[0029] See also Figure 1 , Figure 2 and Figure 3A cardiopulmonary resuscitation machine 10 provided in an embodiment of the present application includes a housing 100, a pressing mechanism 200 and a detection mechanism 300. The pressing mechanism 200 includes a driver 210, a push rod 220 and a pressing head 230. The driver 210 is accommodated in the housing 100, the push rod 220 is slidably disposed in the housing 100, and the pressing head 230 is connected to the end of the push rod 220, so that the pressing head 230 can be located outside the housing 100. The driver 210 drives the push rod 220 to reciprocate along the height direction of the cardiopulmonary resuscitation machine 10, and the height direction can also be understood as a vertical direction, so that the push rod 220 drives the pressing head 230 to reciprocate up and down, so that the pressing head 230 presses the patient, thereby helping the patient to restore spontaneous breathing and spontaneous circulation to achieve cardiopulmonary resuscitation function. The detection mechanism 300 is disposed on the housing 100. The detection mechanism 300 may include at least one of a blood oxygen connector 310 and a carbon dioxide connector 320. For example, the detection mechanism 300 may include only the blood oxygen connector 310, or only the carbon dioxide connector 320, or at least the blood oxygen connector 310 and the carbon dioxide connector 320. The blood oxygen connector 310 is used to detect oxygen saturation, and the carbon dioxide connector 320 is used to detect carbon dioxide concentration.

[0030] In fact, after performing cardiopulmonary resuscitation through compression, it is usually necessary to test the patient's oxygen saturation and carbon dioxide concentration. The changes in oxygen saturation and carbon dioxide concentration can be used to determine whether the patient is in respiratory failure type 1 or respiratory failure type 2, that is, to effectively distinguish the severity of the patient's respiratory failure, so as to provide targeted oxygen therapy to the patient. Obviously, respiratory failure type 2 is more serious than respiratory failure type 1. During outdoor disaster rescue, the breathing and oxygen supply equipment carried by medical staff is limited. When medical staff know the severity of the patient's respiratory failure, they can give priority to the limited breathing and oxygen supply equipment for patients with more severe respiratory failure, thereby increasing the success rate of patient rescue.

[0031] If the cardiopulmonary resuscitation machine 10 adopts a design mode that does not include the detection mechanism 300, the cardiopulmonary resuscitation machine 10 only has a pressing function, but does not have the oxygen saturation and / or carbon dioxide concentration detection function, which leads to the single function of the cardiopulmonary resuscitation machine 10. In the case that the cardiopulmonary resuscitation machine 10 only has a pressing function, the detection of oxygen saturation and carbon dioxide concentration is performed by other special equipment. On the one hand, this will make the special detection equipment inconvenient to carry, especially in the field rescue process, it will consume the physical strength of medical staff, thereby affecting the rescue effect of medical staff. On the other hand, it will also increase the medical cost of rescuing patients.

[0032] As for the cardiopulmonary resuscitation machine 10 in the above embodiment, since the cardiopulmonary resuscitation machine 10 has a detection mechanism 300, the cardiopulmonary resuscitation machine 10 has both a pressing cardiopulmonary resuscitation function and a detection function for oxygen saturation and / or carbon dioxide concentration, thereby realizing the diversification of the functions of the cardiopulmonary resuscitation machine 10. When the cardiopulmonary resuscitation machine 10 has completed pressing, the oxygen saturation and / or carbon dioxide concentration can then be detected, so that medical staff can provide targeted oxygen therapy to the patient and improve the success rate of the patient's rescue. In addition, the cardiopulmonary resuscitation machine 10 integrates the pressing function and the detection function, which can save the need to carry other special detection equipment, thereby improving the convenience of carrying the cardiopulmonary resuscitation machine 10, and ultimately improving the rescue effect of medical staff on the patient. It can also reduce the medical cost of rescuing the patient.

[0033] See also Figure 1 In some embodiments, when the blood oxygen connector 310 and the carbon dioxide connector 320 exist at the same time, the blood oxygen connector 310 and the carbon dioxide connector 320 can be arranged at intervals on the housing 100. When it is necessary to detect the oxygen saturation, one end of the external blood oxygen probe can be matched with the blood oxygen connector 310, and the other end of the external blood oxygen probe can be in contact with a specific position of the patient to detect the oxygen saturation. Similarly, when it is necessary to detect the carbon dioxide concentration, one end of the external carbon dioxide probe can be matched with the carbon dioxide concentration connector, and the other end of the external carbon dioxide probe can be in contact with a specific position of the patient to detect the carbon dioxide concentration.

[0034] See also Figure 2 , Figure 3 and Figure 4 In some embodiments, the housing 100 includes an upper housing 110, a middle housing 120 and a lower housing 130, the middle housing 120 is fixed between the upper housing 110 and the lower housing 130, the lower housing 130 is detachably connected to the upper housing 110, the driver 210 is disposed in the upper housing 110, and a sliding hole 131 is provided on both the middle housing 120 and the lower housing 130, and the push rod 220 is slidably matched with the sliding hole 131. The lower housing 130 can be carried on the patient's body and directly contact the patient. The lower housing 130 and the upper housing 110 can be detachably connected by bolt connection. Of course, the lower housing 130 and the upper housing 110 can also be detachably connected by snap connection.

