Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a drainage fluid specimen collection bottle with negative pressure. Background Art

[0002] Currently, drainage fluid specimen collection bottles are used to collect secretions, which are produced by the body organs of patients with common diseases or infectious diseases. After the secretions are collected, they are tested or subjected to other operations. Generally speaking, the secretions are first collected from the patient's body through a drainage bag, and then transferred to the drainage fluid specimen collection bottle.

[0003] Commonly used drainage fluid specimen collection bottles are ordinary open-top plastic bottles with screw-caps. To collect drainage fluid for testing, the cap must be unscrewed, the drainage fluid from the desired drainage bag poured into the bottle, and the cap must be re-closed. However, there are several issues: drainage fluid testing must be performed under aseptic conditions, and unscrewing the cap exposes the fluid to air for extended periods, making it impossible to guarantee the sterility of the collected drainage fluid. Furthermore, some patients suffer from infectious diseases, and their secretions are contagious. This process of pouring the drainage fluid can easily lead to infection among medical staff and other personnel involved.

[0004] Therefore, the existing technology still needs to be improved and developed. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this application is to provide a drainage fluid specimen collection bottle with negative pressure, aiming to ensure that the drainage fluid specimen collection bottle is stably connected to the drainage bag, and prevent the drainage fluid specimen collection bottle from being disconnected from the drainage bag when the drainage fluid in the drainage bag is removed, thereby affecting the collection of drainage fluid and causing personal infection.

[0006] The technical solution adopted by this application to solve the technical problem is as follows: a drainage fluid specimen collection bottle with negative pressure, comprising:

[0007] a negative pressure chamber, the negative pressure chamber being used to collect drainage fluid;

[0008] a bottle cap, the bottle cap being mounted on the negative pressure chamber;

[0009] A connector is inserted into the bottle cap, and the connector includes a snap ring, into which the drainage bag extends.

[0010] Furthermore, the connector includes a transmission tube, one end of the transmission tube is inserted into the bottle cap, and the locking ring is sleeved on the other end of the transmission tube.

[0011] Furthermore, the connector further includes a one-way valve, which is disposed in the transmission tube. The transmission tube allows the liquid to flow in one direction toward the negative pressure chamber through the one-way valve.

[0012] Furthermore, the drainage bag includes a bag body and a connector, wherein the connector is provided on the bag body and connected to the connector.

[0013] Furthermore, the connecting piece includes a valve switch and a connecting pipe, and the valve switch is arranged on the connecting pipe.

[0014] Furthermore, the connecting pipe penetrates the engaging ring and the transmission pipe, and the connecting pipe and the transmission pipe are interference fit.

[0015] Furthermore, the transmission pipe penetrates into the connecting pipe, and the transmission pipe and the connecting pipe are interference fit.

[0016] Furthermore, the connector also includes a bottle stopper, which is detachably mounted in the locking ring.

[0017] Furthermore, the connector also includes a tie, one end of the tie is fixed on the bottle cap, and the other end of the tie is fixed on the bottle stopper.

[0018] Furthermore, scale lines are provided on the negative pressure chamber.

[0019] Beneficial effects:

[0020] The present application provides a drainage fluid specimen collection bottle with negative pressure, which is used to collect drainage fluid in a drainage bag. The drainage fluid specimen collection bottle with negative pressure is connected to the drainage bag through a connecting head, and then a negative pressure environment is created in the negative pressure chamber. The negative pressure chamber draws the drainage fluid in the drainage bag through the negative pressure, so that the drainage fluid flows into the negative pressure chamber through the connecting head, avoiding the risk of contamination caused by spillage of the drainage fluid and the possible infection of surrounding relevant personnel, thereby protecting medical staff, patients and surrounding people to the greatest extent. At the same time, when there is less liquid in the drainage bag and it is impossible to effectively pour out and collect enough drainage fluid for inspection, the negative pressure chamber can also attract the liquid in the drainage bag that is not easy to pour out into the negative pressure chamber, ensuring that the collection amount of drainage fluid meets the requirements. The bottle cap ensures the sealed environment of the drainage fluid specimen collection bottle with negative pressure, ensuring that the drainage fluid can be drawn into the negative pressure chamber, preventing the drainage fluid in the negative pressure chamber from splashing out, and preventing the external environment from contaminating the drainage fluid.

