Description

An umbilical cord blood sampling device

technical field

The utility model relates to the technical field of cord blood collection and sampling, in particular to a cord blood collection and sampling device.

Background technique

Hematopoietic stem cells are currently the most in-depth research and the most widely used in clinical practice. Their main sources are: bone marrow, peripheral blood, and neonatal umbilical cord blood. Among them, umbilical cord blood hematopoietic stem cells have rich sources, and the collection is not harmful to mothers and babies. It is the best way to obtain hematopoietic stem cells due to its advantages such as low matching requirements and ready-to-use. At present, for the collection of umbilical cord blood, the umbilical cord blood collection device is mainly used, and the collection procedure is as follows:

1. Make preparations before collection; 2. After the baby is born, tie the umbilical cord and cut it from the middle; 3. Hang the placenta and fully disinfect the pricking site; 4. Puncture the umbilical cord and collect the cord blood collection device The bag is lower than the placenta and umbilical cord, and the gravity of the blood is used to make the blood flow into the collection bag automatically; 5. During the collection process, it is necessary to shake the collection bag while collecting, so that the anticoagulant in the collection bag can be fully mixed with the blood without causing 6. After the collection, raise the blood collection needle so that all the blood in the pipeline flows into the collection bag, and seal the collection bag; 7. Do a good job in the treatment of medical waste, and carry out corresponding records, labels, and packaging. Although the existing umbilical cord blood collection device is simple to use, the operation is not convenient enough, especially when sampling, the operation is cumbersome, and the sampling pipeline cannot control the sampling volume, which easily causes unnecessary waste of the small amount of umbilical cord blood.

detailed description

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

The umbilical cord blood sampling device as shown in Figure 1 mainly includes a blood collection needle 2, a collection bag 11 and a vacuum sampler 13. The needle seat part of the blood collection needle is sealed and connected with the blood collection needle sheath 1, and the blood collection needle sheath 1 covers the blood collection needle 2, so as to prevent the blood collection needle 2 from being polluted. The vacuum sampler 13 is connected to the collection bag 11 through the second conduit 12, and the filling tube 6 is fixedly connected to the collection bag 11, and the blood preservation solution can be injected into the collection bag 11 through the filling tube 6. After the umbilical cord blood collection and sampling device is assembled, the blood preservation solution can be pre-filled into the collection bag 11 through the filling tube 6, and the filling tube 6 is sealed, and then the umbilical cord blood sampling device is sterilized by high pressure steam .

When using the umbilical cord blood sampling device to collect umbilical cord blood, first remove the blood collection needle sheath 1, and then use the blood collection needle 2 to puncture the umbilical cord, and the umbilical cord blood flows into the collection bag 11 through the first catheter 5 due to gravity, and then In the collection bag 11, the inflowing umbilical cord blood is mixed with the blood preservation solution. A liquid stop clip 4 is arranged on the first conduit 5. When collecting umbilical cord blood, the liquid stop clip 4 needs to be opened. After the blood collection is completed, the liquid stop clip 4 on the first conduit 5 is closed to prevent the liquid in the collection bag 11 from flowing back. Then the first conduit 5 is sealed and cut off. After the blood collection is completed, the blood collection needle 2 is in an exposed state, which may cause safety risks such as stab wounds. For this reason, as shown in FIG. The acupuncture protective cover 3 is a hollow cylinder, and the first conduit 5 runs through the anti-acupuncture protective cover 3 and is movably socketed with the anti-acupuncture protective cover 3. Therefore, after the blood collection is completed, directly pull the anti-acupuncture protective cover 3 to make it It moves toward the blood collection needle relative to the first conduit 5 until the anti-needle protection cover 3 is fitted on the outside of the blood collection needle 2, thereby eliminating safety risks such as possible stab wounds caused by the exposed blood collection needle 2.

When sampling is required, a vacuum sampler 13 can be used to conveniently take a sample from the collection bag 11 through the second conduit 12 . In order to facilitate sampling control, as shown in Figure 1, a liquid stop clip 4 can be set on the second conduit 12, and an easy-break joint 8 is arranged between the second conduit 12 and the collection bag 11, and the easy-break joint One end of 8 is airtightly connected to the collection bag 11, and the other end is airtightly connected to the second conduit 12 through the sealing head sheath 7. When sampling is required, directly break the easy-break joint 8, and the liquid in the collection bag 11 can pass through the easy-break joint 8 and then enter the second conduit 12 under the action of the vacuum sampler 13, and then go along the second The conduit 12 flows into the vacuum sampler 13, which can make the sampling operation simpler and more convenient, and the sample volume can be controlled by the vacuum sampler 13, thereby reducing unnecessary waste during cord blood sampling.

During cord blood collection, the collection bag 11 needs to be shaken to prevent coagulation. In order to facilitate the shaking operation of the collection bag 11 by the collection bag shaking device, as shown in Figure 1, two hanging holes 9 can be set on the collection bag 11, and by setting the hanging holes 9, the suspension of the collection bag 11 can be facilitated, so as to be compatible with the collection bag 11. The collection bag shakes the equipment to cooperate. In order to facilitate the observation of the collection volume and sampling volume of umbilical cord blood, as shown in FIG. 1 , a scale mark 10 may be added on the outer surface of the collection bag 11 . The scale marks 10 are several parallel scale lines etched on the outer surface of the collection bag 11, such as laser etching, or several parallel ribs fixedly connected to the outer surface of the collection bag 11 , and, these convex ribs and the collection bag 11 are integrally formed, not only simple in structure, but also low in processing cost.

The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. It should be pointed out that any modification, equivalent replacement and improvement made within the spirit and principles of the utility model, etc., All should be included within the protection scope of the present utility model.
