Description

Technical Field

[0001] This utility model relates to the field of drainage device technology, specifically to a drainage device for clinical use in critical care medicine. Background Technology

[0002] Critical care medicine is the discipline that monitors and treats critically ill patients who require immediate resuscitation, patients after complex major surgeries, and patients whose lives are in danger and whose vital signs need constant monitoring. However, patients with cardiothoracic diseases, such as pneumothorax, traumatic moderate hemothorax, persistent pleural effusion, and empyema, usually require clinical treatment and drainage devices to drain the pleural effusion.

[0003] Closed chest drainage involves inserting one end of a drainage tube into the pleural cavity, while the other end is connected to a water-seal bottle positioned lower down. This allows for the drainage of air or collection of fluid from the pleural cavity, enabling the lung tissue to reopen and restore function. As a treatment method, it is widely used for the drainage of hemothorax, pneumothorax, and empyema, as well as post-thoracotomy procedures, playing a vital role in the treatment of these diseases.

[0004] However, in the actual application of traditional drainage devices for draining pleural effusions, such as fluid, air, blood, and pus, they need to be placed in a lower position within the patient's chest cavity to facilitate the drainage of fluid and air. This results in extremely slow and low drainage efficiency for fluid and air, and it is also inconvenient to protect the water-seal bottle or hang it on the bed. Utility Model Content

Detailed Implementation

[0022] The present invention will now be described in detail with reference to the accompanying drawings.

[0023] As attached Figure 1 To be continued Figure 4 ,

[0024] Example 1:

[0025] This embodiment proposes a drainage device for clinical use in critical care medicine, including a storage bottle 1. The storage bottle 1 is provided with a protective mechanism 2. The protective mechanism 2 includes a bottom frame 201 and a top frame 202 that are slidably disposed on the outer surface of the storage bottle 1, and a connecting strip 203 that is fixed to the upper surface of the bottom frame 201 and engages with a protrusion on the outer surface of the top frame 202. The protective mechanism 2 also includes a hanging component connected to the top frame 202, which is used to hang the storage bottle 1 on the hospital bed.

[0026] refer to Figures 1 to 4 The protective mechanism 2 can be easily installed on the outside of the storage bottle 1, which not only protects the storage bottle 1, but also allows the storage bottle 1 to be hung on the hospital bed through the hanging component, thereby improving the practicality of the overall device. After the fluid is drained, the protective mechanism 2 and other components can be removed for subsequent reuse.

[0027] The bottom frame 201 is fitted onto the lower part of the storage bottle 1, and the top frame 202 is fitted onto the upper part of the storage bottle 1. By setting the bottom frame 201 and the top frame 202, the bottom frame 201 and the top frame 202 can be stably connected to the upper and lower ends of the storage bottle 1 by the snap-fit ​​method of the connecting strip 203, thereby protecting the storage bottle 1 and preventing the corners of the storage bottle 1 from being broken by the impact of sharp objects.

[0028] As a supplement, the bottom frame 201 and the top frame 202 can be detached from the storage bottle 1, which facilitates the installation and protection of different storage bottles 1. At the same time, after the storage bottle 1 is used, the bottom frame 201 and the top frame 202 can be removed and reused.

[0029] Example 2:

[0030] The hanging assembly includes two sets of fixing blocks 204 fixed to the upper surface of the top frame 202, and a rotating rod 205 rotatably connected to the fixing blocks 204. Hooks 206 are fixedly connected to both ends of the rotating rod 205.

[0031] By setting up a hanging component, the storage bottle 1 can be easily hung on the hospital bed, thus facilitating the placement of the storage bottle 1 and enabling medical staff to operate the drainage component to extract and drain effusions and air from the patient's pleural cavity.

[0032] As a supplement, when the storage bottle 1 is hung on the hospital bed, the hook 206 can be manually rotated from the fixed block 204 so that the hook 206 can be displayed from the top frame 202, and then hung on the hospital bed. Two sets of hanging components are provided to facilitate hanging operations on both sides, improving practicality.

[0033] Example 3:

[0034] The storage bottle 1 has a pre-drilled hole on its upper surface that is fixedly connected to a connecting cylinder 3 and a sealing component connected to the connecting cylinder 3. The storage bottle 1 also has a drainage component connected to the sealing component on its exterior.

[0035] refer to Figures 1 to 4 The drainage component is designed to allow for negative pressure operation by manually squeezing the components inside, which facilitates the extraction and drainage of pleural effusions and air from the patient's chest cavity, thereby significantly improving drainage efficiency.

