Description

Technical Field

[0001] This utility model relates to the field of drug delivery device technology, specifically a stem cell injection drug delivery device. Background Technology

[0002] With the rapid development of society and the economy, many men's health is compromised due to factors such as overnutrition, reduced physical labor, sedentary lifestyles, and increased work pressure. Erectile dysfunction (ED) is often the first sign of health problems in men. Depression, anxiety, strained interpersonal relationships, smoking, excessive drinking, overwork, and immense stress can all lead to ED in men.

[0003] Currently, treatments for erectile dysfunction mainly include oral medications, vacuum pumps, vascular surgery, penile prostheses, and intracavernosal injections. Oral medications have limited efficacy, and vacuum pumps may be difficult to use for some men, and improper use can lead to penile damage. The success rate of vascular surgery is 31-80%. Penile prosthesis implantation is a creative, expensive, and irreversible surgical procedure that can lead to penile deformities. Intracavernosal injection of vasoactive drugs is satisfactory or effective for 30-90% of patients, but it may be accompanied by pain, priapism, penile hematoma, and fibrosis.

[0004] The current need is to administer stem cell injections for the treatment of erectile dysfunction. However, existing syringes, designed to minimize trauma to the male corpora cavernosa, generally have long and thin needles, which reduces needle rigidity. Existing stem cell injection devices do not provide adequate protection for the needles, often using plastic protective sleeves on the needle's outer surface. This fails to adequately protect the needles, making them prone to bending and breakage, thus affecting usability. Therefore, a stem cell injection device is proposed. Utility Model Content

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5 This utility model provides a new technical solution: a stem cell injection drug delivery device, including a syringe 1, an observation window 2 fixedly installed on the outer surface of the syringe 1, and a needle 7 movably installed on the right surface of the syringe 1;

[0029] The syringe 1 is equipped with a protective mechanism, which includes a hollow column 3, a protective sleeve 4, a sealing groove 5, a locking hole 6, a push rod 8, a push handle 9, a piston head 10, a rubber sealing ring 11, a sealing gasket 12, a sliding groove 13, two springs 14, two fixing plates 15, a ring 16, two round holes 17, and two round beads 18.

[0030] Among them, the push rod 8 is slidably sleeved on the inner surface of the syringe 1, the push handle 9 is fixedly installed on the left end of the push rod 8, and the piston head 10 is fixedly installed on the right end of the push rod 8.

[0031] The sealing groove 5 is formed on the outer surface of the syringe 1, and the two locking holes 6 are formed on the outer surface of the syringe 1.

[0032] The protective sleeve 4 is disposed on the outer surface of the syringe 1, and the sealing gasket 12 is fixedly installed in the inner wall of the protective sleeve 4.

[0033] The hollow column 3 is fixedly installed on the left surface of the protective sleeve 4, and the rubber sealing ring 11 is fixedly installed in the inner wall of the hollow column 3.

[0034] Furthermore, the groove 13 is formed on the outer surface of the hollow column 3, two round holes 17 are formed on the inner surface of the groove 13, and two round beads 18 are disposed on the inner surface of the two round holes 17.

[0035] Furthermore, two springs 14 are fixedly installed in the inner wall of the slide groove 13, and two fixing plates 15 are fixedly installed at the right end of the two springs 14. The opposing surfaces of the two fixing plates 15 are both set at an angle.

[0036] Among them, the ring 16 is fixedly installed on the outer surface of the two fixed plates 15, and the ring 16 is slidably sleeved on the inner surface of the groove 13.

