The hemorrhoid part is positioned at the anus, so that the observation is difficult and the application of force is inconvenient during the application of the medicine, so that the dosage can not be accurately controlled when the medicine applicator is used, and the condition of excessive administration caused by excessive force often occurs due to the inconvenient application of the force. Meanwhile, because the end of the administration device is sharp, if the force is applied too much, the hemorrhoid part is easy to prick.

In order to solve the problems existing in the prior art, the utility model provides a drug feeder for hemorrhoids treatment. As shown in fig. 1 and 2, the dispenser includes: a medicine storage tube 10, an application tube 20, an extrusion tube 30 and a medicine pushing piston 40.

Specifically, referring to fig. 3 to 5, the ointment for treating hemorrhoids is stored in the drug storage tube 10. The bottom end of the medicine storage tube 10 is connected with the smearing tube 20, the top end of the medicine storage tube 10 is rotatably connected with the extrusion tube 30, and the medicine pushing piston 40 is arranged in the medicine storage tube 10. An annular part 31 is arranged at one end of the extrusion tube 30 close to the medicine storage tube 10, and the side inner wall of the annular part 31 is provided with an internal thread 311. The pushing piston 40 includes a piston portion 41 and a pushing rod 42 vertically connected to the center of the top surface of the piston portion 41.

The pushing rod 42 is provided with an external thread 421 on the circumferential surface thereof, the pushing rod 42 is inserted into the annular portion 31, and the external thread 421 on the pushing rod 42 is fitted with the internal thread 311 on the extruding pipe 30. When the squeezing tube 30 is rotated, the internal thread 311 and the external thread 421 rotate relatively, so that the pushing rod 42 drives the piston portion 41 to slide along the length direction of the medicine storage tube 10, and the ointment is squeezed out from the end of the applying tube 20 and applied to the hemorrhoid. Compared with a general push type administration device, the administration device for hemorrhoid treatment increases the motion stroke during administration through rotation, thereby reducing the administration speed, facilitating uniform administration and preventing the condition of excessive administration caused by over-force. In order to prevent the medicine pushing piston 40 from rotating circumferentially during sliding, and further cause the medicine pushing piston 40 to rotate along with the squeezing tube 30, so that the ointment cannot be squeezed out. The side of the piston part 41 is provided with a plurality of sliding grooves 411, the inner wall of the side of the drug storage tube 10 is provided with a plurality of sliding rails 11 matched with the sliding grooves 411, the number of the sliding rails 11 is equal to that of the sliding grooves 411, the width of the sliding rails 11 is equal to the width of the sliding grooves 411, and in actual application, the width of the sliding rails 11 is slightly smaller than the width of the sliding grooves 411. The slide rail 11 is disposed in the slide slot 411. By this arrangement, the piston portion 41 can only slide in the longitudinal direction of the drug storage tube 10 without rotating in the circumferential direction, and the drug pushing piston 40 is circumferentially restricted. When the extrusion tube 30 is rotated, the external thread 421 on the push rod 42 moves relative to the internal thread 311 on the extrusion tube 30, and the push rod 42 cannot rotate and can only slide along the drug storage tube 10, so that the push rod 42 pushes the piston part 41 to slide.

Referring to fig. 3 and 5, the end of the inner wall of the side of the drug storage tube 10 close to the extrusion tube 30 in the present embodiment is provided with an annular rotating groove 12, one end of the extrusion tube 30 close to the drug storage tube 10 is provided with an annular inward-contracting portion 32, and the end of the inward-contracting portion 32 far from the extrusion tube 30 is connected with an annular tapered portion 33.

The outer diameter of the bottom end of the conical part 33 is slightly smaller than the inner diameter of the medicine storage tube 10, the diameter of the top end of the conical part 33 is larger than the inner diameter of the medicine storage tube 10 and is also slightly smaller than the maximum diameter of the rotary groove 12; the thickness of the tapered portion 33 is slightly smaller than the groove width of the rotation groove 12. When assembling the administration device, the tapered portion 33 is inserted into the drug storage tube 10 so that the tapered portion 33 is positioned in the rotation groove 12. The rotary connection between the extrusion tube 30 and the medicine storage tube 10 is realized through the arrangement, and the medicine pushing piston 40 slides along the medicine storage tube 10 to extrude the ointment by rotating the extrusion tube 30.

In order to observe the residual amount of the ointment in the medicine storage tube 10, referring to fig. 3, an observation groove 13 is further formed on the outer wall of the side surface of the medicine storage tube 10, and the length direction of the observation groove 13 is parallel to the length direction of the medicine storage tube 10; the body of the observation tank 13 is transparent. The residual amount of the ointment in the main tube can be observed through the observation groove 13, and the ointment is added in time when the ointment is insufficient.

In order to control the dose, in a further embodiment, in conjunction with fig. 3 and 5, the bottom end of the squeeze tube 30 is provided with a hemispherical protrusion 34; meanwhile, the top end of the medicine storage tube 10 is provided with a concave part 14, and the convex part 34 is positioned in the concave part 14. When the squeeze tube 30 is rotated one revolution, the protrusion 34 slides along the top end of the drug storage tube 10 one revolution and slides back into the recess 14. The number of revolutions of the extruded tube 30 can be determined by the number of times the projection 34 slides into the recess 14, thereby achieving control of the dose. In this process, the patient may clearly feel the vibration when the convex portion 34 enters the concave portion 14 and hear the sound when the convex portion 34 enters the concave portion 14, and the dose amount can be accurately determined even in a case where observation is inconvenient in the application process.

Since the hemorrhoid is located at the anal region, when the applicator is used to apply the drug, the applicator tube 20 is contaminated, which is disadvantageous for long-term use, and the cost is increased when the applicator is directly replaced.

The limiting groove 15 comprises a first straight groove 151 along the length direction of the medicine storage tube 10 and a second straight groove 152 along the circumferential direction of the medicine storage tube 10, one end of the first straight groove 151 extends downwards to the end of the medicine storage tube 10, and the other end of the first straight groove 151 is directly connected with the end of the second straight groove 152. When the smearing pipe 20 is connected with the medicine storage pipe 10, the limiting block 21 is opposite to the first straight groove 151, the smearing pipe 20 is pushed to enable the limiting block 21 to slide to the end portion, close to the first straight groove, of the first straight groove 151 along the first straight groove 151, and then the smearing pipe 20 or the medicine storage pipe 10 is rotated to enable the limiting block 21 to slide to the end portion, far away from the first straight groove 151, of the second straight groove 152 along the second straight groove 152. When the smearing tube 20 needs to be taken down after the administration device is used, the smearing tube 20 or the medicine storage tube 10 is rotated reversely so that the limiting block 21 slides to the first straight groove 151 along the second straight groove 152, and then the smearing tube 20 is pulled out. The smearing pipe 20 and the medicine storage pipe 10 are detachably connected through the arrangement, the smearing pipe 20 is convenient to replace, the whole medicine feeder does not need to be replaced, and therefore the using cost of the medicine feeder is reduced. In addition, when the applying tube 20 is detached, ointment can be injected into the medicine storing tube 10.
