Description

Technical Field

[0001] The invention belongs to the field of medical devices, and in particular relates to an 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 an ointment extrusion device with a simple structure, which is easy for patients to extrude 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 to the maximum number of times.

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

[0005] A paste extrusion device, comprising a clamp and a slider, wherein the clamp is composed of two shells, the inner side surfaces of the two shells are both grooved surfaces, the upper ends of the two shells are hinged to each other, and the upper end surfaces of the two shells are respectively provided with semicircular holes corresponding to each other; racks are arranged in the middle of the two shells along the length direction, and the tooth tips of the racks are inclined toward the semicircular holes, and two rows of guide bars are also arranged inside one of the shells, the guide bars are parallel to the closing surfaces of the two shells, and the two rows of guide bars are respectively located on the opposite sides of a pair of racks;

[0006] The slider is hinged in sequence by the pressing plate, pressing block 1, and pressing block 2, which are constructed into a folded "J"-shaped structure and can be accommodated between two shells. The lower ends of pressing block 2 and pressing block 1 are hinged to each other and are far away from the semicircular hole in the fixture. The upper ends of the pressing plate and pressing block 1 are hinged to each other and are close to the semicircular hole in the fixture. The front side of pressing block 2 faces the shell provided with a guide strip, and the rear side of pressing block 2 faces pressing block 1. The left and right sides of pressing block 2 are respectively connected with L-shaped flanges. The L-shaped flanges form a gap for accommodating the guide strip on the left and right sides of pressing block 2, and the gap is greater than the thickness of the guide strip. The front side of pressing block 2 is connected with an elastic plate, which extends from the upper end of pressing block 2 and bends to the lower end. The end of the elastic plate away from the semicircular hole can be embedded between the tooth tips of the rack of the shell provided with the guide strip, and the lower end of the pressing plate extends toward the rack of the other shell and is embedded between the tooth tips. The pressing plate is also restricted by a limiting structure to keep a constant distance between the shells close to it.

[0007] An elastic body is also provided between the hinged ends of the two shells or between the first and second pressing blocks and the pressing plate, and is used to drive the two shells to open.

[0008] Preferably, both shells are provided with a center seam centered along the length direction, and racks are provided on the left and right sides of the center seam of each shell, respectively. The limiting structure includes a fin plate provided on the side of the pressure plate facing away from the pressure block 2, and the fin plate extends from the center seam of the shell close to the pressure plate to the outside of the shell, and wing plates are provided on the left and right sides of the fin plate, the width of the wing plate is greater than the width of the center seam, and the spacing between the wing plate and the pressure plate is equal to the thickness of the shell close to the pressure plate.

[0009] Preferably, the wing plate is rotatably connected to a side of the fin plate away from the pressure plate.

[0010] Preferably, a fin is centrally arranged on one side of the pressing block 2 facing the shell provided with the guide strip, and the fin extends from the middle seam to the outside of the shell provided with the guide strip.

[0011] Preferably, the lower end of the pressing block 2 and the left and right sides of the upper end of the pressing block 1 are symmetrically provided with ear plates facing the pressing plate, the lower end of the pressing block 1 is rotatably connected to the ear plates of the pressing block 2, and the ear plates of the pressing block 1 are rotatably connected to the upper end of the pressing plate.

[0012] Preferably, the first side tooth surface of the rack away from the semicircular hole is inclined relative to the reference plane of the rack, and the second side tooth surface of the rack close to the semicircular hole is perpendicular to the reference plane of the rack, so that the tooth tips are inclined toward the semicircular hole.

[0013] The ointment extrusion device provided by the present invention, when assembled: open two shells, insert the second pressing block of the slider between the guide strips of the shells, and the lower end of the elastic plate is away from the semicircular hole, bring the pressing plate of the slider close to the other shell, the fin plate passes through the shell, slide the slider to the end away from the semicircular hole, and then rotate the wing plate on the fin plate to make the pressing plate engage with the shell, put the paste tube between the two shells, the extrusion head of the paste tube passes through the semicircular hole, and the tail of the paste tube is placed between the first pressing block and the second pressing block.

[0014] When operating to extrude the ointment, close the two shells, squeeze the ointment at the tail of the ointment tube from the extruder, and after loosening the two shells, the pressure plate and the shell close to it keep the same distance, and the second pressure block keeps parallel to the guide strip in the other shell and moves with the shell, so that the first pressure block and the second pressure block are opened, and the first pressure block rotates relative to the pressure plate. Since the gap for accommodating the guide strip formed by the L-shaped flange on the left and right sides of the second pressure block is larger than the thickness of the guide strip, the second pressure block is slightly separated from the adjacent shell. Since the clamp of the first pressure block, the second pressure block and the pressure plate becomes larger, and the rack prevents the pressure plate from moving away from the semi-closed pressure block. The movement in the direction of the circular hole shortens the projection distance of the pressure block 1 in the length direction of the paste tube, which is equivalent to the pressure block 1 pushing the pressure block 2 to slide in the direction of the semicircular hole, so that the elastic plate slides along the rack by a set number of teeth in the direction of the semicircular hole; when the two shells are closed again, the pressure block 2 drives the pressure block 1 and the pressure plate to slide in the direction of the semicircular hole, and the pressure plate also slides along the rack by a set number of teeth in the direction of the semicircular hole, so that the slider moves as a whole and squeezes the paste tube between the pressure blocks 1 and 2. During the sliding, the elastic plate engages with the rack to ensure the quantitative extrusion amount, and the tooth tip faces the semicircular hole, so that the slider can only move toward the semicircular hole.

