Description

Technical Field

[0001] The present invention relates to the technical field of ultrasonic probes, in particular to a medical imaging diagnosis ultrasonic probe device. Background Art

[0002] The physical principle of ultrasound is to use the acoustic characteristic of resistance, and air can effectively block the propagation of ultrasound. However, on the surface of human skin, due to the different inspection areas, there is a certain amount of air between the probe and the uneven skin surface, which interferes with the use of ultrasound. During the ultrasound scan, the doctor needs to apply a gel-like coupling agent to the part to be inspected to lubricate, reduce acoustic resistance, and improve image display. After the inspection, a large amount of paper towels are needed to wipe it, which causes inconvenience to the patient and also causes waste.

[0003] Currently, when performing ultrasonic examination on the human body, if the examination area is large, medical workers need to apply coupling agent multiple times, and then they need to reposition the target area, which increases the difficulty of operation for medical workers and increases their workload.

[0004] like Figure 1 As shown, the probe can be summarized as an operating part 1 and a probe part 2. When the probe moves back and forth, it will slide over a large amount of skin. The ultrasonic probe device in the present invention can automatically apply the coupling agent at the forward end during the movement of the probe back and forth, thereby ensuring the coupling effect and recovering the residual coupling agent in the surrounding area, thereby reducing the overall usage of the coupling agent, reducing the discomfort of the person being tested due to the coupling agent, and reducing the need for wiping at a later time.

[0005] Therefore, in order to solve the above problems, a medical imaging diagnosis ultrasound probe device is proposed. Summary of the invention

[0006] The purpose of the present invention is to provide a medical imaging diagnostic ultrasound probe device, which can automatically apply coupling agent to the forward end during the forward and backward movement of the probe, thereby ensuring the coupling effect and recovering the residual coupling agent in the surrounding area, reducing the overall usage of the coupling agent, reducing the discomfort of the person being tested due to the coupling agent, and reducing the need for subsequent wiping.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a medical imaging diagnostic ultrasound probe device, comprising a kit and a controller, wherein the kit can be sleeved on the outside of the probe part, an acceleration sensor capable of obtaining the moving direction of the probe is arranged in the kit, two acceleration sensors are provided, which are respectively used to sense the displacement in the front and rear directions, an extrusion tube is fixedly connected to the inside of the kit, and the front and rear ends of the extrusion tube are respectively connected with a front tube and a rear tube, the front tube and the rear tube are respectively arranged on the inside of the front and rear ends of the kit, and the bottom ends of the front tube and the rear tube are connected with a discharge pipe, after the acceleration sensor obtains the displacement of the probe, the coupling agent is applied to the forward end through the discharge pipe, and applying the coupling agent to the forward end can effectively increase the coupling effect while reducing the amount of coupling agent used.

[0008] The device also includes a pump-out tube, the inner side of which is slidably connected to a second piston, the inner side of the bottom end of the pump-out tube is connected to a one-way tube, and the coupling agent is placed in front of the pump-out tube through the one-way tube. The inner side of the bottom end of the pump-out tube is connected to a second one-way valve, and the output end of the second one-way valve is connected to the extrusion tube. When the second piston moves downward, the coupling agent placed in front of the pump-out tube moves toward the extrusion tube.

[0009] A plug is slidably connected to the inner side of the extrusion tube, an electric push rod is fixedly connected to the inner side of the kit, and the movable end of the electric push rod is fixedly connected to the plug via a connecting piece. When the plug is in the middle position of the extrusion tube, the second one-way valve is in a blocked state. When the plug is at the front end of the extrusion tube under the action of the electric push rod, the second one-way valve is connected to the rear tube. At this time, the discharge pipe at the rear end can discharge the coupling agent. When the plug is at the rear end of the extrusion tube under the action of the electric push rod, the second one-way valve is connected to the front tube. At this time, the discharge pipe at the front end can discharge the coupling agent.

[0010] Under the above settings, the present invention is operated by operating the operating part of the probe, and the kit of the present invention is put on the outside of the probe part. The connection mode of the kit and the probe part can be a detachable mode such as a snap connection. Because the probe will slide over a large amount of skin when moving forward and backward, at this time, it is necessary to replenish the coupling agent in time to achieve the detection effect. The ultrasonic probe device of the present invention can automatically realize the application of the coupling agent at the forward end during the movement of the probe forward and backward to ensure the coupling effect;

[0011] When the probe moves forward, the acceleration sensor responsible for the forward direction will sense the acceleration change. At this time, the controller will control the electric push rod to retract. At this time, the plug is at the rear end of the extrusion tube under the action of the electric push rod, and the second one-way valve is connected to the front tube. At this time, the discharge pipe at the front end can discharge the coupling agent to fill the air between the probe and the skin.

