Description

Self-vaginal uterine cavity autologous blood recovery device

Technical Field

The utility model relates to the field of medical equipment, in particular to an autologous blood recovery device from a vaginal uterine cavity.

Background

Autologous blood recovery refers to a blood transfusion mode in which blood loss (body cavity hematocrit, bleeding during operation, and post-operation blood permeation) of a patient is treated by a blood recovery device through procedures such as filtration, washing, concentration, and the like, and then red blood cells are returned to the patient. And (3) removing most pollutants and coagulation factors from blood through consumable treatment, and obtaining a washed red blood cell product. The autologous transfusion can effectively reduce the dependence on blood inventory, relieve blood tension, avoid various complications after blood transfusion and reduce the influence of blood storage damage on patients; reducing the risk of infusing allogeneic blood; no transfusion reaction; reducing the effect of blood storage injury on the patient; solves the blood supply problem of special blood type (RH-); solves the problem of blood supply of special religious believes who do not receive allogeneic blood transfusion. The method is suitable for the situations of open heart and vascular surgery, total joint replacement surgery, spine surgery, liver transplantation, selective neurosurgery, ectopic pregnancy rupture and the like, so that in the dangerous pre-placenta surgery in obstetrics, the bleeding risk of a puerpera is high due to physiological factors, the situation is urgent, the recovery of the autologous blood in the operation of the puerpera is particularly important, and the recovery of the autologous blood of the puerpera from the incision of the lower abdomen of a patient is carried out in various hospitals at present, so that the effect is good. In the caesarean operation, since the uterine cavity is communicated with the outside through the vagina, blood in the puerperal operation can flow out of the vagina in addition to the operation incision. In the clinical operation, there is a situation that there is not much bleeding in the abdomen during the operation, but a great amount of blood is accumulated under the buttocks of the patient during or after the operation, however, the collected blood cannot be polluted due to the requirement of autologous blood recovery, and the vaginal flow blood cannot be recovered.

The inventor researches find that the existing blood recovery device has at least the following disadvantages:

1. at present, a device for recovering blood from the vaginal end is not available, but the blood recovery from the abdomen alone cannot be used for collecting blood in the operation of a puerpera, so that the blood waste of a patient is caused;

2. even if blood recovery is not carried out, only the calculation and observation of the bleeding amount are carried out, more vaginal bleeding amount measurement is carried out on a blood pad on an operation bed in the prior art, and the blood observation method is neither accurate nor has hysteresis.
