Abstract
Description
Technical Field
[0001] The technical solution relates to a medical auxiliary device, in particular to a color ultrasound coupling agent application auxiliary sleeve. Background Art
[0002] As we all know, human color Doppler ultrasound is an examination that uses ultrasound to form graphics on the screen, and can examine multiple parts of the human body. During the color Doppler ultrasound examination, it is often necessary to apply a large amount of coupling agent to the chest and abdomen and other parts. The purpose is to reduce the acoustic impedance difference between the probe and the skin, thereby reducing the reflection loss of ultrasonic energy at this interface, making the image clearer and improving the accuracy of the ultrasound examination. However, medical staff often apply excessive amounts of coupling agent to patients, which not only causes discomfort to patients, but also makes it more difficult for patients to clean up later, and also causes waste.
[0003] Chinese patent 202320489532.0 discloses a color Doppler coupling agent smearing device, which has a coupling agent smearing part on one side of the ultrasound probe and a cleaning part with an adsorption pad on the other side. When the coupling agent flowing out of the smearing part is used by the probe, it is adsorbed by the cleaning part, thus achieving the effect of cleaning the skin. However, this technical solution has the following problems: (1) The device needs to move in a straight line, so that the coupling agent in the front can be easily adsorbed by the adsorption pad at the back. However, in practice, doctors often move the color Doppler probe in an arc shape, and sometimes in a circle shape, so the coupling agent will overflow from the left and right sides of the device, and the effect of cleaning the excess coupling agent will not be achieved; (2) Even if it moves in a straight line, the lower end of the ultrasound probe will divert part of the coupling agent to both sides, resulting in the inability of the cleaning part at the back to adsorb, thereby reducing the cleaning effect. Utility Model Content
[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a color Doppler coupling agent application auxiliary sleeve, which can achieve the technical effects of reducing coupling agent waste, reducing human discomfort, and facilitating subsequent cleaning of the human body under the premise of ensuring normal color Doppler detection. The specific scheme is as follows.
[0005] The color ultrasound coupling agent smearing auxiliary sleeve is characterized in that it includes a cylindrical sleeve body, which is hollow and has a cavity for storing coupling agent inside. A liquid inlet hole is opened on the top of the sleeve body and is connected to the control switch. A cavity is provided in the center of the sleeve body and passes through from top to bottom. The middle of the cavity is an inner cavity with an enlarged diameter and a cylindrical shape. A main spring is provided on the inner wall of the inner cavity. Below the cavity is an smearing cavity with an enlarged diameter and a cylindrical shape. The bottom of the sleeve body is a circular annular portion with a liquid outlet hole opened on the inner side of the annular portion. The probe locking sleeve is installed in the cavity.
[0006] The probe locking sleeve comprises a pipe sleeve, an adjusting cap is arranged above the pipe sleeve, a locking cap is arranged below the pipe sleeve, the inner wall of the adjusting cap is threadedly connected to the outer wall of the pipe sleeve, and the inner wall of the locking cap is threadedly connected to the outer wall of the pipe sleeve.
[0007] A clamping gap is arranged below the pipe sleeve.
[0008] The outer side of the probe locking sleeve and the inner wall of the sleeve cavity are provided with mutually matching guide structures, wherein the guide structure refers to longitudinal guide grooves spaced apart on the inner cavity and guide strips matching therewith are spaced apart on the side wall of the locking cap. The bottom of the locking cap is an anti-slip cover edge.
[0009] The cavities are distributed in the casing along the circumferential direction and have gaps, and the casing is made of transparent material, so that the gaps form viewing windows that do not contain liquid. Preferably, the cavities occupy 270° (or three quarters) of the casing along the circumferential direction.
[0010] The control switch includes a seat body fixed on the top of the sleeve body, a channel is provided in the seat body, the top of the channel is a connecting port, the bottom of the channel is connected to the liquid inlet hole on the top of the sleeve body, a control shaft is arranged in the seat body, the control shaft intersects and is perpendicular to the channel, a through hole is opened in the middle of the control shaft, a button is fixed at the end of the control shaft, and a compression spring is also provided on the control shaft and is located between the button and the seat body.
