Description

Technical Field

[0001] The utility model belongs to the technical field of medical emergency equipment, and in particular relates to a cardiopulmonary resuscitation machine with a tripod. Background Art

[0002] Cardiopulmonary resuscitation is an extremely important medical emergency skill. When a patient has no pulse, no breathing, or cardiac arrest, cardiopulmonary resuscitation should be performed immediately to save his life. The success rate of manual cardiopulmonary resuscitation in my country has long been less than 1%. The development and promotion of cardiopulmonary resuscitation equipment has become a hope for improving the success rate of resuscitation. At present, although there are many electric and pneumatic cardiopulmonary resuscitation machines, they are expensive and complicated to operate. In order to prevent the resuscitation machine from shaking and shifting, the patient's body needs to be held on the back plate of the resuscitation machine that is connected to the resuscitation machine on one side ("L" shape) or on both sides ("U" shape), such as the patent No. 2014204255077 of "Cardiopulmonary resuscitation machine with high-frequency ventilation function" and the patent No. 2017213896384 of "A cardiopulmonary resuscitation machine". Although such a setting can use the patient's own pressure to ensure the stability of the resuscitation machine, it requires one person to hold the patient's upper body and the other person to place the back plate of the resuscitation machine under the patient's back. After repeated adjustments by the two people, the back plate position can be adapted to the pressing position of the cardiopulmonary resuscitation machine. It is time-consuming and labor-intensive, and at least two people are required to cooperate in the operation, which seriously exceeds the golden 4-minute rescue time and is only suitable for use in hospitals. 70% of cardiac arrest patients mostly occur at home, because most of them are alone at home with a spouse or a nanny. Even if there is a resuscitation machine, one person cannot move the backboard to a position suitable for the resuscitation machine to press, and the precious rescue opportunity is missed. As a result, 540,000 people in my country die of sudden cardiac death each year, which has become a serious problem of pre-hospital medical emergency that seriously endangers people's lives and health and there is no effective treatment.

[0003] Therefore, developing a resuscitation machine that is low-priced, high-quality, simple and fast, suitable for widespread deployment in public places, affordable and usable by low- and middle-income families, which can ensure stable and accurate compression of the resuscitation machine and does not require moving the patient, and can be operated by one person, is of great practical significance for improving the success rate of resuscitation and saving the precious lives of thousands of patients with cardiac arrest. Summary of the invention

[0004] The utility model aims to provide a cardiopulmonary resuscitation machine with a tripod which meets the standard requirements of the International Cardiopulmonary Resuscitation Guidelines in view of the difficulties and problems of the existing cardiopulmonary resuscitation.

[0005] The purpose of the utility model is achieved as follows: it includes a pressing device and a tripod, and is characterized in that: the pressing device includes a push rod motor, a reciprocating controller, a timing controller and a regulating tube, and a pressing pad electrically connected in a chassis; the tripod includes a flange tube, a supporting foot rod, a regulating pull rod, a connecting ring sleeve and a pressure-stabilizing knee pad; the flange tube is fixedly connected to the bottom plate of the chassis, and the connecting ring sleeve is slidably sleeved on the flange tube, and a loose and tight gap is provided at the lower end of the flange tube, and a locking device is sleeved on the flange tube with the loose and tight gap; the upper end of the regulating tube passes through the motor push rod and is fixedly connected to the front end of the push rod motor, and the lower end of the regulating tube passes through the flange tube and cooperates with the locking device at the lower end of the flange tube, and the motor push rod passes through the regulating tube and is vertically fixedly connected to the pressing pad; a sliding card connector is fixedly connected to the push rod motor, and a guide rail slot is installed on the inner wall of the chassis.

[0007] Preferably, the supporting foot rod is an adjustable telescopic sleeve rod structure, on which a joint lock is provided.

[0008] Preferably, a rotatable folding pressure-stabilizing knee pad is respectively provided at the lower ends of the two front supporting foot rods, the front side of the pressure-stabilizing knee pad is made of a soft and thick material, and the back side of the pressure-stabilizing knee pad is made of a non-slip and wear-resistant material.

[0009] Preferably, the setting of the tension gap cooperates with the tension lock control of the locking device; the locking device is a quick-release pipe clamp or other locking devices in the prior art that can achieve tension control.

[0010] Preferably, the arrangement of the sliding card connector is adapted to the nested movement of the guide rail slot vertically installed on the inner wall of the chassis, and the sliding card connector cooperates with the up and down movement of the push rod motor.

[0011] Preferably, the pressing device also includes a power supply device and a control display screen.

[0012] Compared with the prior art, the utility model has the following technical effects:

[0013] 1. Easy and quick adjustment to ensure the golden 4-minute rescue time limit. The utility model only needs two simple actions, one opening and one closing, to quickly adjust the chest height and fix the zero point position of the compression pad. It only takes one or two minutes to perform standard compression, ensuring the golden 4-minute rescue time limit.

[0014] 2. Low price, high quality, and wide application. The utility model adopts a push rod motor as the pressing power, which can not only reduce the air source device and auxiliary equipment required by the pneumatic drive device, but also reduce the weight of the machine body.

It has the characteristics of low cost, precision, speed, and easy operation. It is suitable for wide deployment in public places, and low- and middle-income patient families can afford it and use it.

