Fig. 8 and 9 show a pair of through holes 13, each of which has an incomplete half-ring shape.

A medicine collecting part 2, wherein the medicine collecting part 2 is provided with an annular cavity 2b and an inner cylinder 2a coaxial with the annular cavity 2 b. As shown in fig. 1, the left end of the medicine collecting part 2 is connected to the right end of the housing main body 1, and the right end of the medicine collecting part 2 is formed with a port through which a rod case 01 and a coating rod 02 mentioned below are inserted and extended. The right end cavity of the annular cavity 2b is close to the axial center side (of the medicine collecting part 2), the radial width is gradually reduced, a medicine leakage opening corresponding to the right side of the port of the inner cylinder 2a is formed at the tail end of the right end, the medicine leakage opening can be annular seams or a plurality of annularly distributed holes, such as round holes, flat holes, taper holes and the like, such as continuous annular seams or discontinuous incomplete seams, and the seams or holes can be axially arranged into one layer or a plurality of layers. In short, the specific cavity form of the medicine leakage opening can be arranged in various modes and in various distribution modes. As shown in fig. 1 and 2, the drug outlet is not directly arranged on the inner wall of the annular cavity 2b, but is connected by other movable connecting parts. As shown in fig. 1, 2, 6 and 7, the embodiment:

the right end face of the inner cylinder 2a in the medicine collecting part 2 is contracted towards the axial inner side (left side) relative to the tail end of the cavity closing part of the annular cavity 2b to form an annular notch with a certain axial width, and the end face (right end) of the inner cylinder 2a is also provided with a conical surface sink groove. The ring chamber 2b ends open here. For setting up the medicine leakage mouth, placed ring A8 and ring B9 in the medicine portion 2 right port that gathers materials, and ring A8 is established the interior (left) side at ring B9 relatively, ring B9 with the port department threaded connection of medicine portion 2 that gathers materials has set up arris hole 9a for this reason on ring B9's right-hand member face to make things convenient for ring B9 to install in the port of medicine portion 2 that gathers materials, if of course ring B9 is partly to arrange the structure outside medicine portion 2 that gathers materials in, arris hole 9a can be removed. The rings A8 and B9 can block the annular gap formed at the end of the annular cavity 2B. As shown in fig. 2, the left end face of the ring A8 is provided with an annular flange matching with the conical sinking groove arranged on the inner cylinder 2a, and the outer wall of the annular flange is a conical ring surface 8 a. The outer wall of the ring A8 is provided with a radial groove which can be communicated with the annular cavity 2b, a colloid bag part is embedded in the groove, and a medicine leakage opening is arranged on the colloid bag part. In a specific embodiment, as shown in fig. 1 and 2, a radially extending annular groove is provided on the outer wall of the ring A8, the annular groove can communicate with the annular cavity 2b, and the annular groove is embedded with the colloid bag ring 81. The slit 81a of the colloidal sac ring 81 is the medicine leakage opening. During manufacture, the wall of the colloid sac ring 81 is as thin as possible, and the colloid sac ring is not in a tight state when being sleeved in the annular groove of the ring A8, but is loose as much as possible, so that a certain pressure is needed when the medicine seeps out from the seam 81 a. The slots 81a are shown as axially spaced layers. In the specific implementation, a layer of slits or annularly distributed holes are further arranged on the left side and/or the right side of the displayed slit 81 a. Of course, in other embodiments, the drug outlet may be provided directly on the inner wall of the annular chamber 2 b.

Compared with the embodiment in which the outlet is arranged directly in the inner wall of the annular chamber 2b, the embodiment in which it is arranged in the ring A8 is obviously more convenient to replace after the outlet is blocked. And according to the ointment consistency of difference, the shape, the size of the medicine mouth that leaks that sets up just require the diversification, and through the part that can dismantle this moment, it is obviously better. When the ring B9 is screwed into the port of the medicine collecting part 2, the ring B will push the conical ring surface 8a of the ring a8 to press tightly into the conical sinking groove on the right end surface of the inner cylinder 2a, so as to seal the gap on the right end of the annular cavity 2B.