[0011] The outer side of the bottom of the sleeve body is provided with an annular groove, and the annular groove is surrounded by absorbent cotton.
[0012] Further explanation of the effect of this technical solution:
[0013] In this solution, a cylindrical application cavity is wrapped in the sleeve, and an annular portion is set at the bottom of the sleeve, and the outer surface of the annular portion is circular: first, it plays a rolling role, flattens the coupling agent well, and makes the coupling agent evenly cover the skin surface, improving the detection accuracy and detection efficiency of the color Doppler ultrasound probe; second, it can bind the excess coupling agent in the application cavity, reducing unnecessary waste and facilitating subsequent cleaning by the patient. When the coupling agent in the application cavity is about to run out, the medical staff can continue to inject it by pressing a button;
[0014] In this solution, an external high-pressure coupling agent container needs to be connected through the connection port to assist in the injection of coupling agent. At the same time, the depth of pressing the button determines the overlap between the through hole and the channel, that is, the flow rate of the coupling agent. Therefore, medical staff can control the amount of coupling agent outflow by controlling the depth of pressing the button;
[0015] This solution has an annular groove on the outside of the bottom of the sleeve, and the annular groove is surrounded by absorbent cotton. Because the annular part has bound most of the coupling agent in the application cavity, only a small part is spread on the skin and overflows, so the absorbent cotton can further clean the skin by wiping and adsorbing, improving the patient's comfort. The absorbent cotton can be simply fixed in the annular groove by double-sided adhesive bonding;
[0016] This solution has the effect of adjusting the extension length of the color Doppler ultrasound probe. Due to the differences in fatness and age of the human body, the abdomen of different human bodies will show different convexities and concavities after lying down. For patients with convex abdomen (fat), the color Doppler ultrasound probe needs to be shortened appropriately, and vice versa, the color Doppler ultrasound probe needs to be extended so that the coupling agent can be bound in the application cavity while the color Doppler ultrasound probe works normally. Therefore, this technical solution is provided with a main spring and an adjustment cap. When the adjustment cap is further rotated, the distance between the adjustment cap and the locking cap is shortened, the locking cap compresses the main spring, the entire sleeve moves up, and the color Doppler ultrasound probe also moves up and shortens. Similarly, when the adjustment cap is rotated in the opposite direction, the color Doppler ultrasound probe extends downward and beyond the application cavity under the elastic force of the main spring to adapt to patients with concave abdomen (thin). The main spring not only plays a key role in adjusting the extension length of the color Doppler ultrasound probe, but also can adaptively adjust when the color Doppler ultrasound probe is under pressure.
[0017] 5. The guide device can stabilize the direction of the color Doppler ultrasound probe to prevent it from rotating during operation. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0024] Example 1, see attached Figure 1-5 The color Doppler coupling agent smearing auxiliary sleeve is characterized in that it includes a cylindrical sleeve body 1, which is hollow and has a cavity 1-1 for storing coupling agent inside.

[0025] The probe locking sleeve comprises a sleeve 3, an adjusting cap 2 is arranged above the sleeve, a locking cap 7 is arranged below the sleeve, the inner wall of the adjusting cap is connected with the outer wall of the sleeve through a thread 3-1, and the inner wall of the locking cap is connected with the outer wall of the sleeve through a thread. A detachable thickened anti-slip sleeve is arranged inside the sleeve.
[0026] A clamping gap 3-2 is provided below the pipe sleeve.
[0027] The outer side of the probe locking sleeve and the inner wall of the sleeve cavity are provided with mutually matching guide structures, wherein the inner cavity is provided with longitudinal guide grooves 1-2, and the side wall of the locking cap is provided with matching guide strips 7-1. The bottom of the locking cap is a non-slip cover edge 7-2.
[0028] The cavities are distributed in the sleeve along the circumferential direction and have gaps. The sleeve is made of transparent material, so that the gaps form viewing windows 1-7. Preferably, the cavities occupy 270° (or three quarters) of the sleeve along the circumferential direction. The viewing windows facilitate medical staff to observe the exact position of the color Doppler ultrasound probe.
