Description

Technical Field

[0001] This utility model relates to the field of indwelling needle protection technology, and in particular to an indwelling needle protective cover. Background Technology

[0002] An indwelling catheter, also known as a peripheral intravenous catheter or venous catheter, is a common medical device used for short-term intravenous infusion, medication administration, or blood collection. Compared to ordinary steel needles, the advantage of an indwelling catheter is that it can remain in the blood vessel for several days, reducing the pain and damage caused by repeated punctures. Because of this advantage, patients need to be careful to prevent the indwelling catheter from getting wet during daily activities such as washing and grooming, which could lead to inflammation.

[0003] To prevent water from entering, clinical staff directly use large waterproof tape to stick to the patient's skin to wrap the entire indwelling needle. Although the waterproof tape can achieve a waterproof effect, because the waterproof tape has a large area and a large contact area with the patient's skin, medical staff can easily pull on the indwelling needle when tearing and changing the waterproof tape, causing the indwelling needle to shift.

[0004] Therefore, there is an urgent need to develop a protective cover for indwelling needles that is both waterproof and reduces the area of ​​contact with the patient's skin. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a protective cover for indwelling needles, which can reduce the adhesion area with the patient's skin while satisfying waterproofing, and can also use tape to fix the indwelling needle separately, so as to prevent the bottom ring from pulling the indwelling needle during disassembly and affecting the insertion position of the indwelling needle.

[0006] This utility model provides a protective cover for an indwelling needle, including a bottom ring that is adhered to the skin around the indwelling needle, a top ring that is detachably connected to the top of the bottom ring, and a transparent water-blocking cover that is fixed inside the top ring. The water-blocking cover covers the outside of the indwelling needle for waterproofing.

[0007] The bottom ring has multiple strips of tape inside for fixing the indwelling needle. Both ends of the tape are processed with tear lines, so that medical staff can tear the tape along the tear lines when removing the bottom ring.

[0008] In one embodiment, the bottom ring includes a bottom plate, a retaining strip is fixed to the top of the bottom plate, and an adhesive layer is adhered to the bottom of the bottom plate, the bottom plate being adhered to the skin through the adhesive layer;

[0009] The top ring includes a top plate a and a top plate b fixed to the bottom of the water baffle. The bottom of the top plate a and the bottom of the top plate b are both provided with slots for accommodating the card strip. The bottom plate is inserted into the slots to connect the bottom plate with the top plate a and the top plate b.

[0010] In one embodiment, a release paper ring is adhered to the bottom of the adhesive layer, and a release paper strip is adhered to the bottom of each tape. The release paper ring and release paper strip can prevent external substances from sticking to the adhesive layer and tape and affecting their adhesion.

[0011] In one embodiment, a support member is movably connected to the top of the top plate b. The support member supports the water shield into a hemispherical shape, so that there is a certain space between the top of the inside of the water shield and the indwelling needle. On the one hand, this can avoid squeezing the indwelling needle, and on the other hand, it can facilitate the skin ventilation at the puncture site of the indwelling needle, thus improving comfort.

[0012] In one embodiment, the support includes two support plates, which are respectively fixed to the top of the top plate b at both ends near the top plate a. Multiple ribs are connected between the two support plates, and the multiple ribs are fixed at equal intervals to the outer wall of the water shield.

[0013] One of the ribs is fixed to the side walls of the two support plates at both ends, and the remaining ribs are fixed to the end of the limit protrusions. The two support plates are provided with limit grooves for the limit protrusions to slide. By sliding multiple ribs toward the top plate b, the water shield can be folded to facilitate the storage of the top ring and water shield in environments where waterproofing is not required.

[0014] In one embodiment, a tube end limiting seat for accommodating an indwelling needle infusion tube is fixed in the middle of the side of the top plate a away from the top plate b. A sealing ring is fixed on the inner wall of the tube end limiting seat. After the water shield covers the outside of the indwelling needle, the sealing ring is locked outside the indwelling needle infusion tube.

[0015] In one embodiment, the two ends of the base plate are processed into an upwardly bent shape, and the shape of the adhesive layer is consistent with the shape of the base plate, which is used to bond the outer wall of the indwelling needle infusion tube and fix it to the patient's skin.

