Description

Technical Field

[0001] The invention belongs to the field of medical devices, and in particular relates to a symmetrical ointment extruder. Background Art

[0002] There are non-surgical methods for hemorrhoids, such as medication, injection, and physical therapy. Regular drugs such as Chinese medicine hemorrhoid cream can reduce edema, relieve symptoms, and relieve pain. The hemorrhoid cream currently available on the market is a small tube of 4g. Generally speaking, one tube can be used 3 to 4 times. Patients generally use it for 7 consecutive days. If there is no effect, further examination or other drugs are used. However, after the drug is squeezed out of the paste tube, it is difficult to squeeze out all the ointment remaining in the paste tube. The less the remaining ointment, the more difficult it is to control the amount of extrusion. Due to the special part of the ointment application, patients are only willing to do it themselves. When there is less ointment in the paste tube and it is difficult to squeeze out, it is difficult for patients to verify that they have squeezed out enough. In this way, insufficient dosage affects the efficacy; on the other hand, due to the difficulty in operation, patients often abandon the paste tube with a certain amount of ointment remaining, causing a lot of waste and polluting the environment; the third aspect leads to that a tube of ointment can only be used 2 to 3 times, and 3 to 4 tubes are needed for 7 consecutive days, and the last tube of ointment has more remaining ointment. Therefore, in the care of hemorrhoids, there is a need for an ointment squeezer that is simple and easy for patients to operate by themselves without visual conditions, so that patients can squeeze out as much ointment as possible from the ointment tube without any residue. At the same time, the amount squeezed out each time is accurate, so as to maximize the number of times the ointment can be used. Summary of the invention

[0003] In view of the shortcomings of the prior art, the present invention aims to provide a symmetrical ointment squeezer with a simple structure, which is easy for patients to squeeze out the ointment themselves without visual inspection, and is convenient for patients to squeeze out as much ointment in the ointment tube as possible without residue. At the same time, the amount squeezed out each time is accurate, so the ointment can be used a maximum number of times.

[0004] In order to achieve the above object, the present invention adopts the following technical scheme:

[0005] A symmetrical ointment extruder comprises a clamp and a slider, wherein the clamp is composed of two shells, the inner side surfaces of the two shells are semicircular groove surfaces, one end of the two shells is hinged to each other, and the two shells are respectively provided with semicircular holes corresponding to each other on the same end surface; the two shells are provided with racks arranged along the length direction on opposite sides, the first side tooth surface of the rack away from the semicircular hole is inclined relative to the reference surface of the rack, and the second side tooth surface of the rack close to the semicircular hole is perpendicular to the reference surface of the rack, so that the tooth tips are inclined toward the semicircular hole;

[0006] Guide bars parallel to each other are arranged inside each housing and on the left and right sides of the rack, and the guide bars are parallel to the closing surfaces of the pair of housings, and the adjacent guide bars corresponding to each other in the two housings are spaced apart from each other to form a moving channel for the slider;

[0007] The slider includes two symmetrical pressing blocks. When the two shells are closed, the two pressing blocks are close to each other and can be accommodated in the moving channel. Corresponding protrusions and depressions are arranged between the opposite sides of the two pressing blocks. The two pressing blocks can slide in a direction parallel to the guide strip and also move in a direction perpendicular to the guide strip.

[0008] A spring sheet facing the rack is provided on one side of the two pressing blocks facing away from each other, the first end of the spring sheet is close to the semicircular hole and connected to the pressing block, the second end of the spring sheet extends toward the rack and is embedded between the tooth tips, the spring sheet is inclined relative to the surface of the pressing block, when the side of the two pressing blocks facing away from each other approaches the guide bar, the angle between the spring sheet and the surface of the pressing block decreases, and when the side of the two pressing blocks facing away from each other is separated from the guide bar, the angle between the spring sheet and the surface of the pressing block increases.

[0009] A center seam is arranged in the center of the outer sides of the two shells, and two ends of the center seam extend to the upper and lower ends of the shells, and the center seam runs through the inner and outer surfaces of the shells. A row of racks parallel to the center seam are arranged on the left and right sides of the center seam on the inner side of the shells.

