Description

Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a special infusion bag for drug dripping. Background Technology

[0002] For special medications such as chemotherapy drugs, drugs with incompatible combinations, drugs that easily crystallize or become viscous, anticoagulants or hemostatic agents, traditional Chinese medicine injections, and special antibiotics, intravenous infusion requires flushing the tubing with 0.9% sodium chloride injection or 5% glucose injection before and after administration. Currently, in clinical practice, small packets of 0.9% sodium chloride injection or 5% glucose injection are used before and after administration, requiring repeated insertion and removal of the infusion tubing and verification of the use of special medications. This process is prone to contamination, carries the risk of drug (chemotherapy drugs) leakage, and can easily cause environmental pollution or exposure of medical personnel. The procedure is inconvenient, and the use of flushing solutions before and after administration adds an additional financial burden. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a special infusion bag for drug dripping, so as to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0005] A special infusion bag for drug dripping is provided, comprising a bag body, wherein an upper chamber, a middle chamber, and a lower chamber are sequentially connected from top to bottom within the bag body. A first valve is provided between the upper chamber and the middle chamber, and a second valve is provided between the middle chamber and the lower chamber. Both the first valve and the second valve have manual switches to prevent accidental opening. A drug addition port is provided on one side of the middle chamber, and a leather strap connection port is provided at the lower end of the lower chamber.

[0006] As described in the special infusion bag for dripping special drugs, the first valve is a three-way structure including an upper port, a lower port and a side port. The upper port is connected to the upper chamber, the lower port is connected to the middle chamber, and the manual switch to prevent accidental opening is provided on the side port. The second valve has the same structure as the first valve.

[0007] As described in the special infusion bag for dripping special drugs, the manual switch for preventing accidental opening includes a rotating interface, a connecting rod, and a flip plate connected in sequence. The flip plate is located between the upper port and the lower port and is initially arranged horizontally. The rotating interface is screwed onto the side port, and a tight ring is fitted on the outside of the side port. The rotating interface is point-connected to the tight ring.

[0008] As described in the special infusion bag for drug dripping, the inner bottom surfaces of the upper chamber, the middle chamber, and the lower chamber are all inclined planes with an inclination angle ranging from 10° to 30°.

[0009] As described in the special infusion bag for drug dripping, the volume of the lower chamber is the same as the volume of the upper chamber.

[0010] The beneficial effects of this utility model's technical solution are:

[0011] - Improve operational convenience: Reduce the number of times nursing staff need to scan codes for verification, and reduce the need to repeatedly insert and remove IV tubing for fluid replacement;

[0012] - Improved patient comfort: No need for extra attention to the start and end of infusion, reducing the waiting period for flushing;

[0013] - Improve safety: Avoid exposure risks to specific drugs and reduce drug reactions caused by improper flushing;

[0014] - Improve economic efficiency: Reduce the use of additional solvents and alleviate the economic burden;

[0015] - Reduce infection rate: Eliminate the need for multiple sterilizations of the bottle opening, avoid exposing the bottle opening, and reduce the risk of infection;

Furthermore, terms such as "first," "second," "third," etc., are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0024] See Figure 1 As shown, this utility model of a special infusion bag for drug dripping includes a bag body 1. Inside the bag body 1, from top to bottom, are an upper chamber 2, a middle chamber 3, and a lower chamber 4 connected sequentially. A first valve 5 is provided between the upper chamber 2 and the middle chamber 3, and a second valve 6 is provided between the middle chamber 3 and the lower chamber 4. Both the first valve 5 and the second valve 6 have manual switches to prevent accidental opening. A drug inlet 7 is provided on one side of the middle chamber 3, and a leather strap connection port 8 is provided at the lower end of the lower chamber 4. Both the drug inlet 7 and the leather strap connection port 8 are sterile before use. The three chambers are arranged vertically, allowing the medication to flow naturally under gravity.

[0025] See Figure 2 As shown, the first valve 5 is a three-way structure including an upper port 9, a lower port 10, and a side port 11. The upper port 9 is connected to the upper chamber 2, the lower port 10 is connected to the middle chamber 3, and a manual switch to prevent accidental opening is located on the side port 11. The second valve 6 has the same structure as the first valve 5.

[0026] Furthermore, the anti-accidental opening manual switch includes a rotating connector 12, a connecting rod 13, and a flip plate 14 connected in sequence. The flip plate 14 is located between the upper port 9 and the lower port 10 and is initially arranged horizontally. The rotating connector 12 is screwed onto the side port 11, and a clamping ring 15 is fitted on the outside of the side port 11. The rotating connector 12 is point-connected to the clamping ring 15. It can be understood that, similar to the locking structure of a beverage bottle cap in existing technology, point connections are achieved using materials such as plastic. When manually opening, the rotating connector 12 is twisted until the point connection between the rotating connector 12 and the clamping ring 15 breaks. The rotating connector is then rotated until the flip plate 14 inside flips from horizontal to vertical, connecting the upper and lower ports. This design effectively prevents accidental opening and allows medical personnel to easily determine that each chamber of the infusion bag is in a non-connected state. Before use, the three chambers are independent and completely isolated. The three-way valve controls the unidirectional flow of the medication, ensuring that the medication flows from top to bottom, avoiding backflow caused by bag placement issues, and ensuring effective flushing.

[0027] The inner bottom surfaces of the upper chamber 2, middle chamber 3 and lower chamber 4 are all inclined planes with an inclination angle ranging from 10° to 30°. The inclined planes assist the downward flow of the drug to reduce unnecessary drug waste.

[0028] Furthermore, the volume of the lower chamber 4 is the same as that of the upper chamber 2. The top of the bag body 1 is provided with a hanging opening 16.

[0029] The entire infusion bag device must use the same solvent, that is, the solvent in all three chambers must be the same. The solvent in the upper chamber 2 and the lower chamber 4 is 50ml of flushing solution (0.9% sodium chloride injection or 5% glucose injection), and the middle chamber 3 is the solvent matched according to the drug (solvent) requirements (0.9% sodium chloride injection or 5% glucose injection). Common specifications are 100ml, 250ml, and 500ml.

[0030] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