[0016] In one embodiment, the locking strip is processed into a shape that is larger at the top and smaller at the bottom to prevent water from entering the interior of the water-blocking cover from the locking groove. The bottom plate and the top plate a are both made of elastic material, which is the same material as the bottom plate of the medical ostomy bag. It is not only waterproof but also elastic, which can easily stretch the top plate a to deform during installation, so that the locking strip can be smoothly inserted into the interior of the top plate a to complete the installation.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. By setting a hemispherical water-blocking cover to waterproof the indwelling needle site during the patient's washing process, and using an annular bottom ring to fix the water-blocking cover to the outer periphery of the indwelling needle, and using tape to fix the indwelling needle to the patient's skin, this invention can reduce the contact area between the device and the patient's skin while ensuring waterproofing, achieving two goals at once.

[0019] 2. By using a support to hold the water shield above the indwelling needle, the water shield is suspended above the indwelling needle to facilitate ventilation and improve the comfort of the indwelling needle puncture site. At the same time, the support also helps to prevent foreign objects from squeezing the indwelling needle, thus protecting the indwelling needle. The support is also designed to be foldable, so that the water shield can be folded down when not in use for easy storage.

[0020] 3. This utility model adopts a snap-fit ​​method with clips and slots to achieve a detachable connection between the water baffle and the bottom ring, so that the top ring and the water baffle can be reused after disinfection treatment, thus enhancing practicality.

[0021] 4. This utility model has tear lines processed at both ends of each tape to facilitate medical staff to easily tear the tape when removing the bottom ring. This allows the bottom ring to be replaced separately without affecting the position of the indwelling needle, thus ensuring that the position of the indwelling needle is not affected.

[0034] The specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some, not all, of the embodiments of this utility model. Based on the description of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

[0035] like Figure 1-2 As shown, the present invention proposes an indwelling needle protective cover, including a bottom ring 1 that is adhered to the skin around the indwelling needle. Inside the bottom ring 1, there are multiple adhesive tapes 6 for fixing the indwelling needle. Each adhesive tape 6 has a release paper strip 7 adhered to its bottom. In use, the release paper strip 7 at the bottom of the adhesive tape 6 is first peeled off. Then, the multiple adhesive tapes 6 are respectively aligned with the first, middle and last sections of the indwelling needle. The indwelling needle is then adhered to the patient's skin using the adhesive tapes 6 to fix the indwelling needle. Then, the bottom ring 1 is adhered to the skin around the indwelling needle. A top ring 2 is detachably connected to the top of the bottom ring 1. A transparent water-blocking cover 3 is fixed inside the top ring 2. The water-blocking cover 3 is placed over the indwelling needle for waterproofing, so as to prevent the puncture site of the indwelling needle from accidentally coming into contact with water when the patient is bathing or washing their face, thus achieving a waterproof effect.

[0036] In this embodiment, the structure of the bottom ring 1 is as follows: Figure 3 and Figure 4 As shown: It includes a base plate 11, with an adhesive layer 4 bonded to the bottom of the base plate 11, and a release paper ring 5 bonded to the bottom of the adhesive layer 4. In use, the release paper ring 5 is peeled off from the bottom of the adhesive layer 4, and then the base plate 11 is bonded to the skin around the indwelling needle using the adhesive layer 4. Compared with the clinical method of wrapping the indwelling needle with a large waterproof tape, the bonding area between the adhesive layer 4 and the tape 6 and the skin in this utility model is much smaller than the bonding area between the waterproof tape and the patient. In this utility model, the exposed skin area around the puncture site of the indwelling needle is larger, which facilitates skin ventilation and improves the comfort of using the indwelling needle.

[0037] It is known that indwelling needles only require protection from water during patient washing. However, existing waterproof tape used in clinical practice remains adhered to the patient's skin, resulting in poor breathability of the skin covered by the tape. To solve this problem, this invention specifically designs a detachable connection between the bottom ring 1 and the top ring 2, as shown in the specific structure below. Figure 3 and Figure 5As shown: A retaining strip 12 is fixed to the top of the base plate 11. The top ring 2 includes a top plate a21 and a top plate b26 fixed to the bottom of the water-retaining cover 3. The bottom of the top plate a21 and the bottom of the top plate b26 are both provided with slots 22 for accommodating the retaining strip 12. Before bonding the base plate 11, the retaining strip 12 can be inserted into the slots 22 to complete the connection between the base ring 1 and the top ring 2. Moreover, the retaining strip 12 is processed into a shape that is larger at the top and smaller at the bottom. This design can prevent water from entering the interior of the water-retaining cover 3 from the slots 22, thereby improving waterproofing. The inner cavity shape of the slot 22 is consistent with the shape of the strip 12, that is, the bottom opening of the slot 22 is small and the top opening is large. To facilitate the insertion of the strip 12 into the slot 22, both the bottom plate 11 and the top plate a21 in this invention are made of elastic material. Medical staff can insert the strip 12 into the slot 22 along the bottom opening (similar to the installation method between the ostomy bag base plate and the ostomy bag body in clinical practice, which can achieve detachable installation while achieving a waterproof effect). After the top ring 2 is installed on the bottom ring 1, the bottom ring 1 is then glued to the skin around the indwelling needle. When waterproofing is not required, the top ring 2 and the water-retaining cover 3 can be removed from the top of the bottom ring 1, allowing the skin around the indwelling needle to be directly exposed to the air, further improving its breathability and comfort.

