[0004] The inventors have discovered in their daily work that in the process of administering medication to the intestine with the aid of a syringe, there is a problem in that the existing syringe, for example, uses an electric mechanism to perform the pushing operation. In the actual operation, since medical staff hold the tool with one hand and the medication time is relatively long, when the electric mechanism is used, the weight of the tool itself will increase, and the burden on the medical staff's arms will increase, making the medical staff's arms prone to fatigue and shaking, which may seriously cause damage to the patient. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art that the use of an electric mechanism will increase the weight of the tool itself and increase the burden on the arms of medical staff, making the arms of medical staff prone to fatigue and shaking, which may seriously cause damage to patients, and to propose an ointment injector.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an ointment infuser, comprising a medicine barrel, a discharge pipe and an extrusion assembly, the discharge pipe is fixedly connected to the discharge end of the medicine barrel, the inner wall of the discharge pipe is provided with an extrusion plate, the surface of the medicine barrel is provided with an auxiliary assembly, the auxiliary assembly comprises a U-shaped frame, the extrusion assembly is arranged on the inner wall of the U-shaped frame, the extrusion assembly comprises a rotating shaft, the rotating shaft is rotatably connected to the inner wall of the U-shaped frame, the inner wall of the U-shaped frame is installed with a torsion spring, the side surface of the rotating shaft is fixedly connected with a paddle plate, the surface of the paddle plate is provided with a storage cavity, the paddle plate is located on the inner wall of the storage cavity and is slidably connected with a push plate, the lower surface of the push plate is fixedly connected with a limiting spring, and the side surface of the extrusion plate is fixedly connected with a pressing frame.

Through the cooperation between the limiting pin and the sliding groove, the maximum movement distance of the push plate can be limited.

[0008] Preferably, there are two rotating shafts, which are symmetrically arranged with respect to the shift plate. The limit spring is fixedly connected to the inner wall of the storage cavity. A tooth groove is provided on the surface of the pressing frame. The push plate is plugged into the inner wall of the tooth groove. A limit spring is provided, and the position of the push plate can be constrained by the limit spring, so that the push plate can slide inside the shift plate.

[0009] Preferably, there are two limiting pins, which are symmetrically arranged with respect to the push plate. The limiting pins are slidably connected to the inner wall of the sliding hole. A push plate is provided, and when the push plate is pulled by the paddle plate, the push plate can be inserted into the tooth groove and push the pressing frame to move, thereby achieving the extrusion effect of the pressing frame.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] In the utility model, by arranging an auxiliary component and an extrusion component, when administering medicine, the medicine is injected into the medicine barrel. After the filling of the medicine is completed, the extrusion plate is installed into the medicine barrel, and the handle is then held to insert the discharge tube into the affected part of the patient by operating the handle. When the above operation is completed to administer medicine, the dial plate is moved with the index finger and the middle finger. The dial plate is subjected to force and pushes the push plate under the constraint of the rotating shaft. The rotating shaft drives the torsion spring to deform under the action of the dial plate. At the same time, the push plate is subjected to force to rotate, and pushes the pressing frame during the rotation. The pressing frame pushes the extrusion plate under the action of the push plate. The extrusion plate is pushed to squeeze the ointment in the medicine barrel, and the ointment is squeezed through the discharge tube and injected into the affected part of the patient. When the dial plate is rotated to the maximum angle, the dial plate is released, the dial plate loses the force applied to the rotating shaft, the rotating shaft loses the force applied to the torsion spring, and the torsion spring rebounds while losing the force and drives the rotating shaft to rotate. When the lever is in contact with the pressing frame, the limit spring is squeezed and deformed, and the push plate gradually slides into the storage cavity and disengages from the tooth groove when squeezing the limit spring. When the lever reaches the surface of the trapezoidal block, the push plate loses the constraint of the pressing frame, and the limit spring loses the pressure applied by the push plate and rebounds, and pushes the push plate into another card slot during the rebound process. Then, the above steps are repeated to inject the subsequent ointment into the affected part of the patient. By setting the auxiliary components and the squeezing components, the weight of the device itself is reduced, thereby reducing the problem of increased weight of the device caused by the use of an electric mechanism to drive the device, which increases the burden on medical staff, and further improves the stability of the device when in use.

[0022] The specific configuration and function of the auxiliary component 4 and the extrusion component 5 will be described in detail below.