And a connecting part 3, wherein the connecting part 3 is arranged between the shell main body 1 and the medicine collecting part 2, and the shell main body and the medicine collecting part are coaxially connected into a whole through a thread structure. It is not necessary to provide a structure, and the connecting portion 3 may be a spiral ring with threads at both ends in a specific embodiment, and the threads at both ends may be external threads or internal threads, or one end may be external threads and the other end may be internal threads. In a specific embodiment, as shown in fig. 1, 6, and 7, the connecting portion 3 may be a pair of double-ended screw rings, such as a double-ended screw ring first 31 and a double-ended screw ring second 32, one end of the double-ended screw ring first 31 is connected to the drug collecting portion 2, one end of the double-ended screw ring second 32 is connected to the housing main body 1, and through the threaded connection established between the other end of the double-ended screw ring first 31 and the other end of the double-ended screw ring second 32, the axial distance between the drug collecting portion 2 and the housing main body 1 can be adjusted, and further the installation effect of a component (such as the central tube 4) disposed between the drug collecting portion 2 and the interior of the housing main body 1 can be adjusted.

And the central tube 4 is opened at one end, closed at the other end, the opened end is inserted into the inner tube 2a and extends to the outer port of the inner tube 2a, and the closed end extends into the shell main body 1 and can form a fixed connection relation with the inner wall of the shell main body 1, namely, is connected with the internal thread arranged on the inner boss 1 a.

And a slider part 5, the slider part 5 being disposed in the cavity of the housing main body 1 and capable of reciprocating in the axial direction of the housing main body 1. As shown in fig. 1, 6, 17, 18: the slider portion 5 includes a column portion 5a and an arm portion 5b, and the column portion 5a is disposed in the first sinking chamber 11 and is capable of axially reciprocating therein. The arm 5b extends from the first chamber 11 to the second chamber 12 through a through hole 13 in a partition provided in the housing body 1. The arm portions 5b can shuttle on the left and right sides of the partition by means of the through holes 13.

The through holes 13 may be in the form of a plurality of holes distributed around the same circumference, in addition to the shown incomplete semi-ring form, in which case the corresponding arm portions 5b are cylindrical.

And one end of the push rod part 6 is provided with an annular plug 6a matched with the annular cavity 2b, and the other end of the push rod part 6 extends into the cavity of the shell main body 1 and is connected with one end of the sliding block part 5.

Thus, when the sliding block part 5 reciprocates along the axial direction of the shell main body 1, the push rod part 6 can be driven to synchronously and axially move, so that the ring part 61 can slide in the second sunken cavity 12 in a reciprocating way, and the annular plug 6a can selectively extend into or move out of the annular cavity 2 b. The stem 62 is shown in fig. 19 as being circular and in fig. 20 as being a plurality of posts distributed around the same circumference. In order to ensure uniform stress on the annular plug 6a, the rod part 62 shown in fig. 19 is preferred, but when the outer end (left end) face of the annular plug 6a is provided with a rigid ring member, the required stress effect on the annular plug 6a can be achieved by the method shown in fig. 20.

And the coating rod set comprises a rod sleeve 01 and a coating rod 02 arranged in the rod sleeve 01, wherein the rod sleeve 01 can be inserted into the central tube 4, and one end of the rod sleeve 01 arranged on the outer (right) side is opposite to the inner (left) side of a medicine leakage opening formed at the end part of the annular cavity 2b (right). As shown in fig. 4, one end of the coating rod 02 extends out of the rod sleeve 01, a handle 02a can be arranged, a sealing film 02b is arranged on the periphery of the coating rod 02 corresponding to the outlet of the rod sleeve 01, and the coating rod 02 is sealed in the rod sleeve 01 through the sealing film 02 b. In the embodiment shown in fig. 5, the coating rod 02 is covered with pile protrusions 02c, and in the embodiment, the pile protrusions 02c may be covered on the whole active outer wall of the coating rod in a wrapping manner (as shown in fig. 5), or may be covered on the whole active outer wall of the coating rod in a segmented manner in the axial direction, or may be spirally wound on the whole active outer wall of the coating rod. By "active outer wall" is meant the portion of the coating rod that is disposed within the rod sleeve. The applicator rod 02 is generally provided with a cotton wool layer which can be selectively retained or removed or partially retained when the pile protrusions 02c are provided. According to different conditions of illness, required dosage and the like, the coating rods 02 with different structures are selected to be used, for example, in a certain embodiment, the coating rods 02 are wrapped with a medicinal cotton layer, the plush protrusions 02c are partially wrapped on the medicinal cotton layer, and the plush protrusions 02c are wrapped on the outer wall of the coating rods 02 in a segmented mode along the axial direction of the coating rods 02, so that medicines can be placed between two adjacent sections of plush protrusions, and the medicines carried by the plush protrusions are less if the radial thickness of the plush protrusions is smaller. Otherwise, there will be relatively more. Of course, when the applicator 02 is not provided with the cotton wool layer, it is also possible to cover a pile projection on the surface thereof, and to provide a plurality of rings formed by the pile projections at a partial position in the axial direction, so that the medicine is concentrated between the two rings.