[0015] 3. The stabilizing device is novel and can be operated by one person. The stabilizing backboard of existing automatic cardiopulmonary resuscitation machines is mostly fixedly connected to the resuscitation machine. When in use, the patient's front half of the body must be lifted up and the stabilizing backboard must be placed under the patient. If one person is rescuing, the machine cannot be installed for timely rescue. The utility model adopts a tripod setting. It is only necessary to straddle the tripod on the patient, move the tripod rod appropriately, align the pressure pad with the chest pressure position, lock the chest height, and then rotate the stabilizing knee pad to the appropriate position. Kneel on the stabilizing knee pad with both knees, which not only limits the movement of the tripod rod, but also prevents damage to the knees by kneeling directly on the ground during artificial respiration, and also reduces the fatigue caused by kneeling and standing three times a minute. It is easy to use and can be operated by one person, which is conducive to improving the success rate of cardiopulmonary resuscitation. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] As attached Figure 1 The cardiopulmonary resuscitation machine with a tripod shown in the figure comprises a pressing device and a tripod, wherein the pressing device comprises a push rod motor 12, a reciprocating controller 13, a timing controller 14, a regulating tube 6, and a pressing pad 2 electrically connected in a chassis 1; the tripod comprises a flange tube 3, a supporting foot rod 8, a regulating pull rod 9, a connecting ring sleeve 10, and a pressure-stabilizing knee pad 11; the flange tube 3 is fixedly connected to the chassis bottom plate, the connecting ring sleeve 10 is slidably sleeved on the flange tube, and the method A tight gap 4 is provided at the lower end of the flange tube 3, and a locking device 5 is sleeved on the flange tube 3 with the tight gap; the upper end of the regulating tube 6 passes through the motor push rod 17 and is fixedly connected to the front end of the push rod motor 12, and the lower end of the regulating tube 6 passes through the flange tube 3 and cooperates with the locking device 5 at the lower end of the flange tube 3, and the motor push rod 17 passes through the regulating tube 6 and is vertically fixedly connected to the pressing pad 2; a sliding card connector 16 is fixedly connected to the push rod motor 12, and a guide rail slot 15 is installed on the inner wall of the chassis.

[0021] The upper ends of the three supporting foot rods 8 are articulated and movably connected to the upper end of the flange pipe 3 in the shape of two in front and one in the back; one end of the three regulating pull rods 9 is hingedly connected to the inner sides of the three supporting foot rods 8 respectively, and the other ends of the three regulating pull rods 9 are hingedly matched with the connecting ring sleeve 10 that slides with the outer wall of the flange pipe 3, and a tension adjustment bolt 7 is arranged on the connecting ring sleeve 10.

[0022] The setting of the adjusting bolt 7 can lock the position of the connecting ring sleeve 10 sliding up and down on the flange pipe 3 to determine the expansion and contraction degree of the tripod. The up and down movement of the regulating tube 6 can meet the needs of regulating the chest height of most patients.

[0023] The support foot bar 8 is an adjustable telescopic sleeve structure, on which a joint lock is arranged. The joint lock is arranged to adjust the lengthening and shortening of the support foot bar 8, so as to meet the needs of very few special patients who cannot adjust the chest height by moving the control tube 6 up and down.

[0024] The lower ends of the two front supporting legs 8 are respectively provided with rotating folding pressure-stabilizing knee pads 11, which are arranged to cooperate with the unfolding and folding of the tripod, and can be rotated left and right and folded up and down; when the tripod is opened, the two folded and leaning pressure-stabilizing knee pads 11 will be folded back and opened due to the action of gravity.

[0025] After the tripod is adjusted and placed, the ends of the two pressure-stabilizing knee pads 11 can be slightly moved for easy operation, and then the two knees can be kneeled on the knee pads to ensure the stability of the tripod; after the operation is completed, as the tripod is folded, the two pressure-stabilizing knee pads 11 are manually rotated and folded to form a folded upright shape. The stability of the tripod is strengthened by the rescuer's own weight pressure, and knee pain caused by kneeling directly for artificial respiration is avoided.

[0026] Rotatable foldable pressure-stabilizing knee pads 11 are respectively arranged at the lower ends of the two supporting foot rods 8 arranged in the front. The front side of the pressure-stabilizing knee pads 11 is made of soft and thick material, and the back side of the pressure-stabilizing knee pads 11 is made of anti-slip and wear-resistant material.

[0027] The setting of the tension gap 4 is coordinated with the tension lock control of the locking device 5; the locking device 5 is a quick-release tube clamp or other devices in the prior art that can achieve tension control. Only the quick-release tube clamp needs to be easily opened, and the positioning tube 6 together with the motor at the upper end and the pressing pad 2 at the end of the push rod can move up and down. When the pressing pad 2 just fits the patient's chest compression position, the quick-release tube clamp 5 is closed at will. The whole process only requires two simple actions of opening and closing, and the chest height can be quickly adjusted, the zero point position of the pressing pad 2 can be determined, and the correctness of the pressing position and the accuracy of the pressing amplitude can be ensured.

[0028] The slide card connector 16 is adapted to be nested and moved with the guide rail slot 15 vertically installed on the inner wall of the chassis, and the slide card connector 16 is matched with the up and down movement of the push rod motor 12. The arrangement of the guide rail slot 15 and the slide card connector 16 ensures that the push rod motor 12 moves vertically up and down in the box, meeting the needs of adjusting the chest height and determining the zero point position of the pressing pad 2.

[0029] The utility model is used in public places outside hospitals, especially in the families of cardiovascular and cerebrovascular patients, to perform cardiopulmonary resuscitation on cardiac arrest patients who have no heartbeat, no breathing and cannot move. Otherwise, it is unnecessary and worthless to use.

[0030] The utility model takes the requirements of the International Guidelines for Cardiopulmonary Resuscitation, namely, a compression amplitude of 5-6 cm, a compression frequency of 100-120 times per minute, and two artificial respirations for every 30 compressions, as the standard.
