[0030] Such as Figures 1-9As shown, an antibacterial stethoscope of the present invention consists of an earring 101, a rubber tube 102 and a stethoscope head 103. A protective ring 2 is sleeved on the rubber tube 102. The protective ring 2 is composed of a first shell 201 and a second shell 202. Openings 203 are formed on the first shell 201 and the second shell 202. A cover plate 204 that matches the opening 203 is hinged on the opening 203. The first shell 201 and the second shell 202 are detachably connected through an installation component. A protective component for antibacterial protection of the front end of the stethoscope head 103 is arranged between the first shell 201 and the second shell 202;

[0031] It should be noted here that: under the mutual cooperation of the protective component and the conveying component, when the stethoscope head 103 on the stethoscope examines the patient, the stethoscope head 103 can be isolated and protected by the protective film 407, and when the stethoscope is used again, the unused protective film 407 can be moved to the front end of the stethoscope head 103 and abutted against it, ensuring that the protective film 407 at the front end of the stethoscope head 103 is not contaminated, ensuring the isolation and protection effect of the stethoscope head 103, and reducing the probability of cross-infection and nosocomial infection during the operation and use of the stethoscope.

[0032] Specifically, the protective component includes a first mounting bracket 401 installed on the first shell 201. A first rotating shaft 402 is rotatably connected to the first mounting bracket 401. A torsion spring for pulling the first rotating shaft 402 to reset after rotation is arranged between the first mounting bracket 401 and the first rotating shaft 402. A mounting roller 403 is installed on the first rotating shaft 402. A protective film 407 is wound on the mounting roller 403. A second mounting bracket 404 is installed inside the second shell 202. A second rotating shaft 405 is rotatably connected to the second mounting bracket 404. A torsion spring for resetting the second rotating shaft 405 after rotation is arranged between the second mounting bracket 404 and the second rotating shaft 405. A winding roller 406 is fixed on the second rotating shaft 405. One end of the protective film 407 passes through the first shell 201 and enters the inside of the second shell 202 and is fixed to the winding roller 406. The protective film 407 outside the first shell 201 and the second shell 202 abuts against the front end of the stethoscope head 103. A conveying component for conveying the winding roller 406 is arranged on the second shell 202;

[0033] It should be noted here that: during the process of sleeving and installing the protective ring 2 on the rubber tube 102, the protective film 407 between the first shell 201 and the second shell 202 abuts against the front end of the stethoscope head 103, so that when the stethoscope head 103 on the stethoscope examines the patient, the stethoscope head 103 is isolated and protected by the protective film 407.

[0034] Specifically, the conveying assembly includes two sets of support frames 501 fixed inside the second housing 202. The protective film 407 passes between the two sets of support frames 501. A mounting shaft 502 is rotatably connected to the support frame 501, and a rubber roller 503 is fixed on the mounting shaft 502. The rubber rollers 503 on the two support frames 501 are respectively abutted and pressed against both sides of the protective film 407. A one-way driving assembly for driving the mounting shaft 502 unidirectionally is arranged on the second housing 202.

[0035] It should be noted here that: through the one-way driving assembly, the mounting shaft 502 on the support frame 501 is driven to rotate. Since the rubber roller 503 on the mounting shaft 502 abuts against the protective film 407, during the rotation of the mounting shaft 502, through the frictional force between the rubber roller 503 and the protective film 407, the protective film 407 is pulled, so that the protective film 407 is conveyed between the first housing 201 and the second housing 202.

[0036] Specifically, the one-way driving assembly includes a disc 601 fixed at one end of the mounting shaft 502. A plurality of transmission blocks 602 are fixedly arranged in an annular array on the disc 601. A strip plate 603 is connected to the two support frames 501 through a sliding assembly. An installation groove 604 is formed on the strip plate 603. A sliding plate 605 is connected to the installation groove 604 through a plurality of connecting springs. The sliding plate 605 is slidably connected to the installation groove 604. A plurality of push plates 606 for abutting and pushing against the transmission blocks 602 are fixedly arranged at the upper end of the sliding plate 605. An inclined surface 607 is formed on one side of each push plate 606. A high-efficiency pushing assembly for efficiently pushing the strip plate 603 is arranged on the second housing 202.

