Description

Technical Field

[0001] The present invention relates to the technical field of stethoscopes, and particularly to a combined stethoscope. Background Art

[0002] The cardiology department, that is, the cardiovascular medicine department, is a clinical department set up by the large internal medicine departments of hospitals at all levels for the diagnosis and treatment of cardiovascular diseases. The diseases treated include angina pectoris, hypertension, sudden death, arrhythmia, heart failure, premature beats, arrhythmia, myocardial infarction, cardiomyopathy, myocarditis, myocardial infarction and other cardiovascular diseases. During the process of cardiology clinical medicine examination and treatment, a stethoscope is often used to diagnose the diseased part and condition of the patient. Since the stethoscope has been applied to cardiology clinical medicine, its appearance and sound transmission method have been continuously improved, but its basic structure has changed little. It mainly consists of a sound pickup part (chest piece), a conduction part (rubber tube) and a listening part (earpiece).

[0003] After retrieval, the utility model patent with the Chinese patent number CN 214856852 U discloses a combined stethoscope for cardiology clinical medicine, including a device body and a protection device. The device body includes a metal connecting tube, and the protection device is fixedly connected to the metal connecting tube by threads. The device body also includes earplugs and a three-way tube. The earplugs are movably sleeved on the top end of the metal connecting tube. The other end of the three-way tube is provided with a rubber connecting tube, and a sound pickup is arranged at the end of the rubber connecting tube. The sound pickup is fixedly connected to the end point of the rubber connecting tube. Compared with the prior art, the utility model patent with the Chinese patent number CN 214856852 U solves the problem that the contact between the stethoscope and the ear canal is too hard and too tight, making the operator feel uncomfortable.

[0004] However, when the above combined stethoscope for cardiology clinical medicine bears the pressure of the two stethoscope ear tubes on the ear canal through the support rod, it is necessary to ensure that the support rod is in a suitable position to ensure that the distance between the ends of the two stethoscope ear tubes conforms to the distance between the two ear canals of the operator. When adjusting the position of the support rod, it is necessary to simultaneously turn the installation bumps at both ends, and the position adjustment of the support rod cannot be quickly completed, thus affecting the diagnosis efficiency of the operator. Therefore, a combined stethoscope that can avoid the stethoscope ear tubes from pressing on the operator's ear canal and is quick to operate is needed. Summary of the Invention

[0005] The purpose of the present invention is to solve the drawback in the prior art that it can avoid the stethoscope ear tubes from pressing on the operator's ear canal but is not quick to operate, and to propose a combined stethoscope.

[0006] In order to achieve the above purpose, the present invention adopts the following technical scheme:

[0007] A combined stethoscope, comprising a stethoscope head, a conductive rubber tube arranged outside the stethoscope head, two stethoscope ear tubes arranged outside the conductive rubber tube, and earplugs arranged at the ends of the two stethoscope ear tubes. A connecting mechanism for controlling the distance between the two stethoscope ear tubes is arranged between the two stethoscope ear tubes. The connecting mechanism includes two connecting sleeves fixedly connected to the outside of the two stethoscope ear tubes. Connecting rods are hinged to the outside of both connecting sleeves. A connecting cylinder is slidably connected to the outside of the two connecting rods. Limiting grooves are evenly and symmetrically arranged inside the connecting cylinder. Limiting members are arranged inside both connecting rods; A detection mechanism for detecting the heart rate and pulse of a patient is arranged outside the conductive rubber tube. The detection mechanism includes a heart rate detection sensor for detecting the heart rate of the patient and a pulse detection bracelet for detecting the pulse of the patient; A heating mechanism for heating the stethoscope head is further arranged outside the conductive rubber tube. The heating mechanism includes a cover that can slide to the outside of the stethoscope head, and an annular heating sheet is embedded inside the cover.

[0008] The above technical solution further includes:

[0009] The limiting member includes two sliding grooves opened at the end of the connecting rod. Sliders are slidably connected to the inside of the two sliding grooves. Limiting blocks that can enter the inside of the limiting groove are fixedly connected to the outside of the two sliders. Connecting ropes are fixedly connected to the sides of the two limiting blocks close to each other; When the two limiting blocks sliding at the end of the connecting rod enter the limiting groove inside the connecting cylinder, the position between the connecting rod and the connecting cylinder is fixed.