[0029] The control switch includes a seat body 5-1, a channel 5-2 is provided in the seat body, the top of the channel is a connecting port, the bottom of the channel is connected to the liquid inlet hole at the top of the sleeve body, a control shaft 5-3 is arranged in the seat body, the control shaft intersects and is perpendicular to the channel, a through hole 5-4 is opened in the middle of the control shaft, a button 5-6 is fixed to the end of the control shaft, and a compression spring 5-5 is also provided on the control shaft and is located between the button and the seat body.
[0030] An annular groove is formed on the outer side of the bottom of the sleeve body, and a suction cotton 6 is surrounded in the annular groove.
[0031] This technical solution is used as follows:
[0032] First, install the color Doppler ultrasound probe into the tube sleeve and screw the locking cap. The locking cap compresses the lower end of the tube sleeve during the upward screwing process to tighten the color Doppler ultrasound probe in a way of shrinking the gap.
[0033] Then, the tube sleeve with the color Doppler ultrasound probe installed is passed through the cavity from the smear cavity, and the adjusting cap is screwed into the top, so that the color Doppler ultrasound probe is fixed in the cavity;
[0034] Just connect the high-pressure coupling agent container to the connection port of the control switch through a pipe.
[0035] When using, the medical staff holds the sleeve and places the index finger on the button (such as the attached Figure 5 As shown in the figure). When the index finger presses the button, the through hole overlaps with the channel, and the high-voltage coupling agent enters the chamber through the channel, and then enters the application chamber through the outlet hole at the bottom. During the movement of the medical staff, the coupling agent is applied to the patient's abdomen to complete the color Doppler ultrasound test.
[0036] Further explanation of the effect of this technical solution:
[0037] In this solution, a cylindrical application cavity is wrapped in the sleeve, and an annular portion is set at the bottom of the sleeve, and the outer surface of the annular portion is circular: first, it plays a rolling role, flattens the coupling agent well, and makes the coupling agent evenly cover the skin surface, improving the detection accuracy and detection efficiency of the color Doppler ultrasound probe; second, it can bind the excess coupling agent in the application cavity, reducing unnecessary waste and facilitating subsequent cleaning by the patient. When the coupling agent in the application cavity is about to run out, the medical staff can continue to inject it by pressing a button;
[0038] In this solution, the depth of pressing the button determines the overlap between the through hole and the channel, that is, the flow rate of the coupling agent. Therefore, medical staff can control the amount of coupling agent outflow by controlling the button.
[0039] This solution has an annular groove on the outside of the bottom of the sleeve, and the annular groove is surrounded by absorbent cotton. Because the annular part has bound most of the coupling agent in the application cavity, only a small part is spread on the skin and overflows, so the absorbent cotton can further clean the skin by wiping and adsorbing, improving the patient's comfort. The absorbent cotton can be simply fixed in the annular groove by double-sided adhesive bonding;
[0040] This solution has the effect of adjusting the extension length of the color Doppler ultrasound probe. Due to the differences in fatness and age of the human body, the abdomen of different human bodies will show different convexities and concavities after lying down. For patients with convex abdomen (fat), the color Doppler ultrasound probe needs to be shortened appropriately, and vice versa, the color Doppler ultrasound probe needs to be extended so that the coupling agent can be bound in the application cavity while the color Doppler ultrasound probe works normally. Therefore, this technical solution is provided with a main spring and an adjustment cap. When the adjustment cap is further rotated, the distance between the adjustment cap and the locking cap is shortened, the locking cap compresses the main spring, the entire sleeve moves up, and the color Doppler ultrasound probe also moves up and shortens. Similarly, when the adjustment cap is rotated in the opposite direction, the color Doppler ultrasound probe extends downward and beyond the application cavity under the elastic force of the main spring to adapt to patients with concave abdomen (thin). The main spring not only plays a key role in adjusting the extension length of the color Doppler ultrasound probe, but also can adaptively adjust when the color Doppler ultrasound probe is under pressure.
[0041] The guide device can stabilize the direction of the color Doppler ultrasound probe to prevent it from rotating during operation.
