Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a special indwelling needle for patients with edema and exudate. Background Art

[0002] An intravenous catheter is an infusion tool, mainly composed of a stainless steel core, a soft outer sleeve and a plastic catheter seat. After puncture, only the soft outer sleeve is left in the blood vessel for infusion. It can be left in place for a long time and has the characteristics of easy operation, reduced number of punctures, and less stimulation to blood vessels. It has been widely used in clinical practice and has become an important way of clinical treatment, emergency medication and nutrition supply.

[0003] When edema patients receive infusions through indwelling needles, the puncture site becomes moist due to exudation in the skin, which makes it difficult to firmly fix the indwelling needle dressing and easy to fall off. Nursing staff have to frequently re-fix the indwelling needle, which not only increases their workload, but also brings unnecessary pain to patients. What is more serious is that the falling off of the indwelling needle dressing caused by exudation may cause the risk of slippage of the indwelling needle and local skin infection, which further affects the patient's disease treatment effect and clinical care effect. Repeated puncture operations not only increase the physical burden of patients, but may also reduce their confidence and cooperation in treatment, and have a negative impact on the overall treatment effect.

DETAILED DESCRIPTION

[0029] 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.

[0030] Combination Figure 1-Figure 4As shown, the utility model is a special indwelling needle for patients with edema and exudate, comprising a needle seat 1, a puncture needle 2 and an extension tube 3 which are arranged on the needle seat 1 and communicated with the needle seat 1.

[0031] The impermeable cover 4 is arranged outside the needle seat 1 and the puncture needle 2, and the side thereof facing the hand surface is opened;

[0032] The annular adhesive base plate 5 is arranged on the outer side of the impermeable cover 4, and an adhesive layer is also arranged on the side close to the hand surface, which is used to adhere to the hand surface to form a closed space between the impermeable cover 4 and the hand surface;

[0033] The exudate absorbent pad 6 is arranged on the inner side of the anti-seepage cover 4 and is used to absorb the edema exudate in the anti-seepage cover 4;

[0034] A flow guide pipe 7, one end of which is disposed on the side wall of the anti-seepage cover 4 and is connected to the anti-seepage cover 4;

[0035] The positive pressure sealed infusion connector 8 is arranged on the other end of the flow guide tube 7 .

[0036] Due to the technical means of adopting the anti-seepage cover 4 and the annular adhesive base 5, the anti-seepage cover 4 can be connected to the punctured hand surface through the annular adhesive base 5, and a closed area is formed between the anti-seepage cover 4 and the hand surface. The exudate of the edema patient can be absorbed by the exudate absorbent pad 6. When the exudate reaches a certain volume, the exudate in the anti-seepage cover 4 is extracted through the guide tube 7 and the positive pressure sealed infusion connector 8.

[0037] In a preferred embodiment, the present invention can be further configured as follows: Figure 3As shown; a semicircular notch 9 matching with the needle seat 1 is processed on the end of the side of the anti-seepage cover 4 facing the hand surface, and an elastic rubber sealing pad arranged in an arc shape is arranged in the semicircular notch 9, wherein the needle seat 1 is located on the inner side of the elastic rubber sealing pad, and after the indwelling needle is punctured and retained in the patient's body, the anti-seepage cover 4 is placed on the outer side of the needle seat 1 and the puncture needle 2 to cover and protect the puncture site, at this time, the semicircular notch 9 on the side of the anti-seepage cover 4 facing the hand surface matches with the needle seat 1, so that the needle seat can be just embedded in the notch, and then, the elastic rubber sealing pad in the semicircular notch 9 plays a key role, this sealing pad is arranged in an arc shape, and can fit tightly on the outer side of the needle seat 1 to form a sealed The interface, due to the flexibility and resilience of the elastic rubber, can ensure that even when the hand surface is slightly deformed due to edema, it can still maintain sealing and prevent exudate from overflowing from the interface. Through such a design, the interface between the impermeable cover 4 and the needle seat 1 is effectively sealed, further enhancing the airtightness of the entire indwelling needle system, which can not only prevent exudate from overflowing and keep the puncture site dry, but also reduce the possibility of external bacteria or contaminants entering, thereby reducing the risk of infection. In summary, the design of the semicircular groove on the impermeable cover and the elastic rubber sealing pad further improves the safety and effectiveness of the indwelling needle for patients with edema and exudate by enhancing the sealing of the interface.