[0010] The limiting member further includes an L-shaped through groove opened in the middle of the connecting rod. A connecting head is slidably connected to the inside of the L-shaped through groove. A fixing ring is fixedly connected to the inside of the L-shaped through groove. A guiding column is also rotatably connected to the inside of the L-shaped through groove.

[0011] The limiting member further includes guiding shafts symmetrically and rotatably connected to the ends of the connecting rod. The two connecting ropes respectively bypass the two connecting ropes and extend into the inside of the L-shaped through groove to be fixedly connected to the connecting head.

[0012] A stranded rope is fixedly connected to the side of the connecting head away from the two connecting ropes. The stranded rope passes through the fixing ring and bypasses the guiding column. The stranded rope extends to the outside of the connecting rod and is fixedly connected to a pull ring. A connecting spring sleeved on the outside of the stranded rope is fixedly connected between the connecting head and the fixing ring; By pulling up the pull ring, the two limiting blocks can be separated from the limiting groove inside the connecting cylinder, so that the connecting rod can slide freely inside the connecting cylinder.

[0013] The detection mechanism further includes a fixed sleeve fixedly connected to the conduction rubber tube. An externally fixed timing display base is provided on the outer part of the fixed sleeve. An interconnected power storage module and signal processing module are provided inside the timing display base. A heart rate connecting wire and a pulse connecting wire, both electrically connected to the signal processing module, are respectively provided on the outer part of the timing display base. The power storage module supplies power to the signal processing module and the timing display base.

[0014] The heart rate detection sensor and the pulse detection bracelet are respectively arranged at one ends of the heart rate connecting wire and the pulse connecting wire away from the timing display base. The heart rate detection sensor and the pulse detection bracelet can transmit the detected heart rate times and pulse times to the timing display base through the heart rate connecting wire and the pulse connecting wire, so that the timing display base can display the heart rate times and pulse times of the patient within the detection time.

[0015] The heating mechanism further includes an outer damping sleeve fixedly connected to the outside of the conduction rubber tube. An inner damping sleeve is arranged outside the outer damping sleeve. The cover is fixedly connected to the end of the inner damping sleeve. A storage battery connected to the annular heating sheet is arranged inside the cover. An elastic switch is arranged outside the storage battery. The elastic switch is used to control the opening and closing of the annular heating sheet. When the elastic switch is turned on, the annular heating sheet is powered on for heating.

[0016] The present invention has the following beneficial effects:

[0017] 1. In the present invention, the connecting mechanism bears the pressing force of the two stethoscope ear tubes on the ear canal. When wearing the two stethoscope ear tubes, only need to pull up the pull ring to disengage the two limit blocks from the limit grooves inside the connecting cylinder, then the connecting rod can slide freely inside the connecting cylinder. Just loosen the pull ring to make the two limit blocks enter the limit grooves inside the connecting cylinder, and the connecting rod can be fixed inside the connecting cylinder. That is, while avoiding the stethoscope ear tubes pressing on the operator's ear canal, the wearing operation of the two stethoscope ear tubes is fast, which can improve the diagnosis efficiency of the operator.

[0018] 2. In the present invention, by attaching the heart rate detection sensor to the chest skin of the patient and wearing the pulse detection bracelet on the patient's wrist, the heart rate detection sensor and the pulse detection bracelet can transmit the detected heart rate times and pulse times to the timing display base through the heart rate connecting wire and the pulse connecting wire, so as to facilitate the operator to judge whether the heart rate times and pulse times of the patient are normal.

[0019] 3. In the present invention, by sliding the cover to make the stethoscope head enter the inside of the sliding cover, the stethoscope head will squeeze and open the elastic switch, then the annular heating sheet can be powered on to heat the stethoscope head inside the cover, avoiding the cold stethoscope head from stimulating the patient's senses and affecting the auscultation effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Embodiment 1

[0029] As shown in Figure 1-4As shown in the figure, a combined stethoscope proposed by the present invention includes a stethoscope head 1, a conductive rubber tube 2 disposed outside the stethoscope head 1, two stethoscope ear tubes 3 disposed outside the conductive rubber tube 2, and earplugs 4 disposed at the ends of the two stethoscope ear tubes 3. A connecting mechanism 5 for controlling the distance between the two is disposed between the two stethoscope ear tubes 3. The connecting mechanism 5 includes two connecting sleeves 51 fixedly connected to the outside of the two stethoscope ear tubes 3. Connecting rods 52 are hinged to the outside of the two connecting sleeves 51. A connecting cylinder 53 is slidably connected to the outside of the two connecting rods 52. Limiting grooves 54 are uniformly and symmetrically formed on the inner side of the connecting cylinder 53. Limiting members 55 are disposed inside the two connecting rods 52;

