Description
Technical Field
The utility model relates to a medical treatment appurtenance field, concretely relates to blood culture bottle sample collection system.
Background
Blood culture is the most important means for diagnosing bacteremia, and generally, when blood is cultured, the blood needs to be injected into a blood culture bottle and put into an instrument for culture, when bacteria grow in the bottle, an alarm system of the instrument is triggered, and at the moment, a syringe is used for drawing the blood in the blood culture bottle for smear dyeing and subsequent inspection.
However, in general, a blood culture bottle generates gas after bacteria grow, so that the gas pressure in the bottle is high, and the gas in the bottle is high, so that the gas in the blood culture bottle is easily sprayed out of a blood sample by a syringe in the process of blood drawing to cause infection and injury to operators.
In addition, when a sample needs to be extracted from a blood culture bottle in the prior art, a syringe with a needle is usually directly adopted, the needle is inserted into the blood culture bottle, then a piston of the syringe is pulled to suck the sample in the blood culture bottle, after the suction is finished, the needle needs to be pulled out of the blood culture bottle, the collected sample can be used for the next detection, and the needle can stab an operator to cause cross infection in the process of pulling out the needle.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a blood culture bottle sample collection device to avoid the sample blowout and produce infection and injury to operating personnel when the extraction sample.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model provides a blood culture bottle sample collection system, includes syringe and connecting pipe, connecting pipe fixedly connected with syringe needle, install on the connecting pipe and be used for carminative exhaust unit, the nipple of syringe with the cooperation can be dismantled to the connecting pipe.
The principle and the advantages of the scheme are as follows: during the in-service use, because fixedly connected with syringe needle itself on the connecting pipe in this scheme, consequently need not to remain the syringe needle on the syringe when using the syringe, only need insert the syringe needle on the connecting pipe in the blood culture bottle during the use, and make the syringe needle on the connecting pipe be located the sample top of blood culture bottle, and exhaust through exhaust unit, thereby make the atmospheric pressure in the blood culture bottle reach balanced with external atmospheric pressure, avoid among the prior art in the in-process of extraction sample because the atmospheric pressure in the blood culture bottle is big and produce the blasting or lead to the blood sample spun condition, and then avoid appearing the blood sample spill and produce the infection to operating personnel and operational environment.
In this scheme, after accomplishing the exhaust in to blood culture bottle, be connected with the connecting pipe through making the syringe to use the sample in the syringe extraction blood culture bottle, after the syringe absorbs the sample, need not to extract blood culture bottle with the syringe needle on the connecting pipe, only need this moment with the syringe from the connecting pipe take out can. In the mode of the scheme for extracting the specimen, the condition that the needle head of the injector is inserted into the blood culture bottle to extract the specimen and the needle head on the injector is required to be pulled out together after the specimen is extracted in the prior art is avoided, the needle head on the injector can stab an operator to cause infection when the injector is pulled out in the prior art, however, in the technical scheme, after the needle head on the connecting pipe is inserted into the blood culture bottle, the connecting pipe and the needle head are not required to be pulled out, only the nipple of the injector is required to be communicated with the connecting pipe to suck the specimen, after the specimen is sucked, the collected specimen can be sent to the next step to be detected by pulling the injector out of the connecting pipe, and because the needle head is not arranged on the injector in the scheme, the condition that the operator is stabbed when the injector is pulled out is avoided, and the occupational exposure risk is effectively avoided, avoiding the infection of the operators.
Preferably, as an improvement, the connecting pipe is T type structure, and the connecting pipe includes the standpipe and the violently pipe of mutually perpendicular setting, the one end and the syringe needle of standpipe are connected, the other end of standpipe with violently manage the intercommunication, the nipple of syringe inserts the one end of violently managing, exhaust unit is located the other end of violently managing.
The connecting pipe is T type structure in this scheme for the standpipe of connecting pipe is connected with the syringe needle, thereby is convenient for insert in the blood culture bottle, and the both ends of violently managing are used for being connected with the nipple and the exhaust unit of syringe respectively, its simple structure convenient operation.
Preferably, as an improvement, the vertical tube and the horizontal tube are integrally formed.
So set up, make the processing more convenient, and manufacturing cost is lower.
Preferably, as an improvement, the connecting pipe includes fixed pipe and blast pipe of coaxial setting, the both ends of fixed pipe are the opening end, the one end of fixed pipe is fixed with the syringe needle, the other end of fixed pipe is located in the blast pipe, and fixed pipe and blast pipe threaded connection, the exhaust unit is installed on the blast pipe, the blast pipe can be followed fixed intraductal the back-out, the nipple of syringe can insert in the fixed pipe.
This scheme provides the structure of another kind of connecting pipe, and the connecting pipe in this scheme includes fixed pipe and blast pipe, and fixed pipe and blast pipe threaded connection, and the exhaust unit is installed on the blast pipe, insert the syringe needle on the connecting pipe in the blood culture bottle when using after exhausting, through the blast pipe back-out on with fixed pipe, the nipple of syringe is inserted to fixed pipe top again this moment, make the syringe extract the syringe with the blood sample in the blood culture bottle in, also need not to extract the syringe needle from the blood culture bottle in this scheme, thereby the effectual condition of having avoided the puncture produces, and the connecting pipe simple structure in this scheme, small, unusual practicality.
Preferably, as a modification, the exhaust unit is a check valve, and the check valve allows the gas in the connecting pipe to flow from inside to outside.
Exhaust unit adopts the check valve in this scheme, makes the interior gas of blood culture bottle outwards discharge only, and in external air can not enter into the blood culture bottle to ensure that quick gas to in the blood culture bottle carries out carminative operation.
Preferably, as a modification, the connecting tube is a rigid tube made of plastic.
So set up, the connecting pipe is the hard tube, and the convenience is through this connecting pipe steady insert the blood culture bottle with the syringe needle in, and can strengthen the dynamics when inserting the syringe needle at the in-process connecting pipe that inserts the syringe needle, makes the syringe needle difficult for rocking inserting the in-process, makes things convenient for direction and the degree of depth that the control syringe needle inserted the blood culture bottle, uses safelyr.
