Description

Technical Field

[0001] The utility model relates to the technical field of stethoscopes, in particular to a durable stethoscope. Background Art

[0002] A stethoscope is a medical device used to listen to internal body sounds, such as heartbeat, lung and blood flow sounds. It was invented by French physician Rene Lannec in 1816. A stethoscope usually consists of earplugs, earrings, tubes and a pleural head, which is the part placed on the patient's body and can be a round flat plate to capture the sound. Modern stethoscopes usually have a dual-head design, one end is a large, flat diaphragm for low-frequency sounds, and the other end is a bell-shaped part for high-frequency sounds. Doctors, nurses and other health care professionals use stethoscopes to assess the health of a patient's heart, lungs and other organs. It is an indispensable tool in diagnosing and monitoring a patient's condition. As technology develops, electronic stethoscopes have also emerged that can amplify sound and convert sound data into digital signals for analysis.

[0003] At present, hospitals still mainly use stethoscopes for physical auscultation, especially doctors on duty in emergency rooms, who use stethoscopes more and more frequently. The pleural head of the stethoscope will contact different patients and the skin / underwear of different patients. In this process, there are no blocking or disinfection measures for the pleural head, which may cause infection for skin diseases or other more easily transmitted diseases.

[0004] Therefore, a durable stethoscope is proposed to solve or alleviate the above problems. Utility Model Content

[0005] The utility model aims to solve the shortcomings in the prior art and provides a durable stethoscope.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A durable stethoscope includes a pleural head, which includes a connecting tube, and a large expansion head and a small expansion head fixedly connected at both ends thereof. The outer ring of the connecting tube is provided with a ring that can be displaced along the length of the tube, and the ring can be positioned at any position in its displacement process. A clamping space is formed between the ring and the large expansion head for accommodating the edge of a film mounted on the outside of the large expansion head.

[0008] Preferably, the outer side of the connecting pipe is provided with an external thread, and the inner ring of the collar is provided with an internal thread threadably connected to the external thread.

[0009] Preferably, the collar is provided with a resisting piece that resists against the large expansion head.

[0010] Preferably, a groove is formed in the outer ring of the collar. The abutting member includes a rotating head rotatably connected in the groove, a connecting rod fixedly connected thereto, and a soft head fixedly connected to the connecting rod and adapted to abut against the large expansion tube head.

[0011] Preferably, the bottom of the soft head is in a spherical arc shape.

[0012] Preferably, the soft head is made of rubber.

[0013] Preferably, it further includes a U-shaped tube, ear rings fixedly connected to both ends thereof, earplugs fixedly connected to the ear rings, and a flexible tube fixedly connected to the U-shaped tube. A connection hole is formed in the connecting tube, and one end of the flexible tube away from the U-shaped tube is fixedly connected in the connection hole.

[0014] The utility model has the following beneficial effects:

[0015] During the use of the stethoscope of the utility model, medical staff only need to gently hold the ear rings and pull them outwards slightly, and the U-shaped tube will deform due to the force. This action causes the distance between the two ear rings to naturally expand, and then sufficient space is formed for medical staff to easily put their heads into it. After the head enters this space, by manually adjusting the position of the earplugs, ensure that they are comfortably placed in the ears, and then complete the process of receiving the sound of the stethoscope.

[0016] Medical staff need to take a fitting film, lay it flat on the outside of the large expansion tube head, and carefully fix the film edge in the clamping space between the large expansion tube head and its matching collar. Then, a manual action is carried out. Gently rotate the abutting member, and its rotating head will deflect in the groove. This change acts on the soft head through the connecting rod, causing the soft head to tilt and move towards the connecting tube along with the connecting rod, and finally abut against the back surface of the large expansion tube head. The friction generated by this contact firmly adheres the film to the surface of the large expansion tube head to maintain its integrity and stable position.

