Description

Technical Field

[0001] The present application relates to the field of detection equipment, and in particular to a disposable esophageal stethoscope. Background Art

[0002] Among medical application devices, the esophageal stethoscope is used for pathological exploration of the human esophagus and is used in a variety of clinical environments, including operating rooms, emergency departments, intensive care areas, and post-anesthesia care units.

[0003] Existing technologies mainly use separate stethoscopes and thermometers to complete sound monitoring and temperature measurement respectively, which is inconvenient to operate and may not be able to obtain all physiological information in time in some emergency situations. Separate detection will also reduce the accuracy of the detection data. Summary of the Invention

[0004] In order to improve the above problems, the present application provides a disposable esophageal stethoscope.

[0005] The present application provides a disposable esophageal stethoscope that adopts the following technical solution:

[0006] A disposable esophageal stethoscope includes a medical catheter with a signal transmission cable provided therein;

[0007] An acoustic balloon installed in the medical catheter to provide sound reception;

[0008] A temperature probe is installed in the medical catheter to detect the internal temperature of the esophagus.

[0009] By adopting the above technical solution, the medical catheter at one end of the acoustic balloon is inserted into the patient's mouth and extended through the throat into the esophagus. At the same time, the acoustic balloon synchronously collects the sounds in the patient's esophagus and simultaneously detects the heart and lung sounds. The collected sound data is transmitted to an external instrument through a signal transmission cable for data collection and storage. At the same time, the temperature probe detects the body temperature in the patient's esophagus in real time and transmits the detected temperature data to an external instrument. Medical staff can judge the patient's various indicators through the sound data and temperature data obtained from multiple detections, thereby reducing the error rate of judgment.

[0010] Optionally, the medical catheter is further provided with a Luer connector at one end away from the acoustic balloon.

[0011] By adopting the above technical solution, the Luer connector can be used to conveniently connect equipment such as a flushing tube, thereby facilitating flushing of the esophagus.

[0012] Optionally, the end of the acoustic balloon extending into the esophagus is spherical.

[0013] By adopting the above technical solution, the round spherical surface has no edges and corners, which is friendly to the inner wall of the human esophagus. When it comes into contact with the inner wall of the human esophagus, it will not cause scratches or other abnormalities. At the same time, it is also convenient to insert it into the esophagus along the mouth, making it safer for patients.

[0014] Optionally, the surface of the medical catheter is smooth.

[0015] By adopting the above technical solution, the smooth surface of the medical catheter can minimize damage to the esophagus during insertion and removal, improve patient comfort, and reduce foreign body sensation.

[0016] Optionally, the acoustic balloon is provided with a plurality of sound receiving holes.

[0017] By adopting the above technical solution, the sound receiving holes are located in various directions of the acoustic balloon, and can be stably and clearly received, thereby improving the clarity of the sound.

[0018] Optionally, a partition net is provided on the sound receiving hole.

[0019] By adopting the above technical solution, the partition net can reduce the blockage of the sound receiving holes by food residues or mucus attached to the inner wall of the human esophagus, thereby further improving the clarity of the sound reception.

[0020] Optionally, a slidable adsorption ring is further provided on the acoustic balloon; an adsorption portion is provided on the side of the adsorption ring close to the acoustic balloon; a through hole is also provided on the acoustic balloon, and a pull rope is provided in the through hole; one end of the pull rope passes through the through hole and extends out of the medical catheter along the inner wall of the medical catheter, and the other end passes through the through hole and is connected to the adsorption ring.

[0021] By adopting the above technical solution, after one end of the medical catheter equipped with the acoustic balloon is inserted into the human esophagus, in order to ensure the accuracy of the sound reception data, the medical staff pulls the pull rope on the medical catheter at the end outside the human mouth, so that the pull rope provides traction to the adsorption ring, and moves the adsorption ring along the acoustic balloon, so that the adsorption part cleans the food residue or mucus attached to the acoustic balloon, thereby improving the clarity of the sound reception.

[0022] Optionally, an elastic portion is further provided at one end of the acoustic balloon away from the through hole, and the elastic portion is connected to the adsorption ring.

