Abstract
Description
Technical Field
[0001] The utility model belongs to the field of medical instruments, and in particular relates to an ointment extruder with a protective shell and an extrusion tube. 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. Utility Model Content
[0003] In view of the deficiencies of the prior art, the utility model provides a solution with a simple structure and easy operation to meet the needs of hemorrhoid patients in self-treatment. The following are the main features and working principles of the ointment extruder: an ointment extruder with a protective shell and an extrusion tube, comprising a protective shell and a slider. The protective shell comprises two mutually closed shells, which form a cavity for accommodating the ointment tube after the two shells are closed. One end of the two shells is hinged to each other, and the other end can be rotated relative to the hinged end to allow opening and closing. Semicircular holes are provided on the hinged end faces of the two shells. When the two shells are closed, the two semicircular holes are closed to form a complete through hole, which is used to pass the upper end extrusion head of the ointment tube.
[0004] On the outer side surface of one of the shells, a slide groove is arranged in the center along the length direction of the shell, and the slide groove forms a moving channel for the slider to be installed and slide. The slider includes a pressing block and a push button. The pressing block is inside the protective shell and the side of the pressing block facing away from the push button is in contact with the ointment tube. The push button is arranged outside the center seam of the protective shell. A connecting part is provided between the pressing block and the push button, and the connecting part is embedded in the moving channel.
[0005] An accommodating space is formed between the pressing block and the inner side surface of the other shell body, and the thickness of the accommodating space is equal to the thickness of the paste tube when it is completely flattened, ensuring clearance fit with the completely flattened paste tube.
[0006] The two sides of the slide groove are symmetrically arranged with card slots along the length direction. The pressure block and the push button are connected by a connecting pipe. Elastic bodies are arranged on both sides of the connecting pipe. The elastic bodies can move along the slide groove and can be embedded in the card slot to prevent the connecting pipe from moving along the slide groove.
[0007] Preferably, the pressing block is provided with an extrusion hole, the central axis of which is parallel to the length direction of the cavity. The tail of the ointment is placed at the center of the extrusion hole, and the shape of the extrusion hole is slightly larger than the cross section of the ointment tube when the interior is emptied.
[0008] The ends of the two shells away from the hinged ends are respectively provided with a bayonet and a clip. When the two shells are brought close to each other, the bayonet and the clip can be locked with each other.
[0009] The pressing block is provided with protruding parts on both sides, which can move along the sliding strip inside the protective shell.
[0010] At least one shell is provided with a rack along the length direction on the side facing the cavity, the tooth tip of the rack is designed to face the semicircular hole, and the pressing block is provided with teeth meshing with the rack. For example, the rack is attached to the side of the slide facing the cavity, and the protruding parts on both sides of the pressing block are provided with teeth meshing with the rack, and the tooth tip of the rack is designed to face the semicircular hole.
[0011] In summary, the design of the ointment extruder of the utility model fully considers the convenience of use for patients, the accuracy of dosage and the environmental friendliness of operation, and is expected to provide a more efficient, economical and hygienic treatment plan for hemorrhoid patients.
[0012] Compared with the prior art, the beneficial effect of the utility model is that quantitative extrusion of the ointment is achieved by the up and down movement of the slider and the cooperation of the elastomer and the slot or the meshing of the rack and the teeth. The utility model has a simple structure and is easy for patients to extrude the ointment themselves without visual conditions, so that patients can squeeze out as much ointment as possible from the ointment tube without residue. At the same time, the amount extruded each time is accurate, so the ointment can be used to the maximum extent possible. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the invention objectives, technical solutions and invention advantages of the utility model more clear, the utility model will be described in detail below with reference to the accompanying drawings.
[0018] Example 1
[0019] like Figure 1 (a), (b), (c) and Figure 2 As shown, the paste extruder includes a protective shell 1 and a slider 2. The protective shell 1 includes two mutually closed shells 3, one end of the two shells 3 is hinged to each other, and the other end can rotate relative to the hinged end to allow opening and closing. Semicircular holes 4 are provided on the hinged end faces or non-hinged sections of the two shells 3. When the two shells 3 are closed, the two semicircular holes 4 are closed to form a complete through hole, which is used to pass the upper end extrusion head 6 of the ointment tube 5. After the two shells 3 are closed, a cavity containing the ointment tube 5 is formed.
