[0026] Example:
[0027] As attached Figure 1 To be continued Figure 5 As shown:
[0028] This utility model provides a negative pressure drainage device, including a drainage component 1; the drainage component 1 includes a collection bottle 11 and a plug 12, the top end of the collection bottle 11 is fixedly connected to a drainage tube 1101, the top end of the drainage tube 1101 is inserted into the user's abdomen, the plug 12 is threaded to the bottom of the collection bottle 11, and a bracket 3 is sleeved on the outside of the collection bottle 11; a negative pressure bottle 2 is snapped into the right side of the inner side of the bracket 3; a negative pressure adjusting component 4 is fixedly connected inside the negative pressure bottle 2; the negative pressure adjusting component 4 includes a fixing tube 41 and a piston rod 42, the inside of the fixing tube 41 communicates with the inner cavity of the negative pressure bottle 2, the piston rod 42 is snapped into the inside of the fixing tube 41, and a connecting plate 4202 is fixedly connected to the top end of the piston rod 42; an adjusting rod 5 is snapped into the inside of the connecting plate 4202.
[0029] As attached Figure 2 As shown, a knob plate 501 is fixedly connected to the top of the adjusting rod 5. Two baffles 502 are fixedly connected to the outside of the adjusting rod 5 and below the knob plate 501. The two baffles 502 are located on the upper and lower sides of the connecting plate 4202, respectively. After rotating the knob plate 501, the adjusting rod 5 is driven to engage with the internal threaded tube 4101, so that the adjusting rod 5 rotates upward and moves. The connecting plate 4202 is driven to move synchronously through the two baffles 502, so as to realize the vertical height adjustment of the piston rod 42.
[0030] As attached Figure 1and attached Figure 2 As shown, a connecting tube 201 is fixedly connected to the top of the negative pressure bottle 2. The other end of the connecting tube 201 is fixedly connected to the inside of the effusion bottle 11. The connecting tube 201 connects the inner cavity of the negative pressure bottle 2 with the inner cavity of the effusion bottle 11. After the negative pressure inside the negative pressure bottle 2 is adjusted, a negative pressure is formed inside the effusion bottle 11 through the connecting tube 201, thereby better draining the effusion such as bile in the abdomen of hepatobiliary patients that needs to be drained, thus achieving the drainage effect.
[0031] As attached Figure 2 As shown, the left side of the bracket 3 is an inverted conical ring with a wider top and a narrower bottom, and the fluid collection bottle 11 is snapped into the ring. The right side of the bracket 3 is a cylindrical ring, and a hook 301 is attached to the back of the bracket 3. The hook 301 can be hung on the waist of the patient's gown or the pocket of the upper garment. The bracket 3 can be used to carry the drainage device 1 and the negative pressure bottle 2 at the same time, which is convenient for daily activities such as going to the toilet and walking. Compared with the traditional three-bottle negative pressure drainage device, the structure is simpler, lighter, and easier to carry.
[0032] As attached Figure 3 Appendix Figure 4 and attached Figure 5 As shown, the top of the fixed tube 41 is a sealed structure, but the middle is penetrated by the piston rod 42. The top surface of the fixed tube 41 is fixed and vertically provided with an internally threaded tube 4101. The internally threaded tube 4101 is threadedly connected to the adjusting rod 5. The bottom of the piston rod 42 is fixedly bonded with a piston plate 4201. The outer wall of the piston plate 4201 is tightly attached to the inner wall of the fixed tube 41. When the connecting plate 4202 is driven to move upward, the piston rod 42 pulls the piston plate 4201 upward, which extracts the gas inside the negative pressure bottle 2, thereby increasing the pressure difference of the negative pressure to balance the pressure change after the liquid is drained.
[0033] As attached Figure 1 and attached Figure 3 As shown, a sealing plug 1201 is fixedly connected to the inner top of the plug 12. The sealing plug 1201 is inserted into the bottom of the drainage bottle 11. The drainage bottle 11 has an inverted conical structure and may have scale lines on its outer surface. In the later stages of drainage, as the user gradually adapts to the body's state, the amount of drainage decreases. The inverted conical structure can better determine the amount of drainage for recording and to help determine whether to consider removing the tube. The sealing plug 1201 can keep the bottom of the drainage bottle 11 flush, making the reading more accurate.
[0034] The specific usage and function of this embodiment are as follows:
[0035] In this utility model, after rotating the knob plate 501, the adjusting rod 5 engages with the internal threaded tube 4101, causing the adjusting rod 5 to rotate upward and move. The two baffles 502 drive the connecting plate 4202 to move upward synchronously. The piston rod 42 pulls the piston plate 4201 upward, drawing out the gas inside the negative pressure bottle 2, thereby increasing the pressure difference of the negative pressure to balance the pressure change after the liquid is drained or after the liquid is discharged.
[0036] In the later stages of drainage, as the user gradually adapts to their body's condition, the fluid accumulation decreases. The inverted cone-shaped structure can better determine the amount of fluid accumulation for recording purposes, which helps in deciding whether to consider removing the tube.
