The utility model discloses make the needle not expose when taking a blood sample, and can not see needle and blood by the blood sampling person.
Description
Technical Field
The utility model relates to the technical field of medical equipment, specifically a novel hemostix.
Background
At present, when finger blood sampling is carried out, a finger is generally punctured by a needle firstly, and then the finger is squeezed to extrude blood, and the mode has the following defects:
1. when the finger is punctured by the needle, the needle is exposed, and the medical staff is easily punctured by the needle;
2. the needle is easily contaminated when exposed;
3. when blood is collected, a blood-sampled person can see the needle and blood, so that the blood-sampled person is easy to have blood-sickness.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a novel hemostix is provided, which makes the needle not exposed when blood sampling, and the needle and blood can not be seen by the blood sampling person.
In order to solve the technical problem, the utility model provides a novel hemostix, it includes:
the blood sampling sleeve is elastic, a blood sampling cavity is arranged in the blood sampling sleeve, and the blood sampling cavity is provided with an opening end;
a needle feeding mechanism which is arranged in the blood sampling cavity and can generate elastic deformation due to the extrusion of the blood sampling sleeve;
and the needle is fixed on the needle feeding mechanism and can extend out or retract into the opening end of the blood collection cavity according to the elastic deformation of the needle feeding mechanism.
Preferably, the needle feeding mechanism is a diamond-shaped elastic frame, the front end of the elastic frame faces the opening end of the blood collecting cavity, and the needle is fixed at the front end of the elastic frame.
Preferably, the blood collecting sleeve is sleeved with a protective sleeve.
Preferably, the novel blood collector also comprises a cap which is sleeved on the protective sleeve to seal the open end of the blood collecting cavity, and the cap is provided with a needle sleeve which is sleeved on the needle.
Preferably, a groove is formed in the inner wall of the cap, and a convex point used for being clamped into the groove is arranged on the protective sleeve.
After the structure more than adopting, compared with the prior art, the utility model, have following advantage:
the utility model discloses a hemostix is when taking a blood sample, the open end in the chamber of will taking a blood sample sticiss at the blood sampling position, then pinch the blood sampling cover with the hand, make send needle mechanism to warp so that the needle stretches out from the open end in blood sampling chamber, make the needle puncture skin, and the blood sampling chamber can contract when pinching the blood sampling cover with the hand, and like this, after the skin is punctured to the needle, loosen the blood sampling cover, make the blood sampling cover kick-back, thereby make the blood sampling chamber expand, can form suction to the blood sampling position during the blood sampling chamber expansion, thereby with blood by puncture department's suction, the blood is inhaled the blood sampling intracavity, and like this, the utility model discloses a hemostix does not expose when taking a blood sample, can avoid the acupuncture to hinder medical staff, also can avoid the needle to expose and be contaminated, and can not see needle and blood by the blood sampling person at the in-process of taking a blood sample, can avoid appearing the condition of dizzy blood by the blood sampling person.

fig. 3 is a schematic structural diagram of the present invention when the cap is put on.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1, 2 and 3, the novel blood collector of the present invention comprises a blood collecting sleeve 10, a needle feeding mechanism and a needle 20.
The needle feeding mechanism is arranged in the blood sampling cavity 11 and can be elastically deformed due to the extrusion of the blood sampling sleeve 10, so that when the blood sampling sleeve 10 is squeezed, the blood sampling sleeve 10 can extrude the needle feeding mechanism, the needle feeding mechanism is elastically deformed, and when the blood sampling sleeve 10 is loosened, the needle feeding mechanism is restored to the original state.
The needle 20 is fixed to the needle feeding mechanism, and the needle 20 can be extended or retracted to the open end 1 of the blood collection chamber 11 according to the elastic deformation of the needle feeding mechanism.
The needle feeding mechanism is a rhombic elastic frame 30, the front end of the elastic frame 30 is aligned with the opening end 12 of the blood collection cavity 11, and the needle 20 is fixed at the front end of the elastic frame 30, so that when the left side and the right side of the elastic frame 30 are relatively extruded, the front end of the elastic frame 30 can extend forwards, and when the elastic frame 30 is released, the elastic frame 30 restores the original state, so that the front end of the elastic frame 30 retracts.
The blood collecting sleeve 10 is sleeved with a protective sleeve 40.
The novel blood collector also comprises a cap 50 which is used for being sleeved on the protective sleeve 40 to seal the open end of the blood collecting cavity 11, and the cap 50 is provided with a needle sleeve 51 which is used for being sleeved on the needle 20, so that the cap 50 can prevent the inside of the blood collector from being polluted before the blood collector is used, and can prevent the blood collector from being used for a second time after the blood collector is used.
The inner wall of the cap 50 is provided with a groove, and the protective sleeve 40 is provided with a convex point 52 used for being clamped in the groove, so that when the cap 50 is sleeved on the protective sleeve 40, the convex point 52 is clamped in the groove, and the cap 50 is fixed firmly.
The utility model discloses a hemostix is when taking a blood sample, open end 12 with blood sampling chamber 11 sticiss at the blood sampling position, then squeeze the both sides of holding between the fingers blood sampling cover 10 with the hand, make send needle mechanism to warp so that needle 20 stretches out from the open end 12 of blood sampling chamber 11, make needle 20 puncture skin, and blood sampling chamber 11 can contract when squeezing the fingers blood sampling cover 10 with the hand, and thus, puncture skin at needle 20 after, loosen blood sampling cover 10, make blood sampling cover 10 kick-back, thereby make blood sampling chamber 11 expand so that blood sampling chamber 11 resumes original state, can form suction to the blood sampling position when blood sampling chamber 11 expands, thereby with blood by puncturing the department suction, blood is inhaled in the blood sampling chamber 11.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention, but should not be construed as limiting the claims, and the present invention is not limited to the above-described embodiments, but may be modified in various ways. In summary, all changes that can be made within the scope of the independent claims of the present invention are within the scope of the present invention.
