Description

Technical Field

[0001] The utility model relates to the technical field of sinus tract angiography, in particular to a closed pressure ring. Background Art

[0002] The incidence of various types of chronic refractory wounds has increased year by year. As a special type of chronic wounds, sinus (cavity) type chronic wounds have also shown an upward trend in outpatient admissions in recent years. Most of them are caused by deep tissue infection and necrosis, and there is only one blind tube opening to the body surface, which can easily lead to incomplete removal of necrotic tissue and poor drainage, which causes fibrosis of the sinus (cavity) wall, leading to repeated wound infection, bacterial film formation, and prolonged wound healing. In addition, the main characteristics of the wound are that it is difficult to accurately judge the nature of the wound and the internal space structure, which has become a more difficult problem in this field.

[0003] To diagnose sinus (cavity) wounds, the invisible sinus wounds must first be made visible, and the diameter of the sinus opening, the anatomical relationship between the lesion and the surrounding local tissues must be determined. In clinical practice, sinus angiography is often used to understand the depth, direction, presence of branches or foreign bodies, and the relationship between the sinus and the surrounding tissues.

[0004] At present, the most widely used technology is traditional sinus angiography. However, in clinical applications, it is found that the contrast agent is very likely to overflow during injection because the sinus opening is too large or too small to fit tightly with the syringe. At the same time, pressurized injection cannot be performed and the entire length of the deeper, longer, and thinner sinus tracts (cavities) cannot be displayed, thus affecting the patient's diagnosis and treatment progress.

[0005] Therefore, a closed pressure ring is needed to solve the above problems. Summary of the invention

[0006] In order to solve the above problems, the utility model aims to provide a closed pressure ring, which can make the sinus opening and the syringe tightly combined, avoid leakage of contrast fluid during sinus tract angiography, and improve the whole-course imaging rate of sinus tract angiography lesions.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A closed pressurizing ring comprises a closed ring, Velcro buckles symmetrically arranged on both sides of the closed ring, and a fixing belt for connecting the two sets of Velcro buckles; the closed ring is provided with a through hole adapted to a syringe, and the closed ring is symmetrically provided with through grooves adapted to the Velcro buckles on both sides, one end of the Velcro buckle passes through one side of the through groove and is bonded to the other side of the Velcro buckle; the Velcro buckle is fixedly connected to the fixing belt.

[0009] More preferably, a cotton layer is fixedly connected to the inner surface of the fixing belt.

[0010] Preferably, a ring groove is provided at the through hole on the outer surface of the closed ring, a circular ring is clamped in the ring groove, the circular ring is fixedly connected to the fixing ring via a connecting ring, the side wall of the fixing ring is in close contact with the inner wall of the through hole and is flush with the inner surface of the closed ring on the side away from the connecting ring.

[0011] More preferably, the top and bottom of the annular groove are symmetrically provided with clamping grooves, and the top and bottom of the circular ring are fixedly connected with elastic rings, the diameter of the elastic ring is larger than the annular groove and is adapted to the clamping grooves.

[0012] More preferably, one end of the Velcro buckle is fixedly connected with a buckle, and the other end of the Velcro is provided with multiple groups of through slots, and the buckle is adapted to the through slots.

[0013] More preferably, a first rubber layer is provided on the inner surface of the closed ring, and a second rubber layer is provided on the inner surface of the fixed ring.

[0014] More preferably, an elastic layer is fixed to the inner wall of the through groove.

[0015] The utility model has the following beneficial effects:

[0016] 1. The utility model can make the syringe and the through hole of the closed ring fit tightly together through the cooperation between the closed ring, the Velcro buckle and the fixing belt, so as to form a sealed space between the sinus opening and the film, increase the resistance of the contrast agent to overflow from the sinus opening, reduce the overflow of the contrast agent, increase the success rate of the contrast agent entering the sinus, and thus increase the success rate of sinus angiography and the image quality of sinus imaging. At the same time, pressurized injection can be achieved, and the whole process of deeper, longer and thinner sinus (cavity) can be displayed, thereby improving the diagnosis and treatment judgment of patients;

[0025] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] A closed pressurizing ring comprises a closed ring 1, Velcro buckles 2 symmetrically arranged on both sides of the closed ring 1, and a fixing belt 3 for connecting the two sets of Velcro buckles 2; the closed ring 1 is provided with a through hole 101 adapted to a syringe, and the closed ring 1 is symmetrically provided with through grooves 104 adapted to the Velcro buckle 2 on both sides, one end of the Velcro buckle 2 passes through one side of the through groove 104 and is bonded to the other side of the Velcro buckle 2; the Velcro buckle 2 is fixedly connected to the fixing belt 3.

