Description

Disposable angled dosing needle

technical field

The utility model relates to the technical field of medical equipment, in particular to a disposable medicine-feeding needle with folded corners.

Background technique

At present, the process of adding medicine to the intravenous infusion is achieved clinically by using a syringe to pump the medicine into the infusion bottle. The syringe is used as a bridge for the medicine to enter the infusion bottle. During the operation, the pulling piston is easy to touch the operator's hand and the piston pulling process. Extensive contact with the surrounding air in the environment, there is a risk of contaminating the liquid medicine; in view of the above problems, a related dosing device has been proposed in the prior art, as follows:

Existing technology one: dosing needle application number: CN201020210066.0

When dispensing medicine, the needle can insert the lower needle into a bottle of liquid medicine, and then insert the other bottle upside down into the upper needle, and the medicine liquid in the upper bottle can automatically flow into the lower bottle without special operation, which effectively relieves the It reduces the workload of medical staff and improves work efficiency; there is a support platform between the upper needle and the lower needle to support the medicine bottle inserted on the upper needle; but this structure has the following disadvantages, one: only two bottles of medicine The liquid is all sealed bottled liquid medicine, and cannot be used for sawn ampoule dosing, but clinically, ampoule bottle liquid medicine occupies a relatively large proportion, and its use has limitations; two: use the weight of the liquid to flow from the upper bottle to the lower bottle, If the upper and lower bottles are glass bottles, the flow rate of the liquid medicine will be affected by the pressure in the bottle, and the flow rate will slow down or even stop, which will affect the work efficiency; 3: There is a support platform between the upper needle and the lower needle to support the upper needle. The medicine bottle inserted on the needle, if the medicine bottle is big and small at the bottom, the support table will not be able to play a role, and the dosing process cannot be completed; 4: At present, the clinical infusion bottle is basically a plastic bottle, and the standing stability of the plastic bottle is poor. Medicine needles are not suitable for adding medicine to plastic bottles.

Existing technology 2: Two-way dosing needle Application number: 200820020034.7

The two-way drug dosing needle avoids the disadvantages of easily polluting, inconvenient, and reducing work efficiency in the process of first sucking the drug liquid into the empty needle when adding the drug, and then adding it to the liquid bottle through the needle; The structure has the following disadvantages: 1: It is limited to the operation that both bottles of medicinal liquid are sealed bottled medicinal liquid, and cannot be used for adding medicine to sawed ampoules, but clinically, the medicinal liquid in ampoules occupies a relatively large proportion, so the use is limited; Two: Use the weight of the liquid to flow from the upper bottle to the lower bottle. If the upper and lower bottles are glass bottles, the flow rate of the liquid medicine will be affected by the pressure in the bottle, and the flow rate will slow down or even stop, affecting work efficiency.

Existing Technology 3: Application No. 200920018706.5 for Medical Dosing Needle

The medical dosing needle comprises a needle seat, two interconnected needle bodies are arranged at both ends of the needle seat, and a first filter is arranged in the needle seat. The advantages of the medical dosing needle are simple structure, convenient use, saving time and labor for dosing, reducing the pollution of medicinal liquid, and ensuring the safety of infusion for patients. However, this structure has the following disadvantages: one: it is limited to the operation that both bottles of medicinal liquid are sealed bottled medicinal liquid, and cannot be used for adding medicine to sawed ampoules, but clinically, the medicinal liquid in ampoules occupies a relatively large proportion, so the use is limited Two: This structure uses the weight of the liquid to flow from the upper bottle to the lower bottle. If the upper and lower bottles are glass bottles, the flow rate of the liquid medicine will be affected by the pressure in the bottle, and the flow rate will slow down or even stop, affecting work efficiency.

Prior art 4: Disposable fully-sealed dosing needle Application number: 201210443370.3

The disposable fully-sealed dosing needle is composed of a dosing needle, a dosing hose or a dosing needle, a dosing hose and a pressure-regulating scalp needle; two ends of the dosing hose are equipped with dosing needles, The dosing needles are divided into A-type dosing needles with side holes and B-type dosing needles with end holes; pressure regulating scalp needles include pressure regulating needles and hoses. This one-time fully-sealed dosing needle is suitable for the dosing operation of all rubber stoppered medicine bottles, liquid bottles, etc., and makes use of the pressure difference and sterile gas in the medicine bottle and liquid bag to make the dosing process in a closed state. It can be completed under the environment, which reduces the probability of drug contamination. However, this structure has the following disadvantages: 1: the structure is a hose feeding needle, which is not easy to fix when operated by a single person, which affects the efficiency of dosing; Sawed ampoules are used for dosing, but clinically, ampoules occupy a large proportion of liquid medicine, so the use is limited.

In view of the above problems, a disposable angled needle for adding medicine is proposed.
