[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Example 1, refer to Figure 1-5 A spray-type drug delivery device includes a tube 2 and a drug delivery tube 1;

[0025] Piston 4 is installed inside the tube 2. Push rod 5 is connected to the top of piston 4. Connecting pipe 3 is connected to one end of tube 2.

[0026] The administration tube 1 is connected to the connecting tube 3 via the flexible tube 6. A baffle 14 is connected to the outer ring of one end of the administration tube 1. A gripping structure is provided on one side of the baffle 14. Several grooves 12 are opened on the outer ring of the administration tube 1. Several liquid outlet holes 15 communicating with the inside of the administration tube 1 are opened on the outside of the administration tube 1.

[0027] This solution includes the following workflow:

[0028] When using this spray-type medication application device, medical personnel first inject the medication into the tubing 2, ensuring that the piston 4 is at the bottom of the tubing 2. Then, the medical personnel connect the medication delivery tube 1 to the connecting pipe 3 at one end of the tubing 2 via the flexible hose 6, ensuring a tight, leak-free connection. During medication application, the medical personnel hold the baffle 14 at one end of the medication delivery tube 1, using the grip structure to stably control the tube 1, and then insert the tube 1 into the patient's body, especially the female genital area, a key medication application area. By evenly pushing the push rod 5, the piston 4 moves upward within the tubing 2, generating pressure to push the medication through the flexible hose 6 into the medication delivery tube 1. The medication is then evenly sprayed into the patient's body through the outlet hole 15 on the outside of the medication delivery tube 1, achieving medication application. Medical personnel can control the pushing speed of the push rod 5 and the insertion depth of the medication delivery tube 1 as needed to achieve the desired medication application effect.

[0029] Based on the above work process, it can be concluded that:

[0030] This spray-type medication application device effectively addresses many shortcomings of existing technologies. Firstly, the outlet 15 on the outside of the medication tube 1 ensures uniform medication application, significantly improving the uniformity of medication delivery and thus enhancing treatment efficacy and patient comfort. Secondly, medical staff can focus more on controlling the insertion depth of the medication tube 1 and the pushing speed of the push rod 5, without needing to perform multiple steps simultaneously, greatly improving the efficiency of medication application and reducing the workload of medical staff. Furthermore, the device's simple structure and convenient operation better meet the treatment needs of modern obstetrics and gynecology, providing medical staff with a more efficient and precise medication application tool, further promoting the continuous development of obstetrics and gynecology medical technology.

[0031] Example 2, refer to Figure 1-5 Both sides of the tube 2 are equipped with push handles at the top. The push handles are fixedly connected to the side wall of the tube 2. By fixing the push handles to the side wall of the tube 2, medical staff can more easily hold and push the tube 2 during use. Especially when a larger pushing force is required, the push handles provide additional points of force and support, making the operation more stable and achieving the effect of improving the convenience of operation and the efficiency of drug administration.

[0032] A push plate is fixedly connected to the top of the push rod 5. Several anti-slip grooves are provided on the top of the push plate. With the push plate fixedly connected to the top of the push rod 5 and several anti-slip grooves on the top of the push plate, medical staff can hold the push plate more firmly during the medication application process. The anti-slip grooves effectively prevent the hand from slipping, increase the stability and control precision of the operation, and achieve the effect of improving the uniformity of medication application and the therapeutic effect.

[0033] The outer ring of the connecting tube 3 has an external thread, and the end of the hose 6 near the connecting tube 3 is connected to a connecting tube 7 that is compatible with the connecting tube 3. The inner ring of the connecting tube 7 has an internal thread 8. By having an external thread on the outer ring of the connecting tube 3 and a connecting tube 7 that is compatible with the connecting tube 3 at the end of the hose 6 near the connecting tube 3, and an internal thread 8 on the inner ring of the connecting tube 7, a quick and tight connection between the drug delivery tube 1 and the tube 2 is achieved, ensuring the sealing and leak-free nature of the drug solution during transmission, thereby improving the reliability of the device and the safety of drug delivery.

[0034] The outer ring of the connecting pipe 7 is fixedly connected with several protruding strips 9. The protruding strips 9 are made of rubber. The setting of the protruding strips 9 being made of rubber increases the friction between the connecting pipe 7 and the connecting pipe 3, making the connection more stable. At the same time, the rubber protruding strips 9 also play a buffering role, reducing the impact force during connection, thereby improving the durability of the device and the comfort of operation.

[0035] A delivery tube 13, which communicates with the end of the administration tube 1, is provided on one side of the baffle 14. The grip structure includes two symmetrically arranged contact plates 10, which are respectively located on both sides of the delivery tube 13. The contact plates 10 are arc-shaped, and one end of the contact plate 10 is connected to one side of the delivery tube 13 through a connecting plate 11. The baffle 14 provides a connection between the delivery tube 13 and the end of the administration tube 1. The grip structure includes two symmetrically arranged contact plates 10, which are respectively located on both sides of the delivery tube 13. The contact plates 10 are arc-shaped, and one end of the contact plate 10 is connected to one side of the delivery tube 13 through a connecting plate 11. This design allows medical personnel to grip the administration tube 1 more comfortably and stably. The arc-shaped contact plates 10 adapt to the natural shape of the hand, providing a better grip experience. At the same time, the design of the delivery tube 13 ensures the smooth transmission of the medication, thereby improving the ease of operation and the comfort of medication administration.

