Abstract
The utility model relates to a multifunctional disposable medical used hemostix. A slideable piston is disposed in the inner cavity of a blood collecting bottle; a cross piston rod is connected on the lower part of the piston by screw; a cylinder threaded head and a cross rod body of the piston rod are both beakable structures; when the piston is slid to the lower end of the blood collecting bottle, the cross rod body can be broken from the cylinder threaded head by pulling the rod body left and right, or back and forth, thereby the blood collecting bottle is disposable. After a syringe needle seat is pulled and separated from the blood collecting bottle cover, a seal cover can be covered and connected on the blood collecting bottle cover to change the blood collecting bottle into a blood storage bottle to realize multifunction. The blood collecting bottle is made of polypropylene thermoplastic resin with low cost. The hemostix of the utility model is disposable, can prevent blood cross contamination; and achieves the advantages of multi-function, safety, sanitation, breakage-prevention, safe transportation, simple and convenient use and low manufacturing cost.
Description
Technical field
This utility model relates to a kind of medical liquid sample harvester, especially relates to a kind of medicinal blood harvester, belongs to the medical appliance field.
Background technology
The medicinal blood harvester is widely used in the human body collection and extracts blood.Using common syringe blood collection device at present is a kind of suction type single function hemostix, after the needle tubing that is about to take a blood sample is inserted into human vas, the piston in the withdrawing blood taking tube (syringe) slowly, make the inner chamber of blood taking tube (syringe) produce negative pressure, the blood of human body slowly flows under the human pressure in the blood taking tube (syringe), reaches the purpose of blood sampling.
The common syringe hemostix of this kind has only single function of blood sampling, the blood of adopting will be transferred in the storage blood bottle after the blood sampling and store, and has the contaminated shortcoming of blood of adopting; Common syringe hemostix material is potash glass or other specific glass manufacturings, cost is higher, if reuse, blood taking tube (syringe) need be cleaned, sterilizes and to reuse then, the shortcoming of different human body generation cross-contaminations when having blood sampling, some doctor's examples show that doctor's example that cross-contamination takes place for different human blood collections and blood transfusion happens occasionally, have a strong impact on the healthy of people, have shortcoming and defect.
Summary of the invention
The purpose of this utility model provides the medical hemostix of a kind of multifunctional disposable, and the blood that solve present common syringe blood collection device function singleness, collects transfers the technical problem that cross-contamination takes place when reusing different human blood collections and blood transfusion into vulnerable to pollution in the storage blood bottle and common syringe hemostix.
The multi-functional function with common syringe hemostix blood sampling (blood drawing) that is meant of the medical hemostix of described multifunctional disposable has the function of storing blood, blood treatment again, and use is simple, convenient, shifts and transportation safety.Described disposable use be a hemostix only to 1 part of blood blood sampling (blood drawing) with store blood, blood treatment, do not reuse, its material is the lower polypropylene thermoplastic resin of price, cost is lower, can implement disposable use.
The technical solution of the utility model is: the inner chamber of the blood vial that the cylindrical shape thin-walled is transparent have one with the inner chamber close fit and the piston that can slidably reciprocate along inner chamber, piston is the staged spill, the ladder barrel body female thread of piston bottom connects cross piston rod head cylindrical thread, the length of piston rod is greater than the length of blood vial, afterbody stretches out outside the blood vial, it is conical that the blood vial lower openings is, and piston can not be from the lower openings blood vial that slides out.
The whorl of bottleneck of blood vial connects the blood sampling bottle cap of spill, and the blood vial portion of covering is the conical lid mouth of ladder, and inner hollow is communicated with the inner chamber of blood vial.
The afterbody of syringe needle inserts and is fastened on the first half of conical needle headstock, it is conical that the inner chamber of needle holder Lower Half is, covering the conical lid flap of portion with blood vial closes and is connected, can or cover needle holder and blood sampling bottle cap pull-off release, the inner chamber of syringe needle is communicated with the inner chamber of blood sampling bottle cap and the inner chamber of blood vial.
Protective sleeve of syringe needle lower openings, inner chamber are conical covering with the conical needle headstock and are connected, and can or cover protective sleeve of syringe needle and needle holder pull-off release.
Cross piston rod head cylindrical thread is connected with piston lower step cylinder screw threads for fastening.The cross piston rod head cylindrical thread and the cross body of rod are broken formula structures, after blood sampling is finished, when piston slides into the blood vial lower end, about or front and back pull the cross body of rod, the cross body of rod can be fractureed and separate with the head cylindrical thread, cylindrical thread is stayed in the piston lower step cylinder, and the body of rod is taken away, make blood vial become storage blood bottle and use, realize multi-function action.
Needle holder is after the pull-off release of blood sampling bottle cap, can be replaced with seal cover covers and is connected with the blood sampling bottle cap, with the blood sealing gathered in blood vial, making blood vial become storage blood bottle uses, be different from common hemostix after gathering blood, blood transferred in another storage blood bottle, could be for further processing blood, for example transportation, centrifugalize or the like realizes multi-function action.
The manufactured materials of blood vial adopts the polypropylene thermoplastic resin, and transparent, cost is lower, replaces the manufactured materials potash glass of common hemostix, can realize disposable use.
The utlity model has multi-functional, disposable use and prevent blood cross-contamination, safety and sanitation, not cracky transportation safety, easy to use, advantage of low manufacturing cost.
