Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a multi-purpose portable stethoscope. Background Technology

[0002] A stethoscope is a medical instrument used to listen to sounds inside the body. It is an important method for doctors to examine patients and diagnose diseases. Since its clinical application, the stethoscope has undergone continuous improvements in appearance and sound transmission, but its basic structure has not changed much. It mainly consists of a pickup part (chest part), a transmission part (rubber tube), and an auditory part (ear part).

[0003] Chinese patent (application number: CN202120951097.X) discloses a multifunctional stethoscope, including a stethoscope head and a stethoscope tube connected to the stethoscope head, and also includes a circuit part located on the stethoscope head, the circuit part including: an infrared temperature measurement module for measuring and displaying temperature;

[0004] The patent and existing technologies have the following technical problems in practical use:

[0005] 1. This stethoscope uses a built-in lighting module and heating wire directly on the stethoscope head for illumination and heating. This results in a bulky stethoscope structure, making it inconvenient for doctors to use and increasing manufacturing costs.

[0006] 2. This stethoscope does not have a storage function. Due to the long length of the stethoscope's conductive part (rubber tube), it is not only inconvenient to carry, but also causes interference when using the lighting or other functions, making it inconvenient to use.

[0007] 3. This stethoscope does not have a blood oxygen testing function. During ward rounds, it is necessary to measure the patient's heart rate and blood oxygen, and it is very inconvenient to carry an extra blood oxygen measuring device. Summary of the Invention

[0008] The purpose of this invention is to solve the problems of existing stethoscopes, such as limited functionality, complex structure, and inability to be stored. This invention provides a multi-purpose portable stethoscope.

[0009] To achieve the above objectives, the present invention specifically adopts the following technical solution:

[0010] A multi-purpose portable stethoscope includes an ear tube, an ear reed, a Y-tube, a sound transmission tube, and a stethoscope head. The outer side of the Y-tube is provided with a storage cover for housing the sound transmission tube. A fingertip pulse oximeter is installed on the outer side of the storage cover. The storage head is sleeved on the outer side of the sound transmission tube. An outer ring box is provided on the outer side of the stethoscope head. The storage heads can be installed in the storage cover.

[0011] The outer ring box has a lifting mounting ring inside, and an LED lamp head is arranged in a ring at the bottom of the mounting ring. The bottom of the outer ring box has a probe hole in a ring, and the LED lamp head can be inserted into the probe hole. The bottom of the outer ring box has a sliding groove, and a sealing plate that can seal the probe hole is slidably connected inside the sliding groove.

[0012] Furthermore, both the storage cover and the storage head are tapered.

[0013] Furthermore, the outer side of the receiving head is provided with a spiral guide groove that can be coiled around the sound transmission hose.

[0014] Furthermore, the inner wall of the storage cover is provided with an internal thread, the outer side of the storage head is provided with an external thread, the top of the outer ring box is provided with a connecting groove, the inner wall of the connecting groove is also provided with an internal thread, and the external thread can be threadedly connected with the internal thread.

[0015] Furthermore, a transmission air ring is provided inside the connecting groove, and an air hole is provided at the bottom of the inner ring box. The air hole is connected to the transmission air ring through an air pipe, and a piston rod is provided at the bottom of the mounting ring and is slidably connected in the air hole.

[0016] Furthermore, the sealing sheet is designed in a ring shape and is staggered with the probe hole. Adjacent sealing sheets are connected by a connecting arc rod. An adjustment groove is provided on the outer side of the slide groove, and a paddle that can be inserted into the adjustment groove is provided on the outer side of the sealing sheet.

[0017] Furthermore, the radius of the sealing sheet is larger than the radius of the probe hole, and the connecting arc rod is arranged along the outer edge of the sealing sheet.

[0018] Furthermore, the angle of the adjustment groove is the same as the angle between the sealing plate and the probe hole.

[0019] Furthermore, the inside of the storage head is lined with aluminum foil insulation material.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This invention provides illumination by setting an outer ring box on the outside of the stethoscope head and installing an LED light inside the outer ring box. A liftable mounting ring retracts the LED light into the outer ring box, and a sealing plate seals the probe hole. The stethoscope head is then installed on the outer ring box, creating a sealed space inside. The heat generated by the LED light preheats the stethoscope head, making it suitable for winter use. The device is also compact and highly functional.

[0022] 2. In this invention, by spirally winding the sound transmission hose around the storage head and then installing the storage head in the storage cover, the device can be centrally stored in the Y-tube position, making it easy to carry. At the same time, the outer ring box is installed on the storage head. At this time, the ear tube is used as a handle and the stethoscope head is used as an illumination head. Since the two are concentrated together, they are not affected by the sound transmission hose, making illumination convenient. The ear tube can also be worn on the head to increase the illumination function.

