Description
Technical Field
[0001] The utility model relates to the technical field of pulsating vacuum pressure steam sterilization of blood tourniquets, in particular to a special coiling and fixing device for blood tourniquets. Background Art
[0002] The blood tourniquet is made of a rubber sheet with good elasticity, off-white in color, about 15 cm wide, and the length can be cut according to needs, generally cut into about 1 m. Before use, it can be disinfected by gas fumigation or boiling. The blood tourniquet is wound around the patient's limb, and by tightening the blood tourniquet, appropriate pressure is applied to the blood vessels to control and stop bleeding, thus protecting the patient's life safety.
[0003] The blood tourniquet can be reused, but it needs to be sterilized by pulsating vacuum pressure steam before and after use. During sterilization, the blood tourniquet is usually folded and then placed in the sterilizer for sterilization. However, when the blood tourniquets are folded together, the adjacent surfaces are tightly attached and there is no gap, so steam is difficult to penetrate, resulting in poor sterilization effect.
[0004] To avoid the phenomenon that the adjacent surfaces are tightly attached when the blood tourniquet is folded, non-woven fabric or cotton cloth is usually selected for lining and isolation support, that is, non-woven fabric or cotton cloth is padded between the adjacent surfaces, thus solving the problem that the sterilization medium is not easy to penetrate. However, when using non-woven fabric as the lining, due to factors such as the excessive length of the blood tourniquet, too many folding layers, and insufficient drying time, water vapor or a feeling of dampness when touched by hand is likely to appear on the surface of the non-woven fabric on the adjacent surfaces, and the sterilization quality cannot be guaranteed.
[0005] When using cotton cloth as the lining for isolation support, although the phenomenon of water vapor or a feeling of dampness when touched by hand on the adjacent surfaces is avoided, cotton floc residues are likely to appear, which may cause secondary pollution and other harms to the patient's wound, and the cleaning after use of pure cotton knitting is troublesome and costly. In addition, whether non-woven fabric or cotton cloth is selected for lining and isolation support, linings with the same width and length as the blood tourniquet need to be cut, which causes a certain waste of resources in terms of manpower and items. Summary of the Invention
[0006] The utility model aims to solve the problems that when the conventional blood tourniquet is directly folded for sterilization, steam is difficult to penetrate, resulting in unable to guarantee the sterilization quality, and the means of using non-woven fabric or cotton cloth for lining isolation has limited sterilization effect and high consumable cost.

Detailed implementation manners
[0033] The following makes a detailed description of the specific implementation manners of the present utility model in conjunction with the drawings:
[0034] As Figures 1 to 9 shown, the special coiling and fixing device for the blood-driving belt includes a hollow fixing device body 1 with a hollow structure, an inner clamping assembly 2, an outer clamping groove 3, and a support assembly 4. The fixing device body 1 is a hollow box body structure with a cover 102 that can be opened and closed left and right. The blood-driving belt can be wound inside the fixing device body 1, and the fixing device body 1 can be opened through the cover 102 to realize the taking out and putting in of the blood-driving belt.
[0035] In this embodiment, the fixer body 1 includes a fixed bottom plate 101 and a cover 102 buckled above the fixed bottom plate 101. The fixed bottom plate 101 is a circular plate. After the fixed bottom plate 101 and the cover 102 are connected and combined, they form a hollow cylindrical structure, as Figure 1 shown. The cover 102 is composed of a left cover 5 and a right cover 6. The left cover 5 includes a semi-circular arc-shaped side plate 51 and a semi-circular top plate 52. The left cover 5 and the right cover 6 have the same structure. The left cover 5 and the right cover 6 are symmetrically arranged on both sides above the fixed bottom plate 101 and are rotatably connected to the fixed bottom plate 101, thereby realizing the left and right opening and closing of the fixer body 1.
[0036] When the left cover 5 and the right cover 6 are installed, a rotating shaft 7 is threadedly connected to the fixed bottom plate 101. The rotating shaft 7 is vertically arranged at the rear edge of the fixed bottom plate 101. A circular edge limiting plate 71 is provided at the upper end of the rotating shaft 7. The diameter of the edge limiting plate 71 is larger than the diameter of the rotating shaft 7, as Figure 2 shown.
