Description

Technical Field

[0001] The present invention relates to the technical field of medical auxiliary devices, and more particularly to an ultrasonic examination auxiliary device. Background Art

[0002] Cardiac ultrasound is a method of evaluating the morphology, spatial relationship, activity of various cardiac structures, and the blood flow status of cardiac chambers. It is of great importance for the examination of congenital heart disease, acquired heart disease and their complications. Ultrasound testing can be divided into conventional transthoracic cardiac ultrasound and transesophageal echocardiography. For patients affected by factors such as obesity, emphysema, and chest deformity, transthoracic echocardiography cannot obtain satisfactory examination results. Transesophageal echocardiography (TEE) provides a good diagnostic basis for such patients, so it has unique advantages in ultrasound testing.

[0003] The existing process of transesophageal ultrasound detection is mainly as follows: use an appropriate amount of anesthetic spray to spray the patient's pharynx and let the patient swallow a little, the esophageal mucosa and pharyngeal mucosa surface will be anesthetized, the patient takes the left side lying position, the machine probe is switched to the esophageal probe, the esophageal probe and the front surface of the tube body are evenly coated with coupling agent, the top of the probe is tilted forward slightly in an arc shape, the patient is asked to open his mouth and stick out his tongue, the esophageal probe is inserted into the patient's esophagus through the mouth, and a standard interface scan is performed.

[0004] From the analysis of the existing testing process, it can be seen that the main problems are as follows: the patient needs to open his mouth by himself and keep it open for 10-20 minutes. During this process, the probe needs to move and scan continuously in the patient's mouth, and the patient's oral muscles are not supported and easily fatigued, which increases the patient's pain during the examination; at the same time, the method of anesthesia for the patient's pharynx is external spray, and the patient needs to swallow a small amount of anesthetic by himself. The anesthetic spray applied in this process is difficult to accurately reach the best position in the patient's mouth, resulting in reduced efficacy and uneven application of the drug. In addition, the patient's control of the swallowing action is uncertain, which may cause insufficient anesthetic application or excessive anesthetic administration. Therefore, in transesophageal cardiac ultrasound testing, auxiliary devices that assist the patient's mouth to open and provide support, as well as spray devices that help the anesthetic spray penetrate into the patient's pharynx and evenly apply the drug are currently needed.

DETAILED DESCRIPTION

[0026] The technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The ultrasonic inspection auxiliary device involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0027] Reference Figure 1 The present invention provides an ultrasonic examination auxiliary device, comprising a holding component 1, a locking component 2 is installed inside the holding component 1, an expansion component 3 is installed on the left side of the holding component 1, a spray component 4 is installed inside the expansion component 3, and an esophageal probe 5 is installed inside the spray component 4;

[0028] In this embodiment, it should be specifically explained that: the holding component 1 is the part for medical staff to hold, and the structure of the expansion component 3 is expanded to the surroundings by pressing the locking component 2, so as to open and support the oral cavity, and the spray component 4 is placed in the patient's mouth, and the spray component 4 sprays anesthetic drugs into the patient's throat. A hole is opened in the center of the spray component 4, and the esophageal probe 5 passes through the hole of the spray component 4, enters the patient's oral cavity and penetrates into the esophagus, so as to perform transesophageal cardiac ultrasound detection.

[0029] The main difference between this embodiment and the prior art is that this embodiment adopts a self-locking mechanism and a rocker mechanism to achieve the opening of the patient's mouth and pharyngeal anesthesia during transesophageal ultrasound testing, specifically the expansion component 3 and the spray component 4;

[0030] The above structure is the main structure of this embodiment, which solves the problem that the patient's mouth needs to be kept open by itself or manually opened by medical staff during transesophageal cardiac ultrasound testing. Secondly, it solves the problem that anesthetic drugs do not penetrate deeply into the patient's throat and overflow before spraying. The esophageal probe 5 is an existing structure, and the specific structure and connection method of the esophageal probe 5 are not described in detail in this embodiment.