[0023] In this embodiment: the extrusion assembly 5 includes a rotating shaft 51, which is rotatably connected to the inner wall of the U-shaped frame 42, and a torsion spring 52 is installed on the inner wall of the U-shaped frame 42. A shift plate 53 is fixedly connected to the side surface of the rotating shaft 51, and a storage cavity is opened on the surface of the shift plate 53. The shift plate 53 is located on the inner wall of the storage cavity and is slidably connected to a push plate 54. The lower surface of the push plate 54 is fixedly connected to a limiting spring 55, and the side surface of the extrusion plate 3 is fixedly connected to a pressing frame 56.

[0024] Specifically, a limiting pin 57 is fixedly connected to the side surface of the push plate 54, and a sliding groove is opened on the side surface of the dial plate 53. The limiting pin 57 is set, and the maximum movement distance of the push plate 54 can be limited by the cooperation between the limiting pin 57 and the sliding groove.

[0025] Specifically, there are two rotating shafts 51, which are symmetrically arranged about the dial plate 53, the limit spring 55 is fixedly connected to the inner wall of the storage cavity, the surface of the pressing frame 56 is provided with a tooth groove, and the push plate 54 is plugged into the inner wall of the tooth groove.

[0026] In this embodiment, a limit spring 55 is provided, and the position of the push plate 54 can be constrained by the limit spring 55 , so that the push plate 54 can slide inside the dial plate 53 .

[0027] Specifically, there are two limiting pins 57, which are symmetrically arranged with respect to the push plate 54. The limiting pins 57 are slidably connected to the inner wall of the sliding hole 58. The push plate 54 is provided. When the push plate 54 is pulled by the shift plate 53, the push plate 54 can be inserted into the tooth groove and push the pressing frame 56 to move, thereby achieving the extrusion effect of the pressing frame 56.

[0028] In this embodiment: the auxiliary component 4 also includes a mounting ring 41, the mounting ring 41 is fixedly connected to the arc surface of the medicine barrel 1, the U-shaped frame 42 is fixedly connected to the arc surface of the mounting ring 41, the side surface of the U-shaped frame 42 is fixedly connected to a trapezoidal block 43, the side surface of the U-shaped frame 42 is fixedly connected to a connecting plate 44, and the lower surface of the connecting plate 44 is fixedly connected to a handle 45.

[0029] In this embodiment, a mounting ring 41 is provided, through which the position of the U-shaped frame 42 can be fixed, thereby achieving a supporting effect of the U-shaped frame 42 .

[0030] Specifically, there are two U-shaped frames 42 , which are symmetrically arranged about the mounting ring 41 . The U-shaped frames 42 can be used to constrain the position of the rotating shaft 51 , thereby ensuring the stability of the rotating shaft 51 .

[0031] Working principle: When administering the medicine, inject the medicine into the medicine barrel 1. After the medicine is filled, install the squeezing plate 3 into the medicine barrel 1, then hold the handle 45, and insert the discharge tube 2 into the patient's affected part by operating the handle 45. When the above operations are completed and the medicine is administered, use the index finger and middle finger to move the dial plate 53. The dial plate 53 is subjected to force and pushes the push plate 54 under the constraint of the rotating shaft 51. The rotating shaft 51 drives the torsion spring 52 to deform under the action of the dial plate 53, and the push plate 54 is forced to rotate. The pressing frame 56 is pushed during the rotation, and the pressing frame 56 pushes the squeezing plate 3 under the action of the pushing plate 54, and the squeezing plate 3 is pushed to squeeze the ointment in the medicine barrel 1, and the ointment is squeezed through the discharge pipe 2 and injected into the affected part of the patient. When the paddle plate 53 rotates to the maximum angle, the paddle plate 53 is released, the paddle plate 53 loses the force applied to the rotating shaft 51, and the rotating shaft 51 loses the force applied to the torsion spring 52. The torsion spring 52 rebounds when losing its force and drives the rotating shaft 51 to rotate, and the rotating shaft 51 is rotated. When the lever 53 is in contact with the pressing frame 56, the limit spring 55 is squeezed and deformed. When squeezing the limit spring 55, the push plate 54 gradually slides into the storage cavity and disengages from the tooth groove. When the lever 53 reaches the surface of the trapezoidal block 43, the push plate 54 loses the constraint of the pressing frame 56. At the same time, the limit spring 55 loses the pressure applied by the push plate 54 and rebounds. During the rebound, the push plate 54 is pushed into another slot. Then, the above steps are repeated to inject the subsequent ointment into the affected part of the patient. By setting the auxiliary component 4 and the squeezing component 5, the weight of the device itself is reduced, thereby reducing the problem of increased weight of the device caused by the use of an electric mechanism to increase the burden on medical staff, and further improving the stability of the device when in use.
