Description

Technical field:

[0001] The utility model relates to the technical field of medical device products, in particular to a CPR operation auxiliary instrument. Background technology:

[0002] At present, due to the accelerated pace of life, high work / life pressure and the influence of living habits, the frequency of cardiac arrest has increased significantly. Cardiac arrest refers to the sudden termination of the heart's ejection function, the disappearance of the pulsation and heart sounds of the aorta, and the heart stops pumping blood. If it cannot be restored in time, the important organs, especially the head, will not receive timely blood and oxygen supply, resulting in brain death or other organ failure, which is difficult to recover. Effective cardiopulmonary resuscitation within the golden three minutes after cardiac arrest is the most effective way to treat cardiac arrest. However, even trained people will still find it difficult to perform effective cardiopulmonary resuscitation after a long time or in an emergency because they forget the essentials of the movements or the loss of muscle memory. The movements are difficult to standardize, so the success rate of cardiopulmonary resuscitation for ordinary people is still not high. Therefore, in emergency situations, there is a need for an auxiliary device to help the rescuer perform cardiopulmonary resuscitation operations. Effective guidance and auxiliary rescue can greatly improve the success rate of rescue. At the same time, doctors and nurses in medical schools and hospitals also need a convenient and intelligent auxiliary device to help with the training, experiments, assessment and emergency rescue of cardiopulmonary resuscitation operations in daily life.

[0003] Cardiopulmonary resuscitation (CPR), also known as cardiopulmonary resuscitation, is a life-saving technique for sudden cardiac and respiratory arrest, which is intended to restore the patient's spontaneous breathing and circulation.

[0004] The Chinese utility model patent with the patent number ZL201721341075.1 discloses a cardiopulmonary resuscitation auxiliary device, which includes a main body, an elastic member, a force gauge, a processor and a sound device. In order to ensure that the cardiopulmonary resuscitation auxiliary device can be firmly held by the user, a hand-held portion can be additionally provided on the upper side of the main body, as shown in the attached figure of the patent. Figure 3-4 As shown in the figure, the user can hold it with his fingers, so that when performing cardiopulmonary resuscitation, the cardiopulmonary resuscitation auxiliary device can be positioned at the appropriate position on the patient where downward pressure is to be applied. Figure 6 As shown in A-6B, the hand-held portion has other positions for inserting fingers, so that the user can hold the body firmly when performing chest compression procedures.

[0005] There are some problems with the above-mentioned cardiopulmonary resuscitation auxiliary device: since the cardiopulmonary resuscitation auxiliary device only has a hand-held part on the main body for two fingers to hold, however, during the continuous pressing process, two fingers are required to hold the hand-held part all the time, which will cause finger soreness and is very likely to cause deviation, resulting in failure to achieve accurate pressing and ensure the correct implementation of cardiopulmonary resuscitation; or, fingers other than the thumb can pass through the hand-held part, while the thumb is located outside the hand-held part. This method also cannot form a stable combination between the human hand and the hand-held part. At the same time, a large gap is easily formed between the human hand and the hand-held part, making it difficult to lift the entire cardiopulmonary resuscitation auxiliary device, affecting the correct implementation of cardiopulmonary resuscitation.

[0026] The utility model is further described below in conjunction with specific embodiments and drawings.

[0027] See Figure 1-7 As shown, a CPR operation auxiliary device is worn on the palm of a human body and is used to assist in routine cardiopulmonary resuscitation operation training, experiments, assessments, and emergency rescue.

[0028] The CPR operation auxiliary device of the utility model comprises a pressing plate 1, a main unit 2 arranged on both sides of the upper end of the pressing plate 1, and a wristband structure 300 used for restraining and positioning the palm. The wristband structure 300 is used to restrain and position the palm placed on the pressing plate 1 so that the pressing plate 1 is fixed to the lower end of the palm for cardiopulmonary resuscitation compression.

[0029] The wristband structure 300 includes a left silicone wristband 3 and a right silicone wristband 4 which are spaced apart at the upper end of the pressing plate 1 and are made of silicone, wherein the left silicone wristband 3 is located beside the host 2, that is, the wristband structure 300 in the utility model adopts a left silicone wristband 3 and a right silicone wristband 4 made of silicone, which can better restrain the palm, not only can the tightness of the restraint be increased, and the problem of adapting the palms of different sizes can be solved, but also the wrapping property is better, and it will not cause finger soreness, and can make the palm feel more comfortable. In addition, it can also ensure that the palm of the person applying force will not be offset from the pressing plate 1 when performing cardiopulmonary resuscitation, thereby ensuring the correct implementation of cardiopulmonary resuscitation. The lower ends of the left silicone wristband 3 and the right silicone wristband 4 are fixedly connected to the pressing plate 1, and the lower parts of the left silicone wristband 3 and the right silicone wristband 4 are respectively provided with a first through-hole 301 and a second through-hole 401 for the thumb to pass through, and the upper part of the left silicone wristband 3 serves as a bendable first free end 31, and the first free end 31 is provided with a first connecting member 310, and the upper part of the right silicone wristband 4 serves as a bendable second free end 41, and the second free end 41 is provided with a second connecting member 410. After the first free end 31 and the second free end 41 are bent and fitted with each other, they are fixedly connected by the first connecting member 310 and the second connecting member 410, so that a wearing and restraining space that can be tightly fitted to the palm is enclosed between the left silicone wristband 3 and the right silicone wristband 4 and the pressing plate 1, and when the first connecting member 310 and the second connecting member 410 are not connected, the first free end 31 and the second free end 41 are separated from each other by their own elastic force.

[0030] When the utility model is in use, the force-applying person can wear it with the left hand or the right hand, and no matter whether it is worn with the left or right hand, it can ensure that the host 2 is in a desired orientation, for example, always on the left or right side, so as to meet the usage requirements of different force-applying persons.

