A sustained-release drug support release frame

Abstract

This utility model discloses a sustained-release drug support and release frame, including a top cover, a top tube welded to the outer edge of the bottom of the top cover, and a slot opened at the center of the outer wall of one side plate. By setting an exhaust pipe, the staff can create a negative pressure vacuum inside the support and release frame, which can release drugs for up to 6 months. The locking blocks on one set of support and release frames can be horizontally inserted into the inner wall of the slot on another set of support and release frames. In this way, multiple sets of identical support and release frames can be assembled together horizontally, thereby adjusting the circumferential size of the support and release frame. By assembling multiple sets of support and release frames together, the contact area between the surface of the support and the patient's tendon can be further expanded, thereby achieving a good support effect. The simple connection method between the locking blocks and the slot makes the installation of the support and release frame more convenient and quick, which not only saves the time of medical staff, but also improves the effectiveness of the sustained-release drug support.

Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a sustained-release drug support release frame. Background Technology

[0002] Tendon injuries can be treated with medication and physical therapy. However, tendon repair faces several challenges, including a shortage of repair cells and an imbalanced immune response. As a result, tendon injuries often result in scarring after healing, leading to poor function and decreased athletic performance.

[0003] Existing treatments for tendon injuries involve long recovery periods. While sustained-release drug-eluting stents are used for tendon repair, they often only store enough medication for a single injection, requiring frequent replacements. To address these issues, Chinese patent CN220046815U discloses a new sustained-release drug-eluting stent. This new stent features an elastic line with a drug-storing support box that slides along it. The support box is easily adjustable to the tendon injury site. Medication in the support box is used for the first application, and medication from the upper drug box is released for a second application. This reduces the frequency of stent replacements, allowing for two separate applications of medication to the tendon injury site, making treatment more convenient during the recovery period.

[0004] This sustained-release drug-eluting stent has only one set of stent body. After the stent body is installed at the site of the patient's tendon injury, the contact area between the stent surface and the patient's tendon is narrow, resulting in poor support for the patient's tendon. In addition, during the installation of this sustained-release drug-eluting stent, multiple sets of elastic wires need to be tied together. The process of finding the corresponding elastic wires not only wastes the time of medical staff, but also affects the effectiveness of the sustained-release drug-eluting stent.

Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To solve the above problems, the present invention adopts the following technical solution.

[0007] A sustained-release drug support and release device includes a top cover, a top tube welded to the bottom outer edge of the top cover, a rubber sleeve fitted to the bottom end of the outer wall of the top tube, a bottom tube fitted to the bottom end of the inner wall of the rubber sleeve, a bottom cover welded to the bottom of the bottom tube, a drug placed in the bottom tube, a degradation membrane penetrating the bottom end of the inner wall of the bottom tube, an exhaust pipe vertically penetrating the center of the top of the top cover, a sealing cap threaded to the top of the outer wall of the exhaust pipe, a side band fixedly connected to the outer wall of the top tube, a side plate fixedly connected to one end of the side band, a slot formed at the center of the outer wall of one side of the side plate, an elastic band fixedly connected to the other end of the side band, a sliding frame fixedly connected to the end of the elastic band, a locking block slidably connected to the inner wall of the sliding frame, and the protruding end of the locking block being able to insert into the inner wall of the slot.

[0008] As a further description of the above technical solution:

[0009] The bottom of the top pipe is welded with a first connecting pipe, and a collar is rotatably connected to the outer wall of the first connecting pipe. The bottom of the inner wall of the collar is threadedly connected to a second connecting pipe, and the bottom of the second connecting pipe is welded to the top of the bottom pipe.

[0010] As a further description of the above technical solution:

[0011] The top cover has insertion rods welded to both ends at the bottom, and the bottom cover has connecting rods welded to both ends at the top. The bottom of the outer wall of each insertion rod is inserted into the inner wall at the center of the top of the connecting rod.

[0012] As a further description of the above technical solution:

[0013] Both ends of the bottom cover are fixedly connected to shaft blocks, and a threaded shaft is welded to the center of the bottom of each shaft block. Nuts are threadedly connected to the outer wall of each threaded shaft.

