Description

Technical Field

[0001] This utility model belongs to the field of medical devices, and in particular relates to a dual-channel blood collection device for infants and young children. Background Technology

[0002] In pediatric diagnosis and treatment, blood collection from infants and young children is a fundamental yet highly challenging clinical procedure. Because newborns have blood vessels with a diameter of only 0.3-1.2 mm and a blood volume of approximately 80 ml / kg (compared to only 70 ml / kg in adults), traditional blood collection methods are prone to complications such as hemolysis and tissue damage. To reduce complications and the number of puncture needles required, blood collection using both a blood gas analyzer and a blood collection tube is typically performed in a single puncture.

[0003] Comparing this to Chinese patent CN209661664U, a disposable dual-channel blood collection needle is disclosed, comprising a vacuum blood collection tube. One end of the vacuum blood collection tube has a puncture needle, and the other end has a connector with a vacuum tube. The connector has a connecting tube on its end near the puncture needle. Both the vacuum blood collection tube and the connecting tube are equipped with clamping devices, and adhesive tape is applied to the T-junction area of ​​the connecting tube. By forming a T-junction between the vacuum blood collection tube, the puncture needle, and the connecting tube, and clamping them together, the problem of conventional blood collection needles being inconvenient to use and affecting test results is solved.

[0004] However, the two blood collection ends of the above-mentioned patent are not interchangeable, which reduces the convenience of operation and easily leads to a single blood collection method and reduced adaptability. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this invention is to provide a dual-channel blood collection device for infants and young children to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dual-channel blood collection device for infants and young children includes a collection needle and a tubing assembly for shunt blood collection. One end of the tubing assembly is fitted with an auxiliary component for switching to vacuum tube blood collection. The collection needle is inserted into the tubing assembly at the end furthest from the auxiliary component. The tubing assembly includes a puncture needle with a main line at its end. A three-way connector is located at the end of the main line, and two branch lines are symmetrically arranged at the end of the three-way connector. Each branch line has a connector sleeve at its end and a hemostatic clip installed on each branch line. The auxiliary component includes a base with a connector at its top and a drainage needle at its bottom.

[0008] Furthermore: the puncture needle is fitted with a protective sleeve, and the drainage needle tube is fitted with a protective cap.

[0009] Furthermore, a handle is provided at the connection point between the puncture needle and the main pipeline.

[0010] Furthermore: the main pipeline, the tee pipe, the branch pipeline and the plug sleeve are integrally formed.

[0011] Furthermore, the substrate is rectangular.

[0012] Furthermore, the substrate, the connector, and the drainage needle are all made of polypropylene material and integrally molded.

[0013] Compared with existing technologies, the beneficial effects are:

[0014] 1. The standardized interface of the connector sleeve is compatible with different blood collection devices and has strong adaptability; the plug-in design of auxiliary components (such as the fit between the base and the connector sleeve) facilitates flexible switching between vacuum tubes and collection needles; the symmetrical layout of the pipeline makes the flow more balanced and avoids blood stagnation or blockage.

[0015] 2. With its dual-channel design (collection needle + vacuum tube diversion), multiple blood collections can be completed with just one puncture, avoiding the trauma and pain caused by repeated punctures in traditional methods. It is especially suitable for infants and young children with small blood vessels. It is applicable to scenarios that require multiple blood collection tubes (such as the laboratory and neonatal departments), shortening blood collection time and improving medical efficiency.

[0016] 3. The integrated piping assembly (main line, tee, and branch lines are molded in one piece) simplifies the assembly process and reduces operation steps; the independent control of the hemostatic clip allows for quick switching of blood collection channels without the need for re-puncture; the hemostatic clip can precisely control blood flow and prevent blood backflow or accidental spillage.

[0017] 4. Protective caps on puncture needles and drainage needles should be used to prevent contamination and reduce the risk of infection. Attached Figure Description
