A device for alleviating complications after hematopoietic stem cell transplantation

Abstract

The invention relates to the technical field of hematopoietic stem cell transplantation, and discloses a device for alleviating complications after hematopoietic stem cell transplantation, comprising a casing, a speed regulating mechanism is fixedly connected to the right side of the casing, and an air suction fan is plugged inside the casing , the inside of the shell is fixedly connected with a winding mechanism, the inside of the shell is plugged with a gear rod, the outer side of the gear rod is meshed with a reel, and the front of the reel is fixedly connected with a filter element, the reel The top of the reel is fixedly connected with a reset rope, and the bottom of the reel is fixedly connected with a roll rope. The device for relieving complications after hematopoietic stem cell transplantation drives the flywheel to rotate through the rotation of the driving shaft, the flywheel drives the gear to rotate, the gear drives the driven shaft to rotate, the driven shaft drives the transmission shaft to rotate, and the transmission shaft drives the suction fan through the transmission belt Rotate, and then through the cooperative use of suction fan and baffle net, thereby reached the effect that can improve user's breathing quality.

Description

technical field [0001] The invention relates to the technical field of hematopoietic stem cell transplantation, in particular to a device for alleviating complications after hematopoietic stem cell transplantation. Background technique [0002] Hematopoietic stem cell transplantation refers to the removal of tumor cells or abnormal cloned cells in the recipient after pretreatment with high-dose radiotherapy and chemotherapy or other immunosuppressants, blocking the pathogenesis, and then transplanting autologous or allogeneic hematopoietic stem cells to the recipient to make the recipient It is a therapeutic means to rebuild the blood building and immunity of the patient to achieve the purpose of treatment. [0003] After hematopoietic stem cell transplantation, patients are prone to be infected by various bacteria, among which the lungs are most susceptible to bacterial infection. In order to reduce postoperative complications, patients need to wear respiratory protection d...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a device for alleviating complications after hematopoietic stem cell transplantation, which has the advantages of being able to automatically adjust the filtration intensity according to the air quality, has good protection effect, can improve the breathing quality of the user, and relieve complications, etc., and solves the problem of The existing masks have a relatively simple isolation effect on bacteria, cannot adjust the filtering effect according to the external environment, and the protection is not comprehensive enough. Due to the poor physical condition of the postoperative patient, the mask will also affect the normal breathing of the patient and cause discomfort for the patient.
