[0028] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments.

[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] like Figures 1 to 3 The chest and abdominal cavity combined compression device shown in the figure includes a cardiopulmonary resuscitation machine 100 and a set of abdominal lifting and pressing mechanisms 400. Specifically, the cardiopulmonary resuscitation machine used in this scheme is a LUCAS cardiopulmonary resuscitation machine commonly used in the field of emergency treatment. The cardiopulmonary resuscitation machine mainly includes a support leg, a main unit installed on the support leg and performing regular chest compression on the patient, and a back plate connected to both ends of the support leg.

[0032] The abdominal lifting and compression mechanism 200 includes a C-shaped abdominal compression leg 410, and an abdominal compression back plate 480 is detachably connected to both ends of the abdominal compression leg to ensure the stability of the abdominal lifting and compression mechanism fixed on the patient's body when the patient is subjected to abdominal lifting. At the same time, an electric telescopic cylinder 420 is also installed on the upper part of the abdominal compression leg. After the telescopic rod of the electric telescopic cylinder passes downward through the abdominal compression leg 410, an adjustment rod 440 is coaxially inserted in the middle. It should be noted that a tightening nut is also screwed on the telescopic rod so that the extension length of the adjustment rod can be locked by the tightening nut after the adjustment is completed. In addition, an elliptical pressing plate 450 is also connected to the lower end of the adjusting rod, and the long axis of the elliptical pressing plate extends along the width direction of the patient's abdomen. At the same time, an air cushion 460 is installed on the lower surface of the pressing plate. The air cushion is filled with a pressure gas with a pressure value of about 30 to 50 kg to ensure that the air cushion state is stable when the abdominal pressure is lifted, and to produce a better buffering effect when the patient is under too much pressure. In addition, in order to enhance the lifting effect on the abdomen, a negative pressure pump 430 is fixedly installed on the electric telescopic cylinder 420, and a number of airways 470 are opened on the air cushion 460, which are connected from top to bottom. These airways are arranged in parallel along the elliptical contour of the air cushion. These airways 470 are connected to the negative pressure pump through a pressure hose. When the abdomen is lifted, the negative pressure pump puts the airway in a negative pressure state, so that the air cushion can be firmly adsorbed on the patient's abdomen. It should also be noted that the electric telescopic cylinder and the negative pressure pump in this scheme can be connected to an external power supply through a wire, or can obtain energy through a battery 490 plugged into the electric telescopic cylinder. Specifically, the battery is electrically connected to the electric telescopic cylinder and the negative pressure pump.

[0033] In order to achieve effective linkage between the cardiopulmonary resuscitation machine 100 and the abdominal lifting and pressing mechanism 400, as shown in FIG. Figures 1 to 3 As shown, it also includes a connection structure 200 that detachably connects the cardiopulmonary resuscitation machine 100 and the abdominal lifting and pressing mechanism 400, and a control mechanism 300 that controls the cardiopulmonary resuscitation machine 100 and the abdominal lifting and pressing mechanism 400 to perform alternate compression on the patient's chest and abdomen.

[0034] Specifically, the connecting mechanism 200 includes a ring 210 that is slidably mounted on the main unit of the cardiopulmonary resuscitation machine 100. A claw plate 220 is symmetrically arranged on both sides of the ring. The claw plate can be made of elastically bendable materials such as rubber and plastic. The free end of the claw plate has a C-shaped claw hook. When the ring is mounted in place, the claw hook of the claw plate extends into the hole on the leg of the cardiopulmonary resuscitation machine. It should be noted that in order to facilitate the fixation of the claw plate on the leg, the free end of the claw plate is arranged beyond the edge of the hole so that the claw hook can easily enter the hole. When the claw hook needs to be hooked on the edge of the hole, it is only necessary to pull the middle part of the claw plate outward to make the middle part of the claw plate arch and bend. Specifically, a bolt 230 is screwed on the claw plate, and a rotating shaft 240 is coaxially inserted on the inner end of the bolt facing the support leg. The rotating shaft is rotatably connected to the bolt, and a friction pad 250 is fixedly connected to the end of the rotating shaft. The friction pad abuts against the surface of the support leg with friction. When the claw plate needs to be hooked on the edge of the hole, the bolt is turned to make the claw plate bend outward in an arc, thereby shortening the distance between the two ends of the claw plate, so that the claw hook of the claw plate is hooked on the edge of the hole of the support leg, and the ring is fixed to the host of the cardiopulmonary resuscitation machine. In addition, if Figure 1 As described above, two telescopic rods 260 are fixedly connected to the collar, and one end of the two telescopic rods away from the collar is fixedly connected to the electric telescopic cylinder of the abdomen lifting and pressing mechanism 400.

[0035] The control mechanism 300 includes a controller 310 and a detector 330 for capturing the pressing action of the pressing head of the cardiopulmonary resuscitation machine and converting the captured action into a counting signal to be sent to the detector 330 which is electrically connected to the controller.

