Description
Technical Field
The utility model relates to the technical field of medical treatment, specifically a double-end blood transfusion device.
Background
In hospital clinical work, there are often patients who need to transfuse blood, and more than one bag of blood is transfused. The two bags of blood need to be separated by physiological saline in the process of transfusion, which is to prevent the two bags of blood with different blood sources from causing coagulation reaction. In the existing single-tube blood transfusion device, only one puncture needle is arranged at the top end of a transfusion tube, and the puncture device needs to be pulled and inserted back and forth to respectively connect a physiological saline bag or a blood bag, so that the operation is very complicated, and the phenomenon that residual blood enters the physiological saline and the coagulation reaction is possibly caused cannot be avoided. In order to avoid the situations, a Y-shaped blood transfusion device is commonly used for blood transfusion at present, the Y-shaped blood transfusion device comprises two puncture needles, the two puncture needles are respectively connected into a physiological saline bag and a blood bag, and a medical Y-shaped joint is used for communicating a blood transfusion tube with a transfusion tube. However, the puncture needle is connected into the blood bag, so that the blood bag is often punctured, the waste of blood products is increased, and the risk of blood transfusion is increased.
In view of the above-mentioned shortcomings in the prior art, it is urgently needed to design a double-head blood transfusion device, which avoids puncturing the blood bag, reduces the waste of blood products, and reduces the risk of blood transfusion.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough of prior art, provide a double-end blood transfusion ware.
In order to realize the purpose of the utility model, the utility model adopts the following technical scheme:
a double-end blood transfusion device is characterized in that: including first pipe 1, the one end of first pipe 1 is connected with vein puncture needle 2, the other end of first pipe 1 is connected with second pipe 4 through drip chamber 3, the other end of second pipe 4 is connected with blood transfusion tube 6 and transfer line 7 through three way connection 5, the other end of blood transfusion tube 6 is connected with blood transfusion puncture needle 10, the other end of transfer line 7 is connected with infusion puncture needle 12, install first flow regulator 8 on the blood transfusion tube 6, install second flow regulator 9 on the transfer line 7.
The free end of the blood transfusion puncture needle 10 is an oval blind end, and a plurality of blood inlet holes 11 are arranged on the side wall of the blood transfusion puncture needle 10 in a staggered mode.
A filter screen is arranged in the dropping funnel 3.
The beneficial effects of the utility model reside in that: the oval end blood transfusion puncture needle 10 avoids puncturing the blood bag, reduces blood product waste, and reduces blood transfusion risk.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Shown in the figure: the blood transfusion system comprises a first catheter 1, a vein puncture needle 2, a dropping funnel 3, a second catheter 4, a three-way joint 5, a blood transfusion tube 6, a transfusion tube 7, a first flow regulator 8, a second flow regulator 9, a blood transfusion puncture needle 10, a blood inlet 11 and a blood transfusion puncture needle 12.

Example 1:
a double-head blood transfusion device, as shown in fig. 1, characterized in that: including first pipe 1, the one end of first pipe 1 is connected with vein pjncture needle 2, the other end of first pipe 1 is connected with second pipe 4 through dropping funnel 3, the other end of second pipe 4 is connected with blood transfusion tube 6 and transfer line 7 through three way connection 5, the other end of blood transfusion tube 6 is connected with blood transfusion pjncture needle 10, the other end of transfer line 7 is connected with infusion pjncture needle 12.
The free end of the blood transfusion puncture needle 10 is an oval blind end, and a plurality of blood inlet holes 11 are arranged on the side wall of the blood transfusion puncture needle 10 in a staggered mode.
The blood transfusion tube 6 is provided with a first flow regulator 8, and the transfusion tube 7 is provided with a second flow regulator 9.
A filter screen is arranged in the dropping funnel 3.
The utility model discloses a working process does: after the blood bag is opened, the blood transfusion puncture needle 10 of the oval end is inserted, and the blood transfusion puncture needle 10 of the oval end does not puncture the blood bag.
In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention. Moreover, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit and the scope of the invention.