[0031] Reference Figure 2 and Figure 3 The holding component 1 includes a component housing 101, and an anti-slip layer 102 is installed on the outer side of the component housing 101. The locking component 2 includes a push rod 202, and a locking button 201 is installed on one end of the push rod 202. The push rod 202 penetrates from the end of the component housing 101 close to the locking button 201 and passes out from the end of the component housing 101 away from the locking button 201. The part of the push rod 202 located inside the holding component 1 is installed with a positioning slider 203, and a guide rail 2031 is opened on the positioning slider 203. The component housing 101 is away from the locking button 201. A swing rod 204 is installed at one end of the button 201, and a fixed shaft 2042 is installed at the end of the swing rod 204 away from the positioning slider 203. The fixed shaft 2042 is fixed inside the component housing 101, and a movable pulley 2041 is installed at the end of the swing rod 204 away from the fixed shaft 2042. The movable pulley 2041 contacts the inside of the guide rail 2031. A telescopic spring 205 is installed at the end of the positioning slider 203 close to the swing rod 204, and the end of the telescopic spring 205 away from the positioning slider 203 is connected to the inner wall of the component housing 101.

[0032] In this embodiment, it needs to be specifically explained that: when the locking component 2 is in a pressed state, the movable pulley 2041 is located at the end of the guide rail 2031 closest to the locking button 201, the telescopic spring 205 is in a compressed state and has not reached the compression limit, and the positioning slider 203 is in a position inside the component housing 101 away from the locking button 201. At this time, the locking button 201 is pressed and then released, and the movable pulley 2041 will slide downward along the inside of the guide rail 2031, and the telescopic spring 205 loses its resistance and releases pressure. The telescopic spring 205 stretches and pulls the push rod 202 to move in the direction of the locking button 201. At the same time, the telescopic spring 205 pushes the positioning slider 203 inside the component housing 101 to a position close to the locking button 201, and the movable pulley 2041 reaches the end of the guide rail 2031 farthest from the locking button 201.

[0033] Reference Figure 4 , Figure 5 and Figure 6A driving block 304 is installed at the end of the push rod 202 away from the component housing 101, and a pushing block 307 is installed inside the driving block 304. A sliding groove 3071 is opened inside the pushing block 307, and the number of sliding grooves 3071 is three. The expansion component 3 includes a fixed plate 301 and an expansion block 303. The number of expansion blocks 303 is four, and an inlet channel 308 is opened between the four expansion blocks 303. A rocker arm 305 is installed on the outside of the expansion block 303, and a swing shaft 306 is installed in the middle part of the rocker arm 305. The swing shaft 306 is fixed inside the fixed plate 301. A sliding wheel 3051 is installed at the end of the rocker arm 305 away from the expansion block 303, and the sliding wheel 3051 is located inside the sliding groove 3071. A flexible connecting block 302 is installed at the end of the driving block 304 away from the push rod 202, and the flexible connecting block 302 is connected to the expansion block 303 closest to the driving block 304.

[0034] In this embodiment, it should be specifically explained that: the four expansion blocks 303 in the initial state are in contact with each other. At this time, the function of the flexible connection block 302 is that when the push rod 202 continues to be squeezed in the direction of the driving block 304, the push rod 202 can still continue to move in this direction to a certain extent, so that the telescopic spring 205 can continue to be compressed for a distance in the compressed state, and the positioning slider 203 can continue to move a distance in the direction of the telescopic spring 205, so that the guide rail 2031 can move along the moving pulley 2041. When the user presses the lock button 201 and releases it, the push rod 202 moves in the direction away from the driving block 304, pulling the driving block 304 away from the expansion block 3 03, the driving block 304 drives the flexible connection block 302 to move, the flexible connection block 302 drives the expansion block 303 connected thereto to move in the same direction, the driving block 304 drives the pushing block 307 to move away from the expansion block 303, the rocker arm 305 rotates with the rocking shaft 306 as the rotation center, so that the sliding wheel 3051 slides inside the sliding groove 3071, and the rotation of the rocker arm 305 drives the remaining three expansion blocks 303 to expand upward, downward and away from the driving block 304 respectively, so that the oral cavity of the patient being tested is supported and opened by the expansion block 303, and at the same time, the device can maintain the state unchanged under the action of the positioning slider 203 and the swing rod 204.

