Description

Technical Field

[0001] The utility model relates to a drainage film for head surgery. Background Art

[0002] The wound needs to be flushed after neurosurgery. The current clinical practice is to stick a film around the wound to block water, and then use physiological sodium chloride solution or other flushing fluid to flush the wound. Flushing the wound can remove foreign matter, inflammatory secretions, necrotic tissue and other wound residues in the wound, so as to reduce the risk of wound infection and promote wound healing.

[0003] At present, the drainage film commonly used in wound irrigation operations is described in the patent document of Chinese Patent Publication No. CN205659094U, which can form a barrier around the wound and guide the wound residue and irrigation fluid generated by the wound irrigation to the drainage bag for collection;

[0004] However, during the actual wound irrigation process, some tissue specimens need to be collected and stored separately, so a drainage film is needed that can collect irrigation fluid and wound residues while collecting tissue specimens and separating them from the irrigation fluid.

The liquid collection layer can be used to collect flushing fluid and wound residues generated during wound flushing, and the specimen collection layer can be used to collect tissue specimens generated during wound flushing. The specimen collection layer and the liquid collection layer are separated into dry and wet states by the separation membrane.

[0011] By adopting the above technical solution, the film can be used to surround the surgical wound, and the wound residues produced by wound flushing will be mixed with the flushing liquid and flow into the liquid collection layer for collection. The specimen collection layer is far away from the film, and there is a liquid collection layer between it and the film. The specimen collection layer and the liquid collection layer are separated by a partition membrane. Tissue specimens can be placed in the specimen collection layer for collection and preservation, and due to the separation of the partition membrane, the specimen collection layer and the liquid collection layer are separated into dry and wet states, thereby achieving the purpose of independently preserving tissue specimens.

[0012] Furthermore, the pocket structure includes an adjustable support strip, which is laterally arranged at the pocket opening of the pocket structure and connected to one side of the separation membrane. The pocket structure can adjust the size of the pocket opening of the liquid collection layer by operating the adjustable support strip.

[0013] Furthermore, the adjustable support bar is an iron wire.

[0014] Furthermore, a funnel-shaped structure is connected to the bottom of the liquid collection layer, and a drainage tube is connected below the funnel-shaped structure.

[0015] Furthermore, a metering conduit is connected between the drainage tube and the funnel-shaped structure, and scale lines are formed on the surface of the metering conduit.

[0016] Furthermore, the drainage tube is connected to a one-way valve interface.

[0017] Furthermore, a filter screen is provided in the funnel-shaped structure, and the filter screen is located above the drainage tube.

[0018] Furthermore, a plurality of specimen collection bags are connected to the bottom of the specimen collection layer, and both upper and lower ends of the specimen collection bags are open, and sealing strips are provided at both upper and lower openings of the specimen collection bags.

[0019] Furthermore, tear lines are provided between the specimen collection bags.

[0020] Furthermore, water-blocking strips are provided on both sides of the film, and an air nozzle is provided on one side of the water-blocking strip, and the air nozzle is used to realize the inflation and deflation of the water-blocking strip.

[0021] The utility model has the following beneficial effects due to the adoption of the above technical solution:

[0022] 1. The utility model can not only realize enclosure around the wound, but also the wound residues generated by wound washing can be mixed with the washing liquid and flow into the liquid collection layer for collection. At the same time, the tissue specimens can be collected in the specimen collection layer, and the tissue specimens can be separated from the washing liquid, so as to achieve the purpose of independent preservation of the tissue specimens;

[0023] 2. The adjustable support strip in the utility model can adjust the size of the bag opening of the liquid collection layer, so that the size of the bag opening of the liquid collection layer can be flexibly adjusted according to the actual situation during wound irrigation;

[0024] 3. The liquid collection layer of the utility model includes a filter screen, which can filter wound residues mixed in the flushing liquid. In this way, after some tissue specimens are mixed in the flushing liquid and enter the liquid collection layer, they will also be blocked by the filter screen and will not be discharged along the drainage tube. Medical staff can easily move them from the liquid collection layer to the specimen collection layer, avoiding the problem of tissue specimens being mixed in the flushing liquid and discharged;

[0025] 4. In the utility model, the specimen collection layer is connected to a plurality of specimen collection bags, which are opened at the top and bottom and have sealing strips at the openings.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions.

