Detailed Description

The utility model is further described in detail below in connection with the detailed description.

The infusion apparatus 1 is shown in fig. 1, and comprises an infusion hose 13 and a needle tube 12, wherein the tail end of the infusion hose 13 is provided with a needle seat 131, the rear part of the needle tube 12 is provided with a joint 121, and the joint 121 is detachably inserted on the needle seat 131 to enable the needle tube 12 to be communicated with the infusion hose 13. The end of the transfusion device 1 is provided with a needle 11, the needle 11 comprises 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 end of the needle tube 12 is sleeved on the needle handle 112 of the needle 11 and is communicated with the needle body 111. During intravenous infusion of a patient, the liquid medicine bottle 2 is communicated with the head port of the infusion hose 13, so that the liquid medicine in the liquid medicine bottle 2 flows into the infusion hose 13, flows to the needle seat 131 along the infusion hose 13, flows into the needle tube 12 through the connector 121, flows through the needle body 111 and is input into a blood vessel (not shown) of the patient.

The transfusion device 1 is provided with the sponge 14 for inserting the waste needle 11, the sponge 14 is provided with the needle tube channel 142 for the needle tube 12 to pass through, the sponge 14 is sleeved at the rear part of the outer wall of the needle tube 12 through the needle tube channel 142, the needle 11 is far away, the part of the needle tube 12, which is close to the needle 11, is not shielded, and the transfusion device is convenient for medical staff to observe whether blood flows back or not when a patient is transfused. Referring to fig. 3, a protective sleeve 15 made of TEP material is sleeved on the outer side wall of the sponge 14, and the inner wall of the protective sleeve 15 is adhered to the outer side wall of the sponge 14. The sponge 14 is a bar coaxial with the needle tube 12, the side edges of the left and right sides are parallel to the axis of the needle tube 12, adhesive tape patches 141 are respectively extended from the two side edges, and the adhesive tape patches 141 are specifically fixed on the sponge 14 by glue adhesion. The outer wall of the protective sleeve 15 is correspondingly provided with two openings 151 at the position of the adhesive plaster 141, and the adhesive plaster 141 on the sponge 14 extends outwards from the openings 151 to the outer side of the protective sleeve 15. During infusion, the needle 111 is inserted into the patient. The infusion apparatus 1 according to this embodiment is provided with the adhesive tape 141, so that the medical staff can fix the sponge 14 together with the needle tube 12 on the skin of the patient without self-providing the adhesive tape and by only adhering the adhesive layer 1411 on the front surface of the adhesive tape 141 to the skin of the patient, thereby preventing the needle 11 from being displaced. After the transfusion is finished, medical staff can insert the waste needle 11 into the sponge 14 after taking out the needle 11, and as shown in the part A in fig. 2, the waste needle 11 can be wrapped by the sponge 14 and cannot be exposed to hurt other people. Because the protective sleeve 15 is arranged on the outer side wall of the sponge 14, the protective sleeve 15 can avoid the breakage and damage of the sponge 14, can prevent the needle 11 from stabbing other people due to the penetration of the sponge 14, and can prevent the waste needle 11 from penetrating the sponge 14 without consuming too much effort when medical staff inserts the waste needle 11 into the sponge 14, and only needs to insert the waste needle 11 into the sponge 14 by hand. After the medical staff processes the waste needle 11, the adhesive tape 141 is torn off, the waste needle 11 (not shown) is entangled by the adhesive layer 1411 on the front surface of the adhesive tape 141, the waste needle 11 is firmly fixed on the sponge 14, then the joint 121 is pulled out from the needle seat 131, as shown in fig. 2, the sharp device part A with the needle 11 of the waste transfusion device 1 is separated from the non-sharp device part B without the needle 11, so that the medical institution does not need to additionally arrange the staff to separate the sharp device of the waste transfusion device 1, and the sharp device processing cost is saved.

The above-described embodiments are provided for the present utility model only and are not intended to limit the scope of patent protection.
