Description

Technical Field

[0001] The utility model relates to the technical field of medical accessories, in particular to an air bag type back hammer. Background Art

[0002] In clinical practice, back patting is usually a physical therapy method. Rhythmic patting or vibration is applied to the patient's back with the hands or special equipment to help the patient clear mucus or secretions in the respiratory tract and promote the patency of the respiratory system. Back patting is usually used to treat respiratory diseases such as bronchitis, pneumonia, asthma, etc. Back patting is also used to treat other respiratory tract effusions or secretions. Back patting therapy helps stimulate the ciliary movement of respiratory epithelial cells, promote the discharge of mucus, and improve the patient's respiratory function by increasing lung capacity and improving ventilation. This treatment is usually performed by professional medical staff and is personalized according to the patient's specific situation and the severity of the disease. When the doctor uses his hands to pat the patient on the back, the traditional way of operation is: the doctor puts his five fingers together in a half-fist posture, forms an empty fist with the palm of his hand, and pats the patient's back with the empty fist to achieve the purpose of treatment.

[0003] However, in actual operation, the inventor found that the method of patting the patient's back with an empty fist still has some shortcomings, specifically:

[0004] When the doctor pats the patient's back with his empty fist, it is the doctor's five fingers, thenar and hypothenar that contact the patient's back. During the patting process, the order of the points where the patient's back contacts the doctor's hand changes. The patient's back may first contact one of the five fingers, then the remaining fingers, and then the thenar or hypothenar. It may also first contact the hypothenar or thenar, and then the five fingers. This results in uneven force on the patient's back, resulting in poor patting effect and discomfort to the patient. Furthermore, long-term continuous patting can easily make the doctor feel tired, resulting in changes in the doctor's patting rhythm, inconsistent doctor's hand falling movements, and more uneven force on the patient's back, further resulting in poor patting effect. At the same time, long-term continuous patting can easily damage the doctor's hands, which is not good for the doctor's health.

[0005] Therefore, based on the above-mentioned shortcomings, it is urgently needed to design a kind of air bag type back hammer. Utility Model Content

[0006] The utility model aims to provide an air bag back patting hammer to solve the above-mentioned problem that the force on the patient's back is uneven during the actual operation of the current back patting method.

[0007] In order to achieve the above-mentioned invention object, the utility model provides the following technical solutions:

[0008] An airbag back-slapping hammer comprises a hammer body and a handle arranged on the hammer body, wherein the handle is used for being held by hand, the hammer body is a hollow airbag, and the hammer body is in an expanded state.

[0009] As a priority technical solution of the present application, a top plate is provided on the top of the hammer body, and a knocking device is provided below the top plate. When the hammer body strikes the patient's back, the knocking device strikes the patient's back for the second time, and a reserved gap is provided between the knocking device and the bottom of the hammer body.

[0010] As a priority technical solution of the present application, the knocking device includes a pipe, one end of the pipe is connected to the top plate, the other end is suspended and has a through hole in the middle, a knocking rod is slidably arranged in the pipe, one end of the knocking rod close to the top plate has the same size as the inner wall of the pipe, and the other end is connected to a knocking ball after passing through the through hole, a spring is sleeved on the knocking rod, and the spring is located in the pipe, and an air inlet is arranged on the side wall of the pipe close to the top plate, and the size of the air inlet is larger than the size of the through hole.

[0011] As a preferred technical solution of the present application, a fan blade is provided at one end of the knocking rod close to the top plate, and the rotation of the fan blade is used to drive the knocking rod to rotate.

[0012] As a preferred technical solution of the present application, the material of the striking ball is rubber.

[0013] As a preferred technical solution of the present application, the striking ball is a hollow ball.

[0014] As a preferred technical solution of the present application, there are several air inlet holes.

[0015] As a preferred technical solution of the present application, there are several striking devices.

[0016] As a preferred technical solution of the present application, a plurality of the knocking devices are distributed below the top plate.

[0017] As a preferred technical solution of the present application, an air charging port is provided on the hammer body, and the air charging port is used for charging and deflating air.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. In the scheme of the present application, the setting of the handle is convenient for the doctor to hold the hammer with his hand. When the doctor hits the patient's back with the hammer, the applied force first squeezes the airbag, so that the air in the airbag is compressed to form a stable force-bearing surface, and then the force is evenly applied to the patient's back through the airbag, so that the patient's back is evenly stressed, achieving an ideal hammering effect; further, when the applied force is too large, the air in the airbag can also play a certain buffering and force-unloading role, avoiding the pain of the patient's back caused by the sudden excessive force, which is beneficial to the protection of the patient. Further, the setting of the hammer avoids the doctor's hand from directly contacting the patient's back, avoiding the damage to the doctor's hand caused by a hard collision, which is beneficial to the protection of the doctor's hand. At the same time, the hammer plays a buffering role on the doctor's hand, so that the reaction force applied by the hammer to the doctor's hand is more uniform, which is further beneficial to the protection of the doctor's hand;