[0035] Reference Figure 7The spray assembly 4 includes a spray pipe 401, an injection plug 403 is installed at one end of the spray pipe 401 close to the fixed plate 301, a medicine delivery piston 405 is installed at a position close to the injection plug 403 inside the spray pipe 401, a medicine delivery push block 406 is installed at one end of the medicine delivery piston 405 away from the injection plug 403, a valve pull rod 407 is installed at one end of the medicine delivery push block 406 away from the medicine delivery piston 405, there are two valve pull rods 407, a pull rod center axis 408 is installed between the two valve pull rods 407, a medicine delivery valve 409 is installed at one end of the valve pull rod 407 away from the medicine delivery push block 406, a medicine discharge head 410 is installed at one end of the spray pipe 401 away from the injection plug 403, and a medicine storage cavity 4011 is opened between the medicine discharge push block 406 and the medicine discharge head 410.

[0036] In this embodiment, it is necessary to specifically explain that: the medicine storage cavity 4011 is filled with medicine, a plurality of holes are provided on the medicine discharging head 410, and a protrusion block having the same size as the holes on the medicine discharging head 410 is provided on the medicine discharging valve 409. In the initial state, the medicine discharging valve 409 is in contact with the medicine discharging head 410, and the protrusion on the medicine discharging valve 409 closes the holes of the medicine discharging head 410, so that the medicine in the medicine storage cavity 4011 will not overflow. When the valve pull rod 407 close to the medicine discharging push block 406 moves toward the direction of the medicine discharging head 410, the valve pull rod 407 is 7 will drive another valve pull rod 407 to move towards the direction of the medicine releasing push block 406 through the rotation of the pull rod central axis 408, thereby driving the medicine releasing valve 409 to move away from the medicine dispensing head 410, and the hole of the medicine dispensing head 410 is opened. At this time, the user presses the injection plug 403, and the injection plug 403 pushes the medicine delivery piston 405 to move towards the medicine dispensing head 410. The movement of the medicine delivery piston 405 will compress the space of the medicine storage chamber 4011, and the medicine in the medicine storage chamber 4011 will be squeezed and sprayed to the outside through the holes on the medicine dispensing head 410.

[0037] Reference Figure 8 The spray assembly 4 includes a bracket 402, which is fixed to the back of the fixing plate 301, and a medicine release button 404 is installed on the outer side of the injection plug 403.

[0038] In this embodiment, it is necessary to specifically explain that: the bracket 402 fixes the spray tube 401 on the expansion component 3, and when the user presses the injection plug 403 and the medicine release button 404 at the same time, pressing the medicine release button 404 will push the medicine release push block 406 to move toward the direction of the medicine release valve 409, and the medicine release push block 406 will push the valve pull rod 407, thereby causing the medicine release valve 409 to move toward the direction of the medicine release push block 406, thereby opening the hole of the medicine outlet head 410.

[0039] Working principle of the present invention:

[0040] The main problem solved by this embodiment is that the device is provided with a rocker arm 305 and a push block 307, and the physical properties of the rocker arm and the spring are used to make the push block 307 driven when the push rod 202 pushes or pulls the drive block 304, and the rocker arm 305 is pushed and rotated by the push block 307, so that the rocker arm 305 drives the four expansion blocks 303 to contract inward or expand outward, so that the user can control the expansion block 303 to contract and expand to support the patient's oral cavity by pressing the lock button 201, thereby solving the problem that in transesophageal cardiac ultrasound detection, the patient needs to open his mouth by himself or the medical staff needs to open the mouth manually, which is inconvenient and difficult to maintain for a long time;

[0041] Secondly, by providing a medicine release valve 409 and a medicine outlet head 410, through a pulley and piston structure, the user can press the medicine release button 404 while pressing the injection plug 403, thereby closing and opening the hole on the medicine outlet head 410, thereby solving the problem of medicine overflowing before administering the medicine deep in the patient's throat.

