Description

Technical Field

[0001] The utility model relates to the technical field of medical appliances, and particularly relates to a detaining needle fixator. Background Art

[0002] A detaining needle is a device commonly used in clinical medicine, and is usually used in treatment processes such as intravenous infusion, drug injection, and blood collection. The use of a detaining needle can reduce the discomfort and complications caused by frequent punctures of patients. However, since the detaining needle needs to be left in the patient's body for a long time, the reliability and comfort of its fixation method are crucial. The traditional method for fixing a detaining needle mainly relies on directly fixing the detaining needle on the skin surface with adhesive tape or tape. However, this fixing method often has multiple problems. First, directly using adhesive tape for pasting easily causes skin allergies, redness, and even infections, especially during long-term use. Second, the fixing method with adhesive tape is prone to loosening during the patient's movement, resulting in a change in the position of the detaining needle, which not only affects the infusion effect but also may cause unnecessary medical risks. In addition, during certain special operation processes, such as the replacement of an infusion pipeline or drug injection, the loose fixing method may cause the accidental detachment of the detaining needle, bringing inconvenience to medical staff and increasing the pain and treatment cost of patients. Therefore, it is particularly important to develop a detaining needle fixator with a reasonable structure, reliable fixation, and comfortable use. Content of the Utility Model

[0003] Aiming at the above existing technical deficiencies, the purpose of the utility model is to provide a detaining needle fixator, which can reduce the discomfort of patients and improve the efficiency and safety of medical care.

[0021] The present utility model will be further described below with reference to the accompanying drawings.

[0022] As Figures 1 to 5 shown, a retaining needle fixator includes an adhesive patch 22, an adhesive tape 24, a silica gel cushion block 23 and a buckle 21; the silica gel cushion block 23 is placed on the upper part of the adhesive patch 22 and is fixedly adhered to the silica gel cushion block 23 through the adhesive tape 24; a mounting block 232 is fixedly arranged on the upper end surface of the silica gel cushion block 23, and a card slot 238 is arranged in the mounting block 232; an opening 235 communicating with the card slot 238 is arranged on one side of the silica gel cushion block 23, and the bottom of the buckle 21 is inserted and installed in the card slot 238 from the opening 235; a support seat 233 is fixedly arranged on the silica gel cushion block 23; the support seat 233 is located in the middle of the mounting block 232; the thickness of the support seat 233 gradually increases from one end close to the opening 235 to the other end; an arc-shaped limiting groove 239 adapted to the retaining needle 1 is arranged on the upper part of the mounting block 232; a plurality of ventilation through holes 237 are arranged on the mounting block 232; the ventilation through holes 237 penetrate through the mounting block 232 from top to bottom.

[0023] The adhesive patch 22, as a key underlying component of the retaining needle fixator 2, is carefully manufactured using high-quality medical-grade adhesive materials. This material has been strictly screened and tested to ensure no irritation to the patient's skin and high adhesiveness. The adhesive patch 22 can closely adhere to the patient's skin, and even in the case of patient movement or slight sweating, it can maintain a stable pasting effect, providing a solid support foundation for the entire fixator 2 system. Its unique adhesive formula enables easy removal without residue, reducing the discomfort of the patient.

[0024] The tape 24, as a further enhancing element for the stability of the fixator 2, skillfully passes through the precisely positioned slots 234 on the silicone cushion block 23 and forms a tight union with the adhesive patch 22. Its elastic design enables the tape 24 to adapt to the complex curvatures of different parts of the human body, ensuring that the fixator 2 can achieve fitting and stability on the skin at different positions. This adaptability of the tape 24 not only improves the wearing comfort of the patient but also enhances the overall stability of the fixator 2, effectively preventing the loosening or detachment of the fixator 2 caused by the patient's activities or changes in body position.

[0025] The silicone cushion block 23, as an important bridge connecting the adhesive patch 22 and the mounting block 232, is made of high-purity, soft, and highly elastic medical-grade silicone. This material not only has excellent biocompatibility, which can reduce irritation and allergic reactions to the patient's skin, but also effectively disperses the pressure exerted by the fixator 2 on the skin due to its good elasticity, significantly improving the wearing comfort of the patient. The mounting block 232 on the upper part of the silicone cushion block 23 is exquisitely designed. The precise layout of the card slots 238 and the openings 235 facilitates the installation of the buckle 21. At the same time, the smooth surface treatment reduces the friction with the skin, further enhancing the wearing experience.

[0026] The mounting block 232, as the core component of the fixator 2, the precise design of the internal card slot 238 and the perfect match with the buckle 21 ensure the stable fixation of the indwelling needle 1. The arc-shaped limiting slot 239 on the upper part of the mounting block 232 is carefully measured and polished, which can closely fit various models of indwelling needles 1, effectively preventing their shaking or displacement. In addition, multiple ventilation through holes 237 are ingeniously arranged on the mounting block 232. While ensuring the structural strength of the fixator 2, these through holes enable the free flow of air, effectively reducing the risk of skin dampness and redness caused by long-term wearing.