[0040] Example 1

[0041] A drainage film for head surgery, comprising a film 1, wherein the film 1 is used to surround a wound during wound irrigation;

[0042] One side of the film 1 is formed with a back adhesive 11, such as Figure 1 , Figure 3 As shown;

[0043] The adhesive backing 11 is located on the side of the film 1 that is attached to the patient's skin, and the adhesive backing 11 is used to attach the film 1 to the patient's skin surface;

[0044] A water blocking strip 12 is connected to the surface of the film 1 on the side opposite to the adhesive 11. Figure 1 , Figure 2 As shown;

[0045] The water blocking strip 12 is vertically connected to the left and right sides of the side surface of the film 1. Figure 1 , Figure 2 As shown;

[0046] The water blocking strip 12 can block the flushing liquid on the surface of the film 1, thereby guiding the flow direction of the flushing liquid.

[0047] In this embodiment, the water blocking strip 12 is inflatable, and a gas nozzle is provided on one side of the water blocking strip 12, through which medical personnel can inflate and deflate the water blocking strip 12;

[0048] By designing the water blocking strip 12 to be inflatable, the storage volume of the drainage film can be reduced.

[0049] One side of the film 1 is connected to a pocket structure 2, such as Figure 1 , Figure 2 As shown;

[0050] During actual use, medical staff sticks the film 1 to the patient's skin surface through the adhesive backing 11 and exposes the wound. When the medical staff flushes the wound with flushing liquid, the flushing liquid mixed with wound residues will flow to the side of the pocket structure 2 under the guidance of the water-blocking strip 12, and then flow into the pocket structure 2.

[0051] The pocket structure 2 includes a liquid collection layer 21 and a specimen collection layer 22. Figure 1 , Figure 3 As shown;

[0052] The liquid collection layer 21 is close to one side of the film 1, such as Figure 1 As shown;

[0053] The liquid collection layer 21 is between the film 1 and the specimen collection layer 22. Figure 1 , Figure 3 As shown;

[0054] The flushing liquid flows to one side of the pocket structure 2 under the guidance of the water-blocking strip 12 , and further flows into the liquid collection layer 21 for collection.

[0055] A separation membrane 23 is provided between the liquid collection layer 21 and the specimen collection layer 22. Figure 3 As shown;

[0056] The separation membrane 23 separates the liquid collection layer 21 from the specimen collection layer 22, thereby achieving dry and wet separation between the two.

[0057] In this way, wound residues generated during the wound flushing process are mixed with the flushing liquid and flow into the liquid collection layer 21 for collection. At the same time, tissue specimens collected during the flushing process can be collected in the specimen collection layer 22, and the tissue specimens can be separated from the flushing liquid, thereby achieving the purpose of independent preservation of the tissue specimens.

[0058] The pocket structure 2 includes an adjustable support strip 24, which is laterally arranged at the pocket opening of the pocket structure 2. Figure 1 , Figure 3 As shown;

[0059] The adjustable support strip 24 is formed on one side of the separation membrane 23. Figure 3 As shown;

[0060] In this embodiment, the adjustable support bar 24 is a wire;

[0061] The adjustable support strip 24 is plastic, and the medical staff can control and bend the adjustable support strip 24 to adjust the size of the pocket opening of the liquid collection layer 21 in the pocket structure 2;

[0062] In this way, the size of the bag opening of the liquid collection layer 21 can be flexibly adjusted according to the actual situation during wound irrigation.