[0037] It should be noted here that: through the high-efficiency pushing assembly, the strip plate 603 after being stressed slides on the support frame 501. During the sliding of the strip plate 603, each push plate 606 on the sliding plate 605 abuts against each transmission block 602 on the disc 601 respectively. Through the abutting action between the push plate 606 and the transmission block 602, the disc 601 and the mounting shaft 502 are driven to rotate. After the driving of the mounting shaft 502 is completed, through transmission, the strip plate 603 is driven to reset. During the reset process, the inclined surfaces 607 of each push plate 606 on the sliding plate 605 abut against the transmission blocks 602 respectively. Through the abutting action between the inclined surface 607 and the transmission block 602, the sliding plate 605 is pushed to contract towards the inside of the installation groove 604, so as to prevent the strip plate 603 from driving the disc 601 and the mounting shaft 502 to rotate in the reverse direction during the reset process.

[0038] Specifically, the sliding assembly includes a T-shaped groove 701 formed on the support frame 501. A T-shaped block 702 that is mutually matched with the T-shaped groove 701 is fixed on one side of the strip plate 603. The T-shaped block 702 is slidably connected to the T-shaped groove 701.

[0039] It should be noted here that: through the T-shaped groove 701 and the T-shaped block 702, the movement of the strip plate 603 after being stressed is guided.

[0040] Specifically, the efficient pushing component includes a connecting shaft 801 rotatably connected inside the second housing 202. A rotating plate 802 is fixed on the connecting shaft 801. A torsion spring is sleeved on the connecting shaft 801, and both ends of the torsion spring are respectively connected to the inner wall of the second housing 202 and the rotating plate 802. A pushing plate 803 is fixed on the rotating plate 802. The pushing plate 803 is connected to the strip plate 603 through a transmission component. A fixing plate 804 is fixed on the pushing plate 803. A push rod 10 for extruding the fixing plate 804 is connected to the second housing 202 through a connecting component, and one end of the push rod 10 abuts against the fixing plate 804;

[0041] It should be noted here that: through the efficient pushing component, it is convenient for the strip plate 603 after transmission to move a longer distance, enabling the mounting shaft 502 to rotate more turns, increasing the length of the protective film 407 conveyed when pressing the push rod 10, and ensuring the effect of conveying and switching the protective film 407 at the front end of the stethoscope head 103.

[0042] Specifically, the transmission component includes a transmission groove 901 opened on the pushing plate 803. A transmission pin 902 is slidably connected to the transmission groove 901, and one end of the transmission pin 902 is fixed to the upper end of the strip plate 603;

[0043] It should be noted here that: during the movement of the pushing plate 803, through the interaction between the transmission groove 901 and the transmission pin 902, the transmission pin 902 and the strip plate 603 are driven to move under force.

[0044] Specifically, the fixing plate 804 is located between the connecting shaft 801 and the transmission groove 901, and the distance between the transmission groove 901 and the connecting shaft 801 is several times the distance between the fixing plate 804 and the connecting shaft 801;

[0045] It should be noted here that: during the process of pushing the strip plate 603 by the pushing plate 803, since the distance between the transmission groove 901 and the connecting shaft 801 is several times the distance between the fixing plate 804 and the connecting shaft 801, when the push rod 10 abuts against and pushes the fixing plate 804, through the lever principle, the strip plate 603 after transmission moves a longer distance, enabling the mounting shaft 502 to rotate more turns, increasing the length of the protective film 407 conveyed when pressing the push rod 10, and ensuring the effect of conveying and switching the protective film 407 at the front end of the stethoscope head 103.

[0046] Specifically, the connecting component includes a U-shaped frame 1101 fixed inside the second housing 202. The push rod 10 is slidably connected to the U-shaped frame 1101. A baffle 1102 is fixed on the push rod 10. A spring 1103 is sleeved on the side wall of the push rod 10. Two ends of the spring 1103 are respectively connected to the U-shaped frame 1101 and the baffle 1102.

