Abstract
The utility model discloses a disposable self-blood recoverer, which comprises a suction head, a blood filter, a blood collection bottle, a final filter, a negative pressure suction bottle, a negative pressure source and the like, and the blood suction in the abdominal cavity of a patient is collected for standby after multi-stage filtration by utilizing the negative pressure principle under the sealing state. The utility model discloses collect and retrieve and filtration processing in an organic whole and automatic synchronization go on, laborsaving saving time, for shortening operation time effectively creates the condition to can overcome and adopt the artifical recovery method of traditional openness to cause blood pollution's disadvantage. The device is suitable for the extrauterine pregnancy operation and the operative treatment of liver, spleen, cardiovascular disease, aneurysm and the like, is particularly suitable for the rescue treatment of hemorrhagic shock patients, and has the advantages of safety, reliability, simple and convenient operation, no complication, no sequela and the like.
Description
This utility model belongs to medical mechanical domain, and particularly a kind of operation is with oneself blood recover.
Ectopic pregnancy is the common acute abdomen of department of obstetrics and gynecology, and especially concurrent hemorrhagic shock patient is badly in need of performing a surgical operation treatment.Usually the Intraabdominal blood of patient must be fed back after treatment to the patient in the operation.To be the patient put in the patient abdominal cavity with noggin to traditional method at present commonly used draws and get blood, and the reuse funnel is put filtered through gauze, feeds back to the patient through vein then.Though this method also can be given the patient with oneself blood recovery of patient, this method is to carry out with manually-operated in open environment fully, exists many disadvantages.At first be that whole process effort is consuming time, have slightly and slowly will miss an opportunity because of a delay even lose the rescue chance, being difficult to simultaneously to avoid the fiber of Pulvis Talci on the glove and Cotton Gossypii gauze to be brought in the blood in removal process pollutes, and it is insufficient to adopt this method to reclaim blood, waste blood increases the weight of financial burden to the patient.
The purpose of this utility model is developed a kind of quick, safe, easy, oneself blood recover reliably exactly.
The purpose of this utility model realizes by following technical proposals: it is standby to utilize principle of negative pressure to collect with the Intraabdominal blood sucking-off of patient and behind multistage filtering under sealing state.Its concrete structure is: its front end blood transfusion flexible pipe of filter that drainage screen is housed has the attraction head in attraction hole to be connected by Connection Block and head, has big draw point and skewer to go into to collect in the blood bottle on the rear end blood transfusion hose end.The small steel needle of exhaust hose lower end also skewer goes into to collect in the blood bottle, and the upper end is by last filter and negative pressure are hose connection eventually, and the negative pressure flexible pipe other end then skewer is gone in the vacuum suction bottle, and the vacuum suction bottle communicates with negative pressure source.In order to raise the efficiency, attract head to go in the outer tube and forms dual-chamber type by interior pipe box, have side opening on the draw point greatly.Work process of the present utility model is such; Start negative pressure source, the air pressure in vacuum suction bottle and the collection blood bottle descends in succession, is communicated with collection blood bottle and the attraction head that is immersed in the pool of blood sucks the blood transfusion flexible pipe with blood through attracting the hole, enters after filtering through filter to collect blood bottle deposit.Dual-chamber type attract clot that the attraction hole of the outer tube of head and interior pipe front end will be bigger delete for twice every, avoid clot to enter and blocking pipe and filter filter mesh.The side opening of big draw point helps blood circulation, and pin hole is blocked and causes obturation when preventing that draw point from penetrating plug.The end last filter at exhaust hose and the hose connection place of negative pressure can be regulated negative pressure effectively, avoids being destroyed because of the excessive visible component of blood that makes of negative pressure in the collection blood bottle.This utility model also adopts the bigger pipeline of internal diameter, not only helps flowing of blood, and can avoid causing because of negative pressure the modification of pipeline effectively.
Disposable oneself the blood recover of this utility model integrates recovery also to carry out automatically synchronously with filtration treatment, time saving and energy saving, reclaim 500 milliliters of blood and just need 3 minutes (reclaim 500 milliliters of blood with traditional method and need 30 minutes at least), create conditions for shortening operating time effectively, then can win the rescue chance the hemorrhagic shock patient.Whole process is all carried out under sterile closed state, overcomes the disadvantage of using traditional method to bring cotton fiber and glove Pulvis Talci into blood easily, reduces the open opportunities for contamination that reclaims filtering blood.Dual-chamber type attracts an exquisite exquisiteness, can stretch into each position, abdominal cavity, and blood is reclaimed thoroughly, saves blood resource, alleviates patient economy burden, and because hemoperitoneum is able to thorough cleaning, makes patient's postoperative rehabilitation smooth.After blood reclaims and finishes, still can continue on for operation suction and use.Disposable oneself the blood recover of this utility model is applicable to the ectopic pregnancy operation, also is applicable to liver, spleen, cardiovascular, aneurysmal rescue simultaneously, and the operation that is particularly useful for the hemorrhagic shock patient is rescued.Use oneself blood of patient to feed back to avoid using his human blood to make the danger that causes the PI infectious disease and various untoward reaction occur in the operation, the negative case of releasable urgent clinical needs particularly special blood group of blood transfusion such as Rh is badly in need of blood transfusion and the predicament of blood source shortage.Through 108 routine clinical practices, prove that this utility model is safe and reliable, easy and simple to handle, no complication, no sequel.During use, should notice that two-chamber attracts head to stretch into the abdominal cavity after, make to attract the hole to be immersed in the pool of blood, to reduce the impact of gas to blood as far as possible; Air pressure in the vacuum suction bottle transfers to 0.01 MPa, and negative pressure is too small, and blood can not inhale, and the excessive visible component that then can destroy blood of negative pressure reduces blood quality; 100 milliliters of blood of every recovery need add 2.5% sodium citrate, 10 milliliters; Also should in time change collection blood bottle, avoid bottle inner blood overfill and be inhaled into the vacuum suction bottle in and (can utilize the unpolluted G/NS liquid empty bottle of just being totally lost to replace collecting the blood bottle in case of necessity).The whole operation process wants strictness to hold the aseptic technique pass, and the blood in the collection blood bottle in time feeds back to patient after disposable transfusion set filters once more.
Below in conjunction with accompanying drawing the technical solution of the utility model is further elaborated.
Fig. 1 is this utility model structure chart.
Fig. 2 attracts header structure figure for this utility model two-chamber.
