[0021] To make the objectives, technical solutions, and advantages of the present invention more clear, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other implementations obtained by ordinary technicians in this field without making any creative work are within the scope of protection of the present invention.
[0022] Example 1 See also Figure 1 - Figure 8 A sterile treatment towel for a central venous catheter includes: a towel body 1, which is divided into a core area 11, a first folding area 12, a second folding area 13 and a third folding area 14. The first folding area 12 is located above the core area 11, the second folding area 13 is located on the left of the core area 11, and the third folding area 14 is located on the right of the core area 11. The core area 11 is used to place a catheter connector and perform treatment operations. The first folding area 12, the second folding area 13 and the third folding area 14 are folded in sequence when wrapping the towel body 1.
[0023] Furthermore, the guide component 2 is used to prompt the steps of folding the towel body 1; the guide component 2 includes a first prompt strip 21, a second prompt strip 22 and a third prompt strip 23, the first prompt strip 21 is connected to the first folding area 12, the second prompt strip 22 is connected to the second folding area 13, and the third prompt strip 23 is connected to the third folding area 14. A first folding groove is provided between the first folding area 12 and the core area 11, a second folding groove is provided between the second folding area 13 and the core area 11, and a third folding groove is provided between the third folding area 14 and the core area 11. STEP1 is marked on the first prompt strip 21, indicating that the first step when folding is to fold the first folding area 12, and STEP2 is marked on the second prompt strip 22, indicating that the second step is to fold the second folding area 13 toward the core area. The third folding area 14 is folded toward the core area 11, and the third prompt bar 23 is marked with STEP 3, which means that the third step is to fold the third folding area 14 toward the core area 11 so that the third folding area 14 covers the second folding area 13. At this time, the catheter connector is wrapped in the towel body 1, so that the catheter connector and the wound are placed in a sterile environment. The first folding groove, the second folding groove and the third folding groove are all pre-pressed grooves, which can enable the towel body 1 to be accurately folded along a fixed trajectory, thereby improving the accuracy of folding the towel body 1. Through the guidance of the guide component 2 and the partition setting of the towel body 1, novice medical staff can complete the wrapping operation in a short time, shortening the operation time and improving work efficiency. The clear folding grooves and step prompts reduce human errors during the operation, so that the operation of folding the towel body 1 is successful at one time and folded accurately.
[0024] In addition, the observation component 5 is used to observe the core area 11 after the towel body 1 is folded, and is used for: a first circular hole 15 is opened on the core area 11, the first circular hole 15 is an operation port, the patient's wound and the catheter connector are located in the first circular hole 15, a second circular hole 16 is opened on the second folding area 13, and a third circular hole 17 is opened on the third folding area 14. The observation component 5 includes an observation window 51, and the observation window 51 is connected to the third circular hole 17. The first circular hole 15, the second circular hole 16 and the third circular hole 17 overlap after the towel body 1 is folded. A transparent sticker 52 is pasted on the observation window 51, and a plurality of spare stickers 53 are stacked and pasted on the third folding area 14 to complete the three-step folding operation. After the operation, the first circular hole 15, the second circular hole 16 and the third circular hole 17 overlap. At this time, the wound and the catheter connector can be directly observed from the observation window 51 on the third circular hole 17. When the catheter connector needs to be operated, the transparent sticker 52 can be torn off to operate without opening the wrapped towel body 1. When the towel body 1 is opened, the catheter connector is not separated from the sterile environment and exposed to the external environment, which increases the risk of contamination by microorganisms in the air. After the operation is completed, a spare sticker 53 can be torn off and pasted on the observation window 51. The spare sticker 53 is the same as the transparent sticker 52. Both are disposable tools. Multiple spare stickers 53 can be used for multiple operations.
[0025] In addition, the third folding area 14 is connected to the first Velcro 3, and the second folding area 13 is connected to the second Velcro 4. The second Velcro 4 and the first Velcro 3 are adhered after the towel body 1 is folded. After the second Velcro 4 and the first Velcro 3 are adhered, they have the effect of fixing the current wrapped state of the towel body 1, and no additional pasting operation is required, which further improves the convenience of operation.