[0036] Example 4:

[0037] The sealing assembly includes a sealing cap 4 that is threaded into the inner wall of the connecting cylinder 3, and a fixing tube 5 that penetrates the sealing cap 4 and extends into the storage bottle 1. The sealing assembly also includes a one-way vent valve 6 installed in a pre-drilled hole on the upper surface of the sealing cap 4.

[0038] By setting a sealing component, the storage bottle 1 can be easily sealed to prevent liquid from leaking out of the storage bottle 1. Furthermore, the detachable design of the sealing cap 4 makes it easy to disassemble and assemble the storage bottle 1 and the sealing component.

[0039] As a supplement, the one-way vent valve 6 is designed to stabilize the air pressure inside the storage bottle 1 when liquid enters it, thus preventing expansion when liquid enters the storage bottle 1.

[0040] Example 5:

[0041] The drainage assembly includes a connecting tube 7 connected to the upper end of the sealing cap 4, and a negative pressure hose 8 connected to the outer end of the connecting tube 7. A thoracic connecting tube 11 is installed at the input end of the negative pressure hose 8.

[0042] By setting up a drainage component, it is easy to extract pleural effusion from the patient's chest cavity. Through the cooperation of the negative pressure tubing 8 and subsequent components, the pleural effusion from the patient's chest cavity can be extracted and transferred.

[0043] As a supplement, when draining pleural effusion from a patient, the negative pressure hose 8 is manually pressed to deform it, and the pressure inside the negative pressure hose 8 changes through the cooperation of subsequent components, thereby enabling the drainage of pleural effusion from the patient.

[0044] The drainage assembly also includes a one-way input valve 10 and a one-way output valve 9 installed at the input and output ends of the negative pressure hose 8, respectively. The one-way input valve 10 is used to drain and extract effusion from the patient's pleural cavity through the thoracic connection tube 11; the one-way output valve 9 is used to discharge the liquid in the negative pressure hose 8 in one direction.

[0045] By setting up a drainage assembly, including a one-way output valve 9 and a one-way input valve 10, the gas inside the negative pressure hose 8 can be discharged in advance through the one-way output valve 9 when the negative pressure hose 8 is pressed. This allows the fluid to be drawn out when the negative pressure hose 8 rebounds, through the cooperation of the one-way input valve 10 and the thoracic connection tube 11.

[0046] As a supplement, after the gas in the negative pressure hose 8 is discharged into the storage bottle 1 through the connecting pipe 7, the excess gas in the storage bottle 1 can be discharged through the sealing component, thereby facilitating the storage of accumulated liquid.

[0047] The negative pressure hose 8 is made of medical silicone, and the outer surface of the storage bottle 1 is marked with graduation lines.

[0048] By setting scale lines, medical staff can easily observe the amount of liquid stored in the storage bottle 1. The storage bottle 1 is made of transparent material, which further facilitates the observation of the liquid stored in the storage bottle 1. The negative pressure hose 8 is made of medical silicone, which can easily return to its original position when pressed.

[0049] How to use:

[0050] In clinical use, firstly, by rotating the lever 205 and the hook 206, the storage bottle 1 is hung on the bed by the hook 206. Then, the drainage component is connected to the sealing component. The pleural connecting tube 11 in the drainage component is connected to the drainage tube in the patient's body to facilitate the drainage of pleural effusion.

[0051] At this time, by pressing the negative pressure hose 8, the negative pressure hose 8 deforms, causing the gas in the negative pressure hose 8 to be discharged through the one-way output valve 9. The one-way output valve 9 then transmits the gas to the storage bottle 1 through the connecting tube 7. The gas is then discharged to the outside by the one-way exhaust valve 6 in the sealing assembly. When the pressure on the negative pressure hose 8 is released, the negative pressure hose 8 can rebound and reset, allowing the negative pressure hose 8 to draw and drain the effusion in the patient's body through the one-way input valve 10 and the chest cavity connecting tube 11. The effusion is stored in the negative pressure hose 8 in sequence through the chest cavity connecting tube 11 and the one-way input valve 10. Pressing the negative pressure hose 8 again can transmit the effusion in the negative pressure hose 8 to the storage bottle 1 for storage through the one-way output valve 9.

[0052] Although the present invention has been disclosed above with reference to preferred embodiments, these are not intended to limit the present invention. Anyone skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention should be defined by the scope of protection of the claims of this application.