[0042] The specific steps are as follows: in the initial state, the expansion blocks 303 are in contact with each other, at this time, the movable pulley 2041 is located at one end of the guide rail 2031 close to the locking button 201, the positioning slider 203 is in a position inside the component housing 101 away from the locking button 201, the telescopic spring 205 is in a compressed state, the injection plug 403 and the medicine release button 404 are both located outside the spray pipe 401, the medicine release valve 409 is in contact with the medicine discharge head 410, and the medicine release valve 409 blocks the hole of the medicine discharge head 410.

[0043] When the user starts to test the patient, he first holds the holding component 1, puts the expansion component 3 into the mouth of the person being tested, presses the locking button 201 and then releases it, and the pushing rod 202 pushes the positioning slider 203 in the direction away from the locking button 201, and the telescopic spring 205 is further compressed for a period of time, and the pushing rod 202 pushes the driving block 304, and the driving block 304 squeezes the flexible connecting block 302, so that the driving block 304 moves a distance in the direction of the flexible connecting block 302. At this time, the movement of the positioning slider 203 will cause the moving pulley 2041 to slide downward along the inside of the guide rail 2031, and the swing rod 204 changes its position by swinging under the fixation of the fixed rotating shaft 2042, and the telescopic spring 205 loses its blocking and releases pressure. The telescopic spring 205 stretches and drives the pushing rod 202 to move in the direction of the locking button 201. At the same time, the telescopic spring 205 pushes the positioning slider 203 inside the component housing 101 to a position close to the locking button 201, and the moving slider When the wheel 2041 reaches the end of the guide rail 2031 farthest from the locking button 201, the push rod 202 moves in the direction away from the driving block 304, pulling the driving block 304 to move in the direction away from the expansion block 303, and the driving block 304 drives the flexible connection block 302 to move, and the flexible connection block 302 drives the expansion block 303 connected thereto to move in the same direction, and the driving block 304 drives the pushing block 307 to move in the direction away from the expansion block 303, and the rocker arm 305 rotates with the rocking shaft 306 as the rotation center, so that the sliding wheel 3051 slides inside the sliding groove 3071, and the rotation of the rocker arm 305 drives the remaining three expansion blocks 303 to expand upward, downward and away from the driving block 304 respectively, so that the oral cavity of the patient being tested is supported and opened by the expansion block 303, and at the same time, the device can maintain the state unchanged under the action of the positioning slider 203 and the swing rod 204, at this time, the moving pulley 2041 is stationary, and the telescopic spring 205 is in an extended state.

[0044] The medicine dispensing head 410 is inserted into the deep of the patient's oral cavity through the throat inlet channel 308. The user presses the injection plug 403 and the medicine releasing button 404 at the same time. The medicine releasing button 404 pushes the medicine releasing push block 406 to move toward the medicine releasing valve 409. The medicine releasing push block 406 pushes the valve pull rod 407 near the medicine releasing push block 406 to move toward the medicine releasing valve 409. The valve pull rod 407 drives another valve pull rod 407 through the rotation of the pull rod center axis 408. The medicine releasing valve 409 moves toward the direction close to the medicine releasing push block 406, thereby driving the medicine releasing valve 409 to move away from the medicine dispensing head 410, and the hole of the medicine dispensing head 410 is opened. At this time, the user continues to press the injection plug 403, and the injection plug 403 pushes the medicine delivery piston 405 to move toward the direction of the medicine dispensing head 410. The movement of the medicine delivery piston 405 compresses the space of the medicine storage chamber 4011, and the medicine in the medicine storage chamber 4011 will be squeezed and sprayed to the outside through the holes on the medicine dispensing head 410.

[0045] Finally, the esophageal probe 5 is sent into the patient's esophagus through the channel opened in the center of the spray component 4 for ultrasonic detection.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