[0027] The support base 233, as an auxiliary support structure for the mounting block 232, is made of a lightweight and strong material. The unique design of the support base 233 - the thickness gradually increases from one end close to the opening 235 to the other end - not only facilitates the smooth insertion and fixation of the buckle 21 but also ingeniously supports the positive pressure connector, keeping it at a certain distance from the patient's skin. At the same time, it is convenient for the nurse to pinch the positive pressure connector to remove or install the buckle 21 from the mounting block 232. The setting of the support base 233 effectively avoids the problem of pressure sores caused by the direct pressure of the positive pressure connector on the skin, further enhancing the comfort and safety of the patient.

[0028] In this embodiment, an extension plate 231 is fixedly arranged on the side of the mounting block 232; a positioning slot 234 adapted to the tape 24 is arranged on the extension plate 231, and the middle part of the tape 24 is clamped in the positioning slot 234.

[0029] In this embodiment, the cross-sectional shape of the mounting block 232 is rectangular; there are four extension plates 231, which are respectively arranged on the four side surfaces of the mounting block 232; there are four tapes 24 corresponding to the extension plates 231, and the four sides of the mounting block 232 are fixed by the four tapes 24.

[0030] In this embodiment, a groove is provided at the lower part of the mounting block 232; a breathable soft pad 25 is arranged in the groove; the thickness of the breathable soft pad 25 is greater than the depth of the groove; the lower end surface of the breathable soft pad 25 abuts against the upper end surface of the silica gel cushion block 23. It ensures breathability and improves comfort at the same time. When the breathable soft pad 25 gets dirty, it is easy to replace.

[0031] In this embodiment, the buckle 21 includes a first C-shaped plate 215, a second C-shaped plate 212 and a connecting plate 211; the first C-shaped plate 215 is placed on one side of the second C-shaped plate 212; both ends of the connecting plate 211 are fixedly connected to the first C-shaped plate 215 and the second C-shaped plate 212 respectively; the axes of the first C-shaped plate 215 and the second C-shaped plate 212 intersect obliquely, and the overall structure of the buckle 21 is adapted to the positive pressure joint of the indwelling needle 1.

[0032] The buckle 21 is made of high-strength and corrosion-resistant materials. Its unique design of the first C-shaped plate 215 and the second C-shaped plate 212 achieves a double fixation effect on the positive pressure joint of the indwelling needle 1. The first C-shaped plate 215 precisely clamps at the position of the heparin cap, while the second C-shaped plate 212 firmly clamps at the white end cap. This double locking mechanism greatly enhances the reliability and safety of the fixation. The connecting plate 211 part of the buckle 21 is strengthened to ensure the stability and durability of the overall structure, and it can maintain a stable fixation effect even in a complex and changeable medical environment.

[0033] In this embodiment, a support plate 213 is fixedly arranged at the lower end of the first C-shaped plate 215; a guide bar 214 is fixedly arranged on one side of the bottom of the support plate 213; a guide groove 236 adapted to the guide bar 214 is arranged on the mounting block 232; the guide bar 214 is communicated with the card slot 238 and the opening 235. Insert the guide bar 214 into the guide groove 236 from the opening 235 to fix the buckle 21.

[0034] In this embodiment, a plurality of cavities are arranged inside the support seat 233 to further reduce the overall weight.

[0035] Working principle:

[0036] Stick the adhesive patch 22 on the dressing of the indwelling needle 1, then place the silicone cushion block 23 on the adhesive patch 22, snap the middle part of the tape 24 into the positioning groove 234 of the extension plate 231, and stick the tape 24 on the adhesive patch 22; then buckle the buckle 21 on the positive pressure connector of the indwelling needle 1, where the first C-shaped plate 215 is stuck at the heparin cap of the positive pressure connector, and the second C-shaped plate 212 is stuck at the white end cap, and then insert the buckle 21 into the card slot 238 from the opening 235 of the mounting block 232 to fix the buckle 21 on the mounting block 232, thereby fixing the positive pressure connector; the setting of the second C-shaped plate 212 can prevent the positive pressure connector from rotating around its axis, resulting in the torsion of the infusion tube; the structure of the support seat 233 with one side having a lower thickness and the other side having a higher thickness has the following effect: during the process of pushing the buckle 21 into the card slot 238, as the distance between the first C-shaped plate 215 and the support seat 233 gradually decreases, the positive pressure connector is pressed tighter and tighter, and at the same time, the heparin cap end and the white end cap end of the positive pressure connector can be lifted away from the patient's skin, facilitating other operations; the setting of the support seat 233 can keep the positive pressure connector away from the patient's skin, avoiding the problem of pressure injury; when it is necessary to remove the positive pressure connector for operations such as infusion, just push the buckle 21 out of the card slot 238, and there is no need to replace the new tape 24.
