Description
Technical Field
The utility model belongs to the field of medical equipment, concretely relates to blood transfusion device with prevent puncturing function.
Background
Venous transfusion is a method of transfusing whole blood or blood components such as plasma, red blood cells, white blood cells or platelets intravenously into the body. Blood transfusion is one of the important measures for emergency treatment and disease treatment, and is widely applied clinically. When the transfusion device is used, a blood transfusion bag or a blood transfusion bottle is hung on a bracket, a needle head on the blood transfusion tube penetrates through an opening of the blood transfusion bag or the blood transfusion bottle to realize the communication between the blood transfusion tube and a blood transfusion bag, and blood enters the blood transfusion tube through the blood transfusion bag or the blood transfusion bottle under the action of atmospheric pressure to realize the blood transfusion to a human body.
The blood transfusion bag is usually used under the condition of rescuing patients in time of overtime, so when the needle head is inserted into the bag body, the insertion speed is high, but because the passing space of the needle head at the interface seat of the blood transfusion bag is small, the material of the bag body has the characteristics of softness and easy change, when the needle point of the needle head is quickly pushed into the bag body from the interface seat, the needle point part can easily pass through the interface seat of the bag body to be contacted with the single-layer side wall of the bag body, and the needle point part can easily puncture the blood transfusion bag, thereby causing the leakage of the blood transfusion bag; when the blood in the bag body leaks, the blood can be polluted by the outside and cannot be reused.
SUMMERY OF THE UTILITY MODEL
The utility model discloses it is anticipated to provide the blood transfusion device who has the puncture-proof function to the individual layer lateral wall department of preventing the bag body is punctured.
In order to achieve the above object, the basic scheme of the present invention is as follows: the blood transfusion device with the puncture-preventing function comprises a bag body, an interface seat and a hard insertion tube, wherein the interface seat and the bag body are integrally formed, the insertion tube is coaxially and fixedly arranged in the interface seat, one end, close to the center of the bag body, of the insertion tube is located outside the interface seat, and one end, close to the center of the bag body, of the insertion tube covers a needle point.
The principle and advantages of the basic scheme are as follows: when the needle head on the blood transfusion tube is inserted into the interface seat, the needle head and the needle point move along the hard cannula, and after the needle head is locked in the interface seat, the bag body is communicated with the blood transfusion tube; at the moment, the needle point is continuously positioned in the intubation tube, and the intubation tube can limit the needle point, so that the situation that the needle point is shifted to the bag body to puncture the bag body is avoided; meanwhile, the cannula can guide the movement of the needle.
Furthermore, the outer wall of the interface seat is provided with a plurality of round tables with the diameters increasing in sequence, and the round tables and the interface seat are integrally formed.
When the bag body and the blood transfusion tube are communicated, the hand of medical staff can stably hold the round platform, so that the needle head can be conveniently inserted into the interface seat, and meanwhile, the round platform can prevent the interface seat from being punctured.
Furthermore, a first annular block is arranged at the joint of the blood transfusion tube and the needle head, and a thread section in threaded connection with the inner wall of the first annular block is arranged on the inner wall of one end, far away from the insertion tube, of the interface seat.
When the first annular block is pushed to the threaded section, the threads on the outer wall of the first annular block are meshed with the threaded section, and the needle head and the blood delivery tube are screwed into the interface seat, so that the speed of pushing the needle tip into the bag body can be reduced, and the risk of puncturing the bag body is further reduced; meanwhile, the needle head and the blood transfusion tube can be tightly arranged on the bag body due to the arrangement of the thread section, and the needle head and the blood transfusion tube are prevented from falling off from the bag body.
Furthermore, one end of the thread section, which is close to the insertion pipe, is provided with a second annular block which is abutted against the first annular block, and the second annular block is fixedly connected with the inner wall of the interface seat.
When first cyclic annular piece rotated to the screw thread section and was close to the one end of intubate, first cyclic annular piece can offset with the cyclic annular piece of second, can carry out the locking to first cyclic annular piece, and then can carry out the locking to the position of needle point, avoids needle point department and the lateral wall of the bag body to offset.
Furthermore, a first hanging opening is formed in one side, far away from the interface seat, of the bag body.
When in blood transfusion, the transfusion bag can be hung on the bracket through the first hanging port.
Furthermore, one side of the bag body close to the interface seat is provided with two second hanging openings.
When the medical staff disposes the blood in the bags, the medical staff can hang the bags on the bracket through the two second hanging openings, so that the bags can be conveniently driven to move; when the blood bag moves, the interface seat on the bag body faces upwards, and the pressure of blood on the interface seat can be reduced.
Further, two second string of mouthful are followed the vertical axis symmetry setting of interface seat.
When the bag body is hung on the support through the second hanging openings, the stress at the two second hanging openings of the bag body is uniform, and the stress at the joint of the interface seat and the bag body is uniform.
Further, a first sealing rubber is arranged on the inner wall of the second annular block.
When the needle point passes through the first sealing rubber, the bag body and the blood transfusion tube can be communicated, and the first sealing rubber can be tightly attached to the outer wall of the needle head, so that the blood is sealed.
Furthermore, a liquid inlet hole is arranged on the side wall of one end of the insertion pipe close to the center of the bag body.
When the blood transfusion is about to end, partial blood can flow to the bottom of the bag body, and the blood that is located intubate upper end both sides can enter into the intubate through the feed liquor hole this moment, is convenient for lie in the blood of bag body bottom and exports from the needle point, can effectual reduction blood's waste volume.
Further, a second sealing rubber is arranged on the inner wall of the insertion pipe and is fixedly connected with the inner wall of the insertion pipe; the second sealing rubber is positioned between the liquid inlet hole and the interface seat.
Because the second sealing rubber is located between feed liquor hole and the interface seat, second sealing rubber is compared in first sealing rubber this moment, and second sealing rubber is more close to the intubate and is close to the one end at bag body center, and the blood that persists between the one end that second sealing rubber and intubate are close to bag body center is still less, more can reduce the waste of blood.
