Embodiment Construction

[0096] Below with reference to accompanying drawing, the present invention is further described

[0097] The present invention is a kind of safe self-destruct type blood sampling device, such as figure 1 As shown in , it mainly includes a jacket 1, a mandrel 2, a needle holder 3, a needle tube sheath 4, a rubber stopper 5, and a needle tube 6. The mandrel 2 is arranged inside the jacket 1, and the end of the mandrel 2 is provided with a rubber The end of the plug 5 and the needle holder 3 is provided with a needle tube 6, which is different from the prior art in that: the neck of the end of the outer jacket 1 is sleeved with an outer jacket sealing plug 7, and the outer jacket sealing plug 7 is outer jacketed with the needle holder 3 A safety sleeve 8 is sheathed on the outside of the jacket 1 , a needle sheath 4 is sheathed on the end of the needle base 3 , and an anticoagulant storage tube 10 is arranged inside the needle sheath 4 .

[0098] like Figure 5 As shown in , th...

Abstract

The invention discloses a safety self-destroying hemostix, and is characterized in that a cylinder neck positioned on the end portion of a casing is sheathed with a casing sealing-plug, a needle seat is sheathed outside the casing sealing-plug, a safety casing pipe is sheathed on the outer portion of the casing, and the end portion of the needle seat is sheathed with a needle tube sheath in which an anticoagulant storage tube is arranged. The invention has the advantages of reasonable structure, novel design conception, easy and flexible manipulation, and convenient and fully automatic assembly. The production is an overall plastic element, thus the cost is low, the production also has a safety device which can effectively prevent the accidental injure of medical staff in manipulation and avoid accidental infection, the production realizes self-destroying step by step in using process, the dismounting components can not be assembled again, thereby the actual complete self-destroying is realized. By applying the invention, a used hemostix cannot be used again, and the shortages and defects existing in the prior productions are overcome.

Description

Technical field: [0001] The invention relates to the technical field of medical devices, in particular to a blood sampling device with safety protection and self-destruction functions, and in particular to its mechanical connection structure. Background technique: [0002] Most of the general medical applicators and syringes have the same structure, including a jacket, a needle seat with a needle tube assembled at the end of the jacket, and a core rod with a rubber stopper assembled in the inner cavity of the jacket, and the rubber stopper With the reciprocating movement of the core rod in the inner cavity of the jacket, the negative pressure in the cavity can suck blood or liquid medicine and other fluids into or out of the inner cavity of the jacket through the needle tube, the only difference is that the blood collection device must also contain anticoagulant A device that is sucked into the jacket to prevent clotting of the blood that is sucked into the jacket.
