Description

Technical Field

[0001] The utility model belongs to the technical field of blood transfusion apparatuses, and in particular relates to a blood transfusion apparatus capable of rapid exhaust and preventing it from falling off. Background Art

[0002] In the medical industry, some emergency patients need blood transfusions, and a blood transfusion device is needed for blood transfusion. A blood transfusion device is a device that can quickly transport blood in a blood bag into the patient's body.

[0003] During use, existing blood transfusion devices are prone to bubbles in the internal pipelines, and the way to eliminate the bubbles is for the nurse to roll up the pipeline to allow the bubbles to flow back into the dropper. This operation method is relatively cumbersome and overly dependent on nurses. At the same time, the bottle stopper puncture needle lacks an anti-fall-off binding mechanism with the blood transfusion bag, and is prone to separation and falling due to force, which has certain limitations in use. Utility Model Content

[0004] The utility model aims to provide a blood transfusion set with anti-falling function that can be quickly exhausted, so as to solve the problem that bubbles are easily generated in the internal pipeline of the existing blood transfusion set proposed in the above background technology during use, and the method for eliminating the generated bubbles is that the nurse rolls up the pipeline to make the bubbles flow back into the dropper. This operation method is relatively troublesome and relies too much on nurses. At the same time, the bottle stopper puncture needle lacks an anti-falling binding mechanism with the blood transfusion bag, which is easy to separate and fall off due to force, and there are certain limitations in use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a blood transfusion device with anti-falling function that can quickly exhaust air, comprising a blood transfusion device main body, the blood transfusion device main body comprising a dropper, the upper and lower sides of the dropper are penetrated and connected with pipeline 1 and pipeline 2, the end of the pipeline 1 away from the dropper is connected and installed with a bottle stopper puncture needle, the end of the pipeline 2 away from the dropper is connected and installed with a venous puncture needle, the outer surface of the pipeline 2 is provided with a flow stop clamp 1, the pipeline 2 is connected and installed with an exhaust pipe, the outer surface of the exhaust pipe is provided with a flow stop clamp 2, the outside of the bottle stopper puncture needle and the outside of the venous puncture needle are both movably provided with protective covers, the outside of the bottle stopper puncture needle is movably provided with two anti-falling straps, and the two anti-falling straps are used in conjunction with each other.

[0006] By adopting the above scheme, an exhaust pipe is provided in combination with stop-flow clamp one and stop-flow clamp two. When bubbles appear in pipeline two, the bubbles can be quickly discharged by closing stop-flow clamp one and opening stop-flow clamp two, instead of relying entirely on the nurse to roll up pipeline two to drive the bubbles back into the dropper. The operation is convenient and the exhaust operation can be performed quickly. The protective cover is provided in combination with a support ring, an alignment plug plate and a positioning ball to facilitate the insertion of the protective cover, and the protective cover can effectively isolate and protect the bottle stopper puncture needle and the intravenous puncture needle. The anti-falling strap is used in combination with the Velcro male and female stickers, so that it can be stably bound to the surface of the blood transfusion bag, achieving a good anti-falling effect.

[0007] As a preferred embodiment, a male Velcro patch is fixedly installed on the end of the anti-falling strap on one side, and a female Velcro patch is fixedly installed on the end of the anti-falling strap on the other side, and the male Velcro patch and the female Velcro patch are used in combination.

[0008] By adopting the above solution, after the two anti-falling straps are passed around the blood transfusion bag, the two anti-falling straps can be connected and bound by using the Velcro male patch and the Velcro female patch, which is easy to operate.

[0009] As a preferred embodiment, support rings are fixed on the surface of the bottle stopper puncture needle and the surface of the intravenous puncture needle. The support rings are fitted onto the inner wall of the protective cover at corresponding positions. A plurality of retaining balls are fixedly mounted on the outer surface of the support rings. A plurality of retaining grooves are provided on the inner wall of the protective cover. The retaining balls and retaining grooves are used in combination.

[0010] By adopting the above solution, the support ring is used in conjunction with the locking ball to clamp the installed protective cover to prevent the protective cover from accidentally falling off.

[0011] As a preferred implementation, the outer surface of the support ring is provided with a plurality of alignment slots, and the inner wall of the protective cover is provided with a plurality of alignment plug plates used in conjunction with the alignment slots.

[0012] By adopting the above solution, when the protective cover is inserted, the alignment plug plate is inserted into the alignment slot so that the positioning ball faces the positioning slot, which facilitates the alignment assembly of the protective cover.

[0013] As a preferred embodiment, a through-tube is fixedly installed at one end of the anti-falling bandage, grooves are provided on both sides of the bottle stopper puncture needle and a through hole is provided at the position opposite to the groove, the through-tube is located inside the groove at the corresponding position and the same screw is passed through the through hole and the through-tube, and a nut is threadedly installed on the outer surface of the screw.

[0014] By adopting the above scheme, the through-tube is used in conjunction with the screws and nuts, which facilitates the disassembly and assembly of the anti-falling strap and facilitates subsequent disassembly and recycling.

[0015] As a preferred implementation, a sealing plug is provided at one end of the exhaust pipe away from pipeline 2, and the sealing plug is threadedly installed on the end of the exhaust pipe.

[0016] By adopting the above solution, the setting of the sealing plug can strengthen the sealing of the exhaust pipe to avoid leakage.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The anti-dropping blood transfusion device capable of rapid exhaust is used by arranging an exhaust pipe in conjunction with the first and second stop-flow clamps. When bubbles appear in the second pipe, the first stop-flow clamp is closed and the second stop-flow clamp is opened, so that the bubbles can be rapidly exhausted, instead of relying solely on the nurse to roll up the second pipe to drive the bubbles back into the dropper. The operation is convenient and the exhaust operation can be rapidly performed.

[0019] The anti-falling blood transfusion device capable of rapid exhaust is used by arranging a protective cover in conjunction with a support ring, an alignment plug plate and a positioning ball, so that the insertion of the protective cover is convenient, and the protective cover can effectively isolate and protect the bottle stopper puncture needle and the venous puncture needle. The anti-falling strap is used in conjunction with a Velcro male patch and a Velcro female patch, so that it can be stably bound to the surface of the blood transfusion bag, thereby achieving a good anti-falling effect.
