Description

Technical Field

[0001] This utility model relates to the field of medical consumables, and in particular to a drug delivery device. Background Technology

[0002] Currently, it is common in clinical treatment to administer medication, disinfect, or treat the human reproductive or excretory tract. For example, during cervical treatment in women, it is necessary to disinfect and administer medication to the cervix. Since the medication site is located inside the body, medication delivery devices have been developed to complement it. Existing medication delivery devices mainly include a squeezing capsule for storing the medication and a catheter for delivering the medication. Existing devices have problems such as unstable squeezing capsule structure, difficulty in squeezing the medication, and a single dispensing method from the catheter, which makes it impossible to deliver medication to all parts of the medication site. Utility Model Content

[0003] To overcome the above problems, this utility model provides a drug delivery device. The technical solution adopted by this utility model to solve its technical problems is as follows:

[0004] A drug delivery device includes a hollow drug reservoir, the sidewall of which includes several parallel drug reservoir ribs connected to each other by drug reservoir springs. The drug reservoir has a drug delivery port, which is detachably fixed to one end of a drug delivery tube. The other end of the drug delivery tube is connected to a drug delivery head, which has several drug delivery holes and several brush heads.

[0005] Furthermore, raised reinforcing bases are evenly distributed around the drug delivery head, and the brush heads are evenly arranged on the reinforcing bases.

[0006] Furthermore, the drug delivery holes are evenly distributed between the bases.

[0007] Furthermore, the tip of the drug delivery head is also provided with a drug delivery hole, and the diameter of the drug delivery hole at the tip of the drug delivery head is larger than that of the drug delivery hole between the reinforcing bases.

[0008] Furthermore, the administration tube is detachably and fixedly connected to the administration head, and both the administration head and the administration tube are integrally molded.

[0009] Furthermore, a connecting seat is provided at one end of the drug delivery tube that connects to the drug delivery port, and reinforcing ribs are provided on the inner wall of the connecting seat.

[0010] Furthermore, a sealing ring is provided between the administration tube and the administration port.

[0011] Furthermore, the administration tube and the administration port are connected by threads or an interference fit.

[0012] The beneficial effects of this utility model are:

[0013] The drug delivery device includes a hollow drug reservoir. The side wall of the drug reservoir includes several parallel drug reservoir ribs, which are connected by drug reservoir springs. The drug reservoir has a drug delivery port, which is detachably fixed to one end of a drug delivery tube. The other end of the drug delivery tube is connected to a drug delivery head, which is provided with several drug delivery holes and several brush heads. The drug reservoir of this device maintains structural stability through the drug reservoir ribs and works with the drug reservoir springs to achieve stable extrusion of the drug.

[0020] To better understand the purpose, structure, and function of this utility model, the following detailed description of a specific embodiment of "a drug delivery device" of this utility model is provided in conjunction with the accompanying drawings.

[0021] See Figure 1In this embodiment, the drug delivery device includes a hollow drug reservoir 100. The sidewall of the drug reservoir 100 includes several parallel drug reservoir ribs 101, which are connected to each other by drug reservoir springs 102. The drug reservoir 100 has a drug delivery port 103, which is detachably fixed to one end of a drug delivery tube 200. The other end of the drug delivery tube 200 is connected to a drug delivery head 201, which has several drug delivery holes 202 and several brush heads 203. When medication is needed, the operator holds the drug reservoir 100, moves the drug delivery head 201 to the desired location, and then presses the bottom of the drug reservoir 100. The drug reservoir springs 102 are compressed, and the medication is secreted through the drug delivery tube 200 and from the drug delivery holes 202 of the drug delivery head 201. At the same time, the operator moves the drug delivery device back and forth and rotates it, applying the secreted medication to the application site using the brush heads 203 on the drug delivery head 201. This method is convenient to use.

[0022] It should be noted that this device uses the drug storage bladder rib 101 for support, and works in conjunction with the elastic drug storage bladder spring 102 to achieve stable drug dispensing. The brush head on the dispensing head 201 evenly applies the medication to the application site, achieving medication application without dead angles. Furthermore, this device can not only be used for medication application, but also for cleaning and disinfecting the application site. Disinfectant or cleaning solution is secreted through the dispensing hole 202, and the brush head 203 assists in scrubbing the application site, achieving better cleaning and disinfection effects.

[0023] See further Figure 2 In this embodiment, preferably, raised reinforcing bases 204 are uniformly provided around the drug delivery head 201, and brush heads 203 are uniformly arranged on the reinforcing bases 204 to improve the connection between the brush heads 203 and the drug delivery head 201, so as to prevent the brush heads 203 from falling off and remaining at the drug application site during use.

[0024] More specifically, in this embodiment, the drug administration holes 202 on the side wall of the drug administration head 201 are evenly arranged between the reinforcing bases 204. This not only allows the drug administration holes 202 to secrete the drug evenly, but also, since the reinforcing bases 204 are raised and the drug administration holes 202 are located in the recessed grooves, the reinforcing bases 204 can guide the drug administration, prevent the drug from escaping to other locations, and improve the drug utilization rate.

[0025] Furthermore, in this embodiment, the top of the drug delivery head 201 is also provided with a drug delivery hole 202, and the diameter of the drug delivery hole 202 at the top of the drug delivery head 201 is larger than that of the drug delivery hole 202 between the reinforcing bases 204. This is because the delivery position at the top is more controllable, making it easier to deliver the drug to the required drug delivery position. At the same time, the drug delivery hole 202 at the top, together with the drug delivery hole 202 on the side wall, can improve the drug delivery efficiency.

[0026] Furthermore, in this embodiment, the drug delivery tube 200 and the drug delivery head 201 are detachably fixedly connected, preferably with an interference fit; both the drug delivery head 201 and the drug delivery tube 200 are integrally molded. The detachable connection allows the drug delivery tube 200 and the drug delivery head 201 to be molded separately, reducing the difficulty of integral molding. At the same time, the integrally molded drug delivery tube 200 and drug delivery head 201 can have better strength and quality.

[0027] See further Figure 1 and Figure 2 In this embodiment, a connecting seat 205 is provided at one end of the drug delivery tube 200 that is connected to the drug delivery port 103. The inner wall of the connecting seat 205 is provided with reinforcing ribs to strengthen the connection between the drug delivery tube 200 and the drug delivery port 103 and prevent breakage during use.

[0028] More specifically, in this embodiment, the administration tube 200 and the administration port 103 are connected by a thread or an interference fit, and a sealing ring is provided between the administration tube 200 and the administration port 103 to ensure the sealing of the connection.
