Description

Technical Field

[0001] The invention belongs to the field of vomitus collection, and in particular relates to a vomitus care device after general anesthesia surgery. Background Art

[0002] Postoperative nausea and vomiting (PONV) is a common complication after general anesthesia. Its pathogenesis is closely related to the anesthetic drugs, the patient's constitution, and the type of surgery. Studies have shown that approximately 20%-30% of patients undergoing general anesthesia will experience varying degrees of PONV symptoms. Among them, women, non-smokers, and those with a history of motion sickness or postoperative vomiting have a significantly increased risk, with the incidence rate reaching 3-5 times that of ordinary patients. Inhalational anesthetics (such as isoflurane and sevoflurane) directly induce the vomiting reflex by stimulating the medullary chemoreceptor trigger zone, while opioid analgesics (such as fentanyl) indirectly increase the risk of vomiting by delaying gastric emptying time. Postoperative patients are mostly in the supine position. When vomiting, they need to force their heads to one side to avoid aspiration. However, those who have not fully recovered their consciousness or are physically weak often find it difficult to cooperate, resulting in vomitus contaminating the pillow, bed sheets, and even flowing into the ear canal. This not only increases the workload of nursing and cleaning, but may also cause serious complications such as aspiration pneumonia and wound dehiscence, significantly prolonging the patient's hospital stay.

[0003] Existing methods of handling vomitus have multiple limitations. Traditional hand-held plastic bags require patients or caregivers to maintain a continuous posture. When the vomiting reflex is severe, it is easy for the contents to leak due to hand tremors or lack of cooperation, polluting the medical environment. Although the open collection bag fixed to the bedside frees your hands, the exposure of vomitus to the air will accelerate the volatilization of malodorous substances. The concentration of its main components, volatile organic compounds such as hydrogen sulfide and indole, can reach a peak within 1 hour, causing strong discomfort to patients in the same ward, and even inducing anxiety. What is more worthy of attention is that vomitus that is not cleaned up in time may become a source of cross-infection. Studies have shown that Helicobacter pylori can survive in vomitus for more than 4 hours, significantly increasing the risk of nosocomial infection. These defects not only affect the quality of patients' postoperative recovery, but also increase the intensity and complexity of clinical nursing work.

[0004] Based on this, the present invention proposes a post-operative vomiting care device for general anesthesia to solve the problems existing in the above-mentioned prior art. Summary of the Invention

[0042] The following is attached with the instruction manual Figures 1-9 The structure of the post-operative vomiting care device after general anesthesia is described.

[0043] like Figures 1 to 9As shown, a post-operative vomiting care device for general anesthesia is used to be installed on one side of an operating table to collect post-operative nausea and vomiting, including a mounting frame 1, a collecting bucket 2 is detachably mounted on the bottom of the mounting frame 1, and a collecting bag is clamped and fixed on the surface of the connection between the collecting bucket 2 and the mounting frame 1 to collect the patient's vomit, and the storage portion of the collecting bag is located in the inner cavity of the collecting bucket 2. A sealing assembly is also installed on the inner side of the upper end of the mounting frame 1. The sealing assembly is used to seal vomit to prevent vomit from spilling and odor from escaping. It specifically includes symmetrically arranged sealing covers 3, one end of the two sealing covers 3 is movably mounted on the inner wall of the mounting frame 1 through a hinge plate, and the other end is a free end, and a rubber extrusion 24 is provided at the free end of the two sealing covers 3, and the butt joint of the two sealing covers 3 is sealed by the rubber extrusion 24; and a sealing sliding cavity 7 is also opened on one side wall of the mounting frame 1, and an insertion rod 5 is movably inserted into the interior of the sealing sliding cavity 7, and a return spring 8 is fixedly provided at the bottom of the insertion rod 5, and the other end of the return spring 8 is fixedly installed at the bottom of the sealing sliding cavity 7, and a soft pad 6 is also installed on the top of the insertion rod 5, and the soft pad 6 is used in conjunction with the patient, and the side wall of the insertion rod 5 is slidably connected to the side wall of the free end of the sealing cover 3, and the free end of the sealing cover 3 is flipped around the hinge end as the center axis through the up and down movement of the insertion rod 5.

[0044] In the above description, contactless opening and closing control is achieved through the patient's head movement. When the patient needs to vomit, the patient first turns his head over and presses his head against the cushion 6, driving the bottom insertion rod to move downward, and the insertion rod 5 moves downward, driving the two slidingly connected sealing covers 3 to rotate downward. The downward rotation of the sealing cover 3 can open the upper port of the mounting frame 1 as a whole, so that the patient's vomit can be collected. When the patient's head is reset, it is reset by the reset spring 8, and the sealing cover 3 can be re-sealed and reset. Under the mutual extrusion of the two rubber extrusion parts 24, a closed space is formed. This design can effectively avoid the risk of contamination caused by manual operation of medical staff.

[0045] In a preferred embodiment, Figure 3 、 Figure 4 and Figure 7 As shown, a guide protrusion 9 is also installed on the inner side wall of the insertion rod 5, and the outer wall of the guide protrusion 9 slides in the strip-shaped notch 4 opened on the side wall of the mounting frame 1, and the strip-shaped notch 4 is communicated with the sealing sliding cavity 7. The strip-shaped notch 4 is in a vertical state, and the end of the guide protrusion 9 is slidably arranged inside the guide slot 10 opened on the side wall of the sealing cover 3 to form a linkage structure.

[0046] In the above description, when the patient turns his head over and presses his head against the cushion 6, driving the bottom insertion rod 5 to move downward, the insertion rod 5 moves downward, and synchronously drives the guide protrusion 9 to move vertically downward along the strip notch 4. The strip notch 4 is used to guide and limit the movement of the guide protrusion 9. At the same time, the other side of the guide protrusion 9 slides inside the guide groove 10, thereby driving the free end of the sealing cover 3 with the guide groove 10 to rotate downward, and during the rotation, the upper opening of the mounting frame 1 is opened, so that the collection bucket 2 can collect vomit.

