Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and specifically relates to a closed protective box for hemodialysis tubes. Background Technique

[0002] The hemodialysis tube is an important blood passage for patients during hemodialysis. Through this passage, the patient's blood can be drawn out of the body, purified by the dialyzer, and then safely returned to the body, thus ensuring the smooth flow of blood in and out of the dialyzer to complete the entire dialysis process.

[0003] However, in various emergency situations, such as acute kidney injury requiring immediate hemodialysis, or chronic renal failure patients requiring emergency dialysis due to complications such as heart failure, pulmonary edema, severe electrolyte disorders, uremic encephalopathy, etc., it is necessary to quickly establish and immediately use a vascular access. Since the hemodialysis tube needs to be indwelled in the patient's body for a long time and has a Y-shaped structure, including a main tube and two branch tubes, how to properly fix the hemodialysis tube has become a key issue. Currently, medical staff usually simply wrap and fix the tube of the hemodialysis tube with gauze, but this method has obvious limitations, that is, it is difficult to provide an effective waterproof function. When the patient takes a bath, due to the penetration of water, the wrapped gauze may get wet, which will increase the risk of infection and cause complications. This not only brings physical discomfort to the patient, but also increases the difficulty and complexity of medical care. Therefore, the hemodialysis tube does cause many inconveniences when the patient takes a bath, and there is an urgent need for a more effective and convenient fixing and protection method to ensure the safety and comfort of the patient.

[0004] On the Chinese Patent Network, a utility model patent with an authorization announcement number of CN220070307 and an authorization announcement date of November 24, 2023, discloses a closed protective bag for hemodialysis tubes. Although this patent can prevent infection complications caused by the entry of water into the hemodialysis tube to a certain extent, it still has significant deficiencies. Specifically, a large area of dressing is directly pasted on the patient's skin, which not only brings a strong foreign body sensation to the patient, but also increases the tediousness of cleaning the paste residue. In addition, considering the tension characteristics of the human skin, especially in the application scenario of a long-term catheter in the jugular vein, the outlet of which is located on the subspinous muscle 2-3 cm from the midclavicular line on the right side of the human body, and since most people are used to using their right hand, the activities of the right hand during bathing may cause a large range of stretching of the subspinous muscle, which will seriously affect the adhesion of the dressing. Coupled with the direct impact of the shower head, the dressing is extremely easy to fall off or partially fail, resulting in the protective belt not being tightly sealed, which will increase the risk of water entering the hemodialysis tube and infection.

[0005] In view of the above problems, we hereby propose a closed protective box for hemodialysis tubes with good sealing performance and convenient use, aiming to fundamentally solve the above technical problems, improve the patient's use experience and reduce the risk of infection.