[0023] By adopting the above technical solution, when the pull rope pulls the adsorption ring through the through hole, the adsorption ring moves along the acoustic balloon, stretching the elastic part during the movement, and the elastic part generates a rebound force at the same time. After the pull rope is released, the absorption part is affected by the elastic force of the elastic part and returns to its initial position.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. Insert the medical catheter at one end of the acoustic balloon through the patient's mouth, through the throat and into the esophagus. At the same time, the acoustic balloon collects sounds in the patient's esophagus and simultaneously detects heart and lung sounds. The collected sound data is transmitted to an external instrument via a signal transmission cable for data collection and storage. At the same time, a temperature probe detects the patient's body temperature in the esophagus in real time and transmits the detected temperature data to an external instrument. Medical staff can use the sound and temperature data obtained from multiple detections to judge the patient's various indicators, reducing the error rate of judgment;

[0026] 2. The round spherical surface has no edges and corners, which is friendly to the inner wall of the human esophagus. When in contact with the inner wall of the human esophagus, there will be no scratches or other abnormalities. At the same time, it is also convenient to insert the esophagus through the mouth, making it safer for patients;

[0027] 3. The smooth surface of the medical catheter can minimize the damage to the esophagus during insertion and removal, improve the patient's comfort and reduce the foreign body sensation;

[0028] 4. The sound receiving holes are located in all directions of the acoustic balloon, which can receive the sound stably and clearly, thus improving the clarity of the sound. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Throughout this specification, when a device is said to be "connected" to another device, this includes not only "direct connection" but also "indirect connection" with other elements interposed therebetween. Furthermore, when a device is said to "include" a certain component, unless otherwise stated, this does not exclude the inclusion of other components but rather implies that the device may include other components.

[0037] The following is combined with Figure 1 -Attached Figure 2 , further details of this application are given.

[0038] The embodiment of the present application discloses a disposable esophageal stethoscope.

[0039] A disposable esophageal stethoscope has the function of receiving sound. It needs to extend from the human mouth through the throat to the esophagus to detect abnormalities in the esophagus. It is a disposable device and cannot avoid bacterial infection after use. It can be recycled as medical waste to avoid secondary use and the risk of bacterial infection.

[0040] refer to Figure 1As shown, the disposable esophageal stethoscope includes a medical catheter 1, a signal transmission cable 11 is provided inside, and an instrument connection plug is connected to one end. The medical catheter 1 can adopt a medical-grade hose, which is convenient for providing unstable bends in the throat or esophagus when extending to the patient's mouth, and also reduces the patient's foreign body sensation. The internal signal transmission cable 11 can provide audio data transmission after receiving the sound to provide auscultation, and the instrument connection plug at one end can transmit the received data to an external instrument such as a computer or controller for storage or playback, which can be listened to by medical staff. The medical staff judges the exploration condition of the patient's esophagus based on the received data.

[0041] The acoustic balloon 2 is installed at the end of the medical catheter 1 away from the instrument connection plug, and extends into the patient's esophagus through this end. The acoustic balloon 2 is used to collect sound. The acoustic balloon 2 is soft and slender, which can improve the clarity of heart and lung sounds, collect subtle sounds and form electrical signals, which are transmitted through the signal transmission cable 11.

[0042] The temperature probe 3 is a temperature sensor. The temperature sensing end is installed in the medical catheter 1. The temperature probe 3 extends from the patient's mouth to the esophagus along with the acoustic balloon 2 and the medical catheter 1 to provide detection of the internal temperature of the esophagus, detect the body temperature data in the esophagus or other positions, and use the signal transmission cable 11 to transmit the body temperature data to external computers, controllers and other external instruments, so that the disposable esophageal stethoscope can not only collect and transmit the sound data in the esophagus, but also synchronously collect the body temperature data in the patient's body when collecting the sound data, so that medical staff can perform comprehensive data comparison of multiple sets of data from different detection parts.

[0043] In the figure, the signal transmission cable 11 and the temperature probe 3 are pulled out from the medical catheter 1 for easy observation, and can be inserted into the medical catheter 1 when in use.

[0044] Specifically, the medical catheter 1 at one end of the acoustic balloon 2 is inserted into the patient's mouth and extends through the throat into the esophagus. At the same time, the acoustic balloon 2 collects the sounds in the patient's esophagus and simultaneously detects the sounds of the heart and lungs. The collected sound data is transmitted to an external instrument through a signal transmission cable 11 for data collection and storage. At the same time, the temperature probe 3 detects the body temperature in the patient's esophagus in real time and transmits the detected temperature data to an external instrument. Medical staff can judge the patient's various indicators through the sound data and temperature data obtained from multiple detections, thereby reducing the error rate of judgment.

[0045] Furthermore, the medical catheter 1 is provided with a Luer connector 4 at one end away from the acoustic balloon 2. The Luer connector 4 is mainly a male Luer connector 4 or a male Luer connector 4. The other female Luer connector 4 or the female Luer connector 4 is connected to a flusher. A flushing tube can be extended using the Luer connector 4, and the flushing tube is located in the medical catheter 1. The end of the flushing tube is located at the end of the acoustic balloon 2, and can transport flushing liquids such as physiological saline. The flushing device connected to the female Luer connector 4 or the female Luer connector 4 transports the flushing liquid to the male Luer connector 4 or the male Luer connector 4, and transports it to the acoustic balloon 2 through the flushing tube, so as to flush the patient's esophagus, reduce the impact of food residues or mucus stuck in the esophagus on the collection of sound and body temperature data, and improve the accuracy of the collected data.

