The utility model discloses a blood transfusion device with a nondestructive needle, which comprises the nondestructive needle, a speed regulator and a dripping cylinder, and are sequentially connected in series through a transfusion leather strip. The nondestructive needle comprises a needle handle and a needle rod, wherein the front end of the needle rod is provided with a beveled needle point, the needle point is provided with a plug for blocking the opening of the needle point, and a guide wire is arranged in the needle rod. The utility model can effectively avoid the core forming effect of the needle hole and avoid the needle head from damaging the silica gel pad of the transfusion port; meanwhile, when the intravenous puncture is directly performed, the intravenous puncture needle can also flow back into the infusion leather strap through the blood leakage hole, so that an operator can conveniently judge the position of the needle head. The utility model is applicable to patients placed in the transfusion ports, can directly perform venipuncture, has high universality, has little damage to the patients and the transfusion ports, and can be widely applied to clinical treatment.

Description

Blood transfusion device with nondestructive needle

Technical Field

The utility model relates to the field of medical instruments, in particular to a blood transfusion device with a nondestructive needle.

Background

Blood transfusion sets are infusion devices that establish blood and venous access. Because the bottle stopper puncture outfit of the common blood transfusion device is sharp, the socket end of the blood transfusion bag for clinical use is short, the blood product packaging bag (blood bag) is thin and soft, and nurses often have the phenomenon that the needle of the blood transfusion device punctures the blood bag due to improper puncture methods, so that the blood product is wasted and polluted, even the trouble of nursing is caused, and the nursing staff is greatly puzzled.

Most of the existing non-invasive needle infusion apparatuses or blood transfusion apparatuses are matched with an infusion port for use, for example, CN202111042171.7 discloses a non-invasive needle with a piston device, but when the non-invasive needle is inserted, blood cannot enter an infusion leather strap through a needle rod, whether a needle point is placed in a proper position of a blood vessel cannot be judged, and the non-invasive needle can only be matched with the infusion port for use, so that vein puncture cannot be performed independently.

Disclosure of Invention

The present utility model aims to overcome the above problems and to provide a blood transfusion apparatus with a non-invasive needle. In order to achieve the above purpose, the utility model adopts the following technical scheme:

a blood transfusion device with a nondestructive needle comprises the nondestructive needle, a speed regulator and a dripping cylinder, which are sequentially connected in series through a transfusion leather strip;

the nondestructive needle comprises a needle handle and a needle rod, wherein the front end of the needle rod is provided with a beveled needle point, the needle point is provided with a plug for blocking an opening of the needle point, a guide wire is arranged in the needle rod, the needle handle is provided with a guide wire outlet hole, the diameter of the guide wire is smaller than the inner diameter of the needle rod, one end of the guide wire is fixedly connected with the plug, the other end of the guide wire extends to the outside of the needle handle after passing through the needle rod and the guide wire outlet hole, the tail end of the guide wire is provided with a pull ring, a groove is arranged in the needle handle corresponding to the guide wire outlet hole, and a sealing gasket is arranged in the groove and is smaller than the depth of the groove;

and the plug is provided with a blood leakage hole.

As an improvement, the blood leakage hole is in a strip shape.

As an improvement, shielding parts for preventing the plugs from falling off are arranged at the top and the bottom of the opening of the needle point.

As an improvement, a blood filter screen is arranged in the dripping cylinder.

As an improvement, the guide wire passes through the sealing gasket and then extends out from the guide wire outlet hole.

The utility model has the advantages that:

the utility model can effectively avoid the core forming effect of the needle hole and avoid the needle head from damaging the silica gel pad of the transfusion port; meanwhile, when the intravenous puncture is directly performed, the intravenous puncture needle can also flow back into the infusion leather strap through the blood leakage hole, so that an operator can conveniently judge the position of the needle head.

The utility model is applicable to patients placed in the transfusion ports, can directly perform venipuncture, has high universality, has little damage to the patients and the transfusion ports, and can be widely applied to clinical treatment.
