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] Hemorrhoids can be treated with non-surgical treatments such as medication, injections, and physical therapy. Traditional Chinese medicine hemorrhoid ointment, for example, can reduce swelling, alleviate symptoms, and alleviate pain. Currently, commercially available hemorrhoid ointment comes in a small 4g tube. Generally, one tube can be used three to four times, and patients typically use it for seven consecutive days. If it's ineffective, further evaluation or a different medication is recommended. However, after the ointment is squeezed out of the tube, it's difficult to squeeze out all the remaining ointment. The less ointment there is, the harder it is to control the amount squeezed out. Due to the specific application area, patients prefer to apply the ointment themselves. When the tube is low and difficult to squeeze out, it's difficult for patients to verify that they've squeezed out enough, which can affect efficacy. Furthermore, due to the difficulty in applying the ointment, patients often discard tubes with some remaining ointment, resulting in significant waste and environmental pollution. Furthermore, a tube can only be used two to three times, requiring three to four tubes for seven consecutive days, leaving a significant amount of ointment left in the last tube. Therefore, in the care of hemorrhoids, there is a need for an ointment squeezer that is simple and easy for patients to operate themselves under non-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 uses of the ointment. Summary of the Invention

[0003] In response to the shortcomings of the existing technology, 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 convenient for patients to squeeze out as much ointment as possible from the ointment tube without residue.

One end of the two shells is hinged to each other, and the two shells are each provided with a semicircular hole corresponding to each other on the same end surface. The two shells are provided with racks arranged along the length direction on opposite sides of the two shells. The first side tooth surface of the rack away from the semicircular hole is inclined relative to the rack reference plane, and the second side tooth surface of the rack close to the semicircular hole is perpendicular to the rack reference plane, so that the tooth tips are inclined toward the semicircular hole.

[0006] Guide bars parallel to each other are provided inside each housing and on the left and right sides of the rack, and the guide bars are parallel to the closing surface of the pair of housings.

After the two shells 3 are folded, 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 the gap is not less than the thickness of the paste tube 5 when the paste tube 5 is completely flattened, and the gap cooperates with the completely flattened paste tube 5. The opposite sides of the two pressing blocks 10 are provided with corresponding protrusions and recesses.

[0026] The side of the two pressing blocks 10 away from each other is provided with a spring sheet 12 opposite to the rack 8, the first end of the spring sheet 12 is close to the semicircular hole 4 and connected with the pressing block 10, the second end of the spring sheet 12 extends to the rack 8 and is embedded between the teeth, the spring sheet 12 is inclined to the surface of the pressing block 10, when the side of the two pressing blocks 10 away from each other is close to the guide strips 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 away from each other is separated from the guide strips 9, the angle between the spring sheet 12 and the surface of the pressing block 10 is increased.

[0027] As shown in Fig. 5, the left and right sides of the pressing block 10 are also provided with L-shaped folded edges 13 facing the guide strips 9, the side of the two pressing blocks 10 opposite to each other and the L-shaped folded edges 13 of the pressing block 10 form a U-shaped groove 14 with a width greater than the thickness of the guide strips 9, the two guide strips 9 of each shell 3 are respectively embedded in the left and right U-shaped grooves 14 of one pressing block 10, for keeping the pressing block 10 able to turn with the shell 3 and move along the guide strips 9 in the shell 3, the frame 15 can be accommodated in the moving channel 11, the frame 15 is used for keeping the two pressing blocks 10 moving along the guide strips 9 synchronously. After the two shells 3 are folded, 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 the gap is not less than the thickness of the paste tube 5 when the paste tube 5 is completely flattened, and the gap cooperates with the completely flattened paste tube 5. The opposite sides of the two pressing blocks 10 are provided with corresponding protrusions and recesses. Figure 5 Figure 5 ​As shown in B in the figure, when the symmetrical ointment extruder is used, open the two housings 3, slide the two pressing blocks 10 along the guide strips 9 in the housings 3 to the ends of the housings 3 away from the semicircular holes 4, pass the tail end of the ointment tube 5 through the passage 16 of the frame 15, and then put the ointment tube 5 into one of the housings 3. Close the two housings 3, so that the two pressing blocks 10 are embedded in the frame 15, and the two pressing blocks 10 press the bottom of the ointment tube 5. When the two housings 3 are pressed, the two pressing blocks 10 extrude the ointment in the ointment tube 5, because the second side tooth surface 82 of the rack 8 prevents the spring piece 12 from moving to the end of the housing 3 away from the semicircular hole 4, when the two housings 3 are closed, the guide strip 9 in one of the housings 3 moves close to the guide strip 9 in the other housing 3, and the guide strip 9 moves close to the surface of the pressing block 10, 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 ointment tube 5 to the extrusion head 6, and the two pressing blocks 10 extrude tooth marks on the surface of the ointment tube 5. When the two housings 3 are opened, the tooth marks on the surface of the ointment tube 5 can still couple with the protrusions or depressions of the pressing blocks 10 when the two housings 3 are separated, preventing the spring piece 12 embedded in the rack 8 from pushing the pressing block 10 to slide to the end of the ointment tube 5 away from the extrusion 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 along the first side tooth surface 81 of the rack 8 to the tooth root of the next tooth closer to the semicircular hole 4 of the housing 3. When the two housings 3 are pressed again, the second side tooth surface 82 of the rack 8 prevents the spring piece 12 from moving to the end of the housing 3 away from the semicircular hole 4, the guide strip 9 in one of the housings 3 moves close to the guide strip 9 in the other housing 3, 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 ointment tube 5 to the extrusion head 6. The change in the angle between the spring piece 12 and the surface of the pressing block 10 during the sliding of the two pressing blocks 10 along the surface of the ointment tube 5 causes the change in the sliding distance of the pressing block 10 along the surface of the ointment tube 5 to be a fixed distance, which can ensure the quantity of the extruded ointment to be constant, and the tooth tip of the rack 8 faces the semicircular hole 4 of the housing 3, so that the slider 2 can only move to the semicircular hole 4 of the housing 3 and cannot move back.

[0028] The symmetrical ointment extruder provided by the application can realize the quantitative extrusion of ointment through the up-down movement of the slider and the engagement of the elastic body and the rack, has a simple structure, is easy for patients to extrude ointment under non-visual conditions, can extrude as much ointment as possible from the ointment tube, does not leave any ointment, and can accurately extrude the ointment each time to maximize the use of the ointment.
