Description

Technical Field

[0001] The utility model relates to the field of medical supplies, in particular to an anti-puncturing structure for an infusion bag. Background Art

[0002] When preparing the medicine for intravenous injection, the nurse needs to draw the liquid medicine in the medicine bottle with a syringe, then insert the syringe needle into the rubber stopper at the mouth of the infusion bag, and then slowly push the liquid medicine in the syringe into the cavity of the infusion bag. During the operation, it may happen that the syringe needle punctures the bag body of the infusion bag. The nurse needs to pay extra attention to the operation, but it is still easy for novice nurses to puncture the bag body of the infusion bag.

[0003] Therefore, how to design an anti-puncturing structure for an infusion bag that can prevent the bag body from being punctured by the syringe needle when preparing the medicine has become an urgent problem to be solved in the field of medical supplies. Content of the Utility Model

[0005] In order to achieve the above invention purpose, the utility model adopts the following technical scheme:

[0006] An anti-puncturing structure for an infusion bag includes a two-way tube. The two-way tube is arranged at the mouth of the infusion bag. One end of the two-way tube outside the infusion bag is the outer end. A medicine injection head is arranged at the outer end of the two-way tube. A rubber stopper is arranged inside the medicine injection head. One end of the two-way tube inside the infusion bag is the inner end. A protective cover is arranged at the inner end of the two-way tube. The protective cover is provided with a cover opening. The medicine injection head is connected to the cavity of the infusion bag through the cover opening. The two-way tube, the medicine injection head and the protective cover are all made of hard materials.

[0007] Compared with the prior art, the anti-puncturing structure for an infusion bag adopting the above technical scheme has the following beneficial effects:

[0008] When using the anti-puncturing structure for an infusion bag of the utility model to prepare the medicine for intravenous injection, the nurse inserts the syringe needle into the rubber stopper. The protective cover can block the syringe needle from contacting the bag body of the infusion bag, prevent the bag body from being punctured by the syringe needle to cause waste of liquid medicine, improve the success rate of preparing the medicine, and is easy to operate for novice nurses.

[0009] Preferably, the protective cover is in a funnel shape, and the inner diameter of the protective cover gradually increases from near to far away from the two-way tube. The cover opening of the protective cover is relatively large, and the syringe needle after being inserted into the rubber stopper is not easily blocked, so that the liquid medicine in the syringe can be smoothly injected into the cavity of the infusion bag.

[0010] Preferably, a convex ring is provided outside the medicine injection head, and the convex ring is arranged around the outer periphery of the rubber stopper for one circle. The convex ring can be clearly seen by the naked eye of the nurse. The puncture range of the syringe needle is delimited by the convex ring, guiding the nurse to smoothly insert the syringe needle into the rubber stopper and reducing the occurrence of the syringe needle being inserted obliquely.

[0011] Preferably, the two-way tube, the medicine injection head and the protective cover are all made of transparent materials. The nurse can observe the syringe needle after it is inserted into the rubber stopper.

[0012] Preferably, a grip tube is provided between the medicine injection head and the two-way tube. A partition ring is provided at the connection of the grip tube and the medicine injection head, and the partition ring is arranged around the outer periphery of the medicine injection head for one circle. The nurse's finger holds the grip tube, and the contact between the finger and the syringe needle is separated by the partition ring, preventing the finger from being accidentally punctured by the syringe needle and improving the operation safety.

[0013] Preferably, arc-shaped finger protection parts are respectively provided on both sides of the partition ring. The arc-shaped grooves of the finger protection parts face the grip tube, and there is enough space in the arc-shaped grooves of the finger protection parts for the fingers to extend into. When the nurse's finger extends into the arc-shaped groove of the finger protection part, the finger protection part will hook the finger to prevent the grip tube from slipping off.

[0014] Preferably, grooves are respectively provided on both sides of the grip tube. The groove surface is engaged with the finger, and the groove plays a positioning role for the finger, which can prevent the grip tube from rolling in the hand and make the grip more firm.

[0015] Preferably, the groove surface is made of rubber material. The friction of the groove surface is increased to prevent the grip tube from slipping out of the hand. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] To further elaborate on the technical means and effects adopted by the present utility model to achieve the predetermined utility model purpose, the following will, in conjunction with the accompanying drawings and preferred embodiments, elaborate in detail on the specific implementation manners, structures, features and their effects of the present utility model as follows.

[0025] Embodiment 1

[0026] As Figures 1 to 4 shown in the puncture-proof structure of the infusion bag,

[0027] It includes a two-way tube 2, the two-way tube 2 is arranged at the bag opening 10 of the infusion bag, one end of the two-way tube 2 outside the bag body 1 of the infusion bag is the outer end, a medicine injection head 21 is arranged at the outer end of the two-way tube 2, a rubber stopper 22 is arranged inside the medicine injection head 21, one end of the two-way tube 2 inside the bag body 1 of the infusion bag is the inner end, a protective cover 3 is arranged at the inner end of the two-way tube 2, the protective cover 3 is provided with a cover opening 30, the medicine injection head 21 is connected to the bag cavity of the infusion bag through the cover opening 30, and the two-way tube 2, the medicine injection head 21 and the protective cover 3 are all made of hard materials. When preparing the medicine for intravenous injection, the nurse inserts the syringe needle into the rubber stopper 22, and the protective cover 3 can prevent the syringe needle from contacting the bag body 1 of the infusion bag, preventing the bag body 1 from being punctured by the syringe needle and causing waste of the liquid medicine, improving the success rate of preparing the medicine, and being easy for novice nurses to operate.

[0028] Among them, the protective cover 3 is in a funnel shape, and the inner diameter of the protective cover 3 gradually increases from near to far from the two-way tube 2. The cover opening 30 of the protective cover 3 is relatively large, and the syringe needle after being inserted into the rubber stopper 22 is not easily blocked, so that the liquid medicine in the syringe can be smoothly injected into the bag cavity of the infusion bag.

[0029] Referring to Figure 2 , a convex ring 23 is arranged outside the medicine injection head 21, and the convex ring 23 is arranged around the outer circumference of the rubber stopper 22 for one circle. The nurse can clearly see the convex ring 23 with the naked eye. By delimiting the puncture range of the syringe needle through the convex ring 23, the nurse can smoothly insert the syringe needle into the rubber stopper 22, reducing the occurrence of the nurse inserting the syringe needle obliquely.

[0030] Among them, the two-way tube 2, the medicine injection head 21 and the protective cover 3 are all made of transparent materials. The nurse can observe the syringe needle after being inserted into the rubber stopper 22.

[0031] Embodiment 2

[0032] As Figures 5 to 7The anti-puncturing structure of the infusion bag shown. This embodiment is based on Embodiment 1. The difference between this embodiment and Embodiment 1 is that: there is a grip tube 4 between the medicine injection head 21 and the two-way tube 2.