[0014] As a further description of the above technical solution:

[0015] The bottom ends of the shaft block are each welded with a vertical rod, the bottom of the vertical rod is each welded with a hollow tube, the top ends of the top cover are each welded with a plug shaft, and the top of the plug shaft is each welded with a threaded rod.

[0016] As a further description of the above technical solution:

[0017] A baffle is fixedly connected to the center of the inner wall of the slide frame. A limit rod is welded to the same end of the top and bottom of the baffle. A reset spring is sleeved on the outer end of the limit rod near the baffle.

[0018] As a further description of the above technical solution:

[0019] The top and bottom of the inner wall of the sliding frame are vertically penetrated by sleeves, and the inner wall of each sleeve is slidably connected with a pressing rod. The bottom of each pressing rod is welded to the same end opposite to the card block. The card block has a vertically penetrating limiting hole. The end of the outer wall of the limiting rod away from the baffle is sleeved with the inner wall of the limiting hole.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] (1) By setting an exhaust pipe, staff can draw a negative pressure vacuum inside the support release frame, which can release drugs for 6 months. The locking blocks on one set of support release frames can be inserted horizontally into the inner wall of the slot on another set of support release frames. In this way, multiple sets of the same support release frames can be assembled together horizontally, thereby adjusting the size of the support release frame. By assembling multiple sets of support release frames together, the contact area between the surface of the stent and the patient's tendon can be further expanded, thereby achieving a good support effect. By setting a simple connection method between the locking blocks and the slots, the installation steps of the support release frame are more convenient and quick, which not only saves the time of medical staff, but also improves the use effect of the sustained-release drug stent.

[0022] (2) When a medical staff member squeezes the two sets of pressing rods in the sliding groove frame with one hand, the locking block can be disengaged from the slot, and the horizontal support release frame is also removed. When the medical staff member removes the pressing rod, the return spring on the outer wall of the top and bottom limit rods of the baffle will push the locking block back to its original position. By setting the elastic band, it is beneficial to improve the tightness of the enclosure of the patient's tendon injury site by the multiple sets of support release frames. The insert shaft and threaded rod above one set of support release frames can penetrate vertically upward through the hollow tube below the other set of support release frames. At this time, the threaded rod extending out of the hollow tube is located at the two sets of vertical support release frames below the other set of support release frames. Between the rods, unscrew the nuts on the threaded shaft below a set of support release frames, and install the unscrewed nuts on the threaded rod below. After tightening both sets of nuts below a set of support release frames, the two sets of support release frames are longitudinally assembled. In this way, multiple identical sets of support release frames can be longitudinally assembled together, thereby adjusting the height of the entire support release frame. By setting the connecting structure between the first connecting pipe, the collar, and the second connecting pipe, the top pipe and the bottom pipe can be fixed together to form a closed structure. Before the top pipe and the bottom pipe are assembled, the drug can be put into the bottom pipe. Attached Figure Description

Detailed Implementation

[0032] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0033] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0035] Reference Figure 1 , Figure 3 and Figure 4As shown, this is one embodiment of the present invention: a sustained-release drug support release frame, including a top cover 1, a top tube 2 welded to the outer edge of the bottom of the top cover 1, a first connecting tube 3 welded to the bottom of the top tube 2, a collar 4 rotatably connected to the outer wall of the first connecting tube 3, a second connecting tube 5 threaded to the bottom end of the inner wall of the collar 4, and a threaded bottom end of the inner wall of the collar 4; a bottom tube 6 fixedly connected to the bottom of the second connecting tube 5, and a bottom cover 33 welded to the bottom of the bottom tube 6; by setting the connection structure between the first connecting tube 3, the collar 4, and the second connecting tube 5, the top tube 2 and the bottom tube 6 can be fixed together to form a closed structure; insert rods 7 are welded to both ends of the bottom of the top cover 1, and connecting rods 8 are welded to both ends of the top of the bottom cover 33; the bottom ends of the outer walls of the insert rods 7 are inserted into the inner wall of the top center of the connecting rods 8. Next, by setting the connection structure between the insertion rod 7 and the connecting rod 8, the installation position between the top tube 2 and the bottom tube 6 can be limited. The bottom tube 6 contains the drug 9. Before the top tube 2 and the bottom tube 6 are assembled, the drug 9 can be put into the bottom tube 6. The bottom of the outer wall of the top tube 2 and the top of the outer wall of the bottom tube 6 are both fitted with rubber sleeves 10. By setting the rubber sleeves 10, the assembly part of the top tube 2 and the bottom tube 6 can be covered, which not only improves the safety of the connection structure between the first connecting tube 3, the collar 4 and the second connecting tube 5, but also avoids the abrasion of the patient's skin caused by the support frame. The bottom of the inner wall of the bottom tube 6 is penetrated by a degradation film 11. When the degradation film 11 is degraded, the drug 9 in the bottom tube 6 will fall on the tendon injury site, which is conducive to accelerating the repair speed of the tendon injury site.