[0029] The present invention provides a drainage fluid specimen collection bottle with negative pressure. To make the purpose, technical solution, and effects of the present invention more clear and explicit, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely for the purpose of explaining the present invention and are not intended to limit the present invention.

[0030] like Figures 1 to 3 As shown, a drainage fluid specimen collection bottle with negative pressure is used to ensure that the drainage fluid specimen collection bottle is stably connected to the drainage bag 4, to prevent the drainage fluid specimen collection bottle from being disconnected from the drainage bag 4 when collecting the drainage fluid in the drainage bag 4, thereby affecting the collection of the drainage fluid and causing personal infection, thereby ensuring the safety of the drainage fluid collection. The drainage fluid specimen collection bottle with negative pressure includes a negative pressure chamber 1, a bottle cap 2 and a connecting head 3. The negative pressure chamber 1 is a collection bottle with negative pressure, and the liquid in the drainage bag 4 is collected through the negative pressure chamber 1; the bottle cap 2 is installed on the negative pressure chamber 1 to ensure that the negative pressure chamber 1 is sealed, maintain the negative pressure environment in the negative pressure chamber 1, and prevent other foreign objects from falling into the negative pressure chamber 1. At the same time, it also prevents the drainage fluid collected in the negative pressure chamber 1 from splashing out and causing adverse effects on the surrounding environment and personnel; the connecting head 3 is passed through the bottle cap 2, and the drainage bag 4 is connected to the negative pressure chamber 1 through the connecting head 3, so that the drainage fluid in the drainage bag 4 flows into the negative pressure chamber 1. Specifically, the connecting head 3 includes a snap ring 31, and the conveying structure of the drainage bag 4 extends into the snap ring 31. The connection between the drainage bag 4 and the negative pressure chamber 1 is fixed by the snap ring 31 to prevent the connection between the drainage bag 4 and the negative pressure chamber 1 from being disconnected and causing adverse effects on the collection of the drainage fluid. The snap ring 31 is made of elastic material. In this embodiment, the snap ring 31 is made of silicone material, so that the snap ring 31 has a certain elasticity. At the same time, the drainage bag 4 includes a bag body 41 and a connecting piece 42. The bag body 41 is used to collect secretions produced by the patient. The secretions flow directly from the patient's body into the bag body 41. The connecting piece 42 is set on the bag body 41 and is connected to the connecting head 3 through the connecting piece 42, so that the bag body 41 of the drainage bag 4 is connected to the negative pressure chamber 1 of the drainage fluid specimen collection bottle with negative pressure. At this time, the snap ring 31 is then connected to the connecting head 3 through the elastic fastening connecting piece 42, so that the negative pressure chamber 1 can suck the drainage fluid in the drainage bag 4 into the negative pressure chamber 1 through negative pressure to complete the collection of the drainage fluid.

[0031] In order to allow the drainage fluid in the drainage bag 4 to flow smoothly into the negative pressure chamber 1, the connector 3 includes a transmission tube 32. The outer shell of the transmission tube 32 is made of a hard material to prevent the transmission tube 32 from being deformed when it is reused. The inner wall of the transmission tube 32 is made of a soft material with a certain degree of ductility. When the connector 42 is inserted into the transmission tube 32, it can completely wrap the connector 42. Figure 1 and Figure 2As shown, one end of the transmission pipe 32 is arranged in the bottle cap 2, and then the transmission pipe 32 is communicated with the negative pressure cavity 1. The clamping ring 31 is arranged on the other end of the transmission pipe 32. At this time, the connecting member 42 is inserted into the clamping ring 31 and communicated with the transmission pipe 32. The clamping ring 31 is used to fix the connecting member 42 and the transmission pipe 32, so as to prevent the connecting member 42 and the transmission pipe 32 from being disconnected when the drainage liquid flows in the connecting member 42 and the transmission pipe 32, and avoid the drainage liquid from leaking to the outside environment, which affects the collection of the drainage liquid by the negative pressure cavity 1 and causes the infection.

