Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an anti-dropout intravenous infusion set. Background Art

[0002] An infusion set, or infusion pump, is a medical device used for infusion. The traditional infusion method is to hang the liquid in a bottle or infusion bag at a high place, and use gravity to make the liquid flow into the vein through the infusion tube. The flow rate is manually adjusted by the clip on the tube, and the adjustment index is the dripping speed in the dropper.

[0003] During clinical infusion, the inlet is usually plugged into the infusion bottle or bag, and the outlet is usually fixed on the arm with tape. The phenomenon of the infusion set being pulled off is common during the infusion process. Most of the time, it is caused by the patient turning over, taking things, or the nurse's work clothes hanging on the infusion set during various operations. Therefore, we propose an anti-dropout intravenous infusion set to solve the above problems.

[0004] The above information disclosed in this background technology is only used to increase the understanding of the background technology of the present invention and therefore, it may include information that does not constitute the prior art known to ordinary technicians in this field. Utility Model Content

[0005] The purpose of the utility model is to provide an anti-dropout intravenous infusion set to solve the problems in the current market raised by the above background technology.

[0006] In order to achieve the above object, the utility model provides an anti-dropout intravenous infusion set, comprising:

[0007] An infusion hose, one end of which is connected to a plug and the other end of which is connected to a venous needle, and a baffle is provided on the plug;

[0008] A connecting cover, wherein the connecting cover is movably connected to the plug, and a card slot adapted to a card block on the side of the infusion bottle is provided on the inner wall of the connecting cover;

[0009] The wrist pad is arranged on the infusion hose through a connecting sleeve.

[0010] Preferably, the connection cover is sleeved on the outside of the plug through the through hole in the middle, and a limiting groove connected with the through hole is provided on the connection cover, and the limiting groove is matched with the blocking piece.

[0011] Preferably, the infusion hose is provided with a drip pot and a flow rate regulator.

[0012] Preferably, a first veneer extends from one end of the wrist pad and a second veneer that fits with the first veneer is provided at the other end.

[0013] Preferably, the connecting sleeve is fitted to the outer surface of the infusion hose.

[0014] Preferably, the diameter of the baffle is larger than the diameter of the through hole.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] (1) The utility model is provided with a connection cover and a plug that are movably connected. A card slot that is compatible with a card block on the side of the infusion bottle is opened on the inner wall of the connection cover. When the plug is used to connect the infusion bottle, the connection cover is directly pressed and connected to the infusion bottle at the same time, thereby increasing its firmness and preventing the plug from falling off and affecting the infusion. It is easy to use.

[0017] (2) The utility model is provided with a wrist pad which is mounted on the infusion hose through a connecting sleeve. After the intravenous needle is inserted, the wrist pad is dragged to a suitable position and tied to the patient's arm or wrist to prevent the intravenous needle from being accidentally touched or pulled out, thereby improving the safety of infusion.

[0018] The above summary is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments and features described above, further aspects, embodiments and features of the present invention will be readily apparent by reference to the accompanying drawings and the following detailed description.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. It should be pointed out that the drawings are schematic and not drawn to scale.

[0025] See also Figure 1-Figure 4 , an anti-dropout intravenous infusion set, comprising:

[0026] An infusion hose 1, one end of the infusion hose 1 is connected to a plug 2 and the other end is connected to a venous needle 3, a baffle 201 is provided on the plug 2; a drip pot 6 and a flow rate regulator 7 are provided on the infusion hose 1;

[0027] A connecting cover 4 is movably connected to the plug 2. A card slot 403 is provided on the inner wall of the connecting cover 4 to match the card block 501 on the side of the infusion bottle 5 or the infusion bag. A card block 501 is provided on the side of the liquid outlet of the infusion bottle 5 or the infusion bag.

[0028] The wrist pad 9 is mounted on the infusion hose 1 through the connecting sleeve 8. The connecting sleeve 8 fits the outer surface of the infusion hose 1. The infusion hose 1 is dragged by a force perpendicular to the connecting sleeve 8 to adjust the position of the wrist pad 9 on the infusion hose 1. When an inclined force acts on the infusion hose 1, it is difficult to drag the connecting sleeve 8 to move on the infusion hose 1, thereby reducing the risk of the intravenous needle 3 being pulled off.

[0029] A veneer 10 extends from one end of the wrist pad 9 and a veneer 2 11 is provided at the other end to fit with the veneer 10. The wrist pad 9 is very convenient to fix and can be suitable for the arm circumferences of different patients.

[0030] The connection cover 4 is sleeved on the outside of the plug 2 through the through hole 401 in the middle, and a limiting groove 402 connected with the through hole 401 is provided on the connection cover 4. The limiting groove 402 is adapted to the blocking piece 201, and the diameter of the blocking piece 201 is larger than the diameter of the through hole 401. When operating the plug 2, while inserting the plug 2 into the infusion bottle 5, the connection cover 4 is directly pressed and engaged with the infusion bottle 5, which increases its firmness, prevents the plug 2 from falling off and affecting the infusion, and is convenient to use.

[0031] Working principle of this embodiment: when using the anti-dropout intravenous infusion set, first, insert the plug 2 into the infusion bottle 5, and at the same time press the connecting cover 4 to make it snap into the infusion bottle 5, thereby increasing its firmness and preventing the plug 2 from falling off and affecting the infusion; after the needle is inserted, drag the connecting sleeve 8 to a suitable position and tie it to the patient's arm or wrist to prevent the intravenous needle 3 from being accidentally touched or pulled out, thereby improving the safety of the infusion.