[0020] 2. When the doctor uses the hammer to hit the patient's back, the bottom of the hammer first contacts the patient's back to achieve a single hit, and the patient's back reacts to the hammer. The hammer is forced to squeeze the air inside the hammer, and the air inside the hammer enters the pipeline through the air inlet and acts on the top of the knocking rod. The knocking rod compresses the spring and moves downward, and the knocking ball moves downward with the knocking rod until it contacts the bottom of the hammer. The force generated by the knocking ball moving downward is transmitted to the patient's back through the bottom of the hammer, achieving a double hit effect. In the present application, the force of the hammer compressed air acting on the top of the knocking rod is greater than the elastic force of the spring on the knocking rod;

[0021] 3. The hammer is subjected to force to squeeze the air inside the hammer. The air inside the hammer enters the pipeline through the air inlet and acts on the fan blades on the top of the knocking rod. The fan blades are forced to rotate, and the rotation of the fan blades drives the knocking rod to rotate. At the same time, the knocking rod compresses the spring to move downward, and the knocking ball moves downward with the knocking rod until it contacts the bottom of the hammer. The knocking ball also rotates with the knocking rod. The force generated by the downward movement of the knocking ball is transmitted to the patient's back through the bottom of the hammer, achieving the effect of secondary hammering. At the same time, the rotation of the knocking ball is transmitted to the patient's back through the bottom of the hammer, achieving the effect of massage. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] Example 1: See Figure 1 and Figure 2 As shown,

[0031] The present embodiment provides an airbag back-slapping hammer, comprising a hammer body 1 and a handle 2 arranged on the hammer body 1, wherein the handle 2 is used for being held by hand, the hammer body 1 is a hollow airbag, and the hammer body 1 is in an expanded state.

[0032] The setting of the handle 2 is convenient for the doctor to hold the hammer body 1 with his hand. When the doctor hits the patient's back with the hammer body 1, the applied force first squeezes the airbag, so that the air in the airbag is compressed to form a stable force-bearing surface, and then the force is evenly applied to the patient's back through the airbag, so that the patient's back is evenly stressed and an ideal beating effect is achieved; further, when the applied force is too large, the air in the airbag can also play a certain buffering and force-unloading role, avoiding pain in the patient's back caused by sudden excessive force, which is beneficial to the protection of the patient. Further, the setting of the hammer body 1 avoids direct contact between the doctor's hand and the patient's back, avoiding damage to the doctor's hand caused by a head-on collision, which is beneficial to the protection of the doctor's hand. At the same time, the hammer body 1 plays a buffering role on the doctor's hand, so that the reaction force applied by the hammer body 1 to the doctor's hand is more uniform, which is further beneficial to the protection of the doctor's hand.

[0033] As a preferred embodiment, on the basis of the above-mentioned method, further, a top plate 11 is provided on the top of the hammer body 1, and a knocking device 3 is provided below the top plate 11. When the hammer body 1 strikes the patient's back, the knocking device 3 strikes the patient's back for the second time, and a reserved gap is provided between the knocking device 3 and the bottom of the hammer body 1.

[0034] The top plate 11 is used to carry the knocking device 3, and the knocking device 3 is used to achieve secondary knocking of the patient's back. In this way, an additional knocking effect is added, which is beneficial to reducing the number of knocks by the doctor, is beneficial to protecting the doctor's hands, and is beneficial to improving the treatment efficiency of the patient.

[0035] As a preferred embodiment, on the basis of the above-mentioned method, further, the knocking device 3 includes a pipe 31, one end of the pipe 31 is connected to the top plate 11, the other end is suspended and a through hole 311 is opened in the middle, a knocking rod 32 is slidably arranged in the pipe 31, the end of the knocking rod 32 close to the top plate 11 is the same size as the inner wall of the pipe 31, and the other end is connected to a knocking ball 33 after passing through the through hole 311, the knocking rod 32 is sleeved with a spring 34, and the spring 34 is located in the pipe 31, and the side wall of the pipe 31 close to the top plate 11 is provided with an air inlet hole 312, and the size of the air inlet hole 312 is larger than the size of the through hole 311.