[0038] In a preferred embodiment, the present invention can be further configured as follows: Figure 2 , Figure 4 As shown; the liquid-absorbing pad 6 comprises:

[0039] The hydrocolloid transparent medical dressing layer 61 is disposed inside the impermeable cover 4 and is in a circular shape as a whole; and

[0040] The puncture hole 62 is processed on the hydrocolloid transparent medical dressing layer 61, which can be used for the puncture needle 2 to pass through. The hydrocolloid transparent medical dressing layer 61 is the main part of the exudate absorbent pad and is arranged on the inner side of the impermeable cover 4. This hydrocolloid transparent medical dressing layer 61 has good water absorption performance and can quickly absorb the liquid exuded from the puncture site. It is arranged in a circular shape as a whole, which is adapted to the shape of the impermeable cover 4 to ensure that the puncture site can be covered and the exudate can be effectively absorbed. At the same time, in order not to hinder the normal use of the puncture needle, the hydrocolloid transparent medical dressing layer 61 is processed with a puncture hole 62. The size of this puncture hole is moderate, which can allow the puncture needle 2 to pass smoothly, while maintaining the sealing of the surrounding area to prevent Exudate overflows from the hole. During the infusion process, when exudate appears at the puncture site, the exudate will be quickly absorbed by the hydrocolloid transparent medical dressing layer 61. Due to the characteristics of the hydrocolloid material, it can effectively lock the exudate inside the dressing layer to prevent it from spreading to the surrounding area. At the same time, due to the sealing effect of the impermeable cover 4, the exudate is confined to the space between the impermeable cover 4 and the hydrocolloid transparent medical dressing layer 61 and will not overflow to the patient's body surface. Through this working principle, the exudate absorbent pad 6 can effectively absorb and manage the exudate at the puncture site, keep the puncture site dry and clean, and reduce the risk of infection. At the same time, it can also reduce the workload of nursing staff and reduce the inconvenience caused by frequent replacement of dressings.

[0041] In a preferred embodiment, the present invention can be further configured as follows: Figure 4 As shown; the diameter of the hydrocolloid transparent medical dressing layer 61 is smaller than the diameter of the impermeable cover 4, and the diameter of the annular adhesive bottom plate 5 is larger than the diameter of the impermeable cover 4. The hydrocolloid transparent medical dressing layer 61 is the core part of the exudate absorbent pad 6, and its diameter is smaller than the diameter of the impermeable cover 4, which means that it can fit tightly around the puncture site without exceeding the range of the impermeable cover 4. This design ensures that the exudate absorbent pad 6 can effectively absorb the liquid exuded from the puncture site and lock it inside the dressing layer to prevent the exudate from spreading. Secondly, the diameter of the annular adhesive bottom plate 5 is larger than the diameter of the impermeable cover 4, so that the bottom plate can be more widely attached to the patient's hand surface. This design not only enhances the overall stability of the indwelling needle and prevents it from falling off due to patient activities or external forces, but also ensures that a more closed space is formed between the impermeable cover and the hand surface. Through the viscosity of the bottom plate, the impermeable cover can fit tightly on the skin surface to prevent the exudate from overflowing from the edge.