As shown in fig. 1, 12 to 14, the inner end of the inner tube 2a of the drug collecting part 2 is tapered. The central tube 4 is inserted into the outer wall of one end of the inner tube 2a and is contacted with the necking part of the inner tube 2a, and is in a conical surface shape. When the connection portion 3 is formed as a pair of the double threaded rings 31 and 32, the length of the portion where the double threaded rings 31 and 32 are engaged with each other can be adjusted to tightly engage the center tube 4 with the inner tube 2 a.

In the embodiment, in order to move the sleeve 01 out of the central tube 4, a certain resistance is overcome to prevent the coating rod group from randomly sliding off the device (i.e. from the right port of the medicine collecting part 2), and the coating rod 02 is taken out from the sleeve 01 in consideration of facilitating the connection between the sleeve 01 and the coating rod 02 to be removed during use. As shown in fig. 2, a radially extending protrusion 8b is disposed on the inner wall of the ring A8 and on a side opposite to the left end, and the protrusion 8b may be a plurality of protrusions distributed around the circumference, and the outer wall of the protrusion has an axially transitional arc surface. Correspondingly, the outer diameter of the rod sleeve 01 corresponding to the ring A8 is larger than the outer diameter of the part extending to the inner part of the central tube 4, and the outer wall of the section is provided with a clamping groove 01a matched with the clamping protrusion 8 b. When the clamping protrusion 8b and the clamping groove 01a are not arranged, the coating rod group is prevented from randomly sliding off from the device by means of the frictional resistance between the outer wall of the rod sleeve 01 and the wall of the containing cavity 41 of the central tube 4. In addition, after the arrangement of the associated structure of the clamping protrusion 8b matched with the clamping groove 01a, the coating rod group can be effectively prevented from sliding off the device at will, and the connection between the coating rod group and the sealing film 02b of the rod sleeve 01 can be released only by screwing the coating rod 02.

Under the scheme of this patent, scribble excellent 02 and be placed in stick cover 01 sealedly (stick cover inner chamber and scribble the stick and all carried out the sterilization before packing), transport, carry the in-process as long as the packing does not break just can not contact the external world, so can ensure its clean, health. Moreover, when the medicine is applied to the coating rod, the hands can not contact the action part of the coating rod at all, so that the sanitation of the process can be ensured. By controlling the moving speed and the moving interval of the sliding block part, the pushing speed of the pushing rod part to the annular plug and the time period length can be adjusted, and the medicine can be placed on the surface of the coating rod in a selected area in a fixed-point and quantitative mode.

Still further, after the application of the coating rod set, the rod case 01 is easily taken out from the central tube 4. As shown in fig. 6, 7, 10 and 11, a pair of longitudinal slots A1b are provided on the wall of the housing body 1 in a diametrically opposed manner. In the illustrated case, the inner end of the receiving cavity 41 of the central tube 4 extends to the left side of the partition board provided in the casing main body 1 and enters the axial hole of the inner boss 1a, so that a longitudinal slot a opposite to the pair of longitudinal slots A1b on the casing main body 1 is correspondingly provided on the wall body of the inner boss 1a, and the four longitudinal slots a can radially overlap. At this time, as shown in fig. 1, 3, and 14 to 16, a longitudinal groove B4a passing through in the radial direction is formed in the inner bottom of the cavity 41 of the center tube 4. The longitudinal slot A1B can communicate with the longitudinal slot B4a in the radial direction. The "longitudinal direction" in the longitudinal slot A1b means that the slot extends a certain length in the axial direction of the housing main body 1. By "longitudinal" in the longitudinal slot B4a, it is meant that the slot extends axially a certain depth from the inner bottom surface of the central tube 4. In this case, the slot includes a T-shaped portion 03 that is fitted to the

longitudinal slots

1b and 4 a. The T-shaped portion 03 includes a push rod 031 and a cross rod 032, one end of the push rod 031 extends into the longitudinal slot B4a, and the other end extends into the cavity 41 of the central tube 4.