[0047] In a preferred embodiment, Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, the sealing cover 3 is further provided with a guide column 21 on the side wall away from the guide groove 10. The guide column 21 is engaged in the guide groove 20 inside the mounting frame 1 and can slide in the guide groove 20 as the free end of the sealing cover 3 rotates, thereby ensuring the stability of the sealing cover 3 when in use.

[0048] In a preferred embodiment, Figure 3 and Figure 4 As shown, a mounting groove 11 is further provided at the bottom of the side wall of the mounting frame 1, and a positioning protrusion 12 is installed on the top of the collecting bucket 2. The mounting groove 11 is adapted to the size of the positioning protrusion 12, and the mounting groove 11 and the positioning protrusion 12 are movably plugged in. The operator needs to vertically align the mounting groove 11 and the positioning protrusion 12, plug the mounting frame 1 and the collecting bucket 2 into each other, complete the installation operation, and at the same time complete the fixation of the upper opening of the collecting bag.

[0049] Specifically, the mounting groove 11 is a trapezoidal groove with a large opening and a small interior, and the positioning protrusion 12 is a trapezoidal protrusion that matches the shape of the mounting groove 11. During installation, the inclined surface of the trapezoidal groove of the mounting groove 11 guides the installation process of the positioning protrusion 12 and seals it after installation, thereby ensuring the connection efficiency between the mounting frame 1 and the collecting bucket 2 and the sealing of the connection between the mounting frame 1 and the collecting bucket 2 after connection.

[0050] In a preferred embodiment, Figure 2 As shown, a clamping block 13 is also installed on one side of the outer wall of the mounting frame 1. The clamping block 13 is a U-shaped part, and a clamping groove 14 is provided inside the clamping block 13. The clamping groove 14 is adapted to the outer frame of the bed, and a locking bolt 15 is threadedly connected to the bottom of the clamping block 13.

[0051] In the above description, when in use, the clamping block 13 is placed on the patient's bed frame through the clamping groove 14 inside the clamping block 13, and the entire installation of the device is completed by tightening the bolt 15.

[0052] In a preferred embodiment, Figure 1 、 Figure 2 and Figure 8 As shown, mounting plates 16 are fixedly mounted on the outer sides of both sidewalls of the mounting frame 1. L-shaped brackets 17 are symmetrically mounted on the bottom of the mounting plates 16. A pair of clips 18 are movably mounted on the bottom of the L-shaped brackets 17, with a gap between the clips 18. A locking block 19 is provided on the sidewall of the collection hopper 2. The locking block 19 is located on the same side as the mounting plate 16. The locking block 19 is cylindrical and, after installation, is placed in the cavity enclosed by the mounting plate 16, the L-shaped bracket 17, and the clips 18 to constrain the position of the locking block 19. Therefore, during the process of plugging the mounting frame 1 and the collection hopper 2 together, the locking block 19 moves upward, thereby pushing the clips 18 to flip. After flipping, the clips 18 return to their original position, and the locking block 19 now moves downward, being locked by the clips 18, reducing the possibility of the collection hopper 2 falling.

[0053] Specifically, the locking block 19 is retractably mounted on the side wall of the collection hopper 2, and a retractable protective sleeve 22 is also mounted on the inner side wall of the collection hopper 2 via a connecting bolt. The retractable protective sleeve 22 is connected to the locking block 19 via a compression spring 23. When removing the collection hopper 2, the locking blocks 19 on both sides are manually pressed down to squeeze the compression springs 23, which facilitates quick removal and installation of the collection hopper 2 during use, thereby improving the installation and removal efficiency of the collection hopper 2.

[0054] The implementation principle of the postoperative vomiting care device for general anesthesia in this embodiment is as follows:

[0055] First, the operator needs to put the garbage bag on the collection bucket 2, and make the edge of the garbage bag not lower than the position of the positioning protrusion 12, then vertically align the installation groove 11 and the positioning protrusion 12, and plug the installation frame 1 and the collection bucket 2 into each other. During the plugging process, the locking block 19 moves upward, thereby pushing the card plate 18 to flip over. After the flipping, the card plate 18 returns to its initial position, and at this time the locking block 19 moves downward, that is, it is locked by the card plate 18, reducing the possibility of the collection bucket 2 falling, and realizing the detachable connection between the installation frame 1 and the collection bucket 2.

[0056] At the same time, the clamping block 13 is placed on the patient's bed frame through the clamping groove 14 inside, and the entire device is installed and fixed through the locking bolt 15, so that the cushion 6 can match the position of the patient's head.

[0057] When the patient needs to vomit, the patient first turns his head over and presses the head against the cushion 6, driving the bottom insertion rod 5 to move downward. The insertion rod 5 moves downward, pushing the bottom return spring 8 to compress, and the return spring 8 is used to facilitate the later return operation, and the movement of the insertion rod 5 drives the guide protrusion 9 to move vertically downward along the strip notch 4, and the other side of the guide protrusion 9 slides inside the guide slide 10, thereby driving the sealing cover 3 with the guide slide 10 to rotate downward, and during the rotation process, when the mounting frame 1 is opened as a whole, vomitus can pass through the collection bucket 2. When the vomiting is completed later, the patient's head is reset, and the sealing cover 3 and the cushion 6 are driven to reset again by the return spring 8 to seal the vomitus, effectively avoiding problems such as gas pollution and cross infection.

[0058] The above-described embodiments merely illustrate several embodiments of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of the present invention. Therefore, the scope of the present invention shall be determined by the appended claims.
