Description

Technical Field

[0001] This utility model belongs to the field of syringe technology, specifically relating to an integrated pre-filled syringe. Background Technology

[0002] The main body of the syringe is made of transparent medical-grade COC material. The transparent syringe makes the solution inside easier to observe. This design not only facilitates intuitive inspection of the drug's condition but also ensures the product's hygiene and durability. The position of the piston can be clearly observed through the transparent body, facilitating precise control of the dosage. At the same time, the COC material makes the syringe lightweight, compact, and portable.

[0003] In the medical field, syringe needles are widely used in various procedures such as drug administration, blood drawing, and vaccination. However, existing syringe needles generally lack effective protective structures, which significantly increases the risk of needle pricks during use and handling. This risk not only harms medical staff but may also pose a potential threat of infection and disease transmission to patients. Utility Model Content

[0004] The purpose of this invention is to provide an integrated pre-filled syringe to solve the problem mentioned in the background art that existing syringe needles do not have a protective structure.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An integrated pre-filled syringe, comprising:

[0007] Safety helmet;

[0008] A rubber needle cap is inserted inside a safety cap.

[0009] A sleeve, which is fitted over the rubber needle cap;

[0010] A push rod is inserted inside the sleeve. The bottom end of the push rod is fixedly connected to a push seat. The push seat has push rod wing plates on both sides.

[0011] Preferably, the outer surface of the push base is provided with base anti-slip texture, and the outer surface of the two wing plates of the push rod is provided with push rod anti-slip texture.

[0012] Preferably, the sleeve has a wavy anti-slip texture in the middle, and the push rod has recessed finger supports on the outside of the two wing plates to facilitate thumb and index finger positioning.

[0013] Preferably, the push rod is slidably connected inside the sleeve, and the rubber needle cap is engaged and inserted outside the sleeve.

[0014] Preferably, the anti-slip texture on the two wing plates of the push rod can increase the friction when pressing.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features a push rod, push seat, push rod wings, and anti-slip texture on the base, resulting in a syringe with smooth lines and a simple yet technologically advanced design. The main body is cylindrical, with a spacious drug reservoir at one end for pre-filling with the appropriate amount of medication, and the other end gradually narrowing to a fine needle tip. When not in use, the needle tip is securely covered by a detachable rubber needle cap and a safety protection device, preventing contamination and protecting the user from accidental injury. Furthermore, the addition of wavy anti-slip texture in the middle of the sleeve enhances grip friction, improving applicability in various scenarios, making the syringe suitable for wet conditions or when wearing gloves, and reducing the risk of slippage.

[0021] 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.

[0022] Example 1:

[0023] Please see Figures 1-3 As shown, an integrated pre-filled syringe includes:

[0024] Safety helmet 1;

[0025] Rubber needle cap 2, which is inserted inside the safety cap 1;

[0026] Sleeve 3, which is sleeved on the outside of rubber needle cap 2;

[0027] A push rod 4 is inserted inside the sleeve 3. A push seat 5 is fixedly connected to the bottom end of the push rod 4. Push rod wing plates 6 are provided on both sides of the push seat 5. The outer side of the push seat 5 is provided with base anti-slip texture 7. The outer side of the push rod wing plates 6 is provided with push rod anti-slip texture 8. The middle part of the sleeve 3 is provided with a wave-shaped anti-slip texture. The outer side of the push rod wing plates 6 is provided with a recessed finger support for easy positioning of the thumb and index finger. The push rod 4 is slidably connected inside the sleeve 3. The rubber needle cap 2 is snapped into the outer side of the sleeve 3. The push rod anti-slip texture 8 on the push rod wing plates 6 can increase the friction when pressing.

[0028] Specifically, the sleeve 3 has a recessed finger rest at the tail, which facilitates the positioning of the thumb and index finger and improves operational stability. When not in use, the needle tip is safely covered by a removable rubber needle cap 2 and covered with a safety protection device, which not only prevents contamination but also protects the user from accidental injury.

[0029] As can be seen from the above, when using the device, first pull down the safety cap 1 towards the rolled edge to expose the rubber needle cap 2, then pull out the rubber needle cap 2 to complete the injection operation. At this time, push back the safety cap 1 to activate the locking between the safety cap 1 and the needle, which plays a protective role. Finally, throw the protected needle into the sharps container.
