Technical Field
The utility model relates to the field of medical technology, concretely relates to hemopoietic stem cell feedback device.
Background
The existing passage for infusing the hematopoietic stem cells clinically is generally a blood transfusion device which has a filtering function, when the hematopoietic stem cells are returned, a part of the hematopoietic stem cells can be lost due to filtering, the clinical effect is weakened, when the number of the returned hematopoietic stem cells is large, the passage is easy to block, the blood transfusion device needs to be replaced, the hematopoietic stem cells are wasted, a lot of inconvenience is brought to clinical work, the workload of nurses is increased, and medical disputes are easy to occur. The requirement of hematopoietic stem cell reinfusion on the infusion speed is very high, the connection port of the blood transfusion device and the patient is slightly small, the reinfusion speed cannot be met, the connector of the blood transfusion device and the PICC catheter of the patient is inserted and not firmly fixed, and the connector is very easy to disconnect along with the activity of the patient and the friction of clothes, so that the hematopoietic stem cells overflow.
SUMMERY OF THE UTILITY MODEL
For solving prior art's problem, the utility model provides a hemopoietic stem cell feedback device reforms transform current medical equipment, plays the problem that improves clinical effect, improves clinical security and reduce medical risk, reduction nursing staff work load.
The purpose of the utility model is realized through the following technical scheme: a hemopoietic stem cell return device is an infusion device and comprises a bottle stopper puncture outfit, a Murphy's dropper, a flow regulator and a connector which are sequentially connected through an infusion tube, wherein one side of the bottle stopper puncture outfit is provided with an exhaust pipe communicated with the infusion tube;
one end of the connecting port is communicated with the infusion tube, the other end of the connecting port is communicated with the PICC catheter, and the connecting port is in threaded connection with the PICC catheter;
the pipe diameter of the connecting port is equal to that of the infusion tube.
The Murphy's dropper is used for: 1) leading the liquid medicine to enter; 2) storing the liquid medicine; 3) observing the flow rate of the liquid medicine; 4) the liquid level and the remaining amount of the liquid were observed.
The flow regulator is used for conveniently regulating the flow velocity of the hematopoietic stem cells.
The utility model discloses the connector of the part that the feedback device is connected with the patient, the pipe diameter is thicker, can satisfy the requirement to speed when hemopoietic stem cell feedback completely.
Furthermore, an exhaust filter screen is arranged at the opening end of the exhaust pipe.
Furthermore, the connecting port is provided with a sealing cap, and the connecting port is in threaded connection with the sealing cap.
Furthermore, one end of the bottle stopper puncture outfit is communicated with the infusion tube, the other end of the bottle stopper puncture outfit is communicated with the infusion bag or the infusion bottle, and the hematopoietic stem cells are arranged inside the infusion bag or the infusion bottle.
The utility model has the advantages that: when the existing passage is used for reinfusing the hematopoietic stem cells, the hematopoietic stem cells are lost every time, the treatment effect is weakened, when the reinfused stem cells are more, the passage is easy to block, the blood transfusion device needs to be replaced, the hematopoietic stem cells are wasted, and a lot of inconvenience is brought to clinical work. Because the requirement of the hematopoietic stem cell reinfusion on the transfusion speed is very high, the connection port of the blood transfusion device and the patient is slightly small, and the reinfusion speed cannot be met. The utility model discloses a to current medical instrument's transformation, the filter screen in the passageway maofei's burette has been removed, the unnecessary loss of hematopoietic stem cell has been avoided, the speed of infusion has been improved, the treatment effect has been improved greatly, the pipe diameter of passageway has still been increased with the patient connector, the demand of clinical quick infusion hematopoietic stem cell has been satisfied completely, and the interface of being connected with patient PICC is threaded, it is fixed safe, can effectively prevent pipeline and patient infusion end because the disconnection that external force caused.