[0012] When the probe moves backward, the acceleration sensor responsible for the backward direction will sense the acceleration change. At this time, the controller will control the electric push rod to extend. At this time, the plug is at the front end of the extrusion tube under the action of the electric push rod, and the second one-way valve is connected to the rear tube. At this time, the exhaust pipe at the rear end can discharge the coupling agent to fill the air between the probe and the skin;

[0013] As a preferred medical imaging diagnostic ultrasound probe device of the present invention, a U-shaped tube is fixedly connected to the inner side of the kit, and the bottom end of the U-shaped tube is connected to two sliders, and the two sliders can be flush with the left and right sides of the probe part, and grooves are provided at the front and rear ends of the sliders, and a suction hole is provided on the inner side of the groove, and after the probe slides over the skin in the front and rear directions, excess coupling agent will be squeezed into the groove.

[0014] As a preferred medical imaging diagnostic ultrasound probe device of the present invention, the outer side of the pump-out tube is fixedly connected to a recovery tube, the inner side of the recovery tube is also slidably connected to a second piston, the bottom end of the recovery tube is connected to a reflux tube, the reflux tube is unidirectionally connected, the other end of the reflux tube is connected to a U-shaped tube, and when the second piston in the recovery tube moves upward, excess coupling agent can be sucked into the recovery tube.

[0015] Under the above settings, when the probe is used, a little coupling agent can be pre-adhered to the surface before use, because after the probe slides over the skin in the front-back direction, the excess coupling agent will squeeze into the groove. In order to achieve the recovery of the residual coupling agent in the surrounding area, reduce the overall usage of the coupling agent, reduce the discomfort caused by the coupling agent to the person being tested, and reduce the subsequent wiping situation, the second piston in the recovery tube of the present invention moves upward, and the groove is used to temporarily store the coupling agent. The excess coupling agent will be concentrated in the groove and enter the recovery tube through the extraction hole, the U-shaped tube, and the reflux tube to achieve recovery;

[0016] As a preferred medical imaging diagnostic ultrasound probe device of the present invention, the inner sides of the pump-out tube and the recovery tube are both provided with springs for achieving a reset effect. In the initial state, the second piston in the pump-out tube is at the bottom end of the pump-out tube, and the second piston in the recovery tube is at the middle position of the recovery tube.

[0017] As a preferred medical imaging diagnostic ultrasound probe device of the present invention, the bottom ends of the pump outlet tube and the recovery tube are connected through a first one-way valve, and the coupling liquid recovered in the recovery tube can enter the inner side of the bottom end of the pump outlet tube. The input resistance of the first one-way valve is greater than that of the electric exhaust valve. When exhausting, the gas is preferentially discharged through the electric exhaust valve.

[0018] As a preferred medical imaging diagnostic ultrasound probe device of the present invention, the bottom end of the recovery tube is also connected to an electric exhaust valve, and a gas-liquid analysis component is also provided at the bottom end of the electric exhaust valve for analyzing whether the place is coupling liquid or gas. The gas-liquid analysis component includes a second motor fixed on the inner side of the recovery tube, and a rotating plate is fixedly connected to the end of the main shaft of the second motor. The rotating plate rotates on the inner side of the bottom end of the recovery tube. A speed sensor is provided on the main shaft of the second motor. The speed difference caused by the density difference between the gas and the liquid is used to determine whether the place is gas phase or liquid phase. When it is liquid phase, the second piston in the recovery tube is moved downward, and the second piston in the pump out tube is moved upward, so that the coupling liquid enters a new use cycle again.

[0019] As a preferred medical imaging diagnostic ultrasound probe device of the present invention, the top ends of the recovery tube and the pump-out tube are connected to external joints through pipelines, and the device also includes a bottle body, and the bottom end and the middle position of the bottle body are respectively connected to the first suction tube and the second suction tube, and the first suction tube and the second suction tube are connected to the same internal joint, and the internal joint can be snapped into the external joint. After snapping, the first suction tube is only connected to the inner side of the top end of the recovery tube, and the second suction tube is only connected to the inner side of the top end of the pump-out tube.

[0020] As a preferred medical imaging diagnostic ultrasound probe device of the present invention, the bottom end of the bottle body is slidably connected to a first piston, and the first piston divides the bottom end of the bottle body into two upper and lower spaces. The upper space is connected to the second suction tube, and the lower space is connected to the first suction tube. When the first piston moves downward, the second piston in the pump-out tube moves upward and realizes the pre-positioning of the coupling agent through the one-way tube. When the coupling agent is pre-positioned, the input end of the one-way tube is in the boxed coupling agent. When the first piston moves upward, the second piston in the pump-out tube moves downward and discharges the coupling agent through the second one-way valve and the front tube.

