Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical devices, specifically to a dustproof carbon dioxide absorption tank. Background Technology
[0002] Currently, the breathing circuit in anesthesia machines is a gas supply device connected to the patient. The anesthesia machine provides the patient with an anesthetic gas mixture through the breathing circuit. To prevent the patient from re-inhaling exhaled carbon dioxide during respiration, a carbon dioxide absorber is installed on the anesthesia breathing circuit. This absorber removes carbon dioxide from the breathing circuit and allows the patient to inhale it again. The carbon dioxide exhaled by the patient is removed by a chemical reaction between the absorbent in the absorber and the carbon dioxide in the breathing circuit.
[0003] However, carbon dioxide absorption canisters require replacement of the carbon dioxide absorbent (soda lime) when it becomes ineffective. During replacement, the dust from the carbon dioxide absorbent is easily stirred up, which is detrimental to the health of anesthesiologists and can also cause environmental pollution.
[0004] Currently, the soda lime in the carbon dioxide absorption tank needs to be manually poured from the soda lime storage tank into the carbon dioxide absorption tank. Because the opening of the carbon dioxide absorption tank is relatively large while the opening of the soda lime storage tank is relatively small, dust is easily generated, which causes environmental pollution in the operating room and affects patients and doctors. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a dustproof carbon dioxide absorption tank.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A dustproof carbon dioxide absorption tank, comprising:
[0008] An absorption tank having a filling port, wherein the upper side of the absorption tank is provided with a detachable connection port for connection with an anesthesia machine;
[0009] A dust cover, which runs vertically through the entire structure, includes a first end connected to the absorption tank, a second end detachably connected to the soda lime storage tank, and a cover connecting the first and second ends.
[0010] The first end is equipped with a sealing ring that connects to the absorption tank, and the second end is a contraction opening with a tightening device.
[0011] The cover is made of fabric.
[0012] The sealing ring at the first end is detachably connected to the absorption tank.
[0013] The sealing ring at the first end is interference-fitted with the absorption tank.
[0014] The second end is provided with an elastic band in the circumferential direction.
[0015] The sealing ring is located above the maximum scale line of the absorption tank.
[0016] The filling port is located on the upper or lower side of the tube body.
[0017] The beneficial effects of this utility model are as follows: By additionally setting a dust cover outside the carbon dioxide absorption tank, when it is necessary to add soda lime, it is only necessary to stretch the dust cover and connect the second end to the outlet of the soda lime storage tank. The connection between the two is made more reliable by using a tightening device, soda lime can be added without causing dust to overflow. After the addition is completed, it is only necessary to pull down and fold the second end to the outside of the absorption tank, which does not affect the installation and use of the carbon dioxide absorption tank.

[0019] Figure 2 This is a schematic diagram of the structure of Embodiment 2 of this utility model.
[0020] Figure 3 This is a structural schematic diagram of Embodiment 3 of the present invention. Detailed Implementation
[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0022] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
[0023] This utility model provides a dustproof carbon dioxide absorption canister. This application can improve the existing carbon dioxide absorption canister by adding a dust cover. The improvement cost is low, and it does not require updating the existing anesthesia machine. At the same time, it can be adapted to different types of carbon dioxide absorption canisters and has a wide range of applications.
[0024] The absorption tank 100 has a filling port and a detachable connection port on the upper side for connection with an anesthesia machine.
[0025] The dust cover 200 is arranged through the top and bottom. It includes a first end 210 connected to the absorption tank 100, a micro-movement second end 220 detachably connected to the soda lime storage tank, and a cover connecting the first end 210 and the second end 220. The first end is provided with a sealing ring connected to the absorption tank, the second end is a contraction opening, and the second end is provided with a tightening device 230.
[0026] The tightening device can be a pull-out strap, cable tie, or other binding and tightening structure, or a Velcro or other adhesive structure, used to adjust the fixed diameter of the second end.
[0027] The sealing ring is made of rubber and can be directly fixed and supported by the cover, that is, it is wrapped by the cover. At the same time, the size of the sealing ring is adapted to the outer diameter of the absorption tank, so that the two can be sealed when connected, and its installation is relatively convenient.
[0028] The cover is made of fabric, which is easy to use. By folding it up, both the first and second ends can be folded back to the outside of the absorption tank, so as not to affect the normal use of the carbon dioxide absorption tank. Moreover, if a leak is found at the connection between the two during use, the second end can be unfolded and the connection between the two can be sealed by using a tightening device, which can further achieve airtightness between the two and further prevent dust from overflowing.
[0029] The sealing ring of the first end 210 is press-fitted with the absorption tank 100. The press-fit is easy to install and fix, and its position on the absorption tank can be adjusted.
[0030] The second end 220 is provided with an elastic band in the circumferential direction, which further improves the sealing performance at the connection with the soda lime storage tank, and at the same time the elastic band facilitates the adjustment of the opening size of the second end.
[0031] The sealing ring is located above the maximum scale line 110 of the absorption tank 100, so as not to affect the observation during material addition.
[0032] Figure 1 The embodiment shown is an absorption container with a handle, and its sealing ring is generally positioned above the scale line so as not to obstruct observation.
[0033] and Figure 2 The embodiment shown is an absorption tank without a handle, and its sealing ring can be close to the scale line, or the sealing ring can be used directly as the scale line.
[0034] Figure 3The embodiment shown is an absorption tank with the filling port on the lower side. Its sealing ring is set above the bottom opening. After filling is completed, the cover can be pulled up and stored on the side.
[0035] When using it, open the bottom cover of the absorption tank, stretch the second end and connect it to the discharge port of the soda lime storage tank. After filling, close the bottom cover and retract the cover.
[0036] The embodiments should not be regarded as limitations on the present invention, but any improvements made based on the spirit of the present invention should be within the protection scope of the present invention.