[0027] Through the cooperation between the closed ring 1, the Velcro buckle 2 and the fixing belt 3, the syringe can be tightly attached to the through hole 101 of the closed ring 1 to form a sealed space between the sinus opening and the film, increase the resistance of the contrast agent to overflow from the sinus opening, reduce the overflow of the contrast agent, and increase the success rate of the contrast agent entering the sinus, thereby increasing the success rate of sinus angiography and the image quality of sinus development, and at the same time, pressurized injection can be achieved, and the entire deeper, longer and thinner sinus (cavity) can be displayed, thereby improving the patient's diagnosis and treatment judgment; through the bonding of the Velcro buckle 2, the tightness of the fixing belt 3 and the closed ring 1 on the patient's limbs can be well adjusted, making the patient comfortable and close to the skin with good airtightness.

[0028] As a possible implementation of the present solution, preferably, a cotton layer 4 is fixedly connected to the inner surface of the fixing belt 3; the provision of the cotton layer 4 can increase the comfort level of the patient when wearing the closed compression ring.

[0029] As a possible implementation of the present scheme, preferably, an annular groove 102 is opened at the through hole 101 on the outer surface of the closed ring 1, and a circular ring 5 is clamped in the circular groove 102. The circular ring 5 is fixedly connected to the fixing ring 7 via a connecting ring 6, and the side wall of the fixing ring 7 is in close contact with the inner wall of the through hole 101 and is flush with the inner surface of the closed ring 1 on the side away from the connecting ring 6; through the cooperation of the circular ring 5, the connecting ring 6 and the fixing ring 7, it can be achieved that when the diameter of the syringe becomes smaller, the closed pressurizing ring can still remain in close contact with the syringe, thereby forming a sealed space between the sinus opening and the film.

[0030] As a possible implementation of the present scheme, preferably, the top and bottom of the annular groove 102 are symmetrically provided with a clamping groove 103, and the top and bottom of the circular ring 5 are fixedly connected with an elastic ring 8, and the diameter of the elastic ring 8 is larger than the annular groove 102 and is adapted to the clamping groove 103; by the arrangement of the elastic ring 8 and the circular ring 5, the stability of the fixing ring 7 when fixed to the closed ring 1 can be increased, and the fixing ring 7 can be prevented from shifting between the closed ring 1 during injection, thereby destroying the closed space between the sinus opening and the film.

[0031] As a possible implementation manner of the present scheme, preferably, one end of the Velcro fastener 2 is fixedly connected with a buckle 9, and the other end of the Velcro is provided with multiple groups of through grooves 201, and the buckle 9 is adapted to the through grooves 201; by the arrangement of the buckle 9 and the through grooves 201, the stability of the Velcro fastener 2 when being fixed is increased.

[0033] As a possible implementation of the present scheme, preferably, an elastic layer 105 is fixed to the inner wall of the through groove 104; by providing the elastic layer 105, one end of the Velcro fastener 2 can maintain close contact with the through groove 104 when it passes through the through groove 104 and is bonded to the other end, thereby avoiding a gap between the sinus opening and the film.

[0034] The working principle of this device is:

[0035] When in use, first move the fixing belt 3 to the position corresponding to the sinus tract, then pass the two groups of Velcro buckles 2 through the two groups of through grooves 104 respectively, pull the Velcro buckles 2 to the side away from each other so that the closed ring 1 fits on the patient's skin. At this time, the sinus tract leaks out from the through hole 101. After pulling it to the appropriate position, press the Velcro buckle 2 to the other end so that the two ends stick together and the buckle 9 is engaged with the through groove 201 to fix the closed pressure ring; when the size of the syringe is reduced, press the circular ring 5, the connecting ring 6 and the fixing ring 7 to one side of the closed ring 1 so that the elastic ring 8 is engaged with the card groove 103, and the installation is completed at this time.