[0021] In the present invention, the coupling agent collected by the recovery tube is only used in the current exploration, and a new set needs to be replaced when it is used next time;

[0022] When the second piston in the recovery pipe moves downward and the second piston in the pump-out pipe moves upward, that is, when the first piston moves downward, the coupling liquid recovered in the recovery pipe can enter the pump-out pipe through the first one-way valve, so that the coupling liquid enters a new use cycle again, thereby reducing the overall use amount of the coupling liquid;

[0023] In the present invention, since air is sucked into the inner side of the recovery pipe during the recovery process, the present invention determines whether it is a gas phase or a liquid phase at the bottom of the recovery pipe by the speed difference caused by the density difference between gas and liquid. When it is a liquid phase, the second piston in the recovery pipe is moved downward, and the second piston in the pump-out pipe is moved upward, so that the coupling liquid enters a new use cycle again. When it is a gas phase, the controller controls the electric exhaust valve to open, and the excess gas is discharged from the recovery pipe, thereby realizing the coupling agent supply in the entire detection process.

[0025] The rotation of the first motor will drive the screw to rotate, the rotation of the screw will drive the slide plate to move up or down, the movement of the slide plate will drive the first piston to move up or down, thereby realizing the above-mentioned pumping and recovery operations.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] 1. A medical imaging diagnostic ultrasound probe device, the present invention is operated by operating the operating part of the probe, the kit of the present invention is put on the outside of the probe part, the connection mode of the kit and the probe part can be a detachable mode such as a snap connection, because the probe will slide over a large amount of skin when moving forward and backward, at this time, it is necessary to replenish the coupling agent in time to achieve the detection effect, the ultrasound probe device of the present invention can automatically realize the application of coupling agent at the forward end during the movement of the probe forward and backward to ensure the coupling effect, when the probe moves forward, the acceleration sensor responsible for the forward direction will sense the acceleration change, at this time, the controller will control the electric push rod to retract, At this time, the plug is at the rear end of the extrusion tube under the action of the electric push rod, and the second one-way valve is connected to the front tube. At this time, the discharge pipe at the front end can discharge the coupling agent to fill the air between the probe and the skin. When the probe moves backward, the acceleration sensor responsible for the backward direction will sense the acceleration change. At this time, the controller will control the electric push rod to extend. At this time, the plug is at the front end of the extrusion tube under the action of the electric push rod, and the second one-way valve is connected to the rear tube. At this time, the discharge pipe at the rear end can discharge the coupling agent to fill the air between the probe and the skin. Applying the coupling agent at the forward end can effectively increase the coupling effect while reducing the amount of coupling agent used.

[0028] 2. In this medical imaging diagnostic ultrasound probe device, after the probe slides over the skin in the front-to-back direction, excess coupling agent will squeeze into the groove.

Excess coupling agent will be concentrated in the groove and enter the recovery tube through the suction hole, the U-shaped tube, and the reflux tube for recovery.

[0029] 3. In a medical imaging diagnostic ultrasound probe device, the coupling agent collected in the recovery tube is only used in the current exploration. When it is used next time, a new kit needs to be replaced. When the second piston in the recovery tube moves downward and the second piston in the pump-out tube moves upward, that is, when the first piston moves downward, the coupling liquid recovered in the recovery tube can enter the pump-out tube through the first one-way valve, so that the coupling liquid enters a new use cycle again, thereby reducing the overall usage of the coupling liquid. In the present invention, because air is sucked into the inner side of the recovery tube during the recovery process, the present invention determines whether it is a gas phase or a liquid phase at the bottom of the recovery tube through the speed difference caused by the density difference between gas and liquid. In the liquid phase, the second piston in the recovery tube moves downward and the second piston in the pump-out tube moves upward, so that the coupling liquid enters a new use cycle again. In the gas phase, the controller controls the electric exhaust valve to open to discharge excess gas from the recovery tube, thereby realizing the coupling agent supply during the entire detection process.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0045] Example 1, please refer to Figure 1-Figure 5 and Figure 8 , the present invention provides a technical solution:

[0046] A medical imaging diagnostic ultrasound probe device, comprising a kit 3 and a controller 8, wherein the kit 3 can be sleeved on the outside of the probe part 2, and an acceleration sensor 24 capable of obtaining the moving direction of the probe is arranged in the kit 3, and two acceleration sensors 24 are respectively used to sense the displacement in the front and rear directions, and an extrusion tube 26 is fixedly connected to the inside of the kit 3, and the front and rear ends of the extrusion tube 26 are respectively connected to a front tube 261 and a rear tube 262, and the front tube 261 and the rear tube 262 are respectively arranged on the inside of the front and rear ends of the kit 3, and the bottom ends of the front tube 261 and the rear tube 262 are connected to a discharge tube 22, and after the acceleration sensor 24 obtains the displacement of the probe, the coupling agent is applied to the forward end through the discharge tube 22;

When the plug 264 is in the middle position of the extrusion tube 26, the second one-way valve 19 is in a blocked state. When the plug 264 is at the front end of the extrusion tube 26 under the action of the electric push rod 263, the second one-way valve 19 is connected to the rear tube 262. At this time, the discharge pipe 22 at the rear end can discharge the coupling agent. When the plug 264 is at the rear end of the extrusion tube 26 under the action of the electric push rod 263, the second one-way valve 19 is connected to the front tube 261. At this time, the discharge pipe 22 at the front end can discharge the coupling agent.