[0036] Specifically, the controller is also electrically connected to the electric telescopic cylinder 420 in the abdominal lifting and pressing mechanism 400. When the counting signal sent by the detector is accumulated in the controller, the controller sends a driving signal to the electric telescopic cylinder electrically connected thereto when the count signal is accumulated to the set threshold value. The electric telescopic cylinder performs the abdominal lifting and pressing action after a delay. Specifically, taking the compression mode of the LUCAS cardiopulmonary resuscitation instrument as an example, the number of compressions per minute is 120 times, and the time required for the compression head to rise and fall once is 0.5s. In order to stagger the compression action on the patient's abdomen with the compression action of the cardiopulmonary resuscitation machine, the electric telescopic cylinder delays 0.25s to press the patient's abdomen after receiving the signal sent by the controller, that is, when the compression head in the cardiopulmonary resuscitation machine retracts, the electric telescopic cylinder in the abdominal lifting and pressing mechanism extends to achieve combined staggered compression of chest and abdomen compression.

[0037] It should be noted that, in this solution, the detector captures and detects the descending action of the pressing head of the cardiopulmonary resuscitation machine through the following structure. Specifically, the detector 330 includes a lifting rod 331 fixedly connected to the collar 210, the lifting rod is vertically arranged and can adjust the length, and a toggle plate 332 with a downward flipping tendency is elastically hinged at the lower end of the lifting rod, and the free end of the toggle plate is horizontally abutted against the upper surface of the pressing head of the cardiopulmonary resuscitation machine. To ensure that the free end of the toggle plate can follow the downward flipping when the pressing head descends. A counting switch 333 is also arranged on the lower end of the lifting rod, and the counting switch is electrically connected to the controller. At the same time, the end of the toggle plate close to the lifting rod presses on the counting switch, and when the toggle switch flips down with the descending pressing head, it is separated from the contact with the counting switch, so that the counting switch loses pressure. It should be noted that in this solution, the counting switch adopts a trigger counting method, that is, when the counting switch loses the pressure from the toggle plate, its own trigger button pops up automatically and sends a counting signal to the controller.

[0038] In addition, it should be noted that in the present embodiment, the lifting and pressing frequency of the abdominal lifting and pressing mechanism is adjustable. Specifically, the lifting and pressing frequency of the abdominal lifting and pressing mechanism 400 for the abdominal cavity and the compression frequency of the cardiopulmonary resuscitation machine for the chest cavity can be in multiple ratios such as 1:1, 1:2 or 1:3. That is, if the compression frequency of the cardiopulmonary resuscitation machine is 120 times / minute, the compression frequency of the abdominal lifting and pressing mechanism can be 120 times / minute, 60 times / minute or 40 times / minute, etc. In order to facilitate rapid switching during first aid, at least one proportional switch 320 is also electrically connected to the controller 310. The proportional switch corresponds to the proportional threshold preset in the controller, and the proportional switch is used to achieve rapid switching of the proportional threshold in the controller.

[0039] Working principle: When it is necessary to perform combined chest and abdominal compression on the patient, first place the cardiopulmonary resuscitation machine on the patient's chest cavity, then pull down the compression head and gently touch the patient's chest according to the operating requirements of the cardiopulmonary resuscitation machine. Subsequently, the back plate lining in the abdominal lifting and pressing mechanism is set at the patient's waist and back, and then the sleeve is set on the host of the cardiopulmonary resuscitation machine. When the sleeve is set in place, the two claw hooks of the claw plate are respectively extended into the two holes of the cardiopulmonary resuscitation machine's legs. At this time, the medical staff presses the free end of the claw plate, and then turns the bolt to make the claw plate bend and arch, and the distance between the two ends of the claw plate is shortened, so that the claw hook of the claw plate is firmly hooked on the edge of the leg hole, and the sleeve is quickly fixed. At this time, the abdominal lifting and pressing mechanism connected to the other end of the telescopic rod also realizes relative connection with the cardiopulmonary resuscitation machine. At this time, the length of the telescopic rod is adjusted according to the patient's physical signs so that the pressure plate of the abdominal lifting and pressing mechanism is facing the patient's abdomen. When the above adjustment is completed, the abdominal compression back plate is connected to the abdominal compression leg. Then, pull down the lifting rod so that the toggle plate can be horizontally abutted against the compression head of the cardiopulmonary resuscitation machine. At this time, as the compression head descends and applies pressure, the toggle plate will also turn down. As the toggle plate turns down, the counting switch pressed by it will immediately lose the pressure from the toggle plate and pop out to activate. After the counting switch is activated, the controller electrically connected to it sends a counting signal, which is accumulated in the controller. When the value reaches the threshold, the controller drives the electric telescopic cylinder connected to it to extend after a delay of 0.25s and applies abdominal lifting pressure to the patient that is staggered with chest compression. It should be noted that the abdominal lifting mechanism in this scheme also needs to be adjusted accordingly before work. Specifically, when the abdominal pressure leg is connected to the abdominal pressure back plate, the medical staff loosens the tensioning nut on the telescopic rod, and then pulls down the adjusting rod so that the air cushion at the lower end of the adjusting rod presses against the patient's abdominal cavity. Then re-tighten the tensioning nut. At the same time, the medical staff synchronously starts the negative pressure pump so that the air cushion can be adsorbed on the patient's abdomen through negative pressure. Then when the abdomen lifting and pressing mechanism moves up and down, the abdomen will be lifted and pressed regularly.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
