Description

Technical Field

[0001] The utility model relates to a manual cardiopulmonary resuscitator, in particular to a manual cardiopulmonary resuscitator capable of controlling the pressing depth, belonging to the technical field of medical equipment. Background Art

[0002] Cardiopulmonary resuscitation is an emergency medical measure to maintain blood circulation and oxygen supply through artificial means during the first aid process of cardiac arrest or respiratory arrest. In the case of cardiac arrest or respiratory arrest, cardiopulmonary resuscitation can provide critical life support and extend the patient's first aid window before waiting for professional medical personnel to arrive.

[0003] The normal CPR process requires finding the correct position at the lower edge of the patient's sternum (heart position), crossing the fists, and placing the other hand on top. The first aid personnel use the weight of the upper body to press, and press 5-6 cm deep, with a compression frequency of about 100-120 times per minute.

[0004] However, for those who have not received professional training, it is difficult to ensure that the compression depth and frequency meet the corresponding requirements when performing cardiopulmonary resuscitation, which will cause the following problems: If the compression is too shallow, the heart may not be fully compressed, and thus insufficient blood flow may not be generated to various parts of the body, which will reduce the delivery of oxygen and nutrients and increase the risk of cellular hypoxia and damage; and insufficient compression will lead to insufficient perfusion pressure, affecting blood supply to important organs such as the brain; compression depth that is too shallow will also reduce the effect of each compression, thereby reducing stimulation to the heart, which may make it difficult for the heart to resume normal beating and affect the patient's survival rate in emergency treatment.

[0005] However, the pressing depth should not exceed 6 cm. If the pressing depth is too deep, it may easily cause fractures of the sternum and ribs, and then cause pneumothorax, which is extremely unfavorable for the patient's subsequent treatment. And if the pressing depth is too deep, the blood return to the heart will not be good, which will also have an adverse effect on the rescue effect.

[0006] Therefore, compression depth is one of the important factors affecting the success of CPR. When performing CPR, it is crucial to ensure that the compression depth reaches the standard. For non-professionals, it is very likely that the rescue will be ineffective if they cannot master the correct compression depth and frequency.

[0007] In addition, conventional first aid regulations require the rescuer to cross his hands and place them on the patient's chest, with the fingers pressing against each other, which will cause severe discomfort to the rescuer. In actual compression training, if the fingers of both hands are crossed and placed on the patient's chest for more than half a minute, the pain will gradually intensify, and when it lasts for two minutes, it is already unbearable. Even for professionals, after a short period of rescue, it is difficult to continue to maintain the correct compression frequency and depth due to lack of physical strength and severe knee discomfort and finger pain caused by kneeling compression. Summary of the invention

[0008] The utility model aims to provide a manual cardiopulmonary resuscitator with controllable compression depth, which has small size and light weight, can ensure compression depth, and can be applied in various first aid places.

[0009] To achieve the above purpose, the technical solution adopted by the utility model is: a manual cardiopulmonary resuscitator with controllable pressing depth, comprising a pressing device body, a strap, a support rod and a back plate, the pressing device body comprising a bottom plate and a pressing rod, the bottom plate is provided with a through hole, a pressing rod is inserted into the through hole, and a pressing head is provided at the bottom of the pressing rod; a left support rod and a right support rod are respectively provided at both ends of the bottom plate, the top ends of the left support rod and the right support rod are respectively detachably connected to the left end and the right end of the bottom plate, and the left support rod and the right support rod are respectively detachably connected to the left end and the right end of the bottom plate. The bottom ends are respectively supported on the left and right ends of the back plate; the left and right ends of the bottom plate are also connected with a left strap and a right strap respectively, the upper ends of the left strap and the right strap are detachably connected to the left and right ends of the bottom plate respectively, and the bottom ends of the left strap and the right strap are detachably connected to the back plate respectively; further, the length of the pressing rod is between 50-60mm, and the diameter of the pressing rod is between 10-100mm; further, a plurality of parallel card slots are provided at both ends of the back plate, and the bottom ends of the left support rod and the right support rod are clamped in The back panel is foldable, and one or more hinges are arranged on the back panel, and the back panel can be folded and stored along the hinges; further, Velcro is arranged on the side of the strap, and the length of the strap can be adjusted by adjusting the position of the Velcro adhesion; further, the support rod comprises a left support rod and a right support rod, and the lengths of the left support rod and the right support rod can be adjusted; further, the support rod comprises an upper support rod, a lower support rod and a sleeve, and the upper support rod, the sleeve and the lower support rod are connected in sequence from top to bottom, and the lower end of the upper support rod and the upper end of the lower support rod are provided with external threads, and the internal upper and lower ends of the sleeve are respectively provided with internal threads that match the threads of the upper support rod and the lower support rod, and the threads at the upper and lower ends of the sleeve are opposite, and the length of the support rod can be adjusted by rotating the sleeve; further, a suction cup is arranged at the bottom of the pressing head, and the diameter of the suction cup is between 5cm and 12cm; further, a detachable locking ring is arranged on the pressing rod, and the diameter of the locking ring is larger than the diameter of the through hole on the bottom plate.

