Description

A device for positioning a needle in an infusion port

Technical Field

The utility model relates to the technical field of medical auxiliary equipment, in particular to a needle positioning device for an infusion port.

Background Art

An implantable intravenous infusion port, consisting of an injection seat and an intravenous catheter, provides patients with long-term venous vascular access. It can be buried and left in the subcutaneous tissue for a long time to infuse chemotherapy drugs, nutritional support, blood transfusion, etc. The common fixation methods are: 1. Ordinary gauze dressings, which are low-cost and easy to obtain, but the gauze shape needs to be trimmed each time, which increases the possibility of infection and the workload of nurses; 2. Butterfly wing needle pad dressings, which are of suitable size, eliminate manual cutting, and reduce workload, but have restrictions on needle type. Due to the fixed shape of the dressing, this dressing is only used for butterfly wing needles.

The existing dressing fixing method has the following defects when used:

The implantable intravenous port will have varying degrees of pump protrusion due to the patient's body shape. For example, if the patient is thin or for other reasons, the implantable intravenous port pump body will protrude too much from the human body surface, resulting in partial hollowness at the junction of the dressing and the needle body after needle placement. The sealing effect at the joint between the needle body and the dressing is poor, and it is easy to become loose and difficult to fix. After using it for several days or being stimulated by the patient's sweat, the fit will be poor. At the same time, most of the fixed dressings available on the market are fixed needle types, such as butterfly wing needles, which lack plasticity and limit the needle types that can be used.

Therefore, in order to solve the above problems, the utility model proposes an infusion port needle positioning device that can avoid the influence of sweat, fully fit the patient's skin surface, and is suitable for different needle types.

DETAILED DESCRIPTION

The following description is used to fully explain the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

Please refer to Figures 1-4. The utility model provides a technical solution: an infusion port needle positioning device, comprising:

A fixing member 100, wherein the fixing member 100 is a porous plastic fixing member, and the fixing member 100 is ring-shaped, and the two end surfaces of the fixing member 100 in the axial direction are a contact surface 101 and a support surface 102 respectively, and a fracture 103 is provided on the fixing member 100, and the fracture 103 extends between the contact surface 101 and the support surface 102 and between the two side surfaces of the fixing member 100 in the radial direction;

The adhesive member 200 covers the contact surface 101 .

By limiting the shape of the fixing part 100, the fixing part 100 can be adhered to the patient's skin surface through the adhesive part 200 of the contact surface 101, wherein the hollow portion inside the fixing part 100 corresponds to the skin protrusion at the patient's intravenous infusion port position, so as to avoid the skin protrusion at the patient's intravenous infusion port position from being scratched by the outside world; when in use, the adhesive part 200 on the contact surface 101 can be arranged in a manner to avoid the protrusion of the patient's intravenous infusion port, ensuring that the adhesive part 200 on the contact surface 101 can contact with relatively flat skin, thereby ensuring the stability of the connection of the fixing part 100, and avoiding the problem of partial hollowness at the junction of the fixing part 100 and the needle body after needle placement, resulting in poor fit after several days of use or stimulation by the patient's sweat.

At the same time, by limiting the material properties of the fixing member 100, after injection needles of different needle types contact the fixing member 100, the fixing member can be deformed accordingly, thereby being suitable for use with injection needles of different needle types and positioning injection needles of different needle types.

In order to make the fixing member 100 fully fit the patient's skin and correspond to the protrusion on the patient's skin caused by the insertion of the intravenous infusion port, the radial cross-section of the fixing member 100 is further circular.

To improve the adhesion effect, the adhesive member 200 further extends outward in the radial direction of the fixing member 100. This allows the adhesive member 200 extending from the fixing member 100 to have a larger contact area with the patient's skin, thereby improving the adhesion stability. Furthermore, the cross-sectional size of the adhesive member 200 is not less than 1.5 times the cross-sectional size of the fixing member 100.

In order to prevent the adhesive 200 from causing significant irritation to the patient's skin during the process of being torn off the patient's skin, the adhesive 200 on the contact surface 101 is further provided with a grid-like groove 201 on the side facing away from the fixing member 100, wherein in order to prevent the groove 201 from affecting the bonding effect of the edge of the adhesive 200, that is, to prevent the edge of the adhesive 200 from warping up, the grid-like groove 201 is arranged in a manner to avoid the inner diameter edge and the outer diameter edge of the fixing member 100.

In one embodiment of the present invention, the fixing member 100 is a fixing member of gelatin sponge, the inner diameter of the fixing member 100 is 3 cm, the outer diameter is 5 cm, and the axial dimension of the fixing member 100 is not less than 0.3 cm. Preferably, the axial dimension of the fixing member 100 is 0.5 cm.