[0049] Under the above settings, the present invention is operated by operating the operating part 1 of the probe, and the kit 3 of the present invention is put on the outside of the probe part 2. The connection mode of the kit 3 and the probe part 2 can be a detachable mode such as a snap connection. Because the probe will slide over a large amount of skin when moving forward and backward, at this time, it is necessary to replenish the coupling agent in time to achieve the detection effect.

The two sliders 14 can be flush with the left and right sides of the probe part 2. Grooves 20 are provided at the front and rear ends of the sliders 14, and a suction hole 21 is provided on the inner side of the groove 20. After the probe slides over the skin in the front and rear direction, excess coupling agent will be squeezed into the groove 20.

When the second piston 16 in the recovery tube 13 moves upward, the excess coupling agent can be sucked into the recovery tube 13.

[0054] Under the above setting, after the probe slides over the skin in the front-back direction, the excess coupling agent will squeeze into the groove 20. In order to realize the recovery of the residual coupling agent in the surrounding area, reduce the overall usage of the coupling agent, reduce the discomfort caused by the coupling agent to the detected person, and reduce the subsequent wiping situation, the second piston 16 in the recovery tube 13 of the present invention moves upward, and the groove 20 is used to temporarily store the coupling agent. The excess coupling agent will be concentrated in the groove 20 and enter the recovery tube 13 through the extraction hole 21, the U-shaped tube 231, and the reflux tube 23 to realize recovery;

[0055] Specifically, springs 17 for achieving a reset effect are provided on the inner sides of the pump-out tube 12 and the recovery tube 13. In the initial state, the second piston 16 in the pump-out tube 12 is at the bottom end of the pump-out tube 12, and the second piston 16 in the recovery tube 13 is at the middle position of the recovery tube 13.

[0056] Specifically, the bottom ends of the pump outlet pipe 12 and the recovery pipe 13 are connected through the first one-way valve 18, and the coupling liquid recovered in the recovery pipe 13 can enter the inner side of the bottom end of the pump outlet pipe 12. The input resistance of the first one-way valve 18 is greater than the electric exhaust valve 27. When exhausting, the gas is discharged preferentially through the electric exhaust valve 27.

[0057] Specifically, the bottom end of the recovery pipe 13 is also connected to an electric exhaust valve 27, and a gas-liquid analysis component is also provided at the bottom end of the electric exhaust valve 27 for analyzing whether the coupling liquid or gas is present.

The device also includes a bottle body 4, and the bottom end and the middle position of the bottle body 4 are respectively connected to the first suction tube 5 and the second suction tube 6. The first suction tube 5 and the second suction tube 6 are connected to the same internal joint 10, and the internal joint 10 can be snapped into the external joint 11. After snapping, the first suction tube 5 is only connected to the inner side of the top end of the recovery tube 13, and the second suction tube 6 is only connected to the inner side of the top end of the pump-out tube 12.

When the first piston 15 moves downward, the second piston 16 in the pump-out pipe 12 moves upward and realizes the front placement of the coupling agent through the one-way pipe 25. When the first piston 15 moves upward, the second piston 16 in the pump-out pipe 12 moves downward and discharges the coupling agent through the second one-way valve 19 and the front pipe 261.

[0060] In the present invention, the coupling agent collected by the recovery tube 13 is only used in the current exploration, and a new set 3 needs to be replaced when it is used next time;

[0061] When the second piston 16 in the recovery pipe 13 moves downward and the second piston 16 in the pump-out pipe 12 moves upward, that is, when the first piston 15 moves downward, the coupling liquid recovered in the recovery pipe 13 can enter the pump-out pipe 12 through the first one-way valve 18, so that the coupling liquid enters a new use cycle again, thereby reducing the overall use amount of the coupling liquid;

[0062] In the present invention, since air is sucked into the inner side of the recovery pipe 13 during the recovery process, the present invention determines whether it is a gas phase or a liquid phase at the bottom of the recovery pipe 13 by the speed difference caused by the density difference between gas and liquid. When it is a liquid phase, the second piston 16 in the recovery pipe 13 moves downward, and the second piston 16 in the pump-out pipe 12 moves upward, so that the coupling liquid enters a new use cycle again. When it is a gas phase, the controller 8 controls the electric exhaust valve 27 to open, and the excess gas is discharged from the recovery pipe 13, thereby realizing the coupling agent supply in the entire detection process;