[0026] It is worth noting that the fixing component 6 is used to fix the catheter joint; the fixing component 6 includes a flexible strip 61, the flexible strip 61 is connected to the core area 11, the flexible strip 61 is set to a U shape, the first circular hole 15 is located on the inner side of the flexible strip 61, the core area 11 is also connected to an adsorption capsule 62, the two ends of the adsorption capsule 62 are in contact with the flexible strip 61, the flexible strip 61 is connected to a pressing belt 63, the pressing belt 63 is connected to a third Velcro 64, the flexible strip 61 is connected to a fourth Velcro 65, the flexible strip 61 can wrap the catheter joint, which helps to fix the catheter joint and reduce the shaking amplitude of the catheter joint. Since it is filled with super absorbent resin, the adsorption capsule 62 is relatively soft in texture, and the catheter joint can be placed on the relatively soft adsorption capsule 62 to stabilize the position of the catheter joint. After the catheter joint is installed, the pressing belt 63 is pressed on the catheter joint to make the third Velcro 64 and the fourth Velcro 65 adhere to each other, so that the pressing belt 63 can press the catheter joint tightly, thereby fixing the catheter joint and preventing the catheter joint from shaking when the patient moves the body, thereby affecting the wound. When the wound exudes fluid, the exuded fluid enters the core area 11, and the adsorption capsule 62 can absorb the fluid to prevent the fluid from spreading and causing contamination.
[0027] It is worth noting that the prompt component 7 is used to prompt medical staff when the wound is exuding. The prompt component 7 includes a mounting frame 72, which is connected to the third folding area 14. The inner wall of the mounting frame 72 is connected to a flexible plate 73, a liquid sac 75 and a porous cloth 76. The flexible plate 73 overlaps with the adsorption sac 62 after the towel body 1 is folded. A plurality of needles 74 are connected to the side of the flexible plate 73 close to the liquid sac 75. The porous cloth 76 is located on the side of the liquid sac 75 away from the flexible plate 73. A protective cover 71 is installed on the third folding area 14. The protective cover 71 is located above the flexible plate 73 and can be removed. The adsorption sac 62 expands after absorbing the liquid, and the adsorption sac 62 bulges upward and squeezes the flexible plate 73. After the flexible plate 73 is squeezed, it drives multiple The needle 74 is close to the liquid capsule 75 so that the needle 74 punctures the liquid capsule 75. The liquid capsule 75 contains iodine tincture. After the liquid capsule 75 is punctured, the iodine tincture seeps out, and part of the iodine tincture dyes the porous cloth 76. The porous cloth 76 is set to white. After the iodine tincture seeps out, the porous cloth 76 is dyed the color of iodine tincture, so that medical staff can judge that the wound has exudate after seeing the porous cloth 76 being dyed, and thus take relevant treatment measures. The flexible plate 73 and the mounting frame 72 are sealed. The iodine tincture cannot leak into the core area 11 through the flexible plate 73. Before the towel body 1 is wrapped, the protective cover 71 protects the flexible plate 73 to avoid pressing the flexible plate 73 and puncturing the liquid capsule 75. When the operation of wrapping the towel body 1 begins, the medical staff manually tears off the protective cover 71.
[0028] It is worth mentioning that two elastic straps 8 are connected to the third folding area 14. The two elastic straps 8 are used to tie the towel body 1 to the human body. When the patient needs to get out of bed and move around, medical staff can use the two elastic straps 8 to tie the towel body 1 to the human body to prevent the towel body 1 from falling off when the patient moves, thereby causing the towel body 1 to pull the catheter connector and cause wound damage.
[0029] Example 2 A method for wrapping a central venous catheter with a sterile treatment drape, using the sterile treatment drape for a central venous catheter in Example 1, further comprising the following steps: Step 1: Prepare the operating environment and items, ensure the operating table is sterile, take out the central venous catheter sterile treatment towel, check that the towel body 1 is not damaged and the prompt component 7 is intact, and tear off the protective cover 71; Step 2: Place the catheter connector and the wound in the first circular hole 15 of the core area 11, so that the U-shaped flexible strip 61 fits around the catheter connector, press the adsorption bag 62 to fit it against the bottom of the connector, and then press the pressing tape 63 onto the connector to bond the third hook and loop fastener 64 and the fourth hook and loop fastener 65 together; Step 3: Follow the instructions of the first prompt strip 21 and fold the first folding area 12 toward the core area 11 along the first folding groove to cover the area above the joint; Step 4: Following the guidance of the second prompt strip 22 , fold the second folding area 13 toward the core area 11 along the second folding groove so that the second circular hole 16 is aligned and overlaps with the first circular hole 15 ; Step 5: Follow the third prompt strip 23 and fold the third folding area 14 toward the core area 11 along the third folding groove to cover the second folding area 13, so that the third circular hole 17 overlaps with the first two circular holes. At the same time, fit the first hook and loop fastener 3 and the second hook and loop fastener 4 together to complete the basic wrapping. Step 6: If the patient needs to move, wrap the two elastic bands 8 around the patient's limbs and secure them to ensure that the towel body 1 is stable; for subsequent observation or operation, tear off the transparent sticker 52 on the observation window 51 and proceed. After the operation, use the spare sticker 53 to close the observation window 51.