Among them, gelatin sponge is a white or yellow, light and soft sponge-like product. It is light, soft, breathable, and has the ability to absorb wound surface adsorption. It can absorb the patient's sweat to prevent the dressing from becoming airborne and curling up. The sponge product has a smooth edge and no lint, and the risk of infection is lower than that of padding dressings.

Specifically, there are many studies on the prevention and treatment of contact dermatitis caused by intravenous infusion port dressings in China. Literature reports that prednisolone acetate calamine lotion, Repixin, IV3000 transparent dressing combined with hydrocolloid, etc., are helpful in improving and treating contact dermatitis caused by dressings. The fixing part 100 in the device uses medical absorbent gelatin sponge. Gelatin sponge is a simple protein with biological activity. It is a biopolymer material composed of collagen contained in animal skin, tendons and ligaments. It will not cause local allergic reactions and is non-irritating to the skin. It can reduce the possibility of contact dermatitis by reducing the contact surface 101 between the dressing and the skin, and avoid patients' allergic constitution, sweat stimulation, etc., which cause allergic reactions such as itching and rash on the patient's skin.

In addition, gelatin sponge has strong plasticity, is easy to shape, and can be applied to various types of needles. The direction of the needle can be determined arbitrarily. Gelatin sponge is soft, does not adhere to the skin, and is plastic. It does not feel like a foreign body when worn and is soft, comfortable, and fits well.

Furthermore, the infusion port needle positioning device also includes:

A positioning patch 300, the positioning patch 300 covers the support surface 102, and the size of the positioning patch 300 is much larger than the size of the support surface 102. Preferably, the size of the positioning patch 300 is not less than twice the size of the support surface 102. When in use, the fixing member 100 is first fixed to the patient's skin through the adhesive 200, and the infusion needle is connected to the infusion port to complete the needle placement, and the positioning patch 300 is further covered on the infusion needle and the support surface 102, wherein the excess part of the positioning patch 300 is adhered to the surrounding skin of the patient to complete the fixation of the position between the fixing member 100, the infusion needle and the patient's skin. Preferably, the positioning patch 300 is a 3M patch.

In order to reduce the gap between the positioning patch 300 and the patient's skin and improve the fixing effect of the fixing patch 300, further, referring to FIG. 2 , the support surface 102 is covered with the adhesive 200, and in the radial direction of the fixing member 100, the adhesive 200 extends outward to increase the contact area between the adhesive 200 and the positioning patch 300. Furthermore, the outer diameter edge of the support surface 102 is curved toward the contact surface 101 to obtain a larger contact area when the positioning patch 300 and the support surface 102 are squeezed, while avoiding a large gap between the positioning patch 300 and the patient's skin.

To facilitate packaging and transportation, the device further includes: a protective film, which covers the side of the adhesive 200 away from the fixing member 100. The protective film is not shown in the figure. The protective film has the functions of dustproof, anti-fouling, and anti-scratch, which can ensure that the adhesive 200 remains clean and tidy before use, and can extend its service life. When using the adhesive 200, the protective film must be torn off first to expose the adhesive 200 for use. In order to make the overall structure of the device correspond to avoid the protruding part and the outside world from scratching and causing accidental opening, further, the cross-sectional size of the adhesive 200 on the support surface 102 and the adhesive 200 on the contact surface 101 is equal.

Directions:

After the intravenous catheter puncture is completed, the protective film is torn off to expose the adhesive 200 on the contact surface 101, the fixing part 100 is wrapped around the needle body and adhered to the patient's skin through the adhesive 200 on the contact surface 101, the protective film on the adhesive surface on the support surface 102 is torn off, and the positioning patch 300 is adhered. After the pasting is completed, the fixing part 100 is pressed to shape to complete the installation.

In summary, the infusion port needle positioning device is improved based on the principle of traditional dressing fixation. It can better fix the protruding pump body while fixing the needle body, increase the fit between the dressing and the needle, prevent the dressing from loosening and curling, and reduce allergies caused by contact between the dressing and the skin. It can reduce the workload of nurses and reduce the risk of infection in nursing work.

Specifically, the infusion port needle positioning device utilizes the adsorption property of gelatin sponge to absorb exudate and avoid loosening of the dressing. At the same time, its plasticity is used to reduce the hollow part, fix the needle body and the pump body, ensure their stability, better fit the patient's skin, and improve patient comfort; the fixing part 100 adopts a hollow design and can be applied to any needle type. The strong plasticity of gelatin sponge can also arbitrarily set the direction of needle placement and tube routing; the device is composed of a fixing part 100 and an adhesive part 200. The material is easy to obtain and the cost is low, which reduces the economic burden on patients.

The embodiments described above are only used to illustrate the technical ideas and features of the utility model, and their purpose is to enable technicians in this field to understand the content of the utility model and implement it accordingly. The patent scope of the utility model cannot be limited only by this embodiment, that is, any equivalent changes or modifications made according to the spirit disclosed by the utility model still fall within the patent scope of the utility model.
