Description

Technical Field

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

[0002] The prior art discloses an infusion protection device, including a transparent protective cover, a medical elastic bandage and a Velcro. The transparent protective cover is located above the medical elastic bandage and is connected to the medical elastic bandage at the edge of the transparent protective cover. The transparent protective cover is provided with a plurality of air holes. The medical elastic bandage is connected to the Velcro. The two ends of the medical elastic bandage are respectively connected to the fur surface and the thorn surface of the Velcro. A circular hole is provided at one section of the medical elastic bandage for inserting a finger to position the infusion protection device. By covering the infusion protection device on the infusion needle patch, the sanitation and safety of the infusion needle and the infusion needle area are protected, and the infusion status of the infusion needle patch in the infusion area can be seen through the transparent observation window, protecting the infusion needle and the needle tube in the infusion area from external infection, and protecting the infusion accidents such as rolling needle caused by surrounding collision during the infusion process. The following disadvantages exist:

[0003] First, the medical elastic bandage of the infusion protection device has no ventilation holes, which causes skin allergies and other skin problems in patients;

[0004] Secondly, the purpose of the infusion protection device is to protect the infusion needle and the needle tube connector from being easily interfered with and contaminated by the surrounding environment and objects, and to protect the infusion safety of the infusion needle and the needle tube connector. However, the transparent protective cover is a single-opening or double-opening structure, and its opening itself is also easily interfered with by the outside world. In addition, the infusion needle and the needle tube connector in the transparent protective cover are only fixed by medical tape, and the fixing effect is poor. When the catheter connected to the infusion needle and the needle tube connector is slightly pulled by the outside, the infusion needle and the needle tube connector in the transparent protective cover will easily break away from the fixation of the medical tape. Utility Model Content

[0005] In view of the above problems, the utility model provides an indwelling needle protective cover with better air permeability and better fixing effect.

[0006] The technical solution of the utility model is: an indwelling needle protective cover, comprising a base, a transparent protective cover and a Velcro, wherein the base is in a long strip shape, and an observation port for observing the indwelling needle is provided on the base, and a transparent protective cover is provided on the observation port, and a plurality of air holes are provided on the surface of the base. By providing a plurality of air holes on the surface of the base, the ventilation effect of the indwelling needle protective cover is enhanced, and skin problems such as skin allergies of patients are avoided.

[0007] In a further technical solution, the diameter of the air holes is 2 mm to 6 mm, for example, 2 mm, 3 mm, 4 mm, or 5 mm.

[0008] In a further technical solution, the transparent protective cover has a receiving cavity for receiving the indwelling needle and having an opening on the bottom surface, and at least one avoidance notch is provided on the edge of the opening on the bottom surface of the receiving cavity. The opening of the avoidance notch faces the width direction of the base; the base is an elastic bandage, and the part of the elastic bandage directly below the avoidance notch serves as a crimping part for pressing and fixing the catheter of the indwelling needle. On the basis of the traditional fixation of the indwelling needle, the catheter of the indwelling needle is fixed by the combination of the crimping part and the avoidance notch, so as to further improve the fixing effect of the entire indwelling needle.

[0009] In a further technical solution, the surface of the crimping part close to the patient's skin is provided with a wavy anti-skid protrusion. The design of the anti-skid protrusion further increases the friction between the crimping part and the catheter of the indwelling needle, further improving the fixing effect of the entire indwelling needle.

[0010] In a further technical solution, the base is bonded with a Velcro tape extending along the length direction of the base at the two sides of the transparent protective cover, and the two Velcro tapes are respectively located on the front and back sides of the base. The detachable connection of the Velcro tape improves the practicality of the indwelling needle protective cover and makes the operation easier.

[0011] In a further technical solution, the Velcro is provided with a through hole matching the air hole of the base. The design of providing the through hole on the Velcro can avoid the Velcro covering the base and affecting the air permeability of the entire indwelling needle protective sleeve.

[0012] In a further technical solution, the base is provided with a thumb-through slit at the two sides of the transparent protective cover, and the thumb-through slit is located on the upper or lower side of the Velcro, and the length of the thumb-through slit is 10 mm to 20 mm, and the width is 0.5 mm to 3 mm. Through the design of the thumb-through slit, the protective cover of the indwelling needle is further fixed on the basis of the Velcro to prevent it from moving.

