Abstract
A kind of anti-Joint's falling off transfusion device, comprise transfusion device or blood exchange transfusion set, puncture needle or connection tube and snap close (5), there is a plug (31) lower end (3) of transfusion device or blood exchange transfusion set, there is a socket (41) upper end (4) of puncture needle or connection tube, the inwall of snap close has screw thread (51), the flange collar (52) having a circle inwardly to plough under suitable for reading, the flange (32) that the top of the plug (31) of the lower end of transfusion device or blood exchange transfusion set has a circle outwardly, snap close is enclosed within outside the lower end of transfusion device or blood exchange transfusion set, the internal diameter of the flange collar on snap close is greater than the external diameter on the top of plug and is less than the external diameter of flange, the upper edge of the socket of the upper end of puncture needle or connection tube has a circle external screw thread (42).After plug and socket being plugged together, screwed by snap close on the external screw thread of the upper edge of socket, the flange collar on snap close catches on the flange on the top of plug, effectively can prevent the splice failure of transfusion device or blood exchange transfusion set and puncture needle or connection tube.
Description
Technical field
This utility model relates to a kind of medical apparatus, a kind of anti-Joint's falling off transfusion device.
Background technology
As shown in Figure 1, common infusion set comprises transfusion device or blood exchange transfusion set and puncture needle or connection tube, there is the plug 11 of a hollow lower end 1 of transfusion device or blood exchange transfusion set, there is a socket 21 upper end 2 of puncture needle or connection tube, plug 11 is inserted in socket 21, relies on the frictional force of mating surface to make both link together., usually can there is the accident that transfusion device or blood exchange transfusion set throw off with puncture needle or connection tube, gently then pollute, just in fluid waste, the blood vessel outflow of infusion in this structure, heavy then air embolism occurs in liquid infusion process.
Summary of the invention
This utility model is intended to propose a kind of infusion set that can prevent the splice failure of transfusion device or blood exchange transfusion set and puncture needle or connection tube, a kind of anti-Joint's falling off transfusion device.
This anti-Joint's falling off transfusion device comprises transfusion device or blood exchange transfusion set and puncture needle or connection tube, there is the plug of a hollow lower end of transfusion device or blood exchange transfusion set, the upper end of puncture needle or connection tube have the plug of the lower end of an energy and transfusion device or blood exchange transfusion set plug together mutually together with socket.This anti-Joint's falling off transfusion device also comprises the snap close of a tubular, and the inwall of snap close has screw thread, the flange collar having a circle inwardly to plough under suitable for reading of snap close.The flange that the top of the plug of the lower end of transfusion device or blood exchange transfusion set has a circle outwardly; Snap close is enclosed within outside the lower end of transfusion device or blood exchange transfusion set, and the flange collar on snap close is positioned at the top of the flange on the top of plug, and the internal diameter of snap close is greater than the external diameter of flange, and the internal diameter of the flange collar on snap close is greater than the external diameter of plug and is less than the external diameter of flange.The external screw thread that the upper edge of the socket of the upper end of puncture needle or connection tube has a circle to match with the screw thread of the inwall of snap close.
When this anti-Joint's falling off transfusion device uses, after transfusion device or the plug of lower end of blood exchange transfusion set and the socket of the upper end of puncture needle or connection tube are plugged together, snap close is screwed on the external screw thread of the upper edge of the socket of the upper end of puncture needle or connection tube, snap close suitable for reading on flange collar catch on the flange on the top of the plug of transfusion device or blood exchange transfusion set, effectively can prevent the splice failure of transfusion device or blood exchange transfusion set and puncture needle or connection tube.
Accompanying drawing explanation
Fig. 1 is the structure chart of existing common infusion set;
Fig. 2 is the structure chart of anti-Joint's falling off transfusion device;
Fig. 3 is the application drawing of anti-Joint's falling off transfusion device.
Detailed description of the invention
As shown in Figure 2, this anti-Joint's falling off transfusion device comprises transfusion device or blood exchange transfusion set and puncture needle or connection tube.There is the plug 31 of a hollow lower end 3 of transfusion device or blood exchange transfusion set; The upper end 4 of puncture needle or connection tube have the plug 31 of the lower end 3 of an energy and transfusion device or blood exchange transfusion set plug together mutually together with socket 41.This anti-Joint's falling off transfusion device also comprises the snap close 5 of a tubular, and the inwall of snap close 5 has screw thread 51, the flange collar 52 having a circle inwardly to plough under suitable for reading of snap close 5; The flange 32 that the top of the plug 31 of the lower end of transfusion device or blood exchange transfusion set has a circle outwardly, snap close 5 is enclosed within outside the lower end 3 of transfusion device or blood exchange transfusion set, flange collar 52 on snap close 5 is positioned at the top of the flange 32 on the top of plug 31, the internal diameter of snap close 5 is greater than the external diameter of flange 32, and the internal diameter of the flange collar 52 of inwardly ploughing under on snap close 5 is greater than the external diameter of plug 31 and is less than the external diameter of flange 32; The external screw thread 42 that the upper edge of the socket 41 of the upper end of puncture needle or connection tube has a circle to match with the screw thread 51 of the inwall of snap close 5.In figure, 43 is the fin on socket 41, and socket 41 can be made to be convenient to hold with a hand, rotate.
As shown in Figure 3, after the socket 41 of the upper end 4 of the plug 31 of the lower end 3 of transfusion device or blood exchange transfusion set and puncture needle or connection tube is plugged together, again snap close 5 is screwed on the external screw thread 42 of the upper edge of the socket 41 of the upper end 4 of puncture needle or connection tube, the flange collar 52 suitable for reading of snap close 5 catches on the flange 32 on the top of the plug 31 of transfusion device or blood exchange transfusion set, plug 31 and socket 41 phase are compressed, effectively can prevent the splice failure of transfusion device or blood exchange transfusion set and puncture needle or connection tube, prevent unexpected generation.
