Abstract
The utility model relates to medical equipment used for blood recovery in the process of operations, particularly a disposable cell recovering and washing device. The utility model comprises an antifreezing machine, a negative pressure suction machine, a defoaming filter, a washer, etc., wherein, a negative pressure protective chamber is arranged above the defoaming filter. The upper part of the protective chamber is provided with automatic regulating valves with negative pressure. The automatic regulating valves with negative pressure are respectively connected with the antifreezing machine and the negative pressure suction machine through pipelines. The funnel-shaped bottom of each automatic regulating valve with negative pressure is provided with a one-way movable plate, and the lower part of the defoaming filter is communicated with the washer. The utility model can extract effective ingredients after blood in an operating field is recovered once, and the effective ingredients can be input back to patients in time.
Description
This utility model relates to and is used for the medical apparatus and instruments that operation process blood reclaims, and particularly a kind of disposable erythrocyte reclaims wash mill.
In the prior art, the wild blood of surgical operation art generally absorbs the back with cotton wool or suction pump and together falls as garbage disposal with dirt, what have also sucks in the bottle with suction pump, recycle again by reclaimer then, the former has wasted the recycling chance of blood, there is the untimely problem that easily causes blood contamination and useful component loss of recycling in the latter, particularly can not in time give patient with the useful component direct feedback in the blood.
The purpose of this utility model is exactly in order to overcome above-mentioned weak point of the prior art, and carry out the extraction of effective ingredient again after providing that a kind of energy is disposable operating field blood being reclaimed, and the disposable erythrocyte that can in time this effective ingredient be fed back to patient reclaims wash mill.
The purpose of this utility model is achieved in that it comprises anticoagulant device, vacuum extractor, the parts such as bubble filter, scrubber of dispelling; the bubble filter top of dispelling is provided with negative pressure protection chamber; the negative pressure automatic regulating valve is equipped with on this top, protection chamber; and be connected with vacuum extractor with the anticoagulant device respectively by pipeline; its funnel-shaped bottom portion is equipped with unidirectional trap, and bubble filter bottom and scrubber UNICOM dispel.
This utility model compared with prior art can disposablely be finished the recovery of operating field blood, anticoagulant, the bubble of dispelling, filtration and washing process, but also has the negative pressure automatic safety device, to reduce erythrocytic destruction.Blood effective ingredient after this utility model is handled can feed back in time to patient, not only helps patient's the treatment and the recovery of health, and can also reduce patient's expense expenditure.
Fig. 1 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples in detail this utility model is described in detail.
This utility model embodiment by suction chew 1, anticoagulant device 2, anticoagulant input bottle 3, negative pressure protection chamber 4, negative pressure automatic regulating valve 5, vacuum extractor 6, unidirectional portable plate 7, dispel bubble filter 8, drainage screen 9, scrubber 10, centrifuge 11 etc. form; negative pressure protection chamber 4 is arranged on the top of the bubble filter 8 of dispelling; negative pressure automatic regulating valve 5 is equipped with on its top; and be connected with vacuum extractor 6 with anticoagulant device 2 respectively by pipeline; its funnel-shaped bottom portion is equipped with unidirectional trap 7; trap 7 is opened automatically when blood injects, otherwise trap 7 is closed.Dispel and steep filter 8 bottoms and scrubber 10 UNICOMs, the bubble filter 8 of dispelling is improved cardiotomy suction reflux, and the aperture of its filter screen 9 is 40 μ.Centrifugal precipitation separation device is set in the scrubber 10.
Blood recovery of the present utility model is chewed 1 by suction and is attracted blood to anticoagulant device 2 to finish, directly mix and reach blood anticoagulant at anticoagulant device 2 inner bloods with anticoagulant from anticoagulant input bottles 3, the bubble of dispelling is to be finished by the silicone oil that spreads upon in the filter 8, filters and is then finished by filter screen 9.Whole washing is to be finished by flushing, centrifugal, precipitation flushing again, centrifugal, precipitation repetitive process, and wherein centrifugal, depositing technology is finished by the centrifugal separators 11 in the scrubber 10.Negative pressure automatic regulating valve 5 can guarantee that negative pressure protection chamber 4 negative pressure are constant, to reduce hematoclasis.