[0015] The present invention is based on the meshing of the elastic plate and the rack. The operator can achieve quantitative extrusion of the ointment by pressing the shell in a blind state, thereby achieving the movement of the slider. The structure is simple, and it is easy for the patient to extrude the ointment by himself in a blind state, so that the patient 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. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] 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.

[0025] 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.

[0026] like Figure 1-Figure 2 The ointment extrusion device shown includes a clamp 1 and a slider 7. The clamp 1 is composed of a shell 1 2 and a shell 2 3. The inner side surfaces of the shell 1 2 and the shell 2 3 are constructed as groove surfaces for accommodating the paste tube 17. The upper ends of the shell 1 2 and the shell 2 3 are hinged to each other. The shell 1 2 and the shell 2 3 are respectively provided with corresponding semicircular holes 4 on the upper end surfaces; when the shell 1 2 and the shell 2 3 are closed together, a columnar space for accommodating the paste tube 17 is formed between the opposite sides thereof, and the two semicircular holes 4 are closed to each other to form a through hole, as shown in FIG. Figure 4 As shown, the extruder head 18 at the upper end of the paste tube 17 passes through between the two semicircular holes 4, and the shell 1 2 and the shell 2 3 are both provided with a center seam 5 in the center along the length direction; the inner sides of the shell 1 2 and the shell 2 3 are also provided with a row of racks 6 on the left and right sides of the center seam 5, respectively, and the racks 6 are parallel to the center seam 5, and the first side tooth surface 61 of the rack 6 away from the semicircular hole 4 is inclined relative to the reference plane of the rack 6, and the second side tooth surface 62 of the rack 6 close to the semicircular hole 4 is perpendicular to the reference plane of the rack 6, so that the tooth tips are inclined toward the semicircular hole 4; Figure 2 As shown, two rows of guide bars 16 are also provided inside the shell 2 3, and the guide bars 16 are parallel to the closing surface of the shell 1 2 and the shell 2 3, and the two rows of guide bars 16 are respectively located on the opposite sides of a pair of racks 6. An elastic body is also provided between the hinged ends of the two shells or the pressure block 1 8 and the pressure block 2 9 and the pressure plate 14, which is used to drive the two shells to open.

[0027] like Figure 3-Figure 4As shown, the slider 7 is constructed into a folded "J"-shaped structure by the pressure plate 14, pressure block 1 8, and pressure block 2 9 which are hinged in sequence. The lower ends of pressure block 2 9 and pressure block 1 8 are hinged to each other and are far away from the semicircular hole 4 in the fixture 1. The upper ends of the pressure plate 14 and pressure block 1 8 are hinged to each other and are close to the semicircular hole 4 in the fixture 1. The front side of pressure block 2 9 faces the shell body 2 3, and the rear side of pressure block 2 9 faces pressure block 1 8. After the pressure plate 14, pressure block 1 8 and pressure block 2 9 are brought close to each other, the slider 7 can be accommodated in the columnar space. The left and right sides of the pressing block 2 9 are connected to the L-shaped flange 12 embedded between the guide bar 16 and the shell 2 3. The gap formed by the L-shaped flange 12 on the left and right sides of the pressing block 2 9 to accommodate the guide bar 16 is larger than the thickness of the guide bar 16. The front side of the pressing block 2 9 is connected to the elastic plate 10, which extends from the upper end of the pressing block 2 9 and bends toward the lower end. The end of the elastic plate 10 away from the semicircular hole 4 can be embedded between the tooth tips of the rack 6 of the shell 2 3. The lower end of the pressing plate 14 extends toward the rack 6 of the shell 1 2 and is embedded between the tooth tips.

[0028] A fin 15 is provided on the side of the pressure plate 14 facing away from the pressure block 2 9 , and the fin 15 extends from the middle seam 5 of the shell 2 to the outside of the shell 2 , and wing plates 19 are provided on the left and right sides of the fin 15 , the width of the wing plates 19 is greater than the width of the middle seam 5 , and the spacing between the wing plates 19 and the pressure plate 14 is equal to the thickness of the shell 2 .