[0020] On the outer side surface of one of the shells 3, a center seam 7 is arranged in the center along the length direction of the shell 3. The center seam 7 penetrates the inner and outer surfaces of the shell 3 to form a moving channel for the slider 2 to be installed and slide.
[0021] like Figure 3 As shown, the slider 2 includes a pressing block 8 and a push button 9. The side of the pressing block 8 facing away from the push button 9 contacts the ointment tube 5. The push button 9 is placed outside the middle seam 7 of the protective shell 1. A connecting portion 12 is provided between the pressing block 8 and the push button 9. The connecting portion 12 is embedded in the moving channel. An accommodating space is formed between the pressing block 8 and the inner side surface of the other shell 3. The thickness of the accommodating space is equal to the thickness of the ointment tube 5 when it is completely flattened, ensuring clearance fit with the completely flattened ointment tube 5.
[0022] The ointment tube 5 will be placed in the shell 3, and the pressing block 8 begins to press the bottom of the ointment tube 5 away from the semicircular hole 4. As the push button 9 moves along the middle seam 7 from away from the semicircular hole 4 to close to the semicircular hole 4, the ointment inside the ointment 5 is gradually squeezed to the upper extrusion head 6.
[0023] In order to further improve the practicality of the utility model, the following improvements have been made:
[0024] like Figure 4 As shown, mutually locking bayonet holes 17 and clips are added on opposite sides of the housing 3 to ensure that the two housings 3 are not easily separated after being closed.
[0025] When the two shells 3 are closed, the gap between the ends of the two shells 3 away from the semicircular hole 4 is smaller than the thickness of the ointment tube 5 when it is completely flattened, thereby clamping the flat portion of the lower end of the ointment tube 5.
[0026] The method of using the paste extruder is simple and clear: first open the housing 3, slide the slider 2 to the end away from the semicircular hole 4, then put the ointment tube 5 into one housing 3, and close the two housings 3. Then, push the push button 9 extending from the middle seam 7 to the outside of the clamp, and slide the push button 9 to drive the slider 2 to move.
[0027] Example 2
[0028] like Figure 4 As shown, on the basis of Example 1, the pressing block 8 is provided with an extrusion hole 10, the central axis of the extrusion hole 10 is parallel to the length direction of the cavity, and the inner cross section of the extrusion hole 10 is larger than the cross section of the ointment tube 5 after being emptied. The tail of the ointment tube 5 is placed in the extrusion hole 10. By sliding the push button 9 from the end away from the semicircular hole 4 to the end close to the semicircular hole 4, the protruding parts 15 on both sides of the pressing block 8 move along the sliding strip 16 inside the protective shell 1, and the ointment inside the ointment tube 5 is gradually squeezed to the upper end extrusion head 6.
[0029] As an improved manner, at least one shell 3 is provided with a rack along the length direction on the side facing the cavity, the tooth tip of the rack is designed to face the semicircular hole 4, and the pressing block 8 is provided with teeth meshing with the rack.
[0030] For example, a rack is attached to the side of the slide bar 16 facing the cavity, and the protruding parts on both sides of the pressing block are provided with teeth meshing with the rack, and the tooth tips of the rack are designed to face the semicircular hole 4. In this way, when the two sides of the slide groove are not provided with the clamping groove 11, and the two sides of the connecting tube 12 are not provided with the elastic body 13, the engagement between the rack and the teeth can also make the slider only slide one-way by the teeth when the protective shell is closed, which is conducive to quantitatively squeezing the ointment inside the ointment tube 5.
[0031] The ointment extruder provided by the utility model realizes the extrusion of ointment by moving the slider up and down. It is not only simple in structure and convenient for patients to operate without visual conditions, but also can ensure that as much ointment as possible in the ointment tube is squeezed out without residue. Due to the design of the protective shell, the internal fixture and other designs can be effectively protected. At the same time, due to the small caliber of the upper end extrusion head, the accuracy of the amount of extruded ointment can be controlled to the maximum extent.