[0010] The positive and beneficial technical effects of the utility model are:

[0011] 1. The utility model is provided with a pressing rod and a bottom plate supported by a supporting rod, and the bottom plate is flush with the patient's chest cavity, so that the pressing depth each time can be consistent with the height of the pressing rod, and the pressing depth each time can reach the standard, thereby ensuring the pressing effect;

[0012] 2. The adjustable rod length can adapt to the chest height of different patients. By setting multiple parallel slots at both ends of the back plate, the bottom ends of the left and right rods are clamped in the slots. It is also possible to simply adjust the inclination of the left and right rods to adjust the height of the bottom plate of the presser to adapt to different chest heights of the human body;

[0013] 3. Traditional manual pressing requires kneeling on the ground, and if the pressing time is too long, the knees will be worn out. The utility model can use both kneeling pressing and bending over pressing, and is no longer limited to kneeling pressing. Bending over pressing, compared with kneeling pressing, relies on the weight of the body, which can not only avoid kneeling wear, but also save effort, and can last longer than manual pressing;

[0014] 4. The utility model allows the rescuer to lay his hands flat and stack them, which fundamentally eliminates the pain and severe discomfort caused by finger squeezing. From the results of multiple first aid training, few people can continue for two minutes using the traditional pressing first aid posture. A considerable number of trainees are unable to persist not because of physical exhaustion, but because of unbearable pain in the knees and finger squeezing, which ultimately leads to the inability to continue first aid training;

[0015] 5. The utility model provides a strap to bind the chest and ribs during first aid compression, which can prevent fractures caused by rib expansion during compression, and provide rebound force during chest rebound to improve the chest rebound rate. The strap binding the chest can increase blood perfusion pressure during compression and improve the success rate of rescue;

[0016] 6. The suction cup on the compression head can be used to suck the chest of the rescued person during compression to help the patient's chest rebound;

[0017] 7. A detachable locking ring is provided on the pressing rod. After installing the locking ring, the pressing depth can be adjusted to meet the first aid needs in different occasions. BRIEF DESCRIPTION OF THE DRAWINGS

The pressing device body includes a bottom plate 8 and a pressing rod 2. A pressing handle 1 is provided on the top of the pressing rod, and a hand strap 4 is provided on the pressing handle. A through hole is provided on the bottom plate, and the pressing rod is inserted into the through hole. A pressing head is provided at the bottom of the pressing rod, and a suction cup 9 is provided on the pressing head. A support rod 5 is provided on the bottom plate. The function of the support rod is to maintain the horizontal position of the pressing device to prevent the pressing device from sinking during the pressing process. A left support rod and a right support rod are provided at both ends of the bottom plate. The left support rod and the right support rod are provided at the bottom ends of the bottom plate. The top end of the left and right ends of the bottom plate are detachably connected to the left and right ends of the bottom plate. In this embodiment, a number of parallel slots are provided at both ends of the back plate, and the bottom ends of the left support rod and the right support rod are clamped in the slots. The left and right support rods are clamped in different slots to adjust the horizontal height of the presser body to adapt to different patient chest heights; the left and right ends of the bottom plate are also connected to the left and right ends of the bottom plate, respectively, and the upper ends of the left and right straps are detachably connected to the left and right ends of the bottom plate, respectively, and the bottom ends of the left and right straps are also detachably connected to the back plate, respectively. In this embodiment, a hook is provided on the bottom plate, and a hanging ring provided on the strap cooperates with the hook.

[0023] According to the requirements of cardiopulmonary resuscitation, the pressing depth for adults is required to be 50mm-60mm. Therefore, the length of the pressing rod of the utility model is between 50-60mm. When pressing, the bottom plate remains in a horizontal position due to the support of the support rod. When the pressing rod is pressed down to the lowest position, the pressing depth is the length of the pressing rod, which will not exceed 60mm, which can prevent excessive pressing from causing harm to the human body. Figure 2 As shown, when the pressing depth for children needs to be 30-40 mm, a locking ring can be installed on the pressing rod, and the pressing rod is in place when the locking ring is pressed to the position.
