3results about How to "Avoid blood loss" patented technology

The extension device comprises a dialysis remaining needle connecting pipe, one end of the dialysis remaining needle connecting pipe is connected with one end of a hard pipe in a sealed mode, and the other end of the hard pipe is connected with one end of a second extension pipe hose in a sealed mode. A clamping and closing device for closing or opening a passage in the second extension tube hose is arranged on the outer side of the second extension tube hose, and a silica gel blood sampling opening is formed in the middle of one side of the hard tube. The remaining needle for dialysis is easy to operate, the remaining needle for dialysis is lengthened, the clamping function is added, blood loss of a patient in nursing operation is effectively avoided, the silica gel blood sampling opening is additionally arranged, blood sampling of the patient is facilitated, and the two hands of medical staff are prevented from being polluted by the blood of the patient.

The utility model provides a kind of infusion blood sampling device.In the utility model, after the central venous blood of critical patient is extracted using blood collector, the mixture in syringe is injected into the central vein of critical patient via central venous catheter, so that iatrogenic blood loss can be avoided.After blood sampling, new infusion bottle, new infusion tube and new pump do not need to be used, drug and instrument waste are avoided, and drug and instrument costs are reduced.When the infusion blood sampling device leaves factory, the nipple in the needle cylinder in the syringe is integrally formed with the first catheter and cannot be detached, so that the syringe is not pulled off from the first catheter, and the nipple in the needle cylinder in the syringe is always isolated from the outside and not exposed to the outside, so that external pollutants can be prevented from being injected into the central vein of critical patient, and health and safety threat to critical patient can be avoided.

The utility model belongs to the technical field of medical auxiliary instruments, and discloses a sandbag compression fixing belt device which comprises a fixing bag body, the fixing bag body comprises an outer side fixing layer and an inner side fixing layer, the right ends of the outer side fixing layer and the inner side fixing layer are fixedly connected, and the left ends of the outer side fixing layer and the inner side fixing layer are connected through a first hook-and-loop fastener face A and a first hook-and-loop fastener face B; the bottom ends of the outer side fixing layer and the outer side fixing layer are connected through a second hook-and-loop fastener face A and a second hook-and-loop fastener face B. A sliding groove is formed in the upper end of the outer side fixing layer and slidably connected with a waist fixing belt, and the tightness of the waist fixing belt is adjusted through a fastening mechanism. The leg fixing belt is matched and fixed with the third magic tape surface B through the third magic tape surface A; the problems that in the prior art, after herniorrhaphy, a sandbag is placed in the groin and is prone to slipping off, the working intensity of medical staff is increased, and wound recovery of a patient is not facilitated are solved.
