Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, in particular to an infusion port needle fixing device for children with tumors. Background Art

[0002] An infusion port is a device specifically for infusion, mainly for patients who need long-term, repeated infusion of chemotherapy drugs. The infusion port needs to be implanted in the patient's body, which includes the tip of the superior vena cava, the middle catheter that sneaks into the blood vessel, and the injection seat under the skin. Patients can work, live and eat normally, and take a bath at the same time; when the patient needs to be infused, it is generally disinfected locally, and then the infusion needle is inserted into the injection seat. The use of an infusion port can reduce the number of blood vessel punctures, protect blood vessels, reduce drug extravasation and reduce the risk of infection.

[0003] Clinically, when younger pediatric cancer patients use infusion ports, due to their lack of cooperation, they often use their hands to pull the catheter of the external infusion needle (port needle). Although the doctor has used medical tape to stick and fix the injection seat, port needle and port needle catheter during infusion, the port needle of the infusion port is often pulled loose or the needle slips out due to frequent pulling or sweating by the children.

[0004] In view of this, it is particularly important to provide a device for reinforcing and protecting the port needle and catheter of the infusion port used for pediatric tumor patients. Utility Model Content

[0005] In view of the deficiencies existing in the above-mentioned prior art, the utility model proposes an infusion port needle fixing device for pediatric tumor patients, which uses a limit cover to partially limit the injection seat of the infusion port, and uses a binding component to restrict the limit cover to the chest of the child for overall fixation, and uses a protective tube component to wrap and protect the port needle catheter to prevent the child from pulling the port needle catheter, thereby solving the problems existing in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A device for fixing an infusion port needle for children with tumors comprises a limiting cover, a binding assembly and a protective tube assembly. The binding assembly and the protective tube assembly are both connected to the limiting cover. The protective tube assembly is sleeved on the outside of a catheter connected to the port needle. The limiting cover is fixed to the front chest of the patient through the binding assembly.

[0008] A further preferred embodiment of the above technical solution is as follows: the limiting cover is a hollow cone, the upper surface diameter of the hollow cone is 25-30 mm, the lower surface diameter of the hollow cone is 30-40 mm, and the height is 15-20 mm.

[0009] By adopting the above solution, further, at least one pressure-proof hole is opened on the side wall of the bottom end of the limiting cover, and the pressure-proof hole and the protective tube assembly are located on the same axis.

[0010] A further preferred embodiment of the above technical solution is as follows: the binding assembly includes two binding straps and at least one reinforcement strap, the two binding straps are symmetrically connected to the left and right sides of the limiting cover, one end of the reinforcement strap is connected to the limiting cover, and the other end is passed around the patient's shoulder and connected to the binding strap.

[0011] Based on the above technical solution, further, the binding belt is movably connected to the limiting cover through a connecting ring.

[0012] By adopting the above solution, further, a matching portion is commonly provided at the ends of the two binding straps, and the ends of the two binding straps are fixed by the matching portion. The matching portion includes a first thorny surface connected to one of the binding straps and a first velvet surface connected to the other binding strap.

[0013] A further preferred embodiment of the above technical solution is as follows: the protective tube assembly includes an extension belt and a protective belt, one end of the extension belt is fixedly connected to the limiting cover, and the other end of the extension belt is fixedly connected to the protective belt.

[0014] By adopting the above solution, further, the bottom surface and the top surface of the protective belt are respectively provided with a second thorny surface and a second velvet surface that match each other.

[0015] The utility model has the following beneficial effects by adopting the above technical solution:

[0016] 1. By setting a limit cover and a binding assembly, the injection seat of the infusion port on the chest of the child is buckled and limited within a predetermined range by using the limit cover, and then fixed by a binding belt and a reinforcement belt, the injection seat of the infusion port in the child's body is effectively restricted.

[0017] 2. By setting up a protective tube assembly, the free section of the port needle catheter outside the child's body is wrapped and protected with a protective belt, so that the child cannot directly touch the port needle catheter, effectively avoiding the problem of the port needle needle slipping due to the child's grasping and pulling it.

[0018] 3. The utility model cooperates with the limiting cover, the binding assembly and the protective tube assembly to limit the fixed seat of the infusion port while protecting the port needle catheter outside the child's body. Even if the child grabs the protective belt to drag it, the needle of the port needle will not be affected due to the limiting effect of the two binding belts and one reinforcement belt, which effectively avoids the problem of the needle loosening caused by the child pulling the port needle catheter.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical scheme and advantages of the embodiment of the utility model clearer, the technical scheme in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the following description is only a part of the embodiment of the utility model. For ordinary technicians in this field, other embodiments can be obtained based on these embodiments without creative work.

[0027] For ease of understanding, the words "upper", "lower", "left", "right", "front", "back" and so on used in this application are all based on the present invention. Figure 1 In the direction shown.

[0028] At present, when pediatric tumor patients use infusion ports in clinical practice, the doctor disinfects the external skin of the child where the infusion port is inserted, inserts the butterfly needle (infusion needle / port needle) at the injection seat, and then sticks the injection seat, port needle, and the catheter connected to the port needle to the child's skin through medical tape. Despite this, young children have low adaptability and cooperation ability, and often pull or drag the port needle catheter with their hands, and occasionally the port needle needle is pulled out. Sometimes the tape is loosened due to sweating of the child, causing the port needle needle to slip out; therefore, the applicant designed an integrated structure of a wrapped restrictive infusion port and a protective port needle catheter, as follows: Embodiment 1:

The binding component 2 is connected to the left and right sides of the limiting cover 1. The limiting cover 1 is fixed to the front chest of the child tumor patient through the binding component 2. The protective tube component 3 is connected to the limiting cover 1 and is sleeved on the outside of the catheter connected to the port needle. The port needle catheter outside the child's body is wrapped and protected by the protective tube component 3 to prevent the needle from loosening due to the child's hand pulling the port needle catheter.

[0030] Specifically, the limiting cover 1 is a hollow cone without an upper bottom surface and a lower bottom surface. The diameter of the upper surface of the hollow cone is 25-30 mm, the diameter of the lower surface of the hollow cone is 30-40 mm, and the height is 15-20 mm. The size of the lower bottom of the limiting cover 1 is determined according to the size of the protrusion when the injection seat is located under the skin of the child's chest. Usually, the size of the protrusion is about 30 mm. The injection seat in the child's body is reasonably limited by the limiting cover 1; further, at least one anti-pressure hole 11 is opened on the side wall of the bottom end of the limiting cover 1. In the present embodiment, there are two anti-pressure holes, which are respectively opened on the front and rear side walls of the limiting cover. Through the setting of the two anti-pressure holes 11, the infusion port catheter in the child's body and the port needle catheter outside the child's body are avoided from being squeezed.

[0031] like Figure 2As shown, the binding assembly 2 includes two binding straps 21 and a reinforcement strap 22, and the two binding straps 21 are symmetrically connected to the limiting cover 1.