[0031] Specifically, when it is necessary to ensure that the host 2 is on the left, such as Figure 1 As shown, the force-applicator can wear it with his right hand, with the thumb of his right hand passing through the first through-hole 301 at the bottom of the left silicone wristband 3, and the palm of his right hand pressing on the upper end of the pressing plate 1, and then the first free end 31 at the top of the left silicone wristband 3 and the second free end 41 at the top of the right silicone wristband 4 are bent and fitted to each other, and fixedly connected by the first connecting member 310 and the second connecting member 410, so as to fix the right hand and the utility model together to complete the wearing; or, the force-applicator can wear it with his left hand, with the thumb of his left hand passing through the second through-hole 401 at the bottom of the right silicone wristband 4, and the palm of his left hand pressing on the upper end of the pressing plate 1, and then the first free end 31 at the top of the left silicone wristband 3 and the second free end 41 at the top of the right silicone wristband 4 are bent and fitted to each other, and fixedly connected by the first connecting member 310 and the second connecting member 410, so as to fix the left hand and the utility model together to complete the wearing; both of the above wearing methods can ensure that the host 2 is on the left side.

[0032] Of course, you can also ensure that host 2 is on the right side. Figure 1 The CPR operation assisting device shown is rotated 180°, and the person applying force can wear it with his left hand, with the thumb of his left hand passing through the first through-hole 301 at the bottom of the left silicone wristband 3, and the palm of his left hand pressing on the upper end of the pressing plate 1, and then the first free end 31 at the top of the left silicone wristband 3 and the second free end 41 at the top of the right silicone wristband 4 are bent and fitted to each other, and are fixedly connected by the first connecting member 310 and the second connecting member 410, so as to fix the left hand and the utility model together to complete the wearing; or, the person applying force can wear it with his right hand, with the thumb of his right hand passing through the second through-hole 401 at the bottom of the right silicone wristband 4, and the palm of his right hand pressing on the upper end of the pressing plate 1, and then the first free end 31 at the top of the left silicone wristband 3 and the second free end 41 at the top of the right silicone wristband 4 are bent and fitted to each other, and are fixedly connected by the first connecting member 310 and the second connecting member 410, so as to fix the right hand and the utility model together to complete the wearing; both of the above wearing methods can ensure that the host 2 is on the right side.

[0033] That is to say, the wristband structure 300 of the utility model is a left silicone wristband 3 and a right silicone wristband 4 made of silicone to bind the left palm or the right palm, and the binding effect of the palm is very ideal. It can not only increase the tightness of the binding, solve the problem of different people's palm adaptation, but also has better wrapping, will not cause finger soreness, and can make the palm feel more comfortable, to a certain extent can reduce fatigue, increase the number of times the force applicator presses, in addition, it can also ensure that the palm of the force applicator will not deviate from the pressing plate 1 when performing cardiopulmonary resuscitation, and ensure the correct implementation of cardiopulmonary resuscitation. In addition, the utility model can be worn on the left and right palms, and can also ensure that the host 2 is in the desired orientation, meet different usage requirements, and has strong market competitiveness.

[0034] In order to further improve the wrapping and comfort of wearing on the palm, the following improvements have been made: the lower part of the left silicone wristband 3 is formed with a first concave position 302 for accommodating the outer part of the base of the thumb or the hypothenar, and the first perforation 301 passes through the first concave position 302; the lower part of the right silicone wristband 4 is formed with a second concave position 402 for accommodating the outer part of the base of the thumb or the hypothenar, and the second perforation 401 passes through the second concave position 402. When wearing, when the thumb passes through the first perforation 301 of the left silicone wristband 3, the outer part of the base of the thumb fits in the first concave position 302, and the hypothenar of the palm fits in the second concave position 402, thereby ensuring that the entire palm can fit better with the wristband structure 300, with a smaller gap and better comfort. Alternatively, when the thumb passes through the second through-hole 401 of the right silicone wristband 4, the outer periphery of the base of the thumb fits in the second concave position 402, and at the same time, the hypothenar of the palm fits in the first concave position 302, thereby ensuring that the entire palm can fit better with the wristband structure 300, with a smaller gap and better comfort.

[0035] The left silicone wristband 3 and the right silicone wristband 4 are both integrally formed of gas phase silicone (with a hardness of 40 degrees).

[0036] The first connecting member 310 and the second connecting member 410 are Velcro or magnets. The details are as follows:

[0037] When the first connector 310 and the second connector 410 are Velcro, the first connector 310 is a Velcro loop surface, and the second connector 410 is a Velcro hook surface. When the first connector 310 and the second connector 410 are fitted, the Velcro loop surface and the Velcro hook surface are fitted and fixed. Of course, it can also be that: the first connector 310 is a Velcro hook surface, and the second connector 410 is a Velcro loop surface, which can be designed according to actual conditions. Among them, the Velcro loop surface and the Velcro hook surface can be fixedly connected to the first free end 31 and the second free end 41 in a straight line. Of course, they can also be fixedly connected by gluing.

[0038] Alternatively, when the first connecting member 310 and the second connecting member 410 are magnets, the first free end 31 and the second free end 41 are fixed to the magnets by in-mold injection molding, that is, the magnets are fixed inside the first free end 31 / the second free end 41 .

[0039] The assembly structure of the left silicone wristband 3, the right silicone wristband 4 and the pressing plate 1 is as follows:

[0040] The lower part of the left silicone wristband 3 is provided with a first connecting foot 33 and a second connecting foot 34 in a twisted shape and in opposite twisting directions, and the twisted surfaces of the first connecting foot 33 and the second connecting foot 34 cooperate to form the first concave position 302.
