Description

Technical Field

[0001] The utility model relates to the field of anorectal drug delivery devices, in particular to a drug delivery device for clinical anorectal surgery. Background Art

[0002] The anorectal applicator is a conical hollow drug delivery device. In the prior art, the applicator is generally directly threadedly connected to the connector of the ointment outer packaging, and then the applicator is inserted into the anus, and the ointment outer packaging is squeezed to squeeze the ointment into the anus through the applicator.

[0003] In the above method, since the applicator is in direct contact with the anal environment, it should be discarded after one use. This method also discards the ointment remaining in the applicator, which not only increases the cost of the applicator but also causes a problem of high drug costs. Utility Model Content

[0004] The purpose of the present utility model is to provide a drug delivery device for clinical use in anorectal surgery in order to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: a drug dispenser for clinical use in anorectal surgery, comprising a drug dispenser, wherein a docking groove is provided on the top disk of the drug dispenser, an outer protective layer that fits the drug dispenser is sleeved on the outer conical surface of the drug dispenser, and a docking plate that fits the docking groove is fixedly connected to the outer periphery of the top disk of the outer protective layer;

[0006] The bottom end of the drug dispenser is provided with a drug delivery port, and the bottom end of the outer protective layer is formed with an inner retaining ring bent upward, and the outer periphery of the inner retaining ring is in contact with the inner periphery of the drug delivery port.

[0007] As a further solution of the present invention, the inner periphery of the inner retaining ring and the outer periphery of the bottom of the outer protective layer are combined into a continuous arc surface, which is used to reduce the resistance when the ointment is squeezed out.

[0008] As a further solution of the present invention: an internal thread is provided on the inner periphery of the top opening of the applicator, the internal thread is connected to the connector of the ointment outer packaging, and an external thread is formed on the outer periphery of the connector of the ointment outer packaging to engage with the internal thread.

[0009] As a further solution of the present invention: when the dispenser is not in use, a blocking cover is inserted into the bottom end of the dispenser, and a connecting handle is integrally formed at the bottom end of the blocking cover.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] 1. By setting an outer protective layer and an inner retaining ring, the applicator is prevented from contacting the anal environment. After use, only the outer protective layer needs to be replaced without replacing the applicator. In combination with the sealing cap, the drug in the applicator can be utilized, avoiding direct disposal and reducing the cost of using the applicator and the drug.

[0016] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] See also Figures 1 to 3 In an embodiment of the utility model, a drug delivery device for clinical use in anorectal surgery includes a drug delivery device 1, a docking groove 2 is provided on the top disk body of the drug delivery device 1, an outer protective layer 4 that fits the drug delivery device 1 is sleeved on the outer conical surface of the drug delivery device 1, and a docking plate 5 that matches the docking groove 2 is fixedly connected to the outer periphery of the top disk body of the outer protective layer 4; a drug delivery port 6 is provided at the bottom end of the drug delivery device 1, and an inner retaining ring 7 that is bent upward is formed at the bottom end of the outer protective layer 4, and the outer periphery of the inner retaining ring 7 fits with the inner periphery of the drug delivery port 6.

[0018] In this embodiment: first, when using the device to administer anorectal medication, connect the applicator 1 to the connector of the ointment outer package, then press the ointment outer package to squeeze the ointment in the ointment outer package into the applicator 1, and exhaust the air in the inner cavity of the applicator 1, then sleeve the outer protective layer 4 on the outer wall of the applicator 1, and align the docking plate 5 with the docking groove 2 in the upper and lower positions until the outer protective layer 4 is completely sleeved on the outer wall of the applicator 1. At this time, the docking plate 5 passes through the docking groove 2 and moves to the top of the applicator 1, and then rotates The outer protective layer 4 or the docking plate 5 makes the docking plate 5 misaligned with the docking groove 2, and then the applicator 1 is inserted into the patient's anus. During the insertion process, the outer protective layer 4 contacts the skin inside the patient's anus, avoiding direct contact between the applicator 1 and the patient's anus. At the same time, during the pushing process, the mucus or residual excrement or blood in the anus will be stained on the inner retaining ring 7, avoiding direct contact with the applicator 1. Therefore, the outer protective layer 4 and the inner retaining ring 7 can effectively ensure that the applicator 1 does not come into direct contact with the patient's anal environment.

[0019] Please refer to Figure 2 The inner periphery of the inner retaining ring 7 and the outer periphery of the bottom of the outer protective layer 4 are combined into a continuous arc surface, which is used to reduce the resistance when the ointment is squeezed out.

[0020] In this embodiment, the outer continuous arc surface can effectively cause irritation and squeezing to the patient's anus during the pushing process, thereby reducing damage, and when the ointment is squeezed into the patient's anus, there is less resistance, which facilitates the smooth squeezing of the ointment.

[0021] Please refer to Figure 1 、 Figure 2 and Figure 3 The top opening of the applicator 1 is provided with an internal thread 3 on the inner periphery, and the internal thread 3 is connected to the connector of the outer packaging of the ointment. The outer periphery of the connector of the outer packaging of the ointment is formed with an external thread that engages with the internal thread 3.

[0022] In this embodiment, the connector of the outer packaging of the ointment is aligned with the internal thread 3, and then the applicator 1 is rotated to connect the applicator 1 to the outer packaging of the ointment.

[0023] Please refer to Figure 3 When the drug dispensing device 1 is not in use, a blocking cover 8 is inserted into the drug dispensing port 6 at the bottom end of the drug dispensing device 1, and a connecting handle 9 is integrally formed at the bottom end of the blocking cover 8.

[0024] In this embodiment: after the medication is completed, the applicator 1 is pulled out from the patient's anus, the outer protective layer 4 that is in contact with the patient's anal environment is rotated and removed and discarded, and then the connecting handle 9 is held by hand and the rubber sealing cover 8 is pushed into the medication port 6 to avoid the ointment remaining in the applicator 1 from directly contacting the air for a long time, which is convenient for secondary use and reduces loss.

[0025] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