[0037] At the same time, a left rotating sleeve 8 is provided below the rear side of the left cover 5, and a right rotating sleeve 9 is provided above the rear side of the right cover 6. The left rotating sleeve 8 and the right rotating sleeve 9 are sleeved on the rotating shaft 7 up and down and can rotate along the rotating shaft 7. Furthermore, the left cover 5 and the right cover 6 can be opened. After opening, the fixer body 1 is in an open state, and the fixed bottom plate 101 is exposed.
[0038] In order to realize the locking and unlocking of the opening and closing of the fixer body 1, opening and closing handles 10 are provided on the front sides of the left cover 5 and the right cover 6. The opening and closing handles 10 and the outer clamping groove 3 are arranged at intervals, as Figure 3 shown. The opening and closing handle 10 is bent into a "[[" shape. A hand-tightening bolt 11 is provided between the opening and closing handles 10 on the left cover 5 and the right cover 6 to connect them, that is, the two opening and closing handles 10 are connected by the hand-tightening bolt 11.
[0039] Specifically, the number of hand-tightening bolts 11 is two. One hand-tightening bolt 11 is threadedly connected above the opening and closing handle 10 on the left cover 5. After the fixer body 1 is closed, this hand-tightening bolt 11 can be threadedly connected to the opening and closing handle 10 on the right cover 6. Another hand-tightening bolt 11 is threadedly connected below the opening and closing handle 10 on the right cover 6. After the fixer body 1 is closed, this hand-tightening bolt 11 can be threadedly connected to the opening and closing handle 10 on the left cover 5. Above, under the connection action of the two hand-tightening bolts 11, the two opening and closing handles 10 can be reliably connected to ensure the closed state of the fixer body 1, as Figure 7 and Figure 8 shown.
[0040] The side wall of the fixator body 1 is hollowed out, that is, a number of through holes 12 are provided on the fixed bottom plate 101, the left cover 5 and the right cover 6. The through holes 12 can communicate the inside and outside of the fixator body 1, and the purpose is to facilitate the internal and external circulation of high-temperature steam.
[0041] An inner clamping assembly 2 is arranged at the center inside the fixator body 1. The function of the inner clamping assembly 2 is to fix one end of the blood drive belt. The inner clamping assembly 2 includes a central rod 21 and a clamping member 22, as Figure 4 and Figure 5 shown. Specifically, the central rod 21 is threadedly connected to the center of the fixed bottom plate 101. The central rod 21 is vertically arranged. A clamping member 22 for clamping one end of the drive belt is sleeved on the central rod 21. The clamping member 22 can rotate and move up and down along the central rod 21.
[0042] The number of the clamping members 22 is at least one. Here, the number of the clamping members 22 is two. The clamping members 22 are clips, and the clips can be long-tail clips. Two clamping members 22 are used to clamp and fix one end of the blood drive belt. To prevent the clamping member 22 from detaching from the central rod 21, a central limit plate 13 for restricting the clamping member 22 is arranged at the upper end of the central rod 21. The central limit plate 13 is circular and its diameter is larger than that of the central rod 21, which can prevent the clamping member 22 from moving upward out of the central rod 21.
[0043] To fix the other end of the drive belt, an outer clamping groove 3 for clamping the other end of the drive belt is provided on the side wall of the cover 102 of the fixator body 1. That is, the outer clamping grooves 3 are arranged on the joint surfaces of the left cover 5 and the right cover 6. The outer clamping grooves 3 are slender narrow slits, and the outer clamping grooves 3 are arranged on the circumferential surface of the fixator body 1. By the mutual cooperation of the closed left cover 5 and right cover 6, the other end of the blood drive belt can be clamped and fixed through the outer clamping groove 3.
[0044] A support assembly 4 is also arranged inside the fixator body 1. The support assembly 4 is used to isolate and support the blood drive belt to avoid the adhesion between adjacent surfaces of the blood drive belt. The support assembly 4 includes a plurality of mounting rings 41 arranged in a concentric circle and support rods 42 for isolating and supporting the blood drive belt.
