Description

Technical Field

[0001] The utility model relates to the technical field of medical clinical equipment, in particular to a quantitative liquid taking device for gargling. Background Art

[0002] Oral mucositis refers to inflammatory and ulcerative reactions in the oral cavity. Due to the use of high-dose chemotherapy drugs during the pretreatment period, oral mucosal epithelial cells are severely damaged in hematopoietic stem cell transplant patients. Repair barriers and defects in the mucosal barrier allow the invasion of microorganisms such as bacteria and fungi, and the involvement of inflammatory factors further aggravates the damage to the mucosal epithelium. Therefore, oral mucositis is a common and serious complication in hematopoietic stem cell transplant patients, with an incidence rate as high as 43.7%-100%. Therefore, in the clinical nursing process, gargling as an auxiliary method for the prevention and treatment of oral mucositis has reached a consensus in clinical practice that gargling with mouthwash has good efficacy and practicality, forming a nursing routine for the prevention and care of oral mucositis in hematopoietic stem cell transplant patients and has been widely used. Clinically, 2-5 types of mouthwashes are used to gargle alternately every two hours to prevent oral mucositis.

[0003] When gargling, medical staff need to pour about 20 ml of mouthwash from the mouthwash bottle into a measuring cup and then gargle; after each use of the measuring cup, the measuring cup needs to be disinfected for next use; at the same time, since the patient needs to gargle again every two hours, multiple measuring cups need to be used, which is cumbersome and time-consuming to clean and disinfect a large number of measuring cups.

[0004] There are related technologies in the prior art that use a negative pressure suction mechanism to achieve mouthwash absorption; for example, a mouthwash aspirator disclosed in the patent announcement number CN219763610U and the announcement date September 29, 2023, includes a suction piece, a liquid absorption piece and a liquid storage box, and the liquid storage box is connected to the suction piece and the telescopic tube respectively; by placing the liquid absorption piece inside the oral cavity, the mouthwash can be sucked into the liquid storage box by pinching the suction piece, which is a rapid absorption of liquid through a negative pressure airbag ball. Another example is the negative pressure liquid suction tube attached to the popular children's antipyretic medicine on the market. The liquid suction tube is provided with a scale, and the upper end of the liquid suction tube is sealed and connected to a negative pressure liquid absorption airbag, and a quantitative liquid is absorbed by negative pressure. It is similar to the above-mentioned patented technical solution, and both use the negative pressure airbag sphere to achieve rapid absorption of liquid; however, this type of liquid suction tube needs to be cleaned before use. In a laminar flow chamber with high sterility requirements, if this structure is used directly, there is still a cumbersome procedure of cleaning and disinfection after each use. Utility Model Content

[0005] In order to solve the shortcomings of the prior art, the utility model provides a gargle quantitative liquid taking device which does not require cleaning and is easy to use.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A quantitative liquid collection device for gargling, comprising a negative pressure suction airbag and a disposable liquid storage tube, wherein the bottom of the negative pressure suction airbag is open and fixedly bonded with a connecting tube; the liquid storage tube consists of a tapered portion with a gradually decreasing diameter at the lower part, a cylindrical liquid storage portion in the middle part and a connecting tube portion arranged at the upper part, the top of the connecting tube portion is open and the open portion is detachably connected to the lower end of the connecting tube, the tapered portion is provided with a tube opening at the bottom which is sealed and bonded with a liquid inlet tube, and the lower end of the liquid inlet tube extends downward by 5-8 cm.

[0008] Preferably, the negative pressure suction airbag is made of elastic rubber, the connecting tube is made of transparent plastic, and the liquid storage tube is made of transparent polymer material polyethylene.

[0009] Preferably, the thickness of the conical portion, the liquid holding portion and the liquid inlet pipe of the liquid holding pipe are all 0.5-0.6 mm, and the thickness of the connecting pipe portion is 10-20 mm.

[0010] Preferably, the outer peripheral edge of the upper end of the connecting pipe portion is provided with vertical anti-slip grooves.

[0011] Preferably, a measuring scale is provided on the body of the liquid containing tube.

[0012] Preferably, the outer periphery of the lower end of the connecting tube is wrapped with a silicone sealing layer on one side, and the thickness of the silicone sealing layer gradually decreases from top to bottom.