[0035] In some embodiments, the cardiopulmonary resuscitation machine 10 further includes a display screen 400, which is disposed on the top of the upper shell 110, that is, the display screen 400 is disposed on the end face of the upper shell 110 away from the lower shell 130. By providing the display screen 400, during the detection of oxygen saturation and carbon dioxide concentration, the value of oxygen saturation detected by the cooperation of the blood oxygen probe and the blood oxygen connector 310 can be presented through the display screen 400, so that medical staff can quickly know the specific situation of oxygen saturation; the value of carbon dioxide concentration detected by the cooperation of the carbon dioxide probe and the carbon dioxide concentration connector can also be presented through the display screen 400, so that medical staff can quickly know the specific situation of oxygen and carbon dioxide concentration. Therefore, the display screen 400 effectively forms the values ​​of oxygen saturation and carbon dioxide concentration so that medical staff can treat patients in a targeted manner based on them, thereby improving the success rate of rescue.

[0036] See also Figure 2 , Figure 3 and Figure 4 In some embodiments, the pressing mechanism 200 further includes a button 240, which can be disposed on the upper shell 110. The button 240 can be disposed on the upper shell 110 by sliding or rotating, and the button 240 is connected to the driver 210. When the user applies force to the button 240, the driver 210 can be activated, so that the driver 210 drives the push rod 220 to reciprocate up and down, and then the pressing head 230 follows the push rod 220 to reciprocate up and down to press the patient. The driver 210 can be a screw drive assembly, which is connected to the push rod 220 by a threaded connection. The screw drive assembly will perform a rotational motion, so that the rotational motion of the screw drive assembly relative to the housing 100 is converted into the sliding of the push rod 220 relative to the housing 100 in the vertical direction through the action of the thread pair, so that the pressing head 230 follows the push rod 220 to reciprocate up and down to press the patient.

[0037] In some embodiments, the cardiopulmonary resuscitation machine 10 further includes a hook 500, the number of which is two, and the two hooks 500 are arranged at opposite ends of the lower shell 130, and the hook 500 can be detachably connected to the lower shell 130. When the lower shell 130 is carried on the patient, the hook 500 can be bound to the patient through a strap so that the cardiopulmonary resuscitation machine 10 presses the patient. The hook 500 can include a bearing portion 510, a clamping portion 520 and a limiting portion 530. The bearing portion 510 can be directly carried on the patient. The bearing portion 510 is generally a rectangular parallelepiped structure, so that the bearing portion 510 has a side surface and a top surface, the side surface extends in a vertical direction and is vertically arranged, and the top surface extends in a horizontal direction and is horizontally arranged, so that the side surface and the top surface can be perpendicular to each other. The clamping portion 520 is protrudingly arranged on the side of the bearing portion 510, and a clamping hole 521 is opened on the clamping portion 520. The clamping portion 520 realizes a snap connection relationship with the lower shell 130 through the clamping hole 521. The limiting portion 530 is protrudingly disposed on the top surface of the bearing portion 510 , and the limiting portion 530 is curved, so that the limiting portion 530 encloses a limiting space 531 .

[0038] In the process of binding the cardiopulmonary resuscitation machine 10 with the binding strap, the binding strap can be accommodated in the limiting space 531, so that the limiting part 530 can well limit the binding strap in the horizontal direction and the vertical direction, thereby improving the stability and reliability of the binding strap to the cardiopulmonary resuscitation machine 10. It is prevented that the housing 100 and the entire cardiopulmonary resuscitation machine 10 will swing relatively much relative to the patient when the push rod 220 drives the pressing head 230 to move, thereby improving the pressing and cardiopulmonary resuscitation effect of the cardiopulmonary resuscitation machine 10 on the patient.

[0039] See also Figure 2 , Figure 3 and Figure 4 In some embodiments, the cardiopulmonary resuscitation machine 10 further includes a battery 600. The battery 600 can be disposed in the upper shell 110 of the housing 100. The battery 600 is electrically connected to the pressing mechanism 200 and the detection mechanism 300, so that the battery 600 provides energy to the pressing mechanism 200 and the detection mechanism 300. In this way, there is no need for an external power source to power the cardiopulmonary resuscitation machine 10 through a wire, so that the cardiopulmonary resuscitation machine 10 has its own power, which can facilitate the use of the cardiopulmonary resuscitation machine 10 in the field. The battery 600 can be a storage battery 600 that is repeatedly charged and discharged, so that the cardiopulmonary resuscitation machine 10 can be recycled for many times.

[0040] In summary, in view of the fact that the cardiopulmonary resuscitation machine 10 has a detection mechanism 300, it is ensured that the cardiopulmonary resuscitation machine 10 has both the cardiopulmonary resuscitation function of pressing and the function of detecting oxygen saturation and / or carbon dioxide concentration at the same time, thereby realizing the diversification of the functions of the cardiopulmonary resuscitation machine 10. When the cardiopulmonary resuscitation machine 10 has completed pressing, it can then detect the patient's oxygen saturation and / or carbon dioxide concentration, so that medical staff can provide targeted oxygen therapy to the patient and improve the patient's rescue success rate. In addition, the cardiopulmonary resuscitation machine 10 integrates the pressing function and the detection function into one, which can save the need to carry other special detection equipment, thereby improving the convenience of carrying the cardiopulmonary resuscitation machine 10, and ultimately improving the rescue effect of medical staff on the patient. It can also reduce the number of medical devices used during the rescue process, thereby reducing the medical cost of rescuing the patient.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application.
