotating the rotating rod 502, under the action of the flat gear set 903, the screw 901 and the sliding seat 902, the push-pull rod 804 is pulled to increase the volume of the extraction chamber 8a, thereby making the suction cup 4, the cavity of the adjustment seat 3 and the space formed by the carrier in a negative pressure state, so that the suction cup 4 is more firmly adsorbed on the carrier; the stability of the ECG monitor during use is improved. When the ECG monitor needs to be removed from the carrier, the rotating rod 502 can be rotated in the opposite direction, making the ECG monitor more portable.

[0085] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