[0013] Preferably, the outer surface of the connecting pipe is in the form of an external thread, and the inner wall surface of the upper open end side of the connecting pipe portion is an internal thread that matches the external thread.

[0014] The beneficial effects of the utility model are:

[0015] The utility model of the quantitative mouthwash liquid taking device adopts the combination of the negative pressure suction airbag quick suction mechanism and the detachable liquid holding tube. After pinching the negative pressure suction airbag to suck the quantitative mouthwash liquid, the lower end of the liquid holding tube is directed toward the human oral cavity, and the airbag is released. Since the patient uses the mouthwash liquid more frequently, after the first use of the liquid taking device, the part of the liquid inlet tube mouth close to the human oral cavity can be cut off with sterile scissors, and the liquid holding tube can continue to be used 1-2 times; after the liquid holding tube completes the liquid taking operation 2-3 times, it can be directly unscrewed from the connecting tube and discarded.

[0016] While ensuring low cost and safety in use, the device does not need to be repeatedly cleaned and disinfected, which reduces the labor cost of medical staff and thus improves their work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example

[0021] Figure 1 The utility model is a schematic diagram of the structure of a quantitative liquid dispensing device for gargling.

[0022] The present embodiment provides a quantitative liquid-taking device for gargling, comprising a negative pressure suction balloon 1 and a disposable liquid-collecting tube 2, wherein the bottom of the negative pressure suction balloon 1 is open and a connecting tube 3 is fixedly bonded thereto; the liquid-collecting tube 2 is composed of a tapered portion 20 with a gradually decreasing diameter at the lower portion, a cylindrical liquid-collecting portion 21 in the middle portion, and a connecting tube portion 22 arranged at the upper portion, wherein the top of the connecting tube portion 22 is open and the open portion is detachably connected to the lower end of the connecting tube 3, the tapered portion 20 is provided with a tube opening at the bottom to which a liquid inlet tube 4 is sealed and bonded, and the lower end of the liquid inlet tube 4 extends downward by 5-8 cm.

[0023] The negative pressure suction airbag 1 is made of elastic rubber, the connecting tube 3 is made of transparent plastic, and the liquid holding tube 2 is made of transparent polymer material polyethylene. As a disposable part, in order to reduce the use and cost of plastic, the thickness of the conical part 20, the liquid holding part 21 and the liquid inlet tube 4 of the liquid holding tube 2 are all 0.5-0.6mm. The plastic tube of this thickness can ensure the smooth liquid extraction and minimize the use of plastic; and the connecting tube 3 connected to the negative pressure suction airbag 1 requires strong plasticity, for this reason, the thickness of the connecting tube part 22 is set to 10-20mm.

[0024] The outer peripheral edge of the upper end of the connecting pipe portion 22 is provided with vertical anti-slip grooves 23 to facilitate the screwing operation.

[0025] The body of the liquid holding tube 2 is provided with a measuring scale 24, which can intuitively perform quantitative liquid extraction.

[0026] In order to ensure the sealing effect of the connecting pipe and the connecting pipe part, Figure 2 As shown, the outer periphery of the lower end of the connecting pipe 3 is wrapped with a silicone sealing layer 5 on one side. The thickness of the silicone sealing layer 5 gradually decreases from top to bottom, and the thickness is 0.1-0.4mm.

[0027] The outer surface of the connecting tube 3 is in the form of an external thread, and the inner wall surface of the upper open side of the connecting tube portion 22 is an internal thread that matches the external thread. When the disposable liquid storage tube is to be discarded, it can be directly loosened and disassembled.

[0028] When using the utility model, the medical staff can pinch the negative pressure suction air bag to absorb a certain amount of mouthwash, then point the lower end of the liquid-filling tube toward the human oral cavity and release the air bag. Since patients use mouthwash frequently, after using the liquid-filling device for the first time, sterile scissors can be used to cut off the part of the liquid-filling tube near the human oral cavity, and the liquid-filling tube can be used 1-2 more times; after the liquid-filling tube completes the liquid-filling operation 2-3 times, it can be directly unscrewed from the connecting tube and discarded.

[0029] The liquid collection device of the utility model combines a non-disposable negative pressure suction airbag with a disposable liquid containing tube structure, which ensures fast and accurate liquid collection and realizes a one-time, two-time or three-time change operation mode. There is no need to repeatedly clean and disinfect the device, thereby reducing the labor cost of medical staff.