[0045] The mounting rings 41 are arranged coaxially above the fixed bottom plate 101. The number of the mounting rings 41 is three, and the central rod 21 is arranged at the center of the circles of the mounting rings 41. A plurality of support rods 42 are circumferentially and uniformly arranged above each mounting ring 41. From the inside to the outside, the number of the support rods 42 on the mounting rings 41 increases, and the support rods 42 on the adjacent mounting rings 41 are arranged in a staggered manner, which can facilitate the smooth winding of the blood drive belt on the support rods 42.
[0046] When the support rod 42 is installed, the support rod 42 is arranged vertically, the cross-section of the support rod 42 is in the shape of a "work" character, the height of the support rod 42 is adapted to the width of the blood-letting band, and the support rod 42 is arranged radially towards the mounting ring 41. The purpose is to use the upper and lower ends of the support rod 42 to limit the blood-letting band and prevent the blood-letting band from detaching from the support rod 42, as Figure 6 shown. The support rod 42 is threadedly connected to the mounting ring 41. Specifically, a threaded rod 14 is provided at the lower end of the support rod 42, and the threaded rod 14 is threadedly connected to the mounting ring 41, thereby realizing the detachable installation of the support rod 42.
[0047] The principle of the present utility model is as follows: When the blood-letting band needs to be sterilized by pulsating vacuum pressure steam, the blood-letting band is coiled in the fixator body 1, and a chemical indicator card is placed into the fixator body 1, and then the fixator body 1 is placed into the sterilizer for sterilization. The sterilization indicators can be judged by observing the color change of the chemical indicator card. It avoids the phenomenon that the blood-letting bands are in contact with each other during the sterilization process, which is beneficial to the penetration of the sterilization medium and the discharge of steam. At the same time, it also avoids the occurrence of cotton dust residue in the inner lining cotton cloth and the wet package phenomenon in the inner lining non-woven fabric, and the sterilization effect is more guaranteed.
[0048] The coiling operation of the above-mentioned blood-letting band is as follows: First, unscrew the hand-tightening bolt 11 and no longer connect the two opening and closing handles 10. At this time, turn the left cover 5 and the right cover 6 out to the left and right respectively, and then the fixed bottom plate 101, the inner clamping assembly 2 and the support assembly 4 are exposed. Clamp one end of the blood-letting band with the clamping member 22, and then coil the blood-letting band around the support rods 42 on the mounting rings 41 with different diameters from the inside to the outside. Use the support rods 42 to separate the adjacent surfaces of the blood-letting band. At this time, the blood-letting band is arranged in a spiral shape, as Figure 9 shown by the dotted line in the figure, avoiding the phenomenon that the blood-letting bands are close to each other.
[0049] Then close the left cover 5 and the right cover 6. By the closing and clamping of the left cover 5 and the right cover 6, the other end of the blood-letting band is fixed in the outer clamping groove 3. Finally, screw in the hand-tightening bolt 11 to connect and fix the two opening and closing handles 10 to ensure the clamping state of the other end of the blood-letting band. At this time, the fixator body 1 is in the closed state, and the blood-letting band is coiled in the fixator body 1.
[0050] It should be noted that: Since the length of the blood-letting band can be cut according to needs, the blood-letting bands may have different lengths. On the basis of ensuring that the two ends of the blood-letting band are respectively clamped and fixed by the clamping member 22 and the outer clamping groove 3, the blood-letting band can be coiled around the support rods 42 on the mounting rings 41 with different diameters. If the length of the blood-letting band is longer, a larger number of support rods 42 can be used to separate the blood-letting band. If the length of the blood-letting band is shorter, a longer number of support rods 42 can be used to separate the adjacent surfaces of the blood-letting band.
[0051] The above-described embodiments are only the preferred embodiments of the present utility model, and do not limit the scope of implementation of the present utility model. Therefore, any equivalent changes or modifications made according to the structure, features, and principles described in the scope of the present utility model patent shall be included within the scope of the patent application of the present utility model.