[0032] When the drainage liquid flows into the negative pressure cavity 1, in order to avoid the drainage liquid from flowing back into the drainage bag 4 and affecting the transmission of the drainage liquid, the connecting head 3 further comprises a one-way valve 33. The one-way valve 33 is used to limit the flow direction of the drainage liquid, so as to ensure that the drainage liquid can only flow from the bag body 41 to the negative pressure cavity 1. Specifically, the one-way valve 33 is arranged in the transmission pipe 32. In this embodiment, the one-way valve 33 is in the shape of an eight character and is composed of two elastic flaps. One end of the elastic flap is fixed on the inner wall of the transmission pipe 32, and the other end of the elastic flap extends to one end of the negative pressure cavity 1. The tip of one of the elastic flaps abuts against the other elastic flap, so that the one-way valve 33 is arranged towards the bottom of the negative pressure cavity 1, as shown. Figure 1 When the connecting pipe 422 is communicated with the transmission pipe 32, the connecting pipe 422 can pass through the one-way valve 33 and output the drainage liquid into the negative pressure cavity 1. When the transmission of the drainage liquid is completed and the connecting pipe 422 is pulled out of the transmission pipe 32, the two elastic flaps of the one-way valve 33 are attached together, so as to prevent the drainage liquid in the negative pressure cavity 1 from flowing out of the negative pressure cavity 1 through the transmission pipe, and avoid the leakage of the drainage liquid in the negative pressure cavity 1.

[0033] Further, the connecting member 42 comprises a valve switch 421 and a connecting pipe 422. The valve switch 421 is arranged on the connecting pipe 422 and is used to control whether the drainage liquid can flow out of the drainage bag 4. Specifically, in this embodiment, the valve switch 421 passes through the connecting pipe 422. In order to control whether the drainage liquid can flow out of the drainage bag 4 by controlling the communication and blockage of the connecting pipe 422, the connecting pipe 422 is provided with a push-pull rod. The push-pull rod is slidingly arranged in the valve switch 421. When the push-pull rod slides to contact the closed end of the valve switch 421, the connecting pipe 422 is blocked. At this time, the drainage liquid cannot flow to the negative pressure cavity 1 through the connecting pipe 422. At the same time, it can also ensure that when the drainage bag 4 receives the secretion of the human body or needs to be moved after collecting the secretion, the secretion cannot flow out of the connecting pipe 422, so as to ensure the sealing property of the drainage bag 4 and prevent the leakage of the drainage liquid. Only when it is necessary to transport the drainage liquid to the negative pressure cavity 1, the push-pull rod is slid to move away from the closed end of the valve switch 421. The blockage of the connecting pipe 422 is removed, so that the drainage liquid in the bag body 41 flows into the negative pressure cavity 1 through the connecting pipe 422.

[0034] Further, in order to stably connect the connecting tube 422 and the transmission tube 32, prevent the connection of the connecting tube 422 and the transmission tube 32 from being disconnected when the drainage liquid in the drainage bag 4 flows to the negative pressure cavity 1, and affect the transportation of the drainage liquid, the connecting tube 422 penetrates into the snap ring 31 and the transmission tube 32, and the connecting tube 422 is in interference fit with the transmission tube 32. In order to reinforce the connection of the connecting tube 422 and the transmission tube 32, the transmission tube 32 is made of elastic material and has certain ductility at this time, so that when the connecting tube 422 penetrates into the transmission tube 32, the transmission tube 32 can wrap the connecting tube 422 to prevent the connecting tube 422 from falling off, and the snap ring 31 with elasticity is also fastened on the transmission tube 32, further preventing the connecting tube 422 from falling off from the transmission tube 32. When the transportation of the drainage liquid is completed, a certain force is applied to separate the connecting tube 422 and the transmission tube 32, and the connecting tube 422 is pulled out of the transmission tube 32, so as to separate the connection of the negative pressure cavity 1 and the drainage bag 4.

[0035] At the same time, in order to maintain the connection of the connecting tube 422 and the transmission tube 32, the transmission tube 32 can also penetrate into the connecting tube 422, and the transmission tube 32 is in interference fit with the connecting tube 422. At this time, the connecting tube 422 is made of elastic material and has certain ductility, so that when the transmission tube 32 penetrates into the connecting tube 422, the connecting tube 422 can wrap the transmission tube 32 to prevent the transmission tube 32 from falling off. When the transportation of the drainage liquid is completed, a certain force is applied to separate the transmission tube 32 and the connecting tube 422, and the transmission tube 32 is pulled out of the connecting tube 422, so as to separate the connection of the negative pressure cavity 1 and the drainage bag 4.