[0046] Furthermore, the end of the acoustic balloon 2 that extends into the esophagus is spherical. The spherical surface has no edges and corners and is friendly to the inner wall of the human esophagus. When it comes into contact with the inner wall of the human esophagus, it will not cause scratches or other abnormalities. At the same time, it is also convenient to insert it into the esophagus along the mouth, making it safer for patients.

[0047] Furthermore, the surface of the medical catheter 1 is a rounded surface. The medical catheter 1 is a circular catheter, and the rounded and smooth surface can reduce the friction generated by contact with the inner wall of the human esophagus, which can minimize the damage to the esophagus during insertion and removal, improve the patient's comfort, and reduce the foreign body sensation.

[0048] In some embodiments, a plurality of sound receiving holes 21 are provided on the acoustic balloon 2, and the sound receiving holes 21 are located in various directions of the acoustic balloon 2, so that sounds emitted from various directions, such as heart and lung sounds, can be stably and clearly received, thereby improving the clarity of the sound.

[0049] Furthermore, a partition is provided on the sound receiving hole 21. When the disposable esophageal stethoscope is extended into the patient's esophagus, the acoustic balloon 2 may come into contact with the inner wall of the human esophagus during the extension process. There may be food residues or mucus on the inner wall of the human esophagus. The partition can reduce the possibility of food residues or mucus attached to the inner wall of the human esophagus blocking the sound receiving hole 21, thereby further improving the clarity of the sound reception and reducing the influence of food residues or mucus on the sound reception.

[0050] In some embodiments, reference Figure 2 As shown, the acoustic balloon 2 is also provided with a slidable adsorption ring 22. The annular surface of the adsorption ring 22 is provided with an arc-shaped chamfer, which can reduce the impact on the esophagus when extending into the esophagus. The adsorption ring 22 is provided with an adsorption portion on the side close to the acoustic balloon 2. The adsorption portion can be made of compressed sponge, and the compressed sponge can be embedded in the adsorption ring 22 and cannot be separated from the adsorption ring 22, so as to ensure that it will not be separated from the adsorption ring 22 when performing acoustic detection in the human esophagus.

[0051] The acoustic balloon 2 is also provided with a through hole, in which a pull rope 23 is provided. One end of the pull rope 23 passes through the through hole and extends out of the medical catheter 1 along the inner wall of the medical catheter 1, and the other end passes through the through hole and is connected to the adsorption ring 22, so that when the medical staff pulls the pull rope 23 at one end of the medical catheter 1 outside the human mouth, the pull rope 23 will move the adsorption ring 22 along the acoustic balloon 2, so that the adsorption part absorbs the mucus on the sound receiving hole 21 or the partition net on the surface of the sound receiving hole 21, or wipes the food residue attached to the sound receiving hole 21 or the partition net, so as to ensure the normal reception of the sound receiving hole 21 and improve the accuracy of the sound reception data.

[0052] Among them, at least two pulling ropes 23 can be provided, so that when pulling, at least two force-bearing points of the adsorption ring 22 are pulled synchronously to ensure force balance. The figure shows only one pulling rope 23.

[0053] Specifically, after one end of the medical catheter 1 equipped with the acoustic balloon 2 is inserted into the human esophagus, in order to ensure the accuracy of the sound reception data, the medical staff pulls the pull rope 23 on the medical catheter 1 located at one end outside the human mouth, so that the pull rope 23 provides traction to the adsorption ring 22, and moves the adsorption ring 22 along the acoustic balloon 2, so that the adsorption part cleans the food residue or mucus attached to the acoustic balloon 2, thereby improving the clarity of the sound reception.

[0054] Furthermore, an elastic portion 24 is provided at one end of the acoustic balloon 2 away from the through hole, and the elastic portion 24 is connected to the adsorption ring 22. The elastic portion 24 can be made of several elastic and medical-grade plastic ropes. After the elastic portion 24 is connected to the adsorption ring 22, it provides a reset effect on the adsorption ring 22. When the pull rope 23 pulls the adsorption ring 22 through the through hole, the adsorption ring 22 moves along the acoustic balloon 2. During the movement, the elastic portion 24 is stretched, and at the same time, the elastic portion 24 generates a rebound force. When the absorption portion absorbs mucus or removes food residues, the medical staff slowly loosens the pull rope 23, so that the absorption portion is affected by the elastic force of the elastic portion 24 and returns to its initial position, so as to facilitate the next absorption of mucus and cleaning of food residues, and at the same time will not affect the normal operation of the sound collection process.

[0055] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