[0038] In this embodiment, a tube end limiting seat 23 for accommodating the indwelling needle infusion tube is fixed in the middle of the side of the top plate a21 away from the top plate b26. A sealing ring 24 is fixed on the inner wall of the tube end limiting seat 23. After the water shield 3 covers the outside of the indwelling needle, the sealing ring 24 is locked outside the indwelling needle infusion tube. This arrangement is beneficial for fixing the position of the indwelling needle. The two ends of the bottom plate 11 are also processed into an upwardly bent shape. The shape of the adhesive layer 4 is consistent with the shape of the bottom plate 11 and is used to bond the outer wall of the indwelling needle infusion tube to fix it to the patient's skin. At the same time, it can also prevent water from entering from the gap between the indwelling needle infusion tube and the tube end limiting seat 23, thereby improving the waterproof effect.

[0039] Next, to facilitate the storage of the disassembled water shield 3, such as... Figure 3 , Figure 5 and Figure 6 As shown, a support member 25 is movably connected to the top of the top plate b26. The support member 25 supports the water shield 3 into a hemispherical shape. The water shield 3 itself is made of transparent and waterproof film material, which allows medical staff to easily observe the condition of the indwelling needle through the water shield 3. At the same time, the hemispherical water shield 3 also helps to keep the top of the indwelling needle suspended, preventing the indwelling needle from being squeezed and causing discomfort to the patient. It also allows the skin around the indwelling needle to breathe.

[0040] In this embodiment, the specific structure of the support member 25 includes: two support plates 251, which are respectively fixed to the top of the top plate b26 near the two ends of the top plate a21. Multiple ribs 252 are connected between the two support plates 251. The ribs 252 are fixed to the outer wall of the water shield 3. The ribs 252 can support the water shield 3 to make it hemispherical, and at the same time can prevent foreign objects from directly hitting or pressing the indwelling needle, thereby protecting the indwelling needle.

[0041] Of the multiple ribs 252 provided, one rib 252 is fixed at both ends to the side walls of two support plates 251, and the remaining ribs 252 are fixed at both ends to limit protrusions 253. Each of the two support plates 251 has a limiting groove 254 for sliding the limiting protrusions 253. When the water shield 3 is not in use, multiple unfixed ribs 252 can slide along the limiting groove 254 towards the top plate b26 until the multiple ribs 252 are moved to the desired position. Figure 5 The position shown allows the water shield 3 to be folded for easy storage when not in use.

[0042] Because the adhesive layer 4 at the bottom of the base plate 11 has a limited lifespan, it may lose its adhesiveness after a period of use. Therefore, medical staff need to replace the base ring 1 regularly. To prevent the indwelling needle from being pulled during the disassembly of the base ring 1, such as... Figure 4 As shown: Both ends of the tape 6 are processed with tear lines. When medical staff remove the bottom ring 1, they can tear the tape 6 along the tear lines, which makes it convenient for medical staff to remove the bottom ring 1 separately for replacement. The remaining tape 6 can still fix the indwelling needle to prevent the removal of the bottom ring 1 from affecting the position of the indwelling needle.

[0043] It is worth noting that the detachable design between the bottom ring 1, the top ring 2, and the water shield 3 means that the bottom ring 1 and the tape 6, which come into direct contact with the patient, can be used as disposable consumables, while the top ring 2 and the water shield 3 can be reused after cleaning and disinfection, thus improving the practicality of this utility model.

[0044] The specifications and sizes of this invention vary depending on the puncture site of the indwelling needle. This design allows the invention to be suitable for indwelling needles in different locations, such as the back of the hand, arm, and head of a child. It can also be used for adults and children, thus protecting indwelling needles of different sizes.

[0045] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
