Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of medical supplies, and particularly relates to a coupling agent extrusion bottle. BACKGROUND

[0002] The coupling agent is a medium used in the equipment or system for ultrasonic imaging. Its main function is to help the ultrasonic wave to pass through the object and form an image, and to remove the air between the probe and the measured object to ensure that the ultrasonic wave can effectively penetrate the object and achieve the detection purpose. At present, the coupling agent used in medical ultrasonic examination is usually packed in a simple soft rubber bottle, and the coupling agent itself is a weakly flowing viscous paste. The existing coupling agent has the following problems: 1. When used, the bottle body needs to be inverted and shaken to make the remaining coupling agent gather at the bottle opening so as to be squeezed out. If the force is too strong, the coupling agent can be spilled to other places. 2. When the coupling agent is used to the end, the remaining coupling agent in the bottle cannot be used to the maximum, causing unnecessary waste of resources.

[0003] The patent document with the publication number CN217779576U discloses a coupling agent bottle convenient to squeeze, a piston is arranged in the bottle cavity of the bottle body, when the coupling agent in the bottle cavity is used to a small amount and is inconvenient to squeeze out, the pipe cover at the bottom is opened, the push rod is inserted into the connecting pipe for connection, the piston is pushed by the push rod to take out a small amount of coupling agent on the inner wall of the bottle cavity, and waste is avoided. However, the push rod and the bottle body of the above-mentioned bottle are designed in a split body, and the bottle body must rely on the push rod for extrusion, which is not convenient to use. In addition, if the push rod is lost, the extrusion function cannot be realized. UTILITY MODEL CONTENTS

[0004] The utility model aims at designing a coupling agent extrusion bottle, which realizes extrusion of the coupling agent by rotating the rotary bottle bottom and using the screw rod to drive the extrusion plate. Since the extrusion plate is sealingly connected with the inner wall of the bottle body, and the elastic sealing sleeve is arranged between the screw rod and the extrusion plate, the coupling agent in the bottle body can be completely discharged, and the coupling agent can be added from the upper end of the bottle body to realize repeated use.

[0005] The technical problem to be solved by the utility model is solved by the following technical scheme: a coupling agent extrusion bottle, comprising a bottle body, an extrusion opening, a rotary bottle bottom, a screw rod, an extrusion plate and an elastic sealing sleeve.

[0006] The extrusion opening is detachably arranged at the top of the bottle body, the rotary bottle bottom is rotatably arranged at the bottom of the bottle body, and the rotary bottle bottom is sealingly connected with the bottle body.

[0007] The extrusion plate is slidingly arranged in the bottle body and sealingly connected with the inner wall of the bottle body, and the screw rod is vertically arranged on the rotary bottle bottom and threadedly connected with the extrusion plate.

[0008] An elastic sealing sleeve is arranged between the screw rod and the extrusion plate.

[0009] The upper end surface of the screw rod is flush with the upper end surface of the bottle body, and the connecting portion at the lower end of the extrusion opening is threadedly connected with the outer wall of the bottle body, so that the bottle body is prevented from being left with residual coupling agent.

[0010] The utility model discloses a sealing ring is further included, the sealing ring sets up on the lateral wall of extrusion plate. Utilize the gap between extrusion plate and bottle body lateral wall to seal with sealing ring, avoid the coupling agent from the gap between extrusion plate and bottle body lateral wall and enter the space below extrusion plate.

[0011] The utility model discloses a limiting protrusion is arranged on the outer wall of the lower end of the bottle body, the limiting protrusion is distributed along the circumference of the bottle body, and the rotating bottle bottom is provided with an annular limiting groove matched with the limiting protrusion. The annular limiting groove on the rotating bottle bottom is limited by the limiting protrusion on the outer wall of the lower end of the bottle body, so that the relative rotation between the rotating bottle bottom and the bottle body is realized.

[0012] The utility model discloses a assembling opening matched with the limiting protrusion is arranged on the top of the limiting groove. By setting the assembling opening matched with the limiting protrusion on the top of the limiting groove, the quick assembly and disassembly of the rotating bottle bottom are facilitated.

[0013] The utility model discloses that more than three limiting protrusions are evenly distributed along the circumference of the bottle body. By setting more than three limiting protrusions, the difficulty of aligning the limiting protrusion with the assembling opening is increased, and the rotating bottle bottom and the bottle body are prevented from being separated during use.

[0014] The utility model discloses a sealing ring with an L-shaped longitudinal section, which is installed at the bottom of the bottle body and located between the bottle body and the rotating bottle bottom. The sealing ring with an L-shaped longitudinal section can be directly buckled at the bottom of the bottle body, facilitating the limiting installation.

[0015] The utility model discloses that the cross section of the inner cavity of the bottle body is non-cylindrical or the side wall of the extrusion plate is provided with an anti-rotation platform. The cross section of the inner cavity of the bottle body is set as non-cylindrical or the anti-rotation platform is arranged on the side wall of the extrusion plate, so that the rotation of the extrusion plate during the up-down sliding along the axial direction of the bottle body is avoided.

[0016] The utility model discloses that the extrusion opening is a conical extrusion head. The extrusion opening is set as conical, which is used for limiting the extrusion amount of the coupling agent.

[0017] The utility model discloses that the extrusion opening is a ball smearing structure. The extrusion opening is designed as a ball smearing structure, which is uniform in smearing and can avoid the spilling of the coupling agent caused by excessive extrusion force.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: The coupling agent squeeze bottle of this utility model has a detachable squeeze port located at the top of the bottle body, and a rotatable rotating bottle bottom located at the bottom of the bottle body, with the rotating bottle bottom sealed to the bottle body, ensuring the sealing performance of the squeeze bottle. Since the squeeze plate is slidably mounted inside the bottle body and sealed to the inner wall of the bottle body, and the screw is vertically mounted on the rotating bottle bottom and threadedly connected to the squeeze plate, with an elastic sealing sleeve between the screw and the squeeze plate, the coupling agent can be squeezed out from the squeeze port by rotating the rotating bottle bottom.

[0019] Because the extrusion plate is sealed to the inner wall of the bottle, and an elastic sealing sleeve is provided between the screw and the extrusion plate, the coupling agent inside the bottle is completely extruded without leaving any residue, and the coupling agent is prevented from leaking into the space below the extrusion plate.
