Abstract
The utility model discloses a real-time sampling device for blood culture bottle pressure detection. The device comprises a sampling component and a pressure detection component arranged at the opening of a blood culture bottle, wherein the sampling component and the pressure detection component are integrally arranged; the sampling component comprises a sampling needle stretching into the blood culture bottle; the tail end of the sampling needle is connected with a sampling extrusion rod; the head end of the sampling needle is sleeved with a sampling needle sterile needle sleeve; the pressure detection component comprises a pressure detection needle stretching into the blood culture bottle; the head end of the pressure detection needle is sleeved with a pressure detection needle sterile needle sleeve; a tail end sensing interface of the pressure detection needle is connected with a pressure sensing detector. The device has the advantages that due to the design, the defects that for a conventional instrument, unattended operation or real-time detection cannot be achieved, the culture time cannot be strictly controlled, and the like are overcome, unattended automatic operation is achieved in the whole process, the labor and the material are saved, the real-time property and the accuracy of detection data are ensured, the improvement cost is low, and device is applicable to various medical and research and development institutions.
Description
Technical field
The utility model relates to the detection sampling unit that clinical blood sample is carried out to blood cultivation, refers to particularly a kind of for Blood culture bottle pressure detection real time sample device.
Background technology
At present, except only a few hospital has purchased semi-automatic, automated blood culture system, most of hospital particularly basic hospital microbial culture still continues to use Erlenmeyer flask making blood culture medium outmoded, that fall behind, its substratum is made, sampling operation is loaded down with trivial details, bottleneck footpath is large, expose widely, extraneous bacterium very easily enters in substratum and pollutes, and also increases the risk of reviewer's cross infection simultaneously; And adopt semi-automatic, automated blood culture system inspection training method still to be unable to do without reviewer on duty, need to carry out fixed cycle operator, cannot realize the requirement such as unmanned, real-time inspection, especially cannot strictly control incubation time.
Summary of the invention
The purpose of this utility model is exactly to want, and avoids the defect of prior art, provide a kind of simple in structure, economical and practical, can realize unmanned, real-time inspection for Blood culture bottle pressure detection real time sample device.
For achieving the above object, the utility model designed for Blood culture bottle pressure detection real time sample device, comprise the sampling assemble and the pressure detecting assembly that are arranged on Blood culture bottle bottle mouth position, it is characterized in that: described sampling assemble and pressure detecting assembly integrated setting, described sampling assemble comprises the sampling probe stretching in Blood culture bottle bottle, described sampling probe tail end is connected with sampling extrusion stem, and described sampling probe head end cover has the aseptic needle guard of sampling probe; Described pressure detecting assembly comprises the pressure detection pin stretching in Blood culture bottle bottle, and described pressure detection needle end cover has the aseptic needle guard of pressure detection pin, and tail end sensing interface is connected with pressure sensing detector.
The utility model has the advantage of: the design has solved existing instrument and cannot realize unmanned, real-time inspection and cannot strictly control the defects such as incubation time, whole process realizes unmanned formula automatic operation, save manpower and materials, also ensured the real-time accuracy of check data; Improving cost is cheap, is applicable to various medical treatment, R&D institution's use.
Brief description of the drawings
Fig. 1 is a kind of scheme of installation for Blood culture bottle pressure detection real time sample device.
Fig. 2 is a kind of exploded perspective view for Blood culture bottle pressure detection real time sample device.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Shown in figure for Blood culture bottle pressure detection real time sample device, comprise the sampling assemble and the pressure detecting assembly that are arranged on Blood culture bottle 1 bottle mouth position, sampling assemble and pressure detecting assembly integrated setting, sampling assemble comprises the sampling probe 2 stretching in 1 bottle of Blood culture bottle, sampling probe 2 tail ends are connected with sampling extrusion stem 3, and sampling probe 2 head end covers have the aseptic needle guard 4 of sampling probe; Pressure detecting assembly comprises the pressure detection pin 5 stretching in 1 bottle of Blood culture bottle, and pressure detection pin 5 head end covers have the aseptic needle guard 6 of pressure detection pin, and tail end sensing interface 5.1 is connected with pressure sensing detector.
Principle of the present utility model is: when use, first in Blood culture bottle 1, pack substratum into, then blood sample sample is carried out to culture experiment on substratum, the utility model is contained in to Blood culture bottle 1 bottle mouth position, make its seal inside, ensure culture effect; Blood culture bottle 1 is placed on to cultivate on instrument and waits for that its culturing process finishes, when Blood culture bottle 1 internal pressure changes, be that blood sample is while having cultivated, pressure of the inside of a bottle detects pin 5 and pressure change detected, signal is transferred to pressure sensing detector by sensing interface 5.1, pressure sensing detector presses sampling extrusion stem 3 by link gear, gather cultured blood sample through sampling probe 2, enter again next and detect analysis link, whole process realizes unmanned formula automatic operation, save manpower and materials, also ensured the real-time accuracy of check data; Improving cost is cheap, is applicable to various medical treatment, R&D institution's use.
