Description

A safety infusion set

technical field

The utility model relates to the technical field of medical instruments, in particular to a safety infusion set.

Background technique

An infusion set is a common medical device, often used for intravenous infusion, and generally consists of needles, needle caps, infusion hoses, liquid medicine filters, flow rate regulators, drip pots, cork puncturers, and air filters. Some infusion sets are also equipped with injection parts and dosing ports. After the infusion is completed, the medical staff need to pull out the needle from the patient, and then throw the discarded needle and the rest of the discarded infusion set into the medical waste bucket. During this process, the discarded needles are exposed, which may stab the medical staff. Moreover, since the discarded needles have been used, they may carry the source of infection. If the discarded needles with the source of infection scratch the medical staff, the disease may be transmitted to the medical staff, endangering the safety of the medical staff. In addition, the discarded needles are sharps and need to be separated from the non-sharp parts of the discarded infusion sets without needles. Because the exposed discarded needles have the risk of stabbing medical staff, for the personal safety of medical staff, medical institutions usually stipulate that for discarded infusion sets, medical staff only need to throw them into the medical waste bucket, and do not need to separate sharps from them.

Detailed ways

The invention will be described in further detail below in conjunction with specific embodiments.

The infusion set 1 is shown in Fig. 1 and includes an infusion hose 13 and a needle tube 12. The end of the infusion hose 13 is provided with a needle hub 131, and the rear portion of the needle tube 12 is provided with a joint 121. The end of the infusion set 1 is provided with a needle 11 , the needle 11 includes a needle body 111 and a needle handle 112 , and the rear part of the needle body 111 is inserted into the needle handle 112 . The front port of the needle tube 12 covers the handle 112 of the needle head 11 and communicates with the needle body 111 . During the patient's intravenous infusion, the medicinal solution bottle 2 is connected to the first port of the infusion hose 13, and the medicinal solution in the medicinal solution bottle 2 will flow into the infusion hose 13, flow along the infusion hose 13 to the needle hub 131, then flow into the needle tube 12 through the joint 121, and then flow through the needle body 111 and enter the patient's blood vessel (not shown).

The infusion set 1 is provided with a sponge 14 for inserting the discarded needle 11. The sponge 14 is provided with a needle channel 142 for the needle tube 12 to pass through. The sponge 14 is sleeved on the rear of the outer wall of the needle tube 12 through the needle channel 142, away from the needle 11, and will not block the part of the needle tube 12 close to the needle 11. As shown in FIG. 3 , the outer wall of the sponge 14 is covered with a protective cover 15 made of TEP material, and the inner wall of the protective cover 15 is bonded to the outer wall of the sponge 14 . The sponge 14 is a strip coaxial with the needle tube 12, and its left and right side edges are parallel to the axis of the needle tube 12. Adhesive plasters 141 protrude from the two side edges, and the adhesive plasters 141 are fixed on the sponge 14 by glue bonding. The outer wall of the protective cover 15 is correspondingly provided with an opening 151 at the position of the adhesive tape 141 . There are two openings 151 in total. During infusion, the needle body 111 is pierced into the patient's body. The infusion set 1 provided in this embodiment has its own adhesive tape 141, so the medical personnel do not need to prepare their own adhesive tape. They only need to paste the adhesive layer 1411 on the front side of the adhesive tape 141 on the patient's skin, and then the sponge 14 and the needle tube 12 can be fixed on the patient's skin, thereby preventing the needle 11 from shifting. After the infusion is completed, the medical staff can insert the discarded needle 11 into the sponge 14 after taking out the needle 11. As shown in the A part in FIG. Since the protective sheath 15 is provided on the outer wall of the sponge 14, the protective sheath 15 can prevent the sponge 14 from being broken and damaged, and can also prevent the needle 11 from penetrating the sponge 14 and stabbing others. In the process of inserting the discarded needle 11 into the sponge 14, the medical staff does not need to expend too much energy to prevent the discarded needle 11 from penetrating the sponge 14, and only needs to insert the discarded needle 11 into the sponge 14 at will. After the medical personnel have disposed of the discarded needles 11, they tear off the adhesive plaster 141, wrap the adhesive layer 1411 on the front side of the adhesive plaster 141 around the discarded needles 11 (not shown), so that the discarded needles 11 are firmly fixed on the sponge 14, and then pull the joint 121 from the needle holder 131, as shown in Figure 2, so that the sharps part A with the needle 11 of the discarded infusion set 1 is separated from the non-sharp part B without the needle 11. The organization does not need to arrange staff to separate the sharps from the discarded infusion set 1, which saves the cost of sharps disposal.

The above is only the embodiment of the invention, and does not limit the scope of patent protection. Persons skilled in the art make insubstantial changes or replacements on the basis of the invention, which still fall within the scope of patent protection.