[0029] When the shell 1 2 and the shell 2 3 are relatively close to each other, the pressure plate 14, the pressure block 1 8 and the pressure block 2 9 are folded into a "J"-shaped structure, and the lower end of the pressure plate 14 and the end of the elastic plate 10 away from the semicircular hole 4 are respectively embedded between the tooth tips of the rack 6 of the shell 1 2 and the shell 2 3. When the shell 1 2 and the shell 2 3 are relatively opened, the pressure block 2 9 remains parallel to the guide bar 16, so it moves with the shell 2 3 and is slightly separated. The pressure plate 14 rotates relative to the pressure block 1 8, and is restricted by the wing plate 19 on the fin plate 15 to keep the distance from the shell 2 unchanged.

[0030] Preferably, a fin 11 parallel to the middle seam 5 is centrally arranged on a side of the elastic plate 10 facing away from the second pressing block 9 , and the fin 11 extends from the middle seam 5 to the outside of the second pressing block 9 .

[0031] Preferably, the lower end of the pressing block 2 9 and the left and right sides of the upper end of the pressing block 1 8 are symmetrically provided with ear plates 13 facing the housing 1 2. The lower end of the pressing block 1 8 is rotatably connected to the ear plate 13 of the pressing block 2 9, and the upper end of the pressing plate 14 is rotatably connected between the ear plates 13 of the pressing block 1 8, such as Figure 6 As shown, a rotatable wing plate 19 is provided on the side of the fin plate 15 away from the pressure plate 14, and the distance between the wing plate 19 and the pressure plate 14 is equal to the thickness of the shell 2.

[0032] The method of using the paste extruder is as follows: open the shell 1 2 and the shell 2 3, insert the pressing block 2 9 of the slider 7 between the guide strips 16 of the shell 2 3, and the lower end of the elastic plate 10 is away from the semicircular hole 4 of the shell 2 3, bring the pressing plate 14 of the slider 7 close to the shell 1 2, and the fin plate 15 passes through the shell 1 2, slide the slider 7 to the end away from the semicircular hole 4, and then rotate the wing plate 19 on the fin plate 15 to make the pressing plate 14 engage with the shell 1 2, put the paste tube 17 between the shell 1 2 and the shell 2 3, the extrusion head 18 of the paste tube 17 passes through the semicircular hole 4, and the tail of the paste tube 17 is placed between the pressing block 1 8 and the pressing block 2 9.

[0033] like Figure 7 When the housing 1 2 is located at the top and the housing 2 3 is located at the bottom in the hand-held clamp 1, Figure 7 As shown in the upper part of the embodiment, close the shell 1 2 and the shell 2 3, squeeze the ointment at the tail of the paste tube 17 from the extrusion head 18, and loosen the shell 1 2 and the shell 2 3. Figure 7 As shown in the middle part, the pressure plate 14 and the shell 2 keep the same distance, the pressure block 29 remains parallel to the guide strip 16 in the shell 23 and moves with the shell 23, so that the pressure block 18 and the pressure block 29 are opened, and the pressure block 18 rotates relative to the pressure plate 14. Since the gap formed by the L-shaped flange 12 on the left and right sides of the pressure block 29 to accommodate the guide strip 16 is greater than the thickness of the guide strip 16, the pressure block 29 is slightly separated from the shell 23 at this time. Since the clamp of the pressure block 18, the pressure block 29 and the pressure plate 14 becomes larger, and the rack 6 prevents the pressure plate 14 from moving in the direction away from the semicircular hole 4, the projection distance of the pressure block 18 in the length direction of the paste tube 17 is When the shell 1 2 and the shell 2 3 are closed again, the pressing block 2 9 drives the pressing block 1 8 and the pressing plate 14 to slide in the direction of the semicircular hole 4, and the pressing plate 14 also slides in the direction of the semicircular hole 4 in the direction of the semicircular hole 4 in the direction of the set number of teeth along the rack 6 of the shell 1 2, so that the slider 7 moves as a whole and squeezes the paste tube 17 between the pressing block 1 8 and the pressing block 2 9. During the sliding, the elastic plate 10 is meshed with the rack 6 to ensure the quantitative extrusion amount, and the tooth tip faces the semicircular hole 4, so that the slider 7 can only move toward the semicircular hole 4.

[0034] like Figure 8 When the housing 1 2 of the hand-held fixture 1 is located at the bottom and the housing 2 3 is located at the top, Figure 7 The opening and closing processes of the middle shell 1 2 and the shell 2 3 are similar. Each time the shell 1 2 and the shell 2 3 are opened and closed, the slider 7 moves a certain distance toward the semicircular hole 4 and squeezes out a certain amount of ointment.

[0035] The ointment extrusion device provided by the present invention is based on the meshing of an elastic plate and a rack, and realizes quantitative extrusion of the ointment by pressing a shell to realize the movement of a slider. The structure is simple, and it is easy for patients to extrude the ointment themselves without visual inspection, so that patients can squeeze out as much ointment in the ointment tube as possible without residue. At the same time, the extrusion amount is accurate each time, so the ointment can be used a maximum number of times.
