Abstract
The utility model discloses a rubber sheath for a blood taking needle, belongs to the field of the medical instrument and particularly relates to a blood needle sheath. The rubber sheath comprises a sheath body and is characterized in that a bulge concaved inwards is arranged at the top end of an inner chamber of the sheath body. The rubber sheath can effectively plug a needle hole and prevents the external air from entering and blood samples from flowing back and leaking, thereby not only being sanitary and environment-friendly, but also guaranteeing the safety of blood samples and protecting a needle point. Besides, an expansion ring is arranged at the tail end of the sheath body, so that the sheath has flexibility and elasticity to be capable of sticking tightly to the root part of a needle head and having low probability of dropping off.
Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of blood needle shield.
Background technology
The vacuum blood collection device utilizes principle of negative pressure suction sample of blood, drawn, extracts after the blood taking needle that device is equipped with thrusts the human blood collection position, and outside syringe needle was exposed to, pin hole was communicated with ambient atmos, easily the blood sample in the device for storing liquid is polluted.And the blood in the blood-taking device refluxes through the blood sampling pin hole that is in communication with the outside easily, causes unnecessary sample losses.
Summary of the invention
This utility model technical problem to be solved provides a kind of blood taking needle and uses rubber sheath, is convenient to protect blood taking needle, prevents that blood from refluxing.
For solving the problems of the technologies described above, the technical scheme of this utility model is: provide a kind of blood taking needle to use rubber sheath, comprise the sheath body, it is characterized in that: the inner chamber top of sheath body is provided with the indent convexity.
The end of sheath body is provided with expansion ring.
The beneficial effect of this utility model is:
1, the inner chamber top of sheath body is provided with the indent convexity, and effective shutoff pin hole when preventing that outside air from getting into, has been avoided blood sample to reflux and leaked, and not only hygienic environment-protecting but also guaranteed the safety of blood sample has been protected needle point.
2, the sheath body tip is provided with expansion ring, makes sheath itself have telescopic resilience, can fit tightly the syringe needle root, difficult drop-off.
3, this utility model is simple in structure, and cost of manufacture is low, and Practical Performance is good, suits in the industry cycle to popularize.
Description of drawings
Fig. 1 is the structural representation of this utility model;
Fig. 2 is the cutaway view of this utility model;
Among the figure: 1, sheath body; 2, expansion ring; 3, indent is protruding.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is described in further detail.
Like Fig. 1, shown in 2, the described a kind of blood taking needle of this utility model is used rubber sheath, and the cecum of sheath body 1 is defined as the top, and the opening end of sheath body 1 is defined as end.
The inner chamber top of sheath body 1 is provided with that indent is protruding 3, and effectively the shutoff pin hole when preventing that outside air from getting into, has avoided the blood sample backflow to leak, and not only hygienic environment-protecting but also guaranteed the safety of blood sample has been protected needle point.The end of sheath body 1 is provided with expansion ring 2, makes sheath itself 1 have telescopic resilience, can fit tightly the syringe needle root, difficult drop-off.
It is to be noted; Above-mentioned embodiment only is this utility model preferred embodiment; For those skilled in the art, under the prerequisite that meets this utility model operation principle, any be equal to or similar replacement all falls in the protection domain of this utility model.