[0042] In a preferred embodiment, the present invention can be further configured as follows: Figure 1 , Figure 2As shown; a light-proof tube 10 is sleeved on the outer side of the extension tube 3, wherein the diameter of the light-proof tube 10 is larger than the diameter of the extension tube 3, and the diameter of the light-proof tube 10 is adapted to the diameter of the extension tube 3. The main function of the light-proof tube 10 is to provide light-proof protection for the infusion content in the extension tube. For certain infusion drugs that need to be protected from light, such as photosensitive drugs, long-term exposure to sunlight or strong light may cause the drugs to become ineffective or produce adverse reactions. Therefore, the existence of the light-proof tube 10 can effectively isolate external light and ensure the stability and safety of the infusion drugs during the transportation process. Secondly, the diameter adaptation design between the light-proof tube and the extension tube ensures a close fit between the two. The diameter of the light-proof tube 10 is slightly larger than that of the extension tube. The diameter of the long tube allows the light-shielding tube to be easily mounted on the outside of the extension tube without being too loose or too tight. This adaptation design not only ensures a firm connection between the light-shielding tube 10 and the extension tube 3, preventing it from falling off or shifting due to external force during the infusion process, but also ensures a smooth infusion process, avoiding infusion interruptions or abnormal flow rates caused by pipeline connection problems. In addition, the light-shielding tube is usually made of a material with light-shielding properties, such as black or dark-colored opaque materials. This material can effectively absorb or reflect external light and reduce the impact of light on infused drugs. At the same time, the light-shielding tube should also have a certain degree of flexibility and durability to adapt to changes in the patient's body position and the length of infusion time.

[0043] The specific working principle of the indwelling needle specially used for patients with edema and exudate is as follows:

[0044] First, the indwelling needle for patients with edema and exudate is used to puncture the skin through the puncture needle 2 on its needle holder 1 and is retained in the patient's body for infusion treatment. At this time, the anti-seepage cover 4 arranged on the outside of the needle holder 1 and the puncture needle 2 plays a key role. The side facing the hand surface is open, which can cover and protect the puncture site to prevent exudate from overflowing. The outer side of the anti-seepage cover 4 is provided with an annular adhesive base plate 5, and the side close to the hand surface is provided with an adhesive layer, which is used to stick the anti-seepage cover 4 tightly to the patient's hand surface to form an enclosed space. In this way, the exudate is effectively confined in the anti-seepage cover 4 and will not spread to areas outside the puncture site. On the inner side of the anti-seepage cover 4, an exudate absorbent pad 6 is provided to absorb the edema exudate in the anti-seepage cover. The hydrocolloid transparent medical dressing layer 61 has good water absorption performance and can quickly absorb the liquid exuded from the puncture site to keep the exudate. The puncture site is kept dry, thereby preventing the risk of the indwelling needle dressing falling off and infection caused by exudate. When the exudate absorbed by the exudate absorbent pad reaches a certain volume, the syringe draws back the skin exudate through the guide tube 7 arranged on the side wall of the impermeable cover 4, reducing the accumulation of exudate on the skin surface. The exudate can be discharged to an external collection device. In this way, it is avoided that the exudate accumulates too much in the impermeable cover and affects the use effect of the indwelling needle. In addition, the other end of the guide tube 7 is provided with a positive pressure sealed infusion connector 8, which can keep the guide tube 7 unobstructed and prevent external bacteria or contaminants from entering the impermeable cover, ensuring the safety and hygiene of the infusion process. Finally, a light-proof tube 10 is provided on the outer side of the extension tube 3 of the indwelling needle to protect the infusion pipeline from interference from external light, especially for some infusion drugs that need to be protected from light. The use of a light-proof tube can ensure the effectiveness and safety of the drugs.

[0045] In summary, the patented dedicated indwelling needle for patients with edema and exudate achieves effective management and control of exudate through the synergistic effect of its unique anti-seepage cover, annular sticky base, exudate absorbent pad, diversion tube, positive pressure sealed infusion connector, light-proof tube and other components, providing patients with edema and exudate with a safer and more effective infusion treatment plan.