[0036] When the negative pressure drainage liquid specimen collection bottle is not used, the seal of the collection bottle needs to be maintained to ensure the negative pressure environment in the negative pressure cavity 1. Or when the negative pressure drainage liquid specimen collection bottle completes the collection of the drainage liquid, the seal of the collection bottle also needs to be maintained to prevent the drainage liquid from spreading to the external environment and causing pollution to the external environment, and also to prevent the external environment from polluting the drainage liquid in the collection bottle. Therefore, the connector 3 further comprises a bottle plug 34 which is detachably installed in the snap ring 31, that is, before the collection bottle is used, the bottle plug 34 is installed in the snap ring 31 to maintain the sealed environment in the collection bottle. When the collection bottle needs to be used to collect the drainage liquid, the bottle plug 34 is pulled out of the snap ring 31, and then the transmission tube 32 is connected with the connecting tube 422 to ensure that the drainage liquid can be transmitted from the bag body 41 to the negative pressure cavity 1. When the transmission of the drainage liquid is completed, the connection between the transmission tube 32 and the connecting tube 422 is disconnected, and then the bottle plug 34 is filled into the snap ring 31 again to isolate the negative pressure cavity 1 from the external environment, preventing the drainage liquid from leaking to the external environment and also avoiding the pollution of the external environment to the drainage liquid.

[0037] Further, in order to avoid the bottle plug 34 from falling and being lost when the bottle plug 34 is pulled out, the bottle plug 34 needs to be maintained near the collection bottle, so as to be filled into the engaging ring 31 in time after the drainage fluid is delivered, therefore the connector 3 further comprises a lanyard 35, one end of the lanyard 35 is fixed on the bottle cap 2, and the other end of the lanyard 35 is fixed on the bottle plug 34, when the bottle plug 34 is pulled out from the engaging ring 31, the lanyard 35 limits the moving range of the bottle plug 34, and fixes the bottle plug 34 near the collection bottle, so as to avoid the bottle plug 34 from falling to other positions and being lost, when the bottle plug 34 needs to be installed into the engaging ring 31, only the bottle plug 34 needs to be grabbed and filled into the engaging ring 31, and there is no need to find an additional place to store the bottle plug 34, and there is no need to find the position of the bottle plug 34 when the bottle plug 34 needs to be used.

[0038] Generally, the collection of drainage fluid at one time only collects a fixed amount of drainage fluid, so when the drainage fluid is collected, the collection amount of the drainage fluid of the collection bottle needs to be controlled, therefore the negative pressure cavity 1 is provided with a scale line 11, and whether the collection amount of the drainage fluid reaches the requirement is judged through the scale line 11, therefore when the drainage fluid in the negative pressure cavity 1 reaches the specified scale line 11, the valve switch 421 is closed, the delivery of the drainage fluid is stopped, then the transmission pipe 32 and the connecting pipe 422 are separated, the bottle plug 34 is filled into the engaging ring 31, and the collection of the drainage fluid is completed.

[0039] In summary, when the drainage fluid needs to be collected by using the drainage fluid specimen collection bottle with negative pressure in the embodiment, the bottle plug 34 needs to be taken out from the engaging ring 31, then the transmission pipe 32 and the connecting pipe 422 are connected, the valve switch 421 is opened, so that the bag body 41 is communicated with the negative pressure cavity 1, then the drainage fluid flows from the bag body 41 to the negative pressure cavity 1 under the action of the negative pressure in the negative pressure cavity 1, when the drainage fluid in the negative pressure cavity 1 reaches the specified scale line 11, the valve switch 421 is closed, the transmission pipe 32 and the connecting pipe 422 are disconnected, the connecting pipe 422 is pulled out from the engaging ring 31, then the bottle plug 34 is filled into the engaging ring 31, and the sealing of the negative pressure cavity 1 is maintained, so as to complete the collection of the drainage fluid.

[0040] It should be understood that the application of the utility model is not limited to the above examples, and those skilled in the art can make improvements or changes according to the above description, and all these improvements and changes shall belong to the protection scope of the utility model claims.
