Abstract
The disposable blood drawing device for assay is a blood drawing device with vacuum type, negative pressure type, exhaust structure and function. The liquid collecting tube can be used as a tube for the test tube, and can be made of glass or medical plastic. Its regulator can be used for closure sealing, controlling blood-sampling speed (when it is used in negative pressure type), and can be used for sampling several times. The drainage tube extends to the inner wall of the test tube to protect the components of the test sample from being damaged by impact force. The exhaust pipe is sleeved with a soft rubber plug, so that the exhaust pipe can be changed into a simple negative pressure type hemospast for use after the vacuum degree is damaged. The outer wall of the test tube is pasted with identification paper, so that a blood sampling person can write names and test items of the blood sampled person conveniently by using a common pen.
Description
This utility model is the disposable hemospast of using about chemical examination blood, belongs to medical apparatus and instruments.
Long-term come, medical department all adopts glass syringe or disposable syringe blood drawing, and then is sub-packed in and does blood count in glass or the disposable use plastic test tube fully and use.The cost height is also inconvenient like this.Adopt the glass syringe blood drawing very easily to cause cross infection.In recent years there are several the utility model patents about disposable chemical examination and haemospasia device in China, and they are: 88219475.5(chemical examination and haemospasia device), the disposable chemical examination and haemospasia device of 90212045.X(exhaust), the disposable chemical examination and haemospasia device of 90212046.8(band negative pressure mechanism), 90214592.4(disposal vacuum chemical examination and haemospasia device), the disposable chemical examination and haemospasia device of 90213285.X(and teat glass adapted).These hemospast utility model patents have been avoided dividing the trouble of Sheng blood sample test tube of packing into again after the above-mentioned employing syringe blood drawing, and have been reduced cost, but all had certain limitation.The purpose of this utility model provides a kind of improved disposable hemospast, combines the characteristics of discharge type, negative-pressure type, vacuum type hemospast.
Fig. 1 shows the structure of disposable hemospast of the present utility model.It is made up of following parts: test tube 1; Drainage tube 2; Test tube lid 3; Exhaustor 4; Sealing-plug 5; Actuator 6; Bipass 7; Pipe joint 8; Flexible catheter 9; Injection handrail 10; Blood drawing pin 11; Blood drawing needle shield 12; Sign paper 13; Rigid plastics sleeve pipe 14.
Actuator 6 is the general parts in the present disposable transfusion device, makes the control transfusion speed and uses.Here parts 6 seal in order to dam and control blood sampling speed, and fractional sample.The material of actuator 6 is a rigid plastics.
Test tube 1 useable glass or non-toxic medical plastic manufacturing.Test tube lid 3 is generally used the medical plastic manufacturing, and the vacuum type hemospast is then made of soft rubber.Exhaustor 4 is used plastic production.When adopting medical plastic to make seal cover 3, but rigid plastics sleeve pipe 14, exhaustor 4 and even sealing-plug 5 equal integrator injection mo(u)ldings, to reduce manufacturing procedure, to reduce manufacturing cost.Sealing-plug 5 can use soft rubber (vacuum type) or plastics (aerofluxus or negative-pressure type) to make.It is material that drainage tube 2 adopts medical soft plastics or medical latex tube, and it extends on the inwall liquid collecting interface of test tube 1, with the damage that is not hit of protection blood sample composition.The material of blood drawing pin 11 is the 1Cr18Ni9Ti rustless steel, is common transfusion needle, and its sheath 12 is used plastic processing.The paper that sign paper 13 can be write for general pen is as pressure-sensitive gummed paper.Remaining part is made of medical plastic, and material and processing charges are all low, is convenient to promote.
When this utility model uses as the vacuum type hemospast, to open actuator 6 drainage tube 2 is communicated with the external world, end (with parts 8 joints) and air pump by bipass 7 join, and make vacuum reach 10
-3About the mmHg post, shut actuator 6, load onto parts 8,9,10,11,12,13 subsequently and just become the vacuum hemospast, the pack that packets, through the sterilization after can use.During use, take off parts 12, hold parts 10, insert blood drawings place to 11, blood enters 1 by parts 9,8,7,2 under suction function and under the pressure of human body or animal body blood itself, shuts 6 after reaching required blood sample amount, make 3 to separate, promptly obtain being equipped with the test tube of blood sample with 1.If will do multinomial analysis to the same personnel of being sampled this moment, then again a unworn test tube 1 and 3 and other parts of linking to each other with 3 join, open 6, utilize negative pressure or exhaust mode can take a blood sample again (concrete operations are stated as follows).Here having embodied another effect of parts 6, also is to the improvement of disposable blood taking device in the past.Required blood specimen collection finishes, and extracts parts 11 routinely, finishes blood sampling.
When this utility model uses as the negative-pressure type hemostix, just need be by aforesaid evacuation step, blood drawing pin 11 is pulled up sealing-plug 5 after inserting and getting the blood position, and 4 and one air extractor is joined, and has just become the negative-pressure type hemospast.After the air extractor work, slowly opening feature 6, and this moment is by the speed of the regulatory function may command blood flow of parts 6.Here embodied another function that increases parts 6 in this utility model again.When this utility model uses as the discharge type hemospast, parts 4 and air extractor are joined, by the endovascular pressure (greater than external atmosphere pressure) of human body or animal body, under the state that takes off parts 5, blood just can flow in the parts 1.
In sum, structure of the present utility model has the characteristics of discharge type, negative-pressure type, the disposable hemospast of vacuum type, can specifically use according to different situation inputs.Owing on the basis of utility model hemostix in the past, increased parts 6, need not pull up 11 need of blood drawing pin again and change new test tube 1 and just can make multinomial blood testing so it can once insert the blood vessel sampling.When parts 6 are used for the negative pressure blood drawing, also can work the function of regulating blood sampling speed.Structurally this utility model contacts the pipe 2 of drain blood with the inwall of test tube 1, blood flows down along 1 inwall, thereby avoided being subject in the blood constituents such as erythrocyte the probability of impact injury, this is very important in blood sample analysis, also greatly facilitates laboratory personnel's operation.Why parts 5 require to adopt can anti-repeatedly puncture and still keep Packed performance, be for fear of this utility model during as the vacuum type hemospast store or use in vacuum can not be used as the probability that vacuum type uses after destroying, because in some occasion, as do not have for the moment air extractor can not be used as negative-pressure type use, in the time of can not be leaned on the discharge type blood drawing by reasons such as blood sampling person are weak, the blood sampling personnel can make entry needle inject that sealing-plug 5 suctions form certain negative pressure with the syringe of band entry needle and the purpose that reaches blood drawing.Use in this case high capacity syringe such as 50C.C for well.The outer wall of this utility model test tube 1 posts sign paper 13(such as pressure-sensitive gummed paper), the cloth matter rubber glue more commonly used than hospital is cheap, just can write by blood sampling people's name and the name that will chemically examine and the labellings such as project that will chemically examine with common ballpoint pen, pencil, pen, otherwise must could on glass or plastic test tube, write word with extraordinary lettering pen.This just provides convenience for vast rural area, the lonely and remote geographic medical worker who is difficult for having bought this pen.