[0036] Reference Figure 2 , Figure 4 , Figure 5 and Figure 7 As shown, the bottom cover 33 has shaft blocks 12 fixedly connected to both ends of the bottom. Threaded shafts 13 are welded to the center of the bottom of each shaft block 12. Nuts 14 are threadedly connected to the outer wall of each threaded shaft 13. Vertical rods 15 are welded to both ends of the bottom of each shaft block 12. Hollow tubes 16 are welded to the bottom of each vertical rod 15. Inserted shafts 17 are welded to both ends of the top of the top cover 1. Threaded rods 18 are welded to the top of each inserted shaft 17. The inserted shafts 17 and threaded rods 18 above one set of support release frames can vertically pass through the hollow tubes 16 below another set of support release frames. At this time, the threaded rods 18 extending from the hollow tubes 16 are located between the two sets of vertical rods 15 below the other set of support release frames. Then, the nuts 14 on the threaded shafts 13 below one set of support release frames are unscrewed, and the unscrewed nuts 14 are installed on the threaded rods 18 below. After all the nuts 14 below one set of support release frames are tightened, the two sets of support release frames are longitudinally assembled. In this way, multiple identical sets of support release frames can be longitudinally assembled together, thereby adjusting the height of the entire support release frame.

[0037] Reference Figure 4 , Figure 6 and Figure 7As shown, an exhaust pipe 19 is vertically inserted through the center of the top of the top cover 1. A sealing cap 20 is threaded to the top of the outer wall of the exhaust pipe 19. By setting the exhaust pipe 19, the staff can create a negative pressure vacuum inside the support release frame, which can release the drug 9 in the bottom tube 6 for 6 months. A side strip 21 is fixedly connected to the outer wall of the top tube 2. A side plate 22 is fixedly connected to one end of the side strip 21. A slot 23 is opened at the center of the outer wall of one side of the side plate 22. An elastic band 24 is fixedly connected to the other end of the side strip 21. A sliding frame 25 is fixedly connected to the end of the elastic band 24. A baffle 26 is fixedly connected to the center of the inner wall of the sliding frame 25. A limit rod 27 is welded to the same end of the top and bottom of the baffle 26. A return spring 28 is sleeved on the end of the outer wall of the limit rod 27 near the baffle 26. A sleeve 29 is vertically inserted through the top and bottom of the inner wall of the sliding frame 25. A pressing rod 30 is slidably connected to the inner wall of the sleeve 29. Each part is welded with a locking block 31, and the locking block 31 has a vertically penetrating limiting hole 32. The end of the outer wall of the limiting rod 27 away from the baffle 26 is sleeved with the inner wall of the limiting hole 32. The locking block 31 on one set of support release frames can be inserted horizontally into the inner wall of the locking groove 23 on another set of support release frames. In this way, multiple sets of identical support release frames can be assembled together horizontally, thereby adjusting the enclosure size of the support release frames. When the medical staff squeezes the two sets of pressing rods 30 in the slide frame 25 with one hand, the locking block 31 can be disengaged from the locking groove 23, and the horizontal support release frame is also removed. When the medical staff removes the pressing rod 30, the return spring 28 on the outer wall of the limiting rod 27 at the top and bottom of the baffle 26 will push the locking block 31 back to its original position. By setting the elastic band 24, it is beneficial to improve the enclosure tightness of multiple sets of support release frames for the patient's tendon injury site.

[0038] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
