Abstract
The utility model discloses a kind of blood exchange transfusion set's interface bundle, comprise blood bag interface and puncture needle interface, the head end inwall of described blood bag interface is provided with female thread, described puncture needle interface comprises can penetrate the puncture portion that blood bag interface stretches into blood bag and the columnar part be connected with puncture portion, described columnar part outer wall is provided with the external screw thread matched with female thread, puncture interface by female thread with externally threaded connect to sealing with blood bag interface be connected.This utility model avoids the high fault rate that puncture portion quick insertion causes, and when blood bag is connected with blood exchange transfusion set, can guarantee the airtight safety of blood transfusion passage.
Description
Technical field
This utility model relates to blood exchange transfusion set's interface bundle.
Technical background
Having to pass through blood exchange transfusion set when hospital transfuses blood could be input in patient body from blood bag blood, the connection of blood exchange transfusion set and blood bag must be airtight, traditional method inserts the interface of blood bag with the puncture needle of blood exchange transfusion set upper end and draws into a passage, nursing staff is in this operating process, the puncture needle of blood exchange transfusion set is easily inserted tiltedly or was inserted deeply and punctured blood bag, thus causes blood contamination, waste or affect the treatment of patient.
Utility model content
Technical problem to be solved in the utility model is just to provide a kind of blood exchange transfusion set's interface bundle, when blood bag is connected with blood exchange transfusion set, can guarantee the airtight safety of blood transfusion passage.
For solving the problems of the technologies described above, this utility model adopts following technical scheme:
Blood exchange transfusion set's interface bundle, comprise blood bag interface and puncture needle interface, the head end inwall of described blood bag interface is provided with female thread, described puncture needle interface comprises can penetrate blood bag interface and the puncture portion stretching into blood bag and the columnar part be connected with puncture portion, described columnar part outer wall is provided with the external screw thread matched with female thread, puncture interface by female thread with externally threaded connect to sealing with blood bag interface be connected.
Preferably, the outer wall of described blood bag interface is provided with at least one piece of the first lug, the outer wall of described columnar part below external screw thread is provided with at least one piece of the second lug.
Preferably, the outer wall in described puncture portion is provided with pin hole, and the inside in puncture portion is provided with the endoporus being communicated with pin hole, and the inside of described columnar part is provided with the interior pipe being communicated with endoporus, and described interior pipe is communicated with blood exchange transfusion set.
Preferably, the shape of described endoporus is truncated cone-shaped, and one end that in endoporus, diameter is less is connected with pin hole, and one end that in endoporus, diameter is larger is connected with interior pipe.
The beneficial effects of the utility model are:
After puncture portion stretches into blood bag interface certain depth, female thread and externally threaded threaded engagement, now, puncture portion needs slowly to screw in blood bag, avoid the high fault rate that puncture portion quick insertion causes, due to the effect be threaded, the puncture portion direction of motion can not be crooked, effectively prevent the sidewall that blood bag interface is pierced through in puncture portion, screw thread has certain length simultaneously, puncture portion can be made after female thread connects completely with external screw thread cannot to continue to go deep into blood bag, thus prevent puncture portion to thrust blood bag to cross dark and puncture blood bag, ensure that the airtight safety of blood transfusion passage.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, this utility model is described further:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is elaborated.
As shown in Figure 1, this utility model comprises blood bag interface 1 and puncture needle interface 2, the head end inwall of described blood bag interface is provided with female thread 101, described puncture needle interface comprises can penetrate blood bag interface and the puncture portion 201 stretching into blood bag 3 and the columnar part 202 be connected with puncture portion, described columnar part outer wall is provided with the external screw thread 2021 matched with female thread, puncture interface by female thread with externally threaded connect to sealing with blood bag interface be connected.The outer wall of described blood bag interface 1 is provided with at least one piece of the first lug 102, the outer wall of described columnar part 202 below external screw thread 2021 is provided with at least one piece of the second lug 203, two handss to pinch the first lug and the second lug respectively and be convenient to carry out female thread and be connected with externally threaded.The outer wall in described puncture portion 201 is provided with pin hole 204, the inside in puncture portion is provided with the endoporus 2041 being communicated with pin hole, the inside of described columnar part 202 is provided with the interior pipe 2022 being communicated with endoporus, described interior pipe is communicated with blood exchange transfusion set, blood in blood bag goes out to enter blood exchange transfusion set by pin hole, endoporus and interior pipe flow successively and transfuses blood to patient, ensure that the airtight safety of blood transfusion passage.The shape of described endoporus 2041 is truncated cone-shaped, and one end that in endoporus, diameter is less is connected with pin hole 204, and one end that in endoporus, diameter is larger is connected with interior pipe 2022, and the shape of truncated cone-shaped increases the blood flow entering pin hole gradually, improves blood transfusion efficiency.
Using method of the present utility model is:
When the practical operation that blood bag interface is connected with puncture needle interface, in order to the leakage of anti-Hemostatic Oral Liquid, first blood bag interface is placed upward, the first lug is pinched with a hands, another hands pinches the second lug, afterwards puncture portion is thrust in blood bag interface from top to bottom, until female thread contacts with external screw thread, rotating the second lug makes puncture needle interface screw in blood bag interface, until female thread and external screw thread are connected closely completely, now, the part in puncture portion stretches in blood bag, blood in blood bag passes through pin hole successively, endoporus and interior pipe flow enter in blood exchange transfusion set, ensure that the airtight safety of blood transfusion passage.
Be described with regard to this utility model preferred embodiment above, but can not be interpreted as it is restriction to claim.This utility model is not only confined to above embodiment, its concrete structure allows to change, those skilled in the art can make various change and distortion according to this utility model, only otherwise depart from spirit of the present utility model, all belong to the scope that this utility model claims define.