[0023] 3. In this invention, by installing the storage head on the stethoscope head without closing the probe hole, the cavity formed by the storage head and the outer ring box can amplify the sound, thereby increasing the range of use of the stethoscope.

[0024] 4. This invention allows for easy measurement by inserting a finger into a fingertip pulse oximeter, making it highly functional. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] like Figures 1-6As shown, a multi-purpose portable stethoscope includes an ear tube 1, an ear reed 2, a Y-tube 3, a sound transmission hose 4, and a stethoscope head 5. A storage cover 6 is provided on the outside of the Y-tube 3 to house the sound transmission hose 4. A fingertip pulse oximeter 22 is installed on the outside of the storage cover 6. A storage head 7 is sleeved on the outside of the sound transmission hose 4. An outer ring box 9 is provided on the outside of the stethoscope head 5. The storage heads 7 can be installed in the storage cover 6.

[0034] The outer ring box 9 has a lifting mounting ring 14 inside. An LED lamp head 15 is arranged in a ring at the bottom of the mounting ring 14. A probe hole 12 is opened in a ring at the bottom of the outer ring box 9. The LED lamp head 15 can be inserted into the probe hole 12. A sliding groove 17 is opened at the bottom of the outer ring box 9. A sealing plate 19 that can seal the probe hole 12 is slidably connected inside the sliding groove 17.

[0035] When in use, remove the storage head 7 from the storage cover 6, and then unfold the sound transmission hose 4 stored inside. At this time, use the stethoscope head 5 to perform normal auscultation. When it is necessary to amplify the auscultation sound, install the storage head 7 on the outer ring box 9, and at the same time control the lifting and lowering of the mounting ring 14. The mounting ring 14 drives the LED lamp head 15 away from the probe hole 12. At this time, the cavity formed between the storage head 7 and the outer ring box 9 can amplify the sound, thereby expanding the auscultation range.

[0036] When lighting is needed, the storage head 7 is removed from the outer ring box 9. At this time, the LED lamp head 15 is powered on for lighting. Since the LED lamp head 15 is arranged in a ring, the lighting effect is good. At this time, the stethoscope head 5 is moved by hand to directly provide lighting. At the same time, since the storage head 7 is away from the stethoscope head 5, the probe hole 12 is ventilated, and the LED lamp head 15 can dissipate heat normally and operate stably. The charging power supply installed in the mounting ring 14 provides power to the LED lamp head 15, and the structure is compact.

[0037] Alternatively, the sound transmission hose 4 can be wrapped around the storage head 7, and then the storage head 7 can be installed on the storage cover 6. At this time, the sound transmission hose 4 is stored in the storage cover 6. Then, the outer ring box 9 and the stethoscope head 5 can be installed on the storage head 7. The probe hole 12 is still open for ventilation. At this time, the stethoscope head 5, the Y tube 3 and the ear tube 1 are integrated. The ear tube 1 can be directly worn on the head. Since the ear tube 1 and the stethoscope head 5 are integrated, the stethoscope can be used as a headlamp. The ear tube 1 can be held by hand for illumination. The illumination is not affected by the sound transmission hose 4. It is convenient to use and has multiple lighting functions.

[0038] When the device is used in winter, the storage head 7 is installed on the outer ring box 9, and then the mounting ring 14 is raised and lowered. The mounting ring 14 moves the LED lamp head 15 away from the probe hole 12. The probe hole 12 is blocked by the sealing plate 19. At this time, a sealed space is formed between the storage head 7 and the outer ring box 9. Then, the LED lamp head 15 is opened. The heat generated by the operation of the LED lamp head 15 cannot be dissipated, thus preheating the stethoscope head 5. It only needs to be preheated to the temperature of the human body surface. No large amount of heat is required. Therefore, the LED lamp head 15 will not be damaged when it is operated in a sealed environment for a short time.

[0039] When the device needs to be stored, the sound transmission hose 4 is wrapped around the storage head 7, and then the storage head 7 is installed on the storage cover 6. At this time, the sound transmission hose 4 is stored in the storage cover 6. Then, the outer ring box 9 and the stethoscope head 5 are installed on the storage head 7. At this time, the stethoscope head 5, the Y tube 3 and the ear tube 1 are integrated into one unit, making it easy to carry.

[0040] When a blood oxygen test is required, insert your finger into the fingertip pulse oximeter 22 for measurement; it is highly functional.

[0041] This stethoscope, with the addition of a lighting component, can expand the auscultation range, preheat the stethoscope head, and offer multiple functions such as multi-functional lighting and foldable storage. Its compact structure and low manufacturing cost make it suitable for widespread adoption.

[0042] like Figure 1 As shown, in some embodiments, both the storage cover 6 and the storage head 7 are tapered. This design allows the sound transmission hose 4 to be more easily coiled around the storage cover 6, resulting in better storage performance.

