Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of syringes, and particularly relates to a protective intravenous syringe. Background Art
[0002] A disposable infusion set is a relatively common medical consumable. It is frequently used in the treatment of diseases because intravenous injection works quickly. The infusion set is used to establish a channel between the human veins and the drug solution, allowing the drug solution to enter the patient's veins through a syringe.
[0003] However, the following shortcomings exist in the use of existing intravenous syringes: the injection needle is relatively sharp, and after the injection is completed, the injection needle is exposed to the air. Medical staff are very likely to be accidentally injured when collecting discarded syringes, which affects the health of medical staff. Therefore, medical staff will insert the injection needle into the rubber stopper of the infusion bottle, but the injection needle inserted into the rubber stopper of the infusion bottle is prone to fall off. Utility Model Content
[0004] The purpose of the utility model is to provide an intravenous syringe with protection to overcome the shortcomings of the above technology.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A protective intravenous syringe comprises a bottle stopper piercer, a drip pot, an infusion hose, a flow rate regulator, an injection needle and a protection box. The top of the infusion hose is provided with a bottle stopper piercer, the bottle stopper piercer is connected with the infusion hose, and the bottle stopper piercer is used to pierce the infusion bottle so that the medicine in the infusion bottle flows into the infusion hose. The middle part of the infusion hose is connected with a drip pot, and the tail end of the infusion hose is provided with an injection needle. The drip pot and the injection needle are connected with each other through the infusion hose. The outer wall of the infusion hose is also provided with a protection box, and the injection needle can be stuck into the protection box after the injection is completed to prevent accidental injury.
[0007] Preferably, the outer side wall of the infusion hose is also provided with a flow rate regulator, and the degree of compression of the infusion hose is controlled by the flow rate regulator to adjust the flow rate of the drug solution passing through the infusion hose and thus control the speed of infusion.
[0008] Preferably, the protective box comprises a box body and a clamping hole. The side wall of the box body is provided with a clamping hole, and the injection needle is clamped into the box body through the clamping hole.
[0009] Preferably, the protective box also includes a card plate, a connecting plate, and a spring. The card plates are provided in two groups and are symmetrically distributed. A connecting plate is fixedly provided at one end of the card plate, and a spring is provided on one side of the connecting plate. During use, the used injection needle is inserted between the two groups of card plates. During the insertion process, the two groups of connecting plates are squeezed, causing the two groups of card plates to move in opposite directions respectively, thereby causing the spring to be squeezed and deformed. The spring has the potential energy to return to its original state when squeezed, and then reacts on the connecting plate, driving the connecting plate to make the two groups of card plates clamp the injection needle to prevent the injection needle from falling off.
[0010] Preferably, a guide bar is provided on one side of the card plate, and the guide bar makes the movement of the card plate more stable to prevent shaking.
[0011] Preferably, the end of the clamping plate is arc-shaped to facilitate the insertion of the injection needle.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] After completing the infusion, the injection needle is inserted into the protective box to prevent medical staff from being accidentally injured. During use, the used injection needle is inserted between the two sets of clamping plates. During the insertion process, the two sets of connecting plates are squeezed, causing the two sets of clamping plates to move in opposite directions, thereby causing the spring to be squeezed and deformed. The spring has the potential energy to return to its original state when squeezed, and then reacts on the connecting plate, driving the connecting plate to make the two sets of clamping plates clamp the injection needle to prevent the injection needle from falling off.

[0018] To facilitate the understanding of those skilled in the art, Figure 1-3 , the technical solution of the utility model is further specifically described.
[0019] A protective intravenous syringe comprises a bottle stopper piercer 1, a drip pot 2, an infusion hose 3, a flow rate regulator 4, an injection needle 5 and a protection box 6. The top of the infusion hose 3 is provided with a bottle stopper piercer 1, the bottle stopper piercer 1 is connected with the infusion hose 3, and the bottle stopper piercer 1 is used to pierce the infusion bottle so that the medicine in the infusion bottle flows into the infusion hose 3. The middle part of the infusion hose 3 is connected with the drip pot 2, and the tail end of the infusion hose 3 is provided with an injection needle 5. The drip pot 2 and the injection needle 5 are connected to each other through the infusion hose 3. The outer wall of the infusion hose 3 is also provided with a protection box 6, and the injection needle 5 can be inserted into the protection box 6 after the injection is completed to prevent accidental injury.
[0020] The outer wall of the infusion hose 3 is also provided with a flow rate regulator 4, which controls the degree of compression of the infusion hose 3 to adjust the flow rate of the drug solution passing through the infusion hose 3 and thus control the speed of infusion.
[0021] The protective box 6 includes a box body 61, a card hole 62, a card plate 63, a guide strip 64, a connecting plate 65, and a spring 66. The card plates 63 are provided in two groups and are symmetrically distributed. A connecting plate 65 is fixedly provided at one end of the card plate 63, a spring 66 is provided on one side of the connecting plate 65, and a guide strip 64 is provided on one side of the card plate 63. A card hole 62 is provided on the side wall of the box body 61. The injection needle 5 is inserted into the box body 61 through the card hole 62. The end of the card plate 63 is arc-shaped to facilitate the insertion of the injection needle 5. The guide strip 64 makes the movement of the card plate 63 more stable to prevent shaking.
[0022] During use, the used injection needle 5 is inserted between the two groups of clamping plates 63. During the insertion process, the two groups of connecting plates 65 are squeezed, causing the two groups of clamping plates 63 to move in opposite directions, thereby causing the spring 66 to be squeezed and deformed. The spring 66 has the potential energy to return to its original state after being squeezed, and then reacts on the connecting plate 65, driving the connecting plate 65 to make the two groups of clamping plates 63 clamp the injection needle 5 to prevent the injection needle 5 from falling off.