[0010] The left and right sides of the pressing block are also provided with L-shaped folded edges facing the guide strip, and a U-shaped groove with a width greater than the thickness of the guide strip is formed between the opposite sides of the two pressing blocks and the L-shaped folded edges of the pressing blocks. The two guide strips of each shell are respectively embedded in the left and right U-shaped grooves of a pressing block, so as to keep the pressing block from flipping with the shell and moving along the guide strip inside the shell.

[0011] When the shells are close together, a columnar space for accommodating the paste tube is formed between the two semicircular groove surfaces; when the semicircular holes are closed together, a through hole is formed for the extruder head at the upper end of the paste tube to pass through.

[0012] The slider also includes a frame surrounding the two pressure blocks, and a channel arranged along the length direction of the shell penetrates from one end of the frame close to the semicircular hole of the shell to the other end of the frame away from the semicircular hole of the shell. When a pair of shells are closed, the frame can be accommodated in the moving channel, and the frame is used to keep the two pressure blocks moving synchronously along the guide bar.

[0013] The thickness of the gap formed by the pressed blocks being brought close to each other is not less than the thickness of the paste tube when it is completely flattened.

[0014] A symmetrical ointment squeezer provided by the present invention realizes quantitative sliding of the pressing block and quantitative extrusion of the ointment by loosening and closing the shell body, utilizing the meshing of the spring sheet of the slider with the rack and the change in the inclination angle of the spring sheet relative to the surface of the pressing block. The present invention has a simple structure and is easy for the patient to squeeze out the ointment by himself without visual inspection, so that the patient can squeeze out as much ointment in the ointment tube as possible without residue. At the same time, the extrusion amount each time is accurate, so the ointment can be used a maximum number of times. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In order to make the purpose, technical solution and advantages of the present invention more clearly explained, the present invention will be further explained in detail below in conjunction with the accompanying drawings.

[0023] The reference plane of the rack described in the present invention is an imaginary plane of the basic rack, and the plane is parallel to the tooth top plane.

[0024] like Figure 1 As shown, the symmetrical paste extruder comprises: a clamp and a slider 2. The clamp is composed of two shells 3. One end of a pair of shells 3 is hinged to each other. One end surface of the pair of shells 3 is respectively provided with a corresponding semicircular hole 4. When the pair of shells 3 are closed together, a columnar space for accommodating the paste tube 5 is formed between the opposite sides thereof, and the two semicircular holes 4 are closed to each other to form a through hole for Figure 2 The extruder head 6 at the upper end of the paste tube 5 shown passes through it, and a pair of outer sides of the shell 3 are centrally arranged with a middle seam 7 extending to the upper and lower ends. The middle seam 7 runs through the inner and outer surfaces of the shell 3. The inner side of the shell 3 is located on the left and right sides of the middle seam, and a row of racks 8 parallel to the middle seam 7 are respectively arranged. Figure 6 As shown, the first side tooth surface 81 of the rack 8 away from the semicircular hole 4 is inclined relative to the reference plane of the rack, and the second side tooth surface 82 of the rack 8 close to the semicircular hole 4 is perpendicular to the reference plane of the rack, so that the tooth tips are inclined toward the semicircular hole 4. Guide bars 9 are respectively provided on the left and right sides of a pair of racks 8 on the inner side of each shell 3. The guide bars 9 are parallel to the closing surfaces of the pair of shells 3. When the two shells 3 are closed together, the adjacent guide bars 9 corresponding to each other in the two shells 3 are spaced apart from each other to form a moving channel 11 for the slider 2.

[0025] See also Figure 7The half-section schematic diagram shows that the slider 2 includes two symmetrical pressing blocks 10 and a frame 15 surrounding the pressing blocks 10. The end of the frame 15 close to the semicircular hole 4 of the shell 3 and the end of the frame 15 away from the semicircular hole 4 of the shell 3 are penetrated by a channel 16 arranged along the length direction of the shell 3, see Figure 3 As shown, the left and right sides of the pressing block 10 are also provided with L-shaped folded edges 13 facing the guide strip 9, and a U-shaped groove 14 with a width greater than the thickness of the guide strip 9 is formed between the opposite sides of the two pressing blocks 10 and the L-shaped folded edges 13 of the pressing blocks 10. The two guide strips 9 of each housing 3 are respectively embedded in the left and right U-shaped grooves 14 of a pressing block 10, which are used to keep the pressing block 10 from turning with the housing 3 and moving along the guide strip 9 in the housing 3. The frame 15 can be accommodated in the moving channel 11, and the frame 15 is used to keep the two pressing blocks 10 moving synchronously along the guide strip 9. After the two housings 3 are closed, the two pressing blocks 10 are close to each other and can be accommodated in the moving channel 11, and the pressing blocks 10 can be separated from each other to form a gap, the thickness of which is not less than the thickness of the paste tube 5 when it is completely flattened, and the gap is matched with the completely flattened paste tube 5. Corresponding protrusions and depressions are provided between the opposite sides of the two pressing blocks 10.