[0013] In a further technical solution, the indwelling needle protective cover also includes an anti-slip belt, and the two ends of the anti-slip belt are detachably connected to the parts of the base located on both sides of the transparent protective cover. The design of the anti-slip belt is mainly used in the case of head fixation. Due to individual differences among patients, in order to prevent the indwelling needle protective cover from accidentally slipping off when applied to the head, an anti-slip belt is added, and the anti-slip belt can be freely and easily removed. That is, the anti-slip belt can be connected to the elastic bandage through Velcro (buckle). The specific use is to first tie the elastic bandage to the patient's head, and then pass the anti-slip belt from one side of the patient around the chin and then stick it on the other side to prevent the elastic bandage from sliding up. On the contrary, passing the anti-slip belt around the top of the head can prevent the elastic bandage from sliding down. Use a strip of anti-slip belt to pass around the chin and the top of the head, or use two anti-slip belts, so that one anti-slip belt passes around the chin and the other anti-slip belt passes around the top of the head.

[0014] In a further technical solution, the thickness of the base is 0.5 mm to 1.5 mm. The thickness of the base is designed mainly to enhance the tensile strength of the base itself. For patients with high fixation requirements, a thicker base of 1, 2 mm, or 1.5 mm is used; for patients with low fixation requirements, a thinner base of 0.5 mm or 0.8 mm is used.

[0015] The beneficial effects of the utility model are:

[0016] 1. By opening a plurality of air holes on the surface of the base, the air permeability of the protective cover of the indwelling needle is enhanced to avoid skin problems such as skin allergies in patients.

[0017] 2. On the basis of the traditional fixation of the indwelling needle, the catheter of the indwelling needle is fixed by cooperating the crimping part with the avoidance notch to further improve the fixation effect of the entire indwelling needle.

[0018] 3. The anti-slip protrusion design further improves the friction between the crimping part and the catheter of the indwelling needle, further improving the fixing effect of the entire indwelling needle.

[0019] 4. The detachable connection of Velcro improves the practicality of the indwelling needle protective cover and makes the operation easier.

[0020] 5. The design of opening a through hole on the Velcro can prevent the Velcro from covering the base and affecting the breathability of the entire indwelling needle protective cover.

[0021] 6. Through the design of the thumb-through seam, on the basis of the fixation of Velcro, the protective cover of the indwelling needle is further improved to prevent it from moving.

[0022] 7. The anti-slip belt is mainly used in the case of head fixation. Due to individual differences among patients, an anti-slip belt is added to prevent the indwelling needle protective cover from accidentally slipping off when applied to the head. The anti-slip belt can be easily removed. That is, the anti-slip belt can be connected to the elastic bandage through Velcro (buckle). The specific use is to first tie the elastic bandage to the patient's head, and then pass the anti-slip belt from one side of the patient around the chin and then stick it on the other side to prevent the elastic bandage from sliding up.

[0032] The embodiments of the present utility model will be further described below in conjunction with the accompanying drawings.

[0033] Embodiment 1:

[0034] like Figure 1-6 As shown, a protective cover for an indwelling needle comprises a base 1, a transparent protective cover 2 and a Velcro 3. The base 1 is in the shape of an elongated strip, and is provided with an observation port 11 for observing the indwelling needle. The transparent protective cover 2 is provided on the observation port 11, and a plurality of air holes are provided on the surface of the base 1. Among them, a plurality of small air holes 21 are provided on the transparent protective cover 2. The transparent protective cover 2 can be located in the middle of the entire base 1, or can be biased towards the entire base 1. By providing a plurality of air holes on the surface of the base 1, the ventilation effect of the protective cover for the indwelling needle is enhanced, and skin problems such as skin allergies of patients are avoided.

[0035] In another embodiment, the diameter of the air holes is 2 mm to 6 mm, for example, 2 mm, 4 mm, or 6 mm.

[0036] In another embodiment, the transparent protective cover 2 has a receiving cavity for receiving the indwelling needle and having an opening on the bottom. The bottom opening of the receiving cavity is attached to and fixed to the observation port 11 of the base 1. At least one avoidance notch 22 is provided on the edge of the bottom opening of the receiving cavity (the avoidance notch 22 is a semicircular opening, and the specific size is actually determined according to the diameter of the catheter of the indwelling tube and the thickness of the base 1). The opening of the avoidance notch 22 faces the width direction of the base 1; the base 1 is an elastic bandage, and the part of the elastic bandage directly below the avoidance notch 22 serves as a crimping portion 111 for pressing and fixing the catheter of the indwelling needle. On the basis of the traditional fixation of the indwelling needle, the catheter of the indwelling needle is fixed by cooperating with the crimping portion 111 and the avoidance notch 22, so as to further improve the fixing effect of the entire indwelling needle.