[0036] In summary: When using this spray-type medication delivery device, medical personnel first inject the medication into the tube 2, ensuring that the piston 4 is at the bottom of the tube 2. Then, the medical personnel connect the medication delivery tube 1 to the connecting pipe 3 at one end of the tube 2 via the flexible tube 6. Specifically, this is achieved by tightening the connecting pipe 7 at one end of the flexible tube 6 to the connecting pipe 3, achieving a quick and tight connection. The fit between the external and internal threads 8 ensures a tight seal and no leakage during medication delivery. Simultaneously, the protrusion 9 on the connecting pipe 7 increases friction, making the connection more stable, and the rubber protrusion 9 acts as a buffer, reducing the impact force during connection. During medication delivery, the medical personnel hold the baffle 14 at one end of the medication delivery tube 1, using the grip structure to stably control the tube 1. The grip structure includes two symmetrically arranged contact plates 10; the arc-shaped design of the contact plates 10 adapts to the natural shape of the hand, providing a better grip experience. Meanwhile, the design of the delivery tube 13 ensures smooth medication delivery. Subsequently, the medical personnel insert the medication delivery tube 1 into the patient's body, especially into the core medication delivery area of ​​the female genitalia. By uniformly pushing the push rod 5, the piston 4 moves upward within the tube 2, generating pressure to push the medication through the hose 6 into the administration tube 1. The medication is then evenly sprayed into the patient's body through the outlet hole 15 on the outside of the administration tube 1, achieving medication administration. During this process, the push plate at the top of the push rod 5 and its anti-slip groove provide a non-slip function, allowing medical personnel to hold the push rod 5 more firmly, increasing the stability and control precision of the operation. The push handles on both sides of the tube 2 provide additional points of leverage and support for medical personnel, making the operation more stable, especially when greater pushing force is required. Medical personnel can control the pushing speed of the push rod 5 and the insertion depth of the administration tube 1 as needed to achieve the ideal medication administration effect.

[0037] This spray-type medication application device effectively addresses many shortcomings of existing technologies. Firstly, the outlet 15 on the outside of the medication tube 1 ensures uniform medication application, significantly improving the uniformity of medication delivery and thus enhancing treatment efficacy and patient comfort. Secondly, medical staff can focus more on controlling the insertion depth of the medication tube 1 and the pushing speed of the push rod 5, without needing to perform multiple steps simultaneously, greatly improving the efficiency of medication application and reducing the workload of medical staff. Furthermore, the device has a simple structure and is easy to operate, better meeting the treatment needs of modern obstetrics and gynecology, and providing medical staff with a more efficient and precise medication application tool. Specifically, by fixing the pusher to the side wall of the tube 2, medical staff can more easily grip and push the tube 2 during use, making the operation more stable and improving the convenience of operation and the efficiency of drug delivery. By fixing the push plate to the top of the push rod 5, with several anti-slip grooves on the top of the push plate, medical staff can grip the push plate more firmly during drug delivery, increasing the stability and control precision of the operation, thus improving the uniformity of drug delivery and the therapeutic effect. By having an external thread on the outer ring of the connecting tube 3, and a matching connecting tube 7 connected to the end of the hose 6 near the connecting tube 3, with an internal thread 8 on the inner ring of the connecting tube 7, a quick and tight connection between the drug delivery tube 1 and the tube 2 is achieved, ensuring the sealing and leak-free nature of the drug solution during transmission, thus improving the reliability of the device and the safety of drug delivery. Several protruding strips 9 are fixedly connected to the outer ring of the connecting tube 7. These protruding strips 9 are made of rubber, increasing the friction between the connecting tube 7 and the connecting tube 3, making the connection more stable. Simultaneously, the rubber protruding strips 9 also act as a buffer, reducing the impact force during connection, thus improving the durability and operational comfort of the device. A delivery tube 13, connected to the end of the medication tube 1, is located on one side of the baffle 14. The grip structure includes two symmetrically arranged contact plates 10, respectively positioned on both sides of the delivery tube 13. The contact plates 10 are arc-shaped, and one end of each contact plate 10 is connected to one side of the delivery tube 13 via a connecting plate 11. This design allows medical personnel to grip the medication tube 1 more comfortably and stably, providing a better grip experience. Furthermore, the design of the delivery tube 13 ensures smooth drug delivery, improving operational convenience and medication administration comfort. In summary, the design of this jet-type medication administration device further promotes the continuous development of obstetrics and gynecology medical technology.
