Description

A bone marrow filtration and infusion device

technical field

The utility model relates to a bone marrow filtration and infusion device.

Background technique

The current bone marrow collection is to extract the bone marrow through a needle connected to the syringe, and then insert it into the bone marrow bag with a steel needle. When it is imported into the human body, it is inserted into the bone marrow storage bag with a blood transfusion device, and then exported to the human body. Since the input and output from the bone marrow bag are punctured and filtered with steel needles, if the operation is not done properly, it is easy to cause waste of bone marrow, or needle stick injuries and other problems.

Contents of the invention

In order to solve the problems existing in the current bone marrow collection and injection device, the utility model provides an easy-to-use bone marrow filtration and infusion device.

In order to realize above-mentioned technical purpose, the technical solution of the present utility model is,

A bone marrow filtration and infusion device, comprising a bone marrow storage bag, a filter, a bone marrow inlet and a bone marrow outlet are respectively arranged on the bone marrow storage bag, the bone marrow inlet and the bone marrow outlet are respectively connected with an input pipeline and an output pipeline, the input pipeline and the Filters for filtering fat particles are respectively arranged on the output pipes.

In the bone marrow filtration and infusion device, the input pipeline and the output pipeline are connected to the bone marrow storage bag through a sealed connection tube.

In the bone marrow filtration and infusion device, the bone marrow storage bag is marked with a measuring scale.

In the aforementioned bone marrow filtration and infusion device, the port of the input pipeline is provided with a threaded connection port for connecting with an indwelling needle.

In the aforementioned bone marrow filtration and infusion device, the input pipeline is also connected with a physiological saline input tube.

The bone marrow filtration and infusion device described above has a valve on the saline input pipe.

In the aforementioned bone marrow filtration and infusion device, the output pipeline is provided with two sequentially connected filters.

The technical effect of the utility model is that the airtight connection tube is used for input and output, which avoids needle puncture and avoids bone marrow waste or needle stick injury that may be caused by improper operation. The fat particles in the bone marrow are filtered by setting multiple filters, and the work efficiency is effectively improved through the integrated design of infusion and injection. The scale on the bone marrow bag can accurately measure the amount of bone marrow, and the screw connection on the input tube can The connection is guaranteed to be firm and convenient, and the physiological saline pipeline can be used for flushing. The utility model has a simple structure and can effectively improve work efficiency.

Below in conjunction with accompanying drawing, the utility model is further described.

Among them, 1 is the bone marrow storage bag, 2 is the filter, 3 is the input pipe, 4 is the output pipe, 5 is the measurement scale, 6 is the threaded connection port, 7 is the saline input pipe, 8 is the valve, and 9 is the airtight connection pipe .

detailed description

Referring to Fig. 1, the utility model comprises a bone marrow storage bag, a filter, and a bone marrow storage bag respectively provided with a bone marrow inlet and a bone marrow outlet, the bone marrow inlet and the bone marrow outlet are respectively connected with an input pipeline and an output pipeline, and the input pipeline and the output pipeline are respectively provided with There are filters for filtering out fat particles. In this way, the process of bone marrow collection and injection can be performed through the same device, which effectively improves work efficiency. At the same time, the filter can filter out fat particles to ensure the purity of bone marrow.

The input pipe and the output pipe are connected to the bone marrow storage bag through the airtight connection tube, and the structure of the airtight connection pipe is the same as that of the infusion set before and after the muffi’s drop, so that the input pipe and the output pipe can be connected through this airtight connection pipe, avoiding the previous The problem of using the diameter of the needle to puncture the bone marrow bag is to ensure the sealing effect at the same time, so that the bone marrow is preserved safely and does not leak.

In order to accurately grasp the amount of bone marrow, the bone marrow storage bag is marked with a measurement scale, which can be used to understand the current amount of bone marrow.

In order to facilitate the connection and ensure the sealing effect of the connection, the port of the input pipe is provided with a threaded connection port.

In order to facilitate flushing, a physiological saline input tube is also connected to the input pipeline, through which the device can be cleaned and flushed.

In order to control the amount of physiological saline input and seal, the physiological saline input pipe is provided with a valve.

In order to ensure the filtering effect, there are two filters connected in sequence on the output pipeline.