[0043] like Figure 6 As shown, in some embodiments, the outer side of the receiving head 7 is provided with a spiral guide groove 8 that can be coiled around the sound transmission hose 4. The spiral guide groove 8 further improves the coiling stability of the sound transmission hose 4.

[0044] like Figure 1 , Figure 2 , Figure 6 As shown, in some embodiments, the inner wall of the storage cover 6 is provided with an internal thread, the outer side of the storage head 7 is provided with an external thread, the top of the outer ring box 9 is provided with a connecting groove 10, the inner wall of the connecting groove 10 is also provided with an internal thread, and the external thread can be threadedly connected with the internal thread.

[0045] With the external and internal threads, the storage head 7 can be easily and tightly installed on the storage cover 6 and the outer ring box 9, making installation convenient. With the connection groove 10, when the storage head 7 is threaded onto the outer ring box 9, the contact part between the storage head 7 and the outer ring box 9 is stepped, improving the sealing effect.

[0046] like Figure 2 , Figure 3 As shown, in some embodiments, a transmission air ring 11 is provided inside the connecting groove 10, and an air hole 13 is provided at the bottom of the inner ring box 9. The air hole 13 is connected to the transmission air ring 11 through an air pipe, and a piston rod 16 is provided at the bottom of the mounting ring 14 and is slidably connected in the air hole 13.

[0047] By providing a transmission air ring 11 inside the connecting groove 10, the sealing performance of the connection between the storage head 7 and the outer ring box 9 can be further improved;

[0048] When the receiving head 7 is threaded into the connecting groove 10, the receiving head 7 squeezes the transmission air ring 11. The gas inside the transmission air ring 11 is forced into the air hole 13 through the air pipe. The air pressure inside the air hole 13 increases, and the air pressure pushes the piston rod 16 to rise. The piston rod 16 drives the mounting ring 14 to rise. The mounting ring 14 drives the LED lamp head 15 away from the probe hole 12. This ensures that when the receiving head 7 is sealed with the outer ring box 9, the probe hole 12 can still ventilate and dissipate heat, so that the LED lamp head 15 can operate stably. The probe hole 12 is only blocked when preheating is required to prevent damage to the LED lamp head 15 due to misoperation. Moreover, no additional drive is required for the mounting ring 14. The mounting ring 14 can be driven to rise during installation, resulting in a compact structure.

[0049] When the storage head 7 is unscrewed from the connecting groove 10, since the transmission air ring 11 is an ordinary rubber air ring, it has elasticity. Under the gravity of the mounting ring 14, the transmission air ring 11 automatically expands, and the mounting ring 14 automatically drives the LED lamp head 15 to be inserted into the probe hole 12.

[0050] When the sound transmission hose 4 is wrapped around the storage head 7, and then the storage head 7 is installed on the storage cover 6, the sound transmission hose 4 is stored in the storage cover 6. Then the outer ring box 9 and the stethoscope head 5 are installed on the storage head 7. At this time, half of the external thread on the storage head 7 is in the storage cover 6, and the other half is in the connecting groove 10. Therefore, the LED lamp head 15 is not completely stored in the outer ring box 9, ensuring that the illumination light is not greatly affected.

[0051] like Figure 4 , Figure 5 As shown, in some embodiments, the sealing sheet 19 is annular and intersects with the illumination hole 12. Adjacent sealing sheets 19 are connected by a connecting arc rod 20. An adjustment groove 18 is provided on the outer side of the slide groove 17, and a paddle 21 that can be inserted into the adjustment groove 18 is provided on the outer side of the sealing sheet 19.

[0052] The sealing plate 19 is moved along the slide groove 17 by the lever 21, and the sealing plate 19 seals the probe hole 12, which is convenient.

[0053] like Figure 4As shown, in some embodiments, the radius of the sealing plate 19 is larger than the radius of the probe hole 12, and the connecting arc rod 20 is disposed along the outer edge of the sealing plate 19.

[0054] This design ensures that the connecting arc rod 20 does not block the search hole 12 and does not affect the light.

[0055] like Figure 5 As shown, in some embodiments, the angle of the adjustment groove 18 is the same as the included angle between the sealing plate 19 and the detection hole 12. With this design, the paddle 21 can be moved from one end of the adjustment groove 18 to the other end, so as to accurately control the opening and closing of the detection hole 12, which is convenient.

[0056] like Figure 6 As shown, in some embodiments, the inside of the storage head 7 is covered with aluminum foil heat insulation roll. This design allows the storage head 7 to be sealed to the outer ring box 9, and when the probe hole 12 is sealed, heat loss can be reduced and preheating efficiency can be improved.

[0057] The above description of the disclosed embodiments enables those skilled in the art to make or use the invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