[0026] A spring sheet 12 facing the rack 8 is provided on one side of the two pressing blocks 10 that are away from each other. The first end of the spring sheet 12 is close to the semicircular hole 4 and connected to the pressing block 10. The second end of the spring sheet 12 extends toward the rack 8 and is embedded between the tooth tips. The spring sheet 12 is inclined relative to the surface of the pressing block 10. When the side of the two pressing blocks 10 that are away from each other is close to the guide bar 9, the angle between the spring sheet 12 and the surface of the pressing block 10 is reduced. When the side of the two pressing blocks 10 that are away from each other is separated from the guide bar 9, the angle between the spring sheet 12 and the surface of the pressing block 10 is increased.

[0027] like Figure 5 A and Figure 5As shown in FIG. 1B , when the symmetrical paste extruder is used, the shell 3 is opened, and the two pressing blocks 10 are slid along the guide strips 9 of each shell 3 to the end of each shell 3 away from the semicircular hole 4, and the tail end of the paste tube 5 is passed through the channel 16 of the frame 15, and then placed in one shell 3, and the two shells 3 are closed, so that the two pressing blocks 10 are embedded in the frame 15, and the two pressing blocks 10 press the bottom of the paste tube 5. When the two shells 3 are pressed, the two pressing blocks 10 are pressed due to the pressing force. The ointment in the paste tube is squeezed out. Since the second side tooth surface 82 of the rack 8 prevents the spring piece 12 from moving toward the end of the shell 3 away from the semicircular hole 4, when the two shells 3 are closed, the guide bar 9 in the shell 3 approaches the guide bar 9 in the other shell 3, and the guide bar 9 approaches the surface of the pressing block 10, and the angle between the spring piece 12 and the surface of the pressing block 10 becomes smaller, so that the two pressing blocks 10 slide along the surface of the paste tube 5 toward the extruder 6, and the two pressing blocks 10 are squeezed out of the tooth marks on the surface of the paste tube 5. When the two shells 3 are loosened, the tooth marks on the surface of the paste tube 5 can still be coupled with the protrusions or depressions of the pressing block 10 when the two shells 3 are separated, preventing the spring piece 12 embedded in the rack 8 from pushing the pressing block 10 to slide toward the end of the paste tube 5 away from the extruder head 6 when the angle between the spring piece 12 and the surface of the pressing block 10 increases. Therefore, as the angle between the spring piece 12 and the surface of the pressing block 10 increases, the second end of the spring piece 12 slides toward the tooth tip along the first side tooth surface 81 of the rack 8 and moves to the next tooth root closer to the semicircular hole 4 of the shell 3. When the two shells 3 are pressed next time, the second side tooth surface 81 of the rack 8 The surface 82 prevents the spring piece 12 from moving toward the end of the shell 3 away from the semicircular hole 4. The guide bar 9 in the shell 3 approaches the guide bar 9 in the other shell 3. The angle between the spring piece 12 and the surface of the pressing block 10 becomes smaller, so that the two pressing blocks 10 slide along the surface of the paste tube 5 toward the extruder head 6. The change in the angle between the spring piece 12 and the surface of the pressing block 10 during the sliding causes the sliding distance of the pressing block 10 along the surface of the paste tube 5 to change to a fixed distance, which can ensure the quantitative extrusion amount. The tooth tip of the rack 8 faces the semicircular hole 4 of the shell 3, so that the slider 2 can only move toward the semicircular hole 4 of the shell 3 and does not retreat.

[0028] The symmetrical ointment extruder provided by the present invention realizes quantitative extrusion of ointment through the up and down movement of a slider and the meshing of an elastic body and a rack. It has a simple structure and is easy for patients to squeeze out the ointment themselves without visual inspection, so that patients can squeeze out as much ointment in the ointment tube as possible without any residue. At the same time, the extrusion amount is accurate each time, so the ointment can be used a maximum number of times.