[0017] When there are differences in the film size, medical staff can also manually adjust the positions of the outer-threaded and inner-threaded collars relative to the connecting tube to ensure that the center distance of the abutting member always appropriately contacts the film edge, ensuring clear sound conduction without interference during the diagnosis process. Then, auscultation is started through the configured pleural head, and an accurate and delicate sound capture experience will be enjoyed.

[0018] After completing one auscultation, before facing the next patient, medical staff only need to remove the used film and replace it with a new one, and then perform the above-mentioned quick and simple device adjustment steps again. This not only greatly reduces the number of direct contacts between the pleural head and the patient's skin, thereby reducing the risk of cross-infection between patients, ensuring the auscultation quality and medical safety, but also enhances the durability and lifespan of the stethoscope, avoiding the need for frequent replacement of accessories.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0023] A durable stethoscope, as Figure 1 shown, includes a U-shaped tube 1, earrings 2 fixedly connected to both ends thereof, earplugs 3 fixedly connected to the earrings 2, and a hose 4 and a pleural head 5 fixedly connected to the U-shaped tube 1.

[0024] As Figure 2 shown, the pleural head 5 includes a connecting tube 502, and a large expansion tube head 501 and a small expansion tube head 503 fixedly connected to both ends thereof. A connecting hole 5021 is provided on the connecting tube 502. One end of the hose 4 far from the U-shaped tube 1 is fixedly connected to the connecting hole 5021. An outer ring of the connecting tube 502 is provided with a sleeve ring that can be displaced along the tube length direction. An external thread is provided on the outer side of the connecting tube 502, and an internal thread threadedly connected to the external thread is provided in the inner ring of the sleeve ring 504, so that the sleeve ring can be positioned at any position during its displacement process.

[0025] A clamping space for accommodating the edge of a film sleeved on the outside of the large expansion head 501 is formed between the ferrule and the large expansion head 501. The ferrule 504 is provided with a resistance member for resisting the large expansion head 501. The outer ring of the ferrule 504 is provided with an embedding groove 5041. The resistance member includes a swivel head 5042 rotatably connected in the embedding groove 5041, a connecting rod 5043 fixedly connected thereto, and a soft head fixedly connected to the connecting rod 5043 and used for resisting the large expansion head 501. The bottom of the soft head 5044 is a spherical arc surface, and the soft head 5044 is made of rubber.

[0026] When the medical staff uses the utility model, they only need to hold the earrings 2 and pull them outwards, so that the U-shaped tube 1 is deformed under the force exerted by the medical staff, so that the distance between the earrings 2 on both sides is expanded, so that a space is formed between the two for the medical staff to put their heads in. After putting in, the medical staff manually adjusts and inserts the earplugs 3 into their ears to complete the listening of the stethoscope sound. Before the medical staff actually listens to the stethoscope, they need to put a film on the outside of the large expansion tube head 501, and cover the edge of the film to the clamping space between the large expansion tube head 501 and the ring 504, and then rotate the abutment to make the rotating head 5042 deflect in the embedding groove 5041. When deflecting, the rotating head 5042 will drive the soft head 5044 to deflect together through the connecting rod 5043, so that the soft head 5044 follows the connecting rod When 5043 deflects and moves toward the direction of the connecting tube 502, it can contact with the back of the large expansion head 501 and generate friction. At this time, the friction will act on the edge of the film, so that the film can remain close to the large expansion head 501. When the size of the film is different, the medical staff can also manually use the external thread and the internal thread to adjust the position of the ring 504 on the connecting tube 502, so as to ensure that the distance between the center of the circle of the abutment and the edge of the film is always kept in contact. Then the medical staff will use the pleural head 5 for auscultation. Before auscultating the next patient, they only need to remove the film and repeat the above operation. In this way, the stethoscope can also reduce the number of times the pleural head 5 directly contacts the patient. On the one hand, it can avoid the possibility of cross-disease between patients, and on the other hand, it can also make the stethoscope more durable and long-lasting.