[0037] In another embodiment, the surface of the crimping portion 111 close to the patient's skin is provided with a wavy anti-skid protrusion. The anti-skid protrusion design further increases the friction between the crimping portion 111 and the catheter of the indwelling needle, further improving the fixing effect of the entire indwelling needle.

[0038] In another embodiment, the base 1 is bonded with two Velcro strips 3 extending along the length direction of the base 1 on the two sides of the transparent protective cover 2, and the two Velcro strips 3 are respectively located on the front and back sides of the base 1. The detachable connection of the Velcro strips 3 improves the practicality of the indwelling needle protective cover and makes the operation easier.

[0039] In another embodiment, the Velcro 3 is provided with a through hole matching the vent hole of the base 1. By designing the through hole on the Velcro 3, it is prevented that the Velcro 3 covers the base 1 and affects the ventilation performance of the entire indwelling needle protective cover.

[0040] In another embodiment, the base 1 is provided with a thumb-through slit 12 at the two sides of the transparent protective cover 2, and the thumb-through slit 12 is located on the upper or lower side of the Velcro 3, and the slit length of the thumb-through slit 12 is 10 mm to 20 mm, and the width is 0.5 mm to 3 mm. For example, the slit length of the thumb-through slit 12 is 15 mm, and the width is 1.5 mm, or the slit length of the thumb-through slit 12 is 10 mm, and the width is 0.5 mm. Through the design of the thumb-through slit 12, on the basis of the fixation of the Velcro 3, the fixation of the indwelling needle protective cover is further improved to prevent it from moving.

[0041] In another embodiment, the indwelling needle protective cover also includes an anti-slip belt 4, and the two ends of the anti-slip belt 4 are detachably connected to the parts of the base 1 located on both sides of the transparent protective cover 2. The design of the anti-slip belt 4 is mainly used in the case of head fixation. Due to individual differences among patients, in order to prevent the indwelling needle protective cover from accidentally slipping off when applied to the head, an anti-slip belt 4 is added, and the anti-slip belt 4 can be freely and easily removed. That is, the anti-slip belt 4 can be connected to the elastic bandage through Velcro 3 (buckle). The specific use is to first tie the elastic bandage to the patient's head, and then put the anti-slip belt 4 from one side of the patient around the chin and then stick it on the other side to prevent the elastic bandage from sliding up. On the contrary, if the anti-slip belt 4 is passed around the top of the head, the elastic bandage can be prevented from sliding down. Use a strip of anti-slip belt 4 to pass around both the chin and the top of the head, or use two anti-slip belts 4, so that one anti-slip belt 4 passes around the chin and the other anti-slip belt 4 passes around the top of the head.

[0042] In another embodiment, the thickness of the base 1 is 0.5 mm to 1.5 mm. The thickness design of the base 1 is mainly based on enhancing the tensile strength of the base 1 itself. For patients with high fixation requirements, a thicker base 1 of 1.2 mm or 1.5 mm is used; for patients with low fixation requirements, a thinner base 1 of 0.5 mm or 0.8 mm is used.

[0043] When in use, first, the nurse fixes the indwelling needle on the back of the patient's hand (depending on the actual situation of the patient's injection, different positions on the patient's body are selected, such as the head, back of the hand, palm, arm or leg). Then, the nurse covers the transparent protective cover 2 of the indwelling needle protective cover at the corresponding position of the indwelling needle. The part of the elastic bandage on one side of the transparent protective cover 2 is passed around the back of the hand and bonded to the part of the elastic bandage on the other side of the transparent protective cover 2 to form a ring-shaped fixation. At the same time, the catheter of the indwelling needle is pressed on the back of the hand by the crimping part 111 in a tightened state (after the elastic bandage is fixed in a ring shape, the crimping part 111 will naturally be tightened). The catheter of the indwelling needle will reversely push up the crimping part 111, so that the crimping part 111 protrudes in the direction away from the patient's skin, and the protruding part is just located at the avoidance gap 22.

[0044] The above-mentioned embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