[0030] The limiting member 55 includes two sliding grooves 551 formed at the ends of the connecting rod 52. Sliding blocks 552 are slidably connected to the inside of the two sliding grooves 551. Limiting blocks 553 that can enter the inside of the limiting groove 54 are fixedly connected to the outside of the two sliding blocks 552. Connecting ropes 554 are fixedly connected to the side of the two limiting blocks 553 close to each other. When the two limiting blocks 553 sliding at the end of the connecting rod 52 enter the inside of the limiting groove 54 on the inner side of the connecting cylinder 53, the position between the connecting rod 52 and the connecting cylinder 53 is fixed. The limiting member 55 further includes an L-shaped through groove 555 formed in the middle of the connecting rod 52. A connecting head 556 is slidably connected to the inside of the L-shaped through groove 555. A fixing ring 557 is fixedly connected to the inside of the L-shaped through groove 555. A guiding column 558 is also rotatably connected to the inside of the L-shaped through groove 555;

[0031] The limiting member 55 further includes guiding shafts 559 symmetrically and rotatably connected to the ends of the connecting rod 52. The two connecting ropes 554 respectively bypass the two connecting ropes 559 and extend into the inside of the L-shaped through groove 555 to be fixedly connected to the connecting head 556. A stranded rope 560 is fixedly connected to the side of the connecting head 556 away from the two connecting ropes 554. The stranded rope 560 passes through the fixing ring 557 and bypasses the guiding column 558. The stranded rope 560 extends to the outside of the connecting rod 52 and is fixedly connected to a pull ring 561. By pulling up the pull ring 561, the two limiting blocks 553 can be separated from the limiting groove 54 on the inner side of the connecting cylinder 53, so that the connecting rod 52 can freely slide inside the connecting cylinder 53. A connecting spring 562 sleeved on the outside of the stranded rope 560 is fixedly connected between the connecting head 556 and the fixing ring 557. The connecting spring 562 is used to assist the two limiting blocks 553 to enter the limiting groove 54 inside.

[0032] In this embodiment: By simultaneously pulling up the two pull rings 561, the pull rings 561 drive the connecting rope 554 through the stranded rope 560. The two driven connecting ropes 554 will drive the two limit blocks 553 to move towards each other (during the process of the two limit blocks 553 moving towards each other, the two sliders 552 will slide inside the two chutes 551 respectively and approach each other, and the connecting head 556 will slide towards the fixed ring 557 and compress the connecting spring 562). After the two limit blocks 553 are disengaged from the limit slots 54 inside the connecting cylinder 53, the two connecting rods 52 can slide freely inside the connecting cylinder 53 at this time, that is, the distance between the two stethoscope ear tubes 3 can be freely changed. Then, without releasing the two pull rings 561, wear the two stethoscope ear tubes 3;

[0033] After the two stethoscope ear tubes 3 are worn, release the two pull rings 561 simultaneously. The compressed connecting spring 562 will drive the connecting head 556 and the stranded rope 560 to reset, so that the two limit blocks 553 move away from each other and enter the limit slots 54 inside the connecting cylinder 53. At this time, the two connecting rods 52 can be fixed inside the connecting cylinder 53, that is, the distance between the two stethoscope ear tubes 3 is fixed;

[0034] This combined stethoscope bears the pressure of the two stethoscope ear tubes 3 on the ear canal through the connecting mechanism 5. And when wearing the two stethoscope ear tubes 3, just pull up the pull rings 561 to disengage the two limit blocks 553 from the limit slots 54 inside the connecting cylinder 53, then the connecting rods 52 can slide freely inside the connecting cylinder 53. Just release the pull rings 561 to make the two limit blocks 553 enter the limit slots 54 inside the connecting cylinder 53, then the connecting rods 52 can be fixed inside the connecting cylinder 53. That is, while avoiding the stethoscope ear tubes from pressing the operator's ear canal, the wearing operation of the two stethoscope ear tubes 3 is fast and can improve the diagnosis efficiency of the operator.