[0063] The bottom of the liquid collection layer 21 has a funnel-shaped structure 25, and the funnel-shaped structure 25 is integrally formed with the pocket structure 2;

[0064] The bottom of the funnel-shaped structure 25 is connected to a metering conduit 3, and one end of the metering conduit 3 is integrally formed with the bottom of the funnel-shaped structure 25. Figure 1 , Figure 4 As shown;

[0065] One end of the metering conduit 3 is connected to the funnel-shaped structure 25. Figure 4 As shown;

[0066] The end of the metering conduit 3 away from the funnel-shaped structure 25 is connected to a drainage tube 4. Figure 1 As shown;

[0067] In this embodiment, a control valve is provided between the metering conduit 3 and the drainage tube 4;

[0068] The metering conduit 3 is a transparent conduit, and a scale line 31 is provided on the surface of the metering conduit 3. Figure 4 As shown;

[0069] When the control valve is closed, the flushing liquid flows into the metering catheter 3 and medical staff can record the inflow of the flushing liquid according to the scale line 31; after the control valve is opened, the flushing liquid will flow out along the drainage tube 4.

[0070] One end of the drainage tube 4 is connected to a one-way valve interface 41, and the one-way valve interface 41 is used to connect to the drainage bag;

[0071] The flushing fluid can flow into the drainage bag along the drainage tube 4 for collection;

[0072] The drainage tube 4 is connected to the drainage bag via a one-way valve interface 41 , which can prevent the flushing fluid from flowing back into the drainage tube 4 .

[0073] A filter screen 5 is provided in the liquid collection layer 21;

[0074] Furthermore, the filter screen 5 is fixedly connected to the funnel-shaped structure 25, such as Figure 3 As shown;

[0075] The filter net 5 can filter the wound residues mixed in the flushing liquid, so that after some tissue specimens are mixed in the flushing liquid and enter the liquid collection layer 21, they can be blocked by the filter net 5 and will not enter the drainage tube 4; when medical personnel need to collect the tissue specimen, they can move it from the liquid collection layer 21 to the specimen collection layer 22, avoiding the problem of tissue specimens being mixed in the flushing liquid and discharged.

[0076] It should be noted that the drainage film is a disposable medical product, and the product volume needs to be as small as possible for easy storage, so the pocket structure 2 and the filter 5 are preferably made of polypropylene or polyester materials;

[0077] A certain deformation margin is left on the upper section of the separation membrane 23 to ensure that when the size of the bag opening of the liquid collection layer 21 is adjusted, the filter screen 5 will not be pulled and deformed.

[0078] A plurality of specimen collection bags 6 are connected to the bottom of the specimen collection layer 22, and both upper and lower ends of the specimen collection bags 6 are open;

[0079] The openings of the specimen collection bags 6 are connected in sequence from top to bottom. Figure 5 As shown;

[0080] The opening of the specimen collection bag 6 at the top is connected to the bottom of the specimen collection layer 22, and a tear line 62 is provided at the connection between the specimen collection bag 6 and the bottom of the specimen collection layer 22;

[0081] The connection between the specimen collection bags 6 is provided with a tear line 62, such as Figure 5 As shown;

[0082] The opening of the specimen collection bag 6 is provided with a sealing strip 61. Figure 5 As shown;

[0083] When actually used in surgery, the bottom side of the specimen collection bag 6 at the bottom is sealed by a sealing strip 61. After the tissue specimen is placed in the specimen collection layer 22, since the specimen collection bags 6 are connected by openings, the tissue specimen will fall into the specimen collection bag 6 at the bottom. The medical staff operates the sealing strip 61 on the upper side of the specimen collection bag 6 to seal the specimen collection bag 6, and then the specimen collection bag 6 can be easily separated from the main body through the tear line 62, thereby completing the collection of an assembled specimen.

[0084] In this embodiment, the number of specimen collection bags 6 is three.

[0085] Example 2

[0086] This embodiment is different from the embodiment 1 in that a fixing member 7 is provided in the pocket structure 2, such as Figure 6 As shown;

[0087] The top of the fixing member 7 is open, and one side thereof is fixedly connected to the inner wall of the liquid collection layer 21. A groove matching the shape of the high-frequency electric knife and the bipolar is formed in the fixing member 7;

[0088] The fixture 7 can be used to place a high-frequency electrosurgical unit and a bipolar unit.

[0089] In this embodiment, the number of specimen collection bags 6 is four.

[0090] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to achieve basically the same technical effects are all included in the protection scope of the present invention.