[0036] When the doctor uses the hammer 1 to strike the patient's back, the bottom of the hammer 1 first contacts the patient's back to achieve one strike, and the patient's back reacts to the hammer 1. The hammer 1 is forced to squeeze the air inside the hammer 1, and the air inside the hammer 1 enters the pipe 31 through the air inlet 312 to act on the top of the knocking rod 32. The knocking rod 32 compresses the spring 34 to move downward, and the knocking ball 33 follows the knocking rod 32 to move downward until it contacts the bottom of the hammer 1. The force generated by the downward movement of the knocking ball 33 is transmitted to the patient's back through the bottom of the hammer 1, achieving the effect of a second strike; in the present application, the force of the hammer 1 compressing the air acting on the top of the knocking rod 32 is greater than the elastic force of the spring 34 on the knocking rod 32.

[0037] As a preferred embodiment, on the basis of the above-mentioned manner, further, a fan blade 321 is provided at one end of the knocking rod 32 close to the top plate 11, and the rotation of the fan blade 321 is used to push the knocking rod 32 to rotate.

[0038] The hammer body 1 is subjected to force to squeeze the air inside the hammer body 1. The air inside the hammer body 1 enters the pipe 31 through the air inlet hole 312 to act on the fan blade 321 at the top of the knocking rod 32. The fan blade 321 is forced to rotate, and the rotation of the fan blade 321 drives the knocking rod 32 to rotate. At the same time, the knocking rod 32 compresses the spring 34 to move downward, and the knocking ball 33 moves downward with the knocking rod 32 until it contacts the bottom of the hammer body 1. The knocking ball 33 also rotates with the knocking rod 32. The force generated by the downward movement of the knocking ball 33 is transmitted to the patient's back through the bottom of the hammer body 1, thereby achieving a secondary hammering effect. At the same time, the rotation of the knocking ball 33 is transmitted to the patient's back through the bottom of the hammer body 1, thereby achieving a massage effect.

[0039] As a preferred embodiment, based on the above embodiment, further, the material of the striking ball 33 is rubber.

[0040] The rubber striking ball 33 is flexible. When the bottom of the hammer body 1 acts on the patient's back, the striking ball 33 has a certain deformation space, thereby avoiding injury to the patient's back caused by a hard collision, which is beneficial to protecting the patient's back.

[0041] As a preferred embodiment, on the basis of the above-mentioned embodiment, further, the striking ball 33 is a hollow ball.

[0042] The striking ball 33 is set to be hollow, which reduces the weight of the striking ball 33. When striking the patient's back, the greater force generated by the striking ball 33 due to inertia is reduced, further causing pain in the patient's back, which is beneficial to protecting the patient. Furthermore, the hollow setting allows the striking ball 33 to have a larger deformation space. When the striking force is too large, the hollow striking ball 33 can also play a certain buffering and force-unloading role, avoiding pain in the patient's back caused by excessive force, which is beneficial to protecting the patient.

[0043] As a preferred implementation, based on the above-mentioned implementation, further, the number of the air inlet holes 312 is multiple.

[0044] The provision of multiple air inlet holes 312 increases the air inlet channel, which is beneficial for compressed air to quickly enter the pipe 31, forming a force on the knocking rod 32. At the same time, more compressed air can enter the pipe 31, forming a greater force on the knocking rod 32. In this way, the elastic force of the spring 34 can be set to be larger, making the structure of the spring 34 stronger, which is beneficial to increase the number of times the spring 34 can be compressed and improve the service life of the knocking device 3.

[0045] As a preferred implementation, based on the above-mentioned implementation, further, the number of the knocking devices 3 is several.

[0046] The provision of multiple knocking devices 3 increases the number of secondary strikes and the action area of ​​the knocking ball 33, which is beneficial to speed up the unobstructed respiratory tract of the patient and is beneficial to the treatment of the patient.

[0047] As a preferred implementation, on the basis of the above-mentioned implementation, further, a plurality of the striking devices 3 are evenly distributed below the top plate 11 .

[0048] A plurality of knocking devices 3 are evenly distributed below the top plate 11 , so that the action area of ​​the knocking devices 3 is more uniform, which is convenient for doctors to control the area of ​​the knocking action and is beneficial to the treatment of patients.

[0049] As a preferred embodiment, on the basis of the above-mentioned embodiment, further, the hammer body 1 is provided with an air charging port 12, and the air charging port 12 is used for charging and discharging air.

[0050] The setting of the inflation port 12 is convenient for inflating or deflating the hammer body 1. When in use, the hammer body 1 is inflated through the inflation port 12, so that the hammer body 1 is in an expanded state to realize the function of the hammer body 1. When not in use, the hammer body 1 is deflated through the inflation port 12, so that the hammer body 1 is deflated, which is convenient for storage, thereby improving the flexibility of using the airbag back-slapping hammer of the present application.

[0051] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods.