[0035] Embodiment Two

[0036] As Figure 1 and Figure 5 shown, based on Embodiment One, a detection mechanism 6 for detecting the heart rate and pulse of the patient is arranged outside the conduction rubber tube 2. The detection mechanism 6 includes a heart rate detection sensor 61 for detecting the heart rate of the patient and a pulse detection bracelet 62 for detecting the pulse of the patient. A pulse sensor is installed on the inner side of the pulse detection bracelet 62. The detection mechanism 6 further includes a fixed sleeve 63 fixedly connected to the conduction rubber tube 2. An external fixed connection of the fixed sleeve 63 has a timing display base 64. A power storage module and a signal processing module are arranged inside the timing display base 64. The power storage module supplies power to the signal processing module and the timing display base 64;

[0037] The outer part of the timing display base 64 is respectively provided with a heart rate connecting wire 65 and a pulse connecting wire 66 that are electrically connected to the signal processing module. The heart rate detection sensor 61 and the pulse detection bracelet 62 are respectively arranged at one end of the heart rate connecting wire 65 and the pulse connecting wire 66 away from the timing display base 64. The heart rate detection sensor 61 and the pulse detection bracelet 62 can transmit the detected heart rate times and pulse times to the timing display base 64 through the heart rate connecting wire 65 and the pulse connecting wire 66, so that the timing display base 64 can display the heart rate times and pulse times of the patient within the detection time.

[0038] In this embodiment: By attaching the heart rate detection sensor 61 to the chest skin of the patient and wearing the pulse detection bracelet 62 on the patient's wrist, and then turning on the switch of the timing display base 64, the heart rate detection sensor 61 and the pulse detection bracelet 62 can transmit the detected heart rate times and pulse times to the timing display base 64 through the heart rate connecting wire 65 and the pulse connecting wire 66, and the timing display base 64 can display the heart rate times and pulse times of the patient within the detection time to judge whether the heart rate times and pulse times of the patient are normal;

[0039] While auscultating through the stethoscope head 1, by attaching the heart rate detection sensor 61 to the chest skin of the patient and wearing the pulse detection bracelet 62 on the patient's wrist, this combined stethoscope can enable the heart rate detection sensor 61 and the pulse detection bracelet 62 to transmit the detected heart rate times and pulse times to the timing display base 64 through the heart rate connecting wire 65 and the pulse connecting wire 66, so as to facilitate the operator to judge whether the heart rate times and pulse times of the patient are normal.

[0040] Embodiment Three

[0041] As Figure 1 and Figure 6 shown, based on Embodiment One and Embodiment Two, a heating mechanism 7 for heating the stethoscope head 1 is further provided outside the conduction rubber tube 2. The heating mechanism 7 includes a housing 71 that can slide to the outside of the stethoscope head 1. An annular heating sheet 72 is embedded inside the housing 71. The heating mechanism 7 further includes an outer damping sleeve 73 fixedly connected to the outside of the conduction rubber tube 2. An inner damping sleeve 74 is arranged outside the outer damping sleeve 73. The housing 71 is fixedly connected to the end of the inner damping sleeve 74. A storage battery 75 connected to the annular heating sheet 72 is arranged inside the housing 71. An elastic switch 76 is arranged outside the storage battery 75. The elastic switch 76 is used to control the opening and closing of the annular heating sheet 72. When the elastic switch 76 is turned on, the annular heating sheet 72 is powered on for heating.

[0042] In this embodiment: By sliding the housing 71, the inner damping sleeve 74 slides along the outer side of the outer damping sleeve 73. During this process, the stethoscope head 1 will enter the inside of the sliding housing 71 and squeeze the elastic switch 76 to open the elastic switch 76. When the elastic switch 76 is opened, the annular heating sheet 72 is energized and heated. The annular heating sheet 72 being energized and heated can heat the stethoscope head 1 inside the housing 71. After the stethoscope head 1 is heated to an appropriate body surface temperature, the sliding housing 71 is reset. After the housing 71 is reset, the elastic switch 76 will reset to cut off the power supply to the annular heating sheet 72;

[0043] In this combined stethoscope, by sliding the housing 71 to make the stethoscope head 1 enter the inside of the sliding housing 71 and squeezing to open the elastic switch 76, the annular heating sheet 72 can be energized to heat the stethoscope head 1 inside the housing 71, avoiding the cold stethoscope head 1 from stimulating the patient's senses and affecting the auscultation effect.

[0044] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