[0047] It should be noted here that during the movement of the push rod 10, the spring 1103 is driven to deform under force to generate elastic force. Through the elastic force of the spring 1103, the reset movement of the pushed push rod 10 is facilitated.

[0048] Specifically, the installation component includes a first connecting plate 301 fixed on the first housing 201. A second connecting plate 302 is fixed on the second housing 202. The first connecting plate 301 and the second connecting plate 302 are connected by bolts 303.

[0049] It should be noted here that after the first housing 201 and the second housing 202 on the protective ring 2 are pushed closer to each other from both sides of the rubber tube 102 and abutted against the rubber tube 102, the splicing and installation between the first housing 201 and the second housing 202 are completed through the threaded connection between the bolts 303 and the first connecting plate 301 and the second connecting plate 302.

[0050] Working principle: Before the stethoscope is operated and used, the first housing 201 and the second housing 202 on the protective ring 2 are pushed closer to each other from both sides of the rubber tube 102 and installed and connected through the installation component, so that the protective ring 2 is sleeved and installed on the rubber tube 102 of the stethoscope. During the process of the protective ring 2 being sleeved and installed on the rubber tube 102, the protective film 407 between the first housing 201 and the second housing 202 abuts against the front end of the stethoscope head 103. When the stethoscope head 103 on the stethoscope examines the patient, the stethoscope head 103 is isolated and protected through the protective film 407.

[0051] After the stethoscope is used, the protective film 407 is kept in contact with the front end of the stethoscope head 103, which is convenient for the isolation and protection of the stethoscope during storage. When the stethoscope is used again, through the mutual cooperation of the high-efficiency pushing component, the transmission component and the one-way driving component, the mounting shaft 502 on the support frame 501 is driven to rotate. Since the rubber roller 503 on the mounting shaft 502 abuts against the protective film 407, during the rotation of the mounting shaft 502, through the frictional action between the rubber roller 503 and the protective film 407, the protective film 407 is pulled, so that the protective film 407 is conveyed between the first housing 201 and the second housing 202. Through the conveyance of the protective film 407, the unused protective film 407 is moved to the front end of the stethoscope head 103 and abuts against it, ensuring that when the stethoscope is used again, the protective film 407 at the front end of the stethoscope head 103 is not contaminated, ensuring the isolation and protection effect of the stethoscope head 103, and reducing the probability of cross-infection and nosocomial infection during the operation and use of the stethoscope;

[0052] During the process of driving the mounting shaft 502 on the support frame 501, the push rod 10 is pushed towards the inside of the second housing 202. During the pushing process, through the abutting and pushing action between the push rod 10 and one side of the fixing plate 804, the push plate 803 is pushed to move under force. During the movement of the push plate 803, the connecting shaft 801 on the rotating plate 802 is driven to rotate inside the second housing 202. And during the movement of the push plate 803, through the interaction between the transmission groove 901 and the transmission pin 902, the transmission pin 902 and the strip plate 603 are driven to move under force. During the movement of the strip plate 603, through the sliding guiding action of the T-shaped groove 701 and the T-shaped block 702, the stressed strip plate 603 slides on the support frame 501. During the sliding of the strip plate 603, each push plate 606 on the sliding plate 605 abuts against each transmission block 602 on the disc 601 respectively. Through the abutting action between the push plate 606 and the transmission block 602, the disc 601 and the mounting shaft 502 are rotated. During the whole transmission process, since the distance between the transmission groove 901 and the connecting shaft 801 is several times the distance between the fixing plate 804 and the connecting shaft 801, when the push rod 10 abuts against and pushes the fixing plate 804, through the lever principle, the stressed strip plate 603 moves a longer distance, so that the mounting shaft 502 can rotate more turns, increasing the conveying length of the protective film 407 when the push rod 10 is pressed, and ensuring the conveying and switching effect of the protective film 407 at the front end of the stethoscope head 103.
