Abstract
A blood sampling needle for a clinical laboratory comprises a needle head and a syringe. A rubber tube with a handle is arranged at the joint of the syringe and the needle head and is sleeved outside the needle head, the handle is arranged close to the needle head and shaped in a wing, the width of the handle is not larger than the diameter of the syringe of the blood sampling needle, a plastic sleeve is arranged outside the needle head, an inner thread is arranged at an internal edge opening of the plastic sleeve, and an outer thread is arranged on the outer portion of the syringe. The blood sampling needle for the clinical laboratory has the advantages that the rubber tube is arranged on the portion of the needle head of the blood sampling needle, the length of the rubber tube can be adjusted to determine exposed area of the needle head via the handle, and when the exposed area is increased, the blood sampling needle convenient to operate by lifting the handle upwards, the extending depth of the blood sampling needle can be adjusted according to patient conditions during blood sampling; and the plastic sleeve sleeved outside the needle head is used for protecting the tip of the needle head from being polluted.
Description
Technical field
This utility model relates to a kind of blood sampling instrument, particularly a kind of clinical laboratory blood taking needle.
Background technology
The blood taking needle that some hospitals use adopts three edged needle more, because be not disposable blood taking needle, needs sterilization, if sterilization thoroughly can not cause cross infection, has brought unnecessary injury to the patient.In recent years, blood taking needle had adopted disposable more, and because the bad grasp of the degree of depth of blood sampling, it is undesirable to get the blood effect, and it is also very inconvenient to operate.Because needle point exposed after blood taking needle had been adopted blood, accidentally injured easily patient and medical personnel, the needle point that exposes is also contaminated easily.
Summary of the invention
The purpose of this utility model is difficult to regulation and control in order to solve the blood sampling degree of depth, and the exposed problem of easily polluting of needle point provides a kind of clinical laboratory blood taking needle.
Described purpose realizes by the following method:
A kind of clinical laboratory blood taking needle comprises syringe needle, and needle tubing is that described needle tubing and syringe needle junction are provided with the rubber tube with handle, and rubber sleeve is in the outside of syringe needle.
Above-mentioned a kind of clinical laboratory blood taking needle is that described handle arranges near the syringe needle place, and handle becomes wing.
Above-mentioned a kind of clinical laboratory blood taking needle is that the width of described handle is no more than the diameter of the needle tubing of blood taking needle.
Above-mentioned a kind of clinical laboratory blood taking needle is that described syringe needle is provided with plastic bushing outward, and the internal edges mouth place of plastic bushing is provided with female thread, and the needle tubing outside is provided with external screw thread.
The utility model has the advantages that the needle section at blood taking needle is arranged with rubber sleeve, can utilize handle to adjust the size of syringe needle bare area, the degree of depth that will penetrate in the time of also can regulating blood sampling according to patient's situation; Outer cover at syringe needle has vinyl cover, for the tip portion that prevents syringe needle contaminated.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Wherein, syringe needle 1, needle tubing 2, rubber tube 3, handle 4, plastic bushing 5.
The specific embodiment
Elaborate this utility model preferred embodiment below in conjunction with accompanying drawing.
This utility model provides a kind of clinical laboratory blood taking needle; comprise syringe needle 1; needle tubing 2; needle tubing 2 is provided with rubber tube 3 with syringe needle 1 junction, and rubber tube 3 is enclosed within the outside of syringe needle, and rubber tube 3 is provided with handle 4; handle 4 arranges near the syringe needle place; 4 one-tenth wings of handle, the length that can utilize handle to adjust rubber sleeve is determined the size of syringe needle bare area, when bare area increases; handle upwards draws; at this moment, rubber sleeve is because making of being bent upwards of external force increased the bare area of syringe needle; handled easily; the width of handle is no more than the diameter of the needle tubing of blood taking needle, is provided with plastic bushing 5 outside the syringe needle 1, and the internal edges mouth place of plastic bushing 5 is provided with female thread; the needle tubing outside is provided with external screw thread; sleeve pipe is screwed in the needle tubing outside, has both protected syringe needle, has also prevented the pollution of dust.
Two sleeve structures that the described rubber tube 3 of present embodiment also can be arranged to be threaded when needs are adjusted the length of rubber tube, get final product by the sleeve pipe of screwing the below.
Present embodiment is the protection domain that the exemplary illustration of this patent is not limited it; those skilled in the art can also carry out the part to it and change; as long as no the spirit that exceeds this patent, all be considered as the replacement that is equal to this patent, all within the protection domain of this patent.
