Abstract
The utility model relates to a four-way puncture needle type blood sampling pipe. The utility model comprises a test tube, a syringe, a puncture needle head, and a needle bed. An extension pipe provided with two bypassing branch pipes is connected between the puncture needle head and the needle bed. A seal partition is arranged between the two bypassing branch pipes of the extension pipe. A blood sampling test tube is provided with a sealing plug. Two branch pipes arranged on the sealing plug are connected with two branch pipes of a puncture needle through a flexible pipe. The utility model only uses one syringe, the matching disposable puncture needle head, the matching test tube, and a matching test tube plug to realize blood sampling operation. The testing cost can be lowered, and the utility model conforms to medical staff's operating habits. The utility model is suitable for being popularized and used in hospitals.
Description
This utility model relates to a kind of four-way puncture pin type blood sampling test tube, belongs to disposable medical instrument, is particularly useful for sample of blood, drawn.
The method of blood sampling chemical examination was to carry out vascular puncture with syringe clinically in the past, extracted a certain amount of blood in syringe, then will preserve in the blood injecting tube in the syringe, inspect by ready samples again; This form not only complex operation also will be used a large amount of disposable syringes, make the chemical examination cost than higher; Occurred negative pressure test tube blood sampling in recent years, relied in vitro by puncture needle that negative pressure imports test tube with blood, having simplified the blood sampling operation, but, still being difficult to large scale application because negative pressure test tube production cost is higher.
The purpose of this utility model is to provide a kind of four-way puncture pin type blood sampling test tube, utilizes syringe to connect four-way puncture needle and blood sampling test tube, directly blood is extracted within the test tube, to overcome existing negative pressure test tube production cost problem of higher.
The technical solution of the utility model is achieved in that this four-way puncture pin type blood sampling test tube, basic structure comprises and is connected an extension pipe that is provided with two bypass branch between test tube, syringe, piercing needle, needle stand, described piercing needle and the needle stand, being provided with sealing between two bypass branch of extension pipe cuts off, blood sampling test tube is provided with sealing-plug, establishes two arms on the sealing-plug and links to each other with two arms of puncture needle by flexible pipe.
Also be provided with clamp on the flexible pipe of the bypass branch of described four-way puncture pin type blood sampling test tube.
The technical scheme that the four-way puncture needle that this utility model adopts connects blood sampling test tube only needs a syringe and supporting disposable puncture syringe needle, test tube, test tube plug can realize the blood sampling operation, can greatly reduce the chemical examination cost and meet the operation of medical workers custom again, be suitable for applying in hospital.
Describe technology contents of the present utility model in detail below in conjunction with accompanying drawing:
Fig. 1 is among the sketch map figure of this utility model structure: 1, piercing needle 2, needle stand 3, sealing partition 4,5, bypass branch 6,7, flexible pipe 8,9, arm 10, test tube 11, sealing-plug 12, syringe 13, clamp
Operation principle of the present utility model is: the bypass branch 4 of four-way puncture needle, 5 with the arm 8 of test tube sealing-plug, 9 can be by flexible pipe 6,7 fixedly connected (heat seals or bonding), before the blood sampling operation sealing-plug 11 of test tube 10 is built, syringe 12 is connected with four-way Paracentesis needle holder 2, draw blood according to routine operation, blood flows into test tube 10 by bypass branch 4, blood sampling volume can be by scale or the syringe graduation control that marks on the test tube, after blood sampling finishes, test tube is directly inspected by ready samples, the four-way puncture needle abandons together with sealing-plug, syringe then can continue to use, and carries out next one blood sampling operation.If the corresponding different lab works of same patient need be gathered the multitube blood sample, then can after having gathered the first test tube blood sample, clamp be stuck on the flexible pipe 6, test tube sealing-plug 11 is changed on another test tube, unclamping continues to take a blood sample behind the clamp operates.
