Description

Technical Field

[0001] The utility model relates to the technical field of indwelling needle protection equipment, in particular to a protection device for an indwelling needle. Background Art

[0002] In the medical field, indwelling needles are widely used in patients who need long-term infusion or multiple blood draws. The use of indwelling needles greatly reduces the pain caused by repeated punctures to patients and improves the work efficiency of medical staff. However, in actual use, the fixation and protection of indwelling needles has become an important issue.

[0003] When patients have an indwelling needle in their hand, their arm movements may be restricted because the indwelling needle protrudes from the skin surface and is easily scratched by external objects. This scratching not only causes discomfort and pain to the patient, but may also cause the indwelling needle to shift or fall off, thereby increasing the risk of needle dislocation. In addition, patients also need to be particularly careful when wearing clothes to prevent clothing from rubbing against or getting caught on the indwelling needle, further increasing the possibility of damage to the indwelling needle.

[0004] In order to solve the above problems, medical staff usually use various methods to fix and protect the indwelling needle, such as using tape, bandages, etc.; however, these methods often have disadvantages such as loose fixation and airtightness, which can easily cause discomfort to patients and cannot effectively prevent external objects from scratching the indwelling needle.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1-Figure 4 As shown, the utility model provides a protective device for an indwelling needle, including a wristband 2, a protective cover 1 is installed on the wristband 2, and is used to protect the indwelling needle. The protective cover 1 is composed of a left half shell 11 and a right half shell 12, and the left half shell 11 and the right half shell 12 are respectively fixed on the two ends of the wristband 2. A covering component 3 is installed below the protective cover 1 near the indwelling needle for dust prevention. A groove 111 is provided on the side wall of the left half shell 11, and a plurality of magnetic suction sheets 112 are installed in the groove 111. A plurality of iron sheets 121 are installed near the magnetic suction sheet 112 on the right half shell 12. The iron sheets 121 are inserted into the groove 111 and adsorbed with the magnetic suction sheets 112, so that the left half shell 11 and the right half shell 12 can be opened and closed, and the interior can be cleaned. The magnetic suction sheet 112 has a strong magnetic force, so that the iron sheet 121 and the magnetic suction sheet 112 can be tightly adsorbed together, and the left half shell 11 and the right half shell 12 will not be separated due to scratching.

[0025] Among them, the wristband 2 is made of elastic material and has elasticity; the connection between the left half shell 11 and the right half shell 12 and the wristband 2 can be bent, so that the left half shell 11 and the right half shell 1 can be rotated relative to the wristband 2, so that the left half shell 11 and the right half shell 1 that are closed together can be separated, which is convenient for the connection of the infusion tube and the connector on the indwelling needle during the patient's infusion.

[0026] In this embodiment, the protective cover 1 is a hemispherical structure with an internal cavity, and the left half shell 11 and the right half shell 12 are both quarter-spherical shell structures.

[0027] Specifically, a breathable mesh 21 is installed on the inner wall of the wristband 2 to improve the breathability of the wristband 2.

[0028] Furthermore, a plurality of ventilation holes 13 are provided on the outer wall of the protective cover 1 to improve the ventilation effect.

[0029] Furthermore, the covering assembly 3 includes a covering net 31, and fixing plates 32 are provided at both ends of the covering net 31. The fixing plates 32 are connected to the wristband 2 at the ends away from the covering net 31, and an opening 312 is provided in the middle of the covering net 31. The opening 312 is provided to allow the connector on the indwelling needle to extend out, so as to facilitate the connection of the infusion tube.

[0030] Furthermore, a slide groove 321 is provided on one side of the fixing plate 32 , a spring 322 is installed in the slide groove 321 , a slide plate 311 is installed at one end of the spring 322 , and one end of the slide plate 311 away from the spring 322 is connected to the side of the covering net 31 .

[0031] Furthermore, the wristband 2 is made of elastic fabric material to improve the adaptability of the wristband 2.

[0032] Furthermore, a sponge layer is attached to the inner wall of the protective cover 1 to absorb the water overflowing from the indwelling needle.

[0033] When the protective device for the indwelling needle of the utility model is used, after the indwelling needle is punctured on the patient's wrist, the wristband 2 is then put on the patient's wrist, and the tightness of the wristband 2 is adjusted according to the size of the wrist to ensure comfort and firmness. The wristband 2 is made of elastic cloth material, has good elasticity and air permeability, can adapt to the wrist sizes of different patients, and provide a comfortable wearing experience. At this time, the indwelling needle is retained inside the protective cover 1.

[0034] The protective cover 1 is composed of a left half shell 11 and a right half shell 12, which are connected by the adsorption of a magnetic sheet 112 and an iron sheet 121. This design facilitates the opening and closing of the left half shell 11 and the right half shell 12, and is convenient for medical staff to clean and disinfect the inside of the protective cover 1.

[0035] The covering net 31 of the covering assembly can cover the indwelling needle and its connecting tube, and can prevent the shaking of the connector on the indwelling needle. Meanwhile, the design of the covering net 31 also takes air permeability into consideration to ensure that the inside of the protective cover 1 will not be too stuffy.

[0036] During the use of the indwelling needle, if the patient needs to move his wrist or put on clothes, the protective cover 1 can effectively prevent the indwelling needle from directly contacting external objects, thereby reducing the risk of the needle falling off. At the same time, the cavity structure and the air vent 13 design inside the protective cover 1 ensure the natural state of the indwelling needle and its connecting tube, avoiding bending and compression.

[0037] When the patient needs infusion, the left half shell 11 and the right half shell 12 are opened, so that the left half shell 11 and the right half shell 12 are separated to expose the connector on the indwelling needle, and the connector on the indwelling needle can pass through the opening 312 to be exposed, and the infusion connector is connected to the connector on the indwelling needle to start infusion.

[0038] In addition, the inner wall of the protective cover 1 is pasted with a sponge layer, which can absorb the moisture that may overflow from the indwelling needle and keep the patient's skin dry and comfortable. This meticulous design takes into account the actual needs of patients and improves the quality of medical care and the comfort of patients.

[0039] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