[0037] When using this stem cell injection device, a leftward pushing force is applied to the ring 16, causing it to move to the left. Simultaneously, the ring 16 moves the two fixed plates 15, which are fixedly mounted on its inner surface, to the left. At this time, the two fixed plates 15 exert pressure on the two springs 14 fixedly mounted on the left surface, causing them to contract. The two fixed plates 15 no longer obstruct the two circular holes 17, i.e., they no longer limit the two beads 18 set inside the two circular holes 17. Then, by inserting the syringe 1 into the inner surface of the hollow column 3 and aligning the two locking holes 6 on the outer surface of the syringe 1 with the two circular holes 17, the leftward pushing force is no longer applied to the ring 16, and the two springs 14 are no longer under force. The two springs 14 expand, applying a rightward pushing force to the two fixed plates 15 fixedly mounted on the right end, causing them to slide to the right within the inner wall of the slide groove 13. At this time, the inclined surfaces of the two fixed plates 15 impact the two... Two round beads 18 are pushed against each other, causing them to move towards each other and engage with the two locking holes 6 on the outer surface of the syringe 1 for fixation. At the same time, the needle 7 is inserted into the sealing gasket 12 fixedly installed in the inner wall of the protective sleeve 4 for sealing to prevent the carrying of bacteria. After installation, the rubber sealing ring 11 fixedly installed on the inner surface of the hollow column 3 fills the sealing groove 5 on the outer surface of the syringe 1 for sealing treatment to prevent bacteria from entering the protective sleeve 4 and contaminating the needle 7. When injecting, a downward pushing force is applied to the push handle 9, which in turn applies a downward pushing force to the push rod 8 fixedly installed on the lower surface. The push rod 8 drives the piston head 10 fixedly installed at the lower end to move downward on the inner surface of the syringe 1, injecting stem cells for treating erectile dysfunction through the needle 7. The injection volume can be observed through the observation window 2 fixedly installed on the outer surface of the syringe 1 and the scale on the outer surface of the push rod 8.

[0038] This stem cell injection device uses a snap-fit ​​mechanism to install a rigid protective sleeve 4 to protect the fine needle 7, preventing it from bending due to external factors. After installation, a rubber sealing ring 11 fixedly installed on the inner surface of the hollow column 3 fills the sealing groove 5 on the outer surface of the syringe 1 for sealing, preventing bacteria from entering the protective sleeve 4 and contaminating the needle 7. Simultaneously, the needle 7 is inserted into a sealing gasket 12 fixedly installed in the inner wall of the protective sleeve 4 for sealing, preventing the carrying of bacteria and improving the protection of the needle 7. During injection, the dosage can be observed through the observation window 2 fixedly installed on the outer surface of the syringe 1 and the scale on the outer surface of the push rod 8, allowing patients to perform quantitative injections according to their individual needs.

[0039] Working Principle: When this stem cell injection device is in use, a leftward pushing force is applied to the ring 16, causing it to move to the left. Simultaneously, the ring 16 drives the two fixed plates 15, which are fixedly mounted on its inner surface, to move to the left. At this time, the two fixed plates 15 apply pressure to the two springs 14 fixedly mounted on the left surface, causing them to contract. The two fixed plates 15 no longer obstruct the two circular holes 17, i.e., they no longer limit the two beads 18 set inside the two circular holes 17. Then, by inserting the syringe 1 into the inner surface of the hollow column 3 and aligning the two locking holes 6 on the outer surface of the syringe 1 with the two circular holes 17, the leftward pushing force is no longer applied to the ring 16, and the two springs 14 are no longer under force. The two springs 14 expand, applying a rightward pushing force to the two fixed plates 15 fixedly mounted on the right end, causing them to slide to the right within the inner wall of the slide groove 13. At this time, the inclined surfaces of the two fixed plates 15 impact... Two round beads 18 are applied to each other with a force on their opposing surfaces, causing them to move towards each other and engage with the two locking holes 6 on the outer surface of the syringe 1 for fixation. At the same time, the needle 7 is inserted into the sealing gasket 12 fixedly installed in the inner wall of the protective sleeve 4 for sealing to prevent the introduction of pathogens. After installation, the rubber sealing ring 11 fixedly installed on the inner surface of the hollow column 3 fills the sealing groove 5 on the outer surface of the syringe 1 for sealing treatment to prevent pathogens from entering the protective sleeve 4 and contaminating the needle 7. During injection, a downward force is applied to the push handle 9, which in turn applies a downward force to the push rod 8 fixedly installed on the lower surface. The push rod 8 drives the piston head 10 fixedly installed at the lower end to move downward on the inner surface of the syringe 1, injecting stem cells for the treatment of erectile dysfunction through the needle 7. The injection volume can be observed through the observation window 2 fixedly installed on the outer surface of the syringe 1 and the scale on the outer surface of the push rod 8.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
