Description
The present invention relates generally to and a kind ofly be used to collect liquid and liquid is failed back intravital equipment of patient and method, relate in particular to a kind of bloodletting instrument that is suitable for autotransfusion.More particularly, the present invention is directed to a kind of bloodletting instrument, make a disposable interior bag that extracts to separate and to be used for failing back with an outer container, continue blood drawing so that another can be extracted in the bag insertion container.
Blood drawing equipment is generally used in the autotransfusion, to extract from the collecting chamber of a thoracic duction instrument and to gather from body homology blood.Autotransfusion refers to being called from body homology blood of patient oneself failed back.Autotransfusion is the best way of failing back, because the blood of carrying is patient's oneself blood, has therefore got rid of the inconsistent problem of blood group and has made blood-borne diseases such as hepatitis, acquired immune deficiency syndrome (AIDS) etc.And the storage blood that provides than a donor from body homology blood is fresher and comprise patient's self antibody.
The autotransfusion of a kind of being called " operation back " is after operation the blood of patient's oneself extraction to be failed back, and wherein the blood collecting of Chou Chuing is also failed back in the patient body.Operation back autotransfusion in use has limitation, because the blood kind that can fail is back had strict regulation.At present, think unique and be applicable to that the postoperative blood of autotransfusion is mediastinum blood, promptly from anatomical cavity in the thoracic cavity or the blood in the chamber.
Current, thoracic duction instrument is often used in the patient's that performs an operation the breast chamber the post-operative care.Thoracic duction instrument uses the pipe link on patient's breast chamber that liquid in the breast chamber and air are discharged, and pipe enters liquid and air in the collecting chamber in the thoracic duction instrument.Thoracic duction instrument is linked on the vacuum source, and vacuum source makes manages in the liquid and air suction collecting chamber that absorbs and will collect from the breast chamber.In case after collecting, use an autotransfusion pump or blood drawing bag blood can be extracted out from collecting chamber.
The use of blood drawing bag is a known technology in the autotransfusion.People's such as Herweck U.S. Patent No. 5 for example, 380,314 disclose a kind of blood sampling bag, have a contained spring, make bag be biased to a solid shape before use and also produce simultaneously a negative pressure therein, with the artificial blood that extracts from the collecting chamber of thoracic duction instrument.But above-mentioned patent No.5, a shortcoming of 380,314 equipment is to use gravity installation just can fail back, wherein bag is suspended near the patient and gravity can be failed back the blood of collecting in the patient body from wrapping to discharge.The suitably drain of the equipment of above-mentioned patent is unless user takes extra step that ambient air is flowed in the blood sampling bag earlier before failing back but unfortunately.This flow step must be carried out forcing the blood that collects in the rigidity blood sampling bag to be discharged, otherwise have only gravity will be in fail back process deficiency so that blood discharge from wrap.
The example of another bloodletting instrument is known in people's such as Gentelia U.S. Patent No. 5,201,703, and it discloses a kind ofly gathers blood and blood is failed back the intravital device of patient from thoracic duction instrument.Above-mentioned patent No.5,201,703 at a kind of equipment self-contained, that can at will use fully, comprises a rigid outer container, wherein includes a flexible bag that is connected as a single entity, and same thoracic duction instrument together uses.Between rigid container and interior flexible bag, apply or keep negative pressure so that be stored in blood in the collecting chamber can the suction bag in.When the blood that extracts through connecting patent No.5, the equipment in 201,703 is during with the pipe of thoracic duction instrument, blood begins to charge into and wraps in flexible.In case after being filled with the blood of aequum in the bag, the interior bag that entire equipment is comprised outer rigid container and be filled with blood from thoracic duction instrument take off and hang over patient with a suitable suspension arrangement near be used for failing the blood that recovery collects.
But No.5, a shortcoming of 201,703 equipment is that entire equipment must all be used in failing back process.Especially all must utilize failing back process China and foreign countries rigid container and interior flexible bag because this equipment is a global design, wherein in flexible bag can not separate with outer rigid container.As a result, just must change entire equipment-a container and an extraction bag in order continuously same patient to be carried out autotransfusion.Correspondingly, owing to all must change entire equipment after each blood transfusion, cost is too high concerning user.
No.5, it is unlikely sometimes that another shortcoming of 201,703 is to use above-mentioned bloodletting instrument to obtain the conventional method of failing back fast.Existingly will extract that bag fixedly is connected on the property container of the outside or be unsuitable for being used for carrying out failing back fast technology by the blood drawing bag that the rigid container design of one is made.For example, as everyone knows fail back fast by producing one in the prior art at the pressure sleeve around flexibility blood drawing bag of on a vesicle of the pressure sleeve of container, exerting pressure.If but evacuation container be rigid design then around the pressure sleeve of container just can not apply enough pressure make in flexible bag depress and produce a high speed and fail back.Because the shortcoming of these costs and performance, need make and have only interior flexible bag to be used for defeated blood back liquid in the bloodletting instrument and the rigid outer container maintenance links to each other further to gather blood from thoracic duction instrument with a vacuum source.
Correspondingly, need before failing back, the interior flexible bag in the bloodletting instrument can separate with outer rigid container, from collecting chamber, further to gather blood so that another flexible bag can be used in the same container.Therefore, also need a bloodletting instrument can provide one cost-effective blood to be failed back the intravital device of patient, use a plurality of removable blood drawing bags to continue blood drawing and fail back simultaneously.
A main purpose of the present invention provides a kind ofly cost-effectively fails back the intravital device of patient with blood.
Another object of the present invention provides a kind of effective method, will fail back in the patient body from body homology blood.
Also purpose of the present invention provides a kind of blood drawing packing and puts, and comprises flexible bag in, can separate with its outer container in failing back process.
A further object of the present invention provides a kind of discerptible extraction bag, is suitable for being installed in a pressure sleeve and is used for producing at a high speed and fails back.
These and other objects of the present invention realize with its a kind of presently preferred embodiment, with exemplary and the indefiniteness mode is described, the present invention relates to a kind of use one bloodletting instrument extracted and failed blood back liquid to a patient equipment and a kind of method, bloodletting instrument be included in the outer rigid container one discerptible in flexible bag, be used for back fail from the blood of the extraction of the collecting chamber extraction of a thoracic duction instrument.Outer rigid container comprises a suction inlet that is connected on the vacuum source, and the spatia that vacuum source is used between rigid container and interior flexible bag applies negative pressure.Remain on the pipe of negative pressure by between bag and collecting chamber, keeping fluid flow in the spatia of container with the blood suction bag in the collecting chamber of thoracic duction instrument in.After the blood drawing bag charges into scheduled volume, interior flexible bag is taken out from outer rigid container, and it is neighbouring with the defeated blood that reclaims collection to hang over patient.
