Description
Technical Field
The utility model belongs to the field of medical equipment, concretely relates to prevent puncturing blood transfusion bag.
Background
The blood transfusion bag is a common medical article, and is a treatment means for rescuing patients for blood transfusion of patients.
In the actual operation process, in order to avoid blood leakage, a larger force is usually needed to puncture the sealing film instantly, but because the two films at the sealing part below the bag body are closer, the bag body film near the liquid outlet pipe is often punctured when the plug of the blood transfusion device enters the bag body, blood leakage is caused, blood is wasted, rescue time is delayed, and doctor-patient disputes are easily caused.
Chinese patent with publication number CN 209122891U discloses a prevent puncturing blood transfusion bag, including the bag body, bag body one end is equipped with the blood sampling pipe the same rather than inside at least, be equipped with a sleeve pipe in the blood sampling pipe, be equipped with spacing snap ring and lower spacing snap ring in the blood sampling pipe, the sleeve pipe is last spacing snap ring and lower spacing snap ring between the activity setting, the sleeve pipe is kept away from the one end of lower spacing snap ring and is equipped with the second shutoff layer. The device passes through the sleeve pipe and slides in the twinkling of an eye to the bag body, forms the protective layer at syringe needle position, avoids the syringe needle to impale the bag body, but on the one hand the device structure is comparatively complicated, increases manufacturing cost, and on the other hand, because the drain pipe structural change, correspondingly, the syringe needle also need match the drain pipe just can the blood transfusion smoothly, and the syringe needle before causing is extravagant.
SUMMERY OF THE UTILITY MODEL
The utility model discloses the problem that will solve is: the utility model provides a prevent puncturing blood transfusion bag, solve and lack the protection transition between the blood transfusion bag drain pipe that uses at present and the bag body, cause the blood transfusion ware plug to puncture bag body film, arouse the problem of blood leakage.
The utility model adopts the technical proposal that:
a puncture-proof blood transfusion bag comprises a bag body and a liquid outlet pipe arranged at the bottom of the bag body, wherein a sleeve is arranged at the top end of the liquid outlet pipe in the bag body, the diameter of the sleeve is the same as that of the liquid outlet pipe, and a plug of a blood transfusion device penetrates through a sealing film and then is arranged in the sleeve; the blood transfusion device plug is prevented from directly puncturing the bag body film.
Furthermore, the wall surface of the sleeve is provided with through holes which correspond to the filtering holes of the blood transfusion device plug one by one; the blood transfusion device is convenient for blood to flow in, so that blood residue is avoided, and waste is avoided.
Furthermore, the length of the sleeve is 1-2cm, so that the plug of the blood transfusion device is protected, and the influence of overlong blood transfusion in the bag body is avoided.
Furthermore, two layers of sealing films are arranged in the liquid outlet pipe and comprise a first sealing film and a second sealing film, the first sealing film is arranged at the top end of the liquid outlet pipe and used for sealing the bag body and the liquid outlet pipe, and the second sealing film is positioned at the lower part of the liquid outlet pipe; double-layer protection is formed to avoid blood leakage.
Further, the first sealing film is a medical rubber film; has good sealing effect and is convenient for the blood transfusion device plug to pass through.
Further, the second closing film is of a one-way valve structure; the plug of the blood transfusion device moves towards the bag body, and the blood leakage caused by the loose and downward movement of the plug of the blood transfusion device is avoided.
Furthermore, a hanging hole is formed in the middle of the top end of the bag body and used for hanging the bag body.
Compared with the prior art, the beneficial effects of the utility model are that:
1) the puncture-proof blood transfusion bag has the advantages that the sleeve is arranged in the bag body along the extension of the liquid outlet pipe, and plays a role in guiding and limiting the blood transfusion device plug which penetrates out of the liquid outlet pipe in the bag body, so that the bag body is prevented from being in direct contact with the blood transfusion device plug, and the film of the bag body is protected from being punctured;
2) the sleeve is provided with a through hole corresponding to the filtering hole of the transfusion device plug, and the through hole is superposed with the filtering hole, so that blood output is facilitated, and waste caused by blood residue is avoided;
3) two layers of sealing films are arranged in the liquid outlet pipe, the first sealing film is mainly used for sealing the bag body, and the second sealing film is used for fixedly clamping the plug of the blood transfusion device, so that the plug of the blood transfusion device is prevented from loosening and falling to cause blood leakage;
4) simple structure, use original blood transfusion ware plug can to the use flow is the same with original flow, the operation of being convenient for.
